Why I’m mapping the carbon stored in regrowing Amazonian forests

As we navigate our way out of the global medical pandemic, many are calling for a “green economic recovery”. This green recovery should be at the forefront of many discussions as world leaders, policy makers, scientists and organisations are preparing for the 26th Conference of the Parties (COP26) due to take place in November this year in Glasgow, UK. This conference will once again try to unite the world to help tackle the next and even larger global emergency, the Climate Emergency.

In recent years, the conversations around the Climate Emergency have increased dramatically with many individuals, groups, companies and governments aiming to tackle this emergency, in part, through replanting, restoring and reforesting large areas of land.

But what if we let forests regrow back naturally? How much carbon can they absorb from the atmosphere? 

As part of my PhD research at the University of Bristol, I have been looking at naturally regrowing forests in the Brazilian Amazon rainforest. These forests are known as “Secondary forests” and regrow on land that has previously been deforested and used for agricultural or other purposes and has since been abandoned, allowing the natural vegetation to return.

Secondary Forests in the Brazilian Amazon are expected to play a key role in achieving the goals of the Paris Agreement. They have a large climate mitigation potential, given their ability to absorb carbon up to 11 times faster than old-growth forests. However, the regrowth of these secondary forests is not uniform across the Amazon and is influenced by regional and local-scale environmental drivers and human disturbances like fires and repeated deforestations.

I worked with numerous scientists from Brazil and the UK to determine the impact of different drivers on the regrowth rates of the secondary forests, using a combination of satellite data. The key datasets we needed were:

What we did

We combined the satellite data maps and overlayed them to extract information on the carbon stored in relation to the forest age to model the regrowth rate with increasing age. We overlayed the information of key environmental drivers and human disturbances to see if and how these factors impact the regrowth rates.

What we found out

Overall, we found that the environmental conditions in Western Amazon enable secondary forests to regrow faster. Here the land received lots of rainfall and does not experience much drought. In the eastern parts of the Amazon, where the climate is drier and experiences more drought, the regrowth rates were up to 60% lower.

Figure 2: Schematic summary of the main results from the paper, highlighting the spatial patterns of regrowth dependent on both climate and human disturbances. The map in the middle shows the regions of secondary forest in the Brazillian Amazon and the four panels correspond to these regions.

In addition to this, we found that the regrowth rates were reduced even further by as much as 80% in eastern regions if the forests were subject to human activities like burning and repeated deforestations before the land was finally abandoned.

What it all means

Our results show the importance of protecting and expanding secondary forest areas to help us meet the Paris Agreement Targets. Our regrowth models can be used to help determine the contribution of current and future regrowing forests in the Brazilian Amazon in a spatial manner.

We found that in 2017, the secondary forests in the Brazilian Amazon stored about 294 Terragrams Carbon aboveground (that excludes carbon stored in roots and soils). However, this number is equivalent to about 0.25% of the carbon that is already stored in Amazon’s old-growth forests. Limiting carbon emissions through deforestation and degradation through burning of old-growth forests is therefore extremely important to help tackle the Climate Emergency.

We calculated that the annual carbon absorbed by the present secondary forest area in the Amazon is enough to contribute to about 5% of Brazil’s pledged contribution to the Paris Agreement by 2030. This number may seem small, but the area covered by the Amazonian secondary forests is currently equivalent to less than 2% of the whole of Brazil. If the area of secondary forest were to be expanded this would bring with it numerous co-benefits such as generating income to landowners and re-establishing ecosystem services.

In December 2020, many countries submitted updates to their so-called Nationally Determined Contributions (NDC), a country’s individual contributions to the Paris Agreement, this included Brazil. However, Brazil’s updated NDC no longer includes a clear position on reforestation, restoration and eliminating illegal deforestation.

At a time when we have all seen and felt the impacts of a true global emergency such as the COVID-19 pandemic, it becomes easier to imagine the potential impacts of climate change if left at the back of politician’s agendas. In the run up to COP26 it is now more important than ever to raise, not lower ambitions as we continue to tackle the global Climate Emergency.

Reflections and insights on COP24

COP24 plenary. Image credit Wikimedia Commons Doman84.

The topic of climate change has fascinated me ever since the age of 17 and I haven’t looked back since then because it is something that is beyond my passion. I completed my Bachelors in Environmental Science at the University of Nottingham and now here at the University of Bristol I am enrolled in Climate Change Science and Policy MSc.

I am also part of a youth-based Climate Change NGO, Malaysian Youth Delegation (MYD), which constantly pushes for more ambitious national and regional climate policies and liaises with the government. The organisation also represents youth climate movement on national and International platforms, educates Malaysian Youth on UNFCCC in relation to Malaysian climate policies and holds Malaysian leaders accountable for their promises. Being in the organisation has taught me about the intricacies involved in climate policies such as the global north-south divide, climate adaptation, mitigation, finance and capacity building.

Being at the University of Bristol has made me intrigued to know more about the science-policy interface that occurs in climate negotiations like COP. I was also intrigued to find out more about how negotiations took place and the role of politics being part and a consequence. I am thankful for Cabot Institute for assisting and funding me with the logistics to my trip to Katowice. During my time at COP24 and aside from tracking negotiations, I was predominantly taking the youth narrative and was working with the organisation I represented – the Malaysian Youth Delegation (MYD) and Youth NGO constituency (YOUNGO).

My experience at COP24 was a profound one, primarily because I saw the subject of climate change coming to life through the form of formal and informal negotiations, high-level meetings and other side events in the premises. This COP was an important one since the draft text for the Paris Agreement Working Programme was supposed to be completed by the end of the conference – the document is vital for the implementation of the Paris Accord that took place in 2015. The two weeks that I’d spent at the COP were some of the most exhilarating and engrossing adventures in the world of climate policy – days often started at 6 am and completed around 2 to 3am the next day leaving a short time to rest each day. At the conference, I attended and observed negotiation sessions, youth constituency meetings, side events related to other aspects of climate change during the day and helped to produce position papers, proposals and write reports for MYD and YOUNGO in the evenings and overnight.

Highlights

One of my main highlights was that I got the chance to meet the Malaysian Minister for Energy, Science, Technology, Environment and Climate Change, Ms. Yeo Bee Yin, and Dr. Gary Theseira, the special functions officer to the minister and a highly experienced negotiator in the UNFCCC. We, the MYD team, attempted to shadow the minister while she was at the conference. Unfortunately, we couldn’t follow the minister as many of her meetings were predominantly “closed door” meaning those meeting not being open to observers. However, the initial purpose of tracking the minister at the conference was to know her views on her unprecedented attendance of a climate conference and how she would take back any outcomes to Malaysia. We also had the opportunity to transcribe Ms. Yeo Bee Yin’s COP speech which can be read here.

Another highlight was having the opportunity to meet my tutor, Cabot Institute theme co-lead for Environmental Change research, Dr. Jo House, at the conference too.  We visited the Polish “coal exhibition” center together where chunks of coal were stacked up. They were termed “clean coal” which were made to supposedly reduce the environmental impact of its combustion as compared to regular coal.

I was also presented with an opportunity to deliver an intervention (a term used in COPs where non-country stakeholders provide their expressions to the chair of a respective meeting) on behalf of YOUNGO. Due to time constraints and other internal reasons, this fell through but the position paper I was about to present was handed over as a written draft to the respective chair of the meeting.

The most important highlight of the conference  was the production of the 133-page rulebook for the implementation of Paris Agreement, which was unanimously adopted at the conference.  This contains the framework for the various articles and implementation modalities mentioned in the Paris Agreement.

The next COP will take place in Chile from 11-22 November 2019 with the pre-COP happening in Costa Rica at an earlier date. COP25 and the intersessional meetings before 2020 will make the rulebook less ambiguous to enact the Paris accord. The United Kingdom has also officially submitted a bid to the UNFCCC to host COP26. This conference would be crucial since it would be the first COP during the implementation period of the Paris agreement – the UK would have to successfully host nations and lead it to a productive outcome considering the interest of various parties.

The most deliberate question in our minds, as youth representatives, is that after the publication of the IPCC’s Special Report, will the Earth’s average surface temperature stay below 1.5C since pre-industrial levels?

COP24: ten years on from Lehman Brothers, we can’t trust finance with the planet

 

Listen! Andy Rain/EPA

Lehman Brothers filed for bankruptcy on September 15, 2008. The investment bank’s collapse was the drop that made the bucket of global finance overflow, starting a decade of foreclosures, bailouts and austerity.

The resulting tsunami hit the global economy and public sector, discrediting finance and its attempts to extract large rents from every aspect of the economy, including housing and food. An alternative was urgently needed.

Ten years later, private finance and large investors will play a central role at the COP24 in Katowice, Poland, and in the full implementation of the 2015 Paris Agreement.

Representatives from pension funds, insurance funds, asset managers and large banks will attend the meeting and lobby governments, cities and other banks to favour investments in infrastructure, energy production, agriculture and the transition towards a low-carbon economy.

Has finance cleaned up its act?

There is a US$2.5 trillion gap in development aid which needs to be filled if poor countries can adequately mitigate the effects of climate change. With little enthusiasm among rich countries to stump up, the role of private finance is inevitable. Policy makers trust financial capital as our best hope of securing investment to avoid the catastrophic warming beyond 1.5°C.

This has been the case for a while – the first announcement came at the UN Climate Summit in 2014, when a press release on the UN website said the investment community and financial institutions would “mobilise hundreds of billions of dollars for financing low-carbon and climate resilient pathways”.

Since then, networks that stress the role of private finance in rescuing the planet have multiplied, including the Climate Finance session at the Sustainable Innovation Forum, which will also take place in Katowice, on December 9-10 2018.

It is difficult to ignore that a strong reliance on private finance means putting the future of Earth in the hands of individuals and institutions that brought the global economy to the verge of collapse. It may be partially true that some are divesting from fossil fuels and funnelling their money into better projects. But before we pin our hopes on finance to solve climate change, there are some things we need to ask ourselves.

Difficult questions for COP24 negotiators

How did we get to a point in history where it is taken for granted that public money alone can never be sufficient to finance our transition from fossil fuels? Is it an objective condition with no clear causation and responsibility, or something else?

What about the fact that global military spending in 2017 reached US$1.7 trillion while poor countries promised funding for climate change adaptation and mitigation in 2015 are still waiting?

COP24: climate protesters must get radical and challenge economic growth


What about the cost of bailouts to the financial sector, which in the UK alone has been estimated at US$850 billion? As Michael Lewis noted in his boomerang theory, states that have propped up financiers with public money are now asking those same financiers to step in and do the job that states should do. And this leads to the second consideration.

Climate change is historically, politically and socially complex. Although sustainable finance is not presented as the sole solution, analysing its role produces a series of strategic short circuits.

Climate change and migration in Bangladesh — one woman’s perspective


It oversimplifies and depoliticises the response to climate change. It legitimises the idea that sustainability can be achieved within continuous growth and expansion, which are essential to the survival of the financial sector.

It rewrites the way we think about our planet in the vocabulary of finance and its obsession for a return on investment. It marginalises any claim to address climate change based on present and historical injustices, redistribution and bottom-up projects organised by ordinary people.

It accepts that the financial way of defining sustainability and its achievements are inherently aligned with the rights, interests and needs of people and the planet.

Finance may be a partner in the fight against climate change, but it is certainly not a partner motivated by altruism. It’s motivated by generating profit from the transition. It is therefore unsurprising that energy generation, railways, water management and other forms of climate mitigation have been identified as priorities for sustainable finance.

Action on climate change has to involve standing up to the Wall Street Bull. Quietbits/Shutterstock

Fighting climate change on Wall Street’s terms

Wall Street can find large returns by investing in the transition to “greener” infrastructure, including the not-so-green Chinese green belt and road and dams like the Belo Monte, a project that originally applied for carbon credits and was labelled as a sustainable investment. Green bonds can help cities finance projects to reduce their environmental impact or adapt to climate change.

However, if money is the driver, we should not expect private investors to have any interest in projects that won’t generate a sufficient return, but would benefit people or cities that cannot pay for the service or for the debt, or that would protect vulnerable people from climate change. If climate change is fought according to the rules of Wall Street, people and projects will be supported only on the basis of whether they will make money.

Ten years ago, the world saw that finance had permeated every aspect of the global economy. Back then, it was clear that financial interests could not build a better and different world. Ten years later, COP24 should not legitimise large financial investors as the architects of a transition where sustainability rhymes with profitability.The Conversation

My Reflections on COP23 – challenges, inspiration, and hopes for the future

I had the great pleasure of attending COP21 in Paris, 2015. The air was full of anticipation, hope and a clear sense of urgency. The achievements of the conference were remarkable and as a climate scientist I felt a degree of reassurance (albeit uneasy reassurance) that there was now a serious global commitment that may lead to a turning point in climate action.

Two years on, I was therefore excited to attend COP23 in Bonn as part of the IPCC (Intergovernmental Panel on Climate Change) delegation, to see how things were progressing.

I was immediately struck by the difference. The negotiations here were largely focussed on how to implement the Paris Agreement. The discussion were necessarily more technical, but less awe-inspiring, ‘nuts and bolts’. Without the big deadline and the huge public pressure to sign a global agreement, it seems things in the negotiations moved slowly, and there was an air of frustration amongst some negotiators and campaigners.

Despite the slow pace in the negotiations, this blog shares some real highlights from the week, as well as some low lights, alongside my thoughts on proceedings.

Last one out

COP23 started with an announcement from Syria that they would sign the Paris Agreement, leaving the USA isolated as the only country that will not be part of the Agreement – Trump’s announcement to withdraw from the Agreement offers a stark reminder of the impact of domestic political change on international initiatives.

The #wearestillin campaign has caught
the imagination of  businesses and civil
society alike.

It was however encouraging to go to the launch of the US #wearestillin campaign – a collection of states, cities, businesses, NGOs, civil society etc that are willing to make a commitment to climate change despite Trump pulling out of the Paris Agreement. With Bloomberg having offered to cover for the USA’s climate finance and on our side of the pond, Macron offering to cover their commitments to the IPCC (with a little top up also from the UK government).

Despite anticipating that the US delegation might join Saudia Arabia and others to stall progress, they sent the usual negotiators who were being helpful in the side-lines, if quiet during decisions. China, on the other hand, were not being as constructive as they could have…..

Climate finance, historical responsibilities and ability to pay.

Finance is always one of the biggest sticking points of negotiations, and this year was no different. China (and others) want America to put up large sums of climate finance (to fund adaptation and mitigation in other countries), taking historical responsibility for their emissions, but America will not do this. Even Obama, who strongly supported Paris, would not agree to take responsibility for emissions before there was widespread acceptance of on climate change being anthropogenic.

In the past, developed and developing countries had differentiated responsibilities for mitigation of climate change, reflecting their different historical contributions and capabilities. Only “Annex I” (“developed”) countries such as the EU, USA and Canada had mitigation targets and financial opbligations under the Kyoto Protocol. Economies in Transition (such as China) and developing countries did not. Moving forward in Paris, the process of countries setting their own targets (Nationally Determined Contributions) gave all countries responsibilities but also control over their own action, reducing the need for formalised differentiation.

China remains keen to retain formal differentiation, but many at the conference began to question the legitimacy of China’s appeals for finance and differentiation when they have become the largest pollution nation (albeit with lower per capita emissions that America) and one of the most rapidly growing economies.

Reconnecting with the lived experience of climate change 

There was an overwhelming number of science talks at a huge verity of side events. For me though, the best thing about COP was the opportunity to mix with people, hear stories and go to talks that I wouldn’t normally get the chance to. It takes me away from my number crunching to hear how people are experiencing climate change, to talk about the realities of adaption and mitigation, to remind us how the world really works outside of computer models.

Talking to a young African man and an indigenous Guatemalan woman about how people are experiencing climate change now, they explained that people often don’t really know that that is the reason their crops have failed three years running, or there are more regular storms of higher intensity, or their houses are washing away. They are worrying how to feed themselves and pay for their kids to go to school. They are not concerned with how they can mitigate climate change, but how they can live.

Developing countries and indigenous groups attended in force, raising awareness of how climate change is affecting them now, and demanding action. These groups reconnected us with the urgency of the task at hand, and with the talks under the Presidency of Fiji this year, there was a loud and passionate voice from the Pacific Islands. Many islanders are already having to leave their homes due to sea level rise, salt water inundation of crops and drinking water aquifers – not to mention the series of increasingly frequent and devastating storms. One of the Island country negotiators told me that many other countries were keen to gain the favour of the Pacific Islands as the many countries (and therefore many votes) could lead them to become a powerful influencer.

A triumph or misfortune of participation? 

One news article noted the five largest delegations were from African countries (nearly 500 from Cote d’Ivoire). While on the surface this is a major accomplishment, there were mutterings in the conference from younger African delegates that some senior colleagues had little interest in proceedings. While the importance of gender issues and climate was a major issue on the table at COP23, the proceedings also reflected other revelations of sexual misconduct with complaints of senior powerful male figures taking advantage of young female staff.

Some final thoughts 

All in all, I have not come away from COP23 with the sense of achievement and exhilaration at the end of COP21 Paris, but a sense of urgency of the need to make it happen faster.

As Kevin Anderson from Tyndall said to me – we have known about this for some time now and yet we are failing, every one of us, to make anything happen at the scale and rate it needs to.

As I claw for answers on how to achieve this, I’m reminded that this year at COP there was a focus on youth. I saw some amazing youth speakers and participants, including one of our 3rd year undergraduate geography students. I also met two of our recent MSc graduates, one who was on the Mexican Delegation and one working for and NGO Climate Action Network.

I take great inspiration from these hugely talented young people, and they, alongside the impassioned and increasingly powerful voices of developing nations, offer hope. Whilst the responsibility for dealing with the implications of climate change should not rest solely in their hands – the devolution of power/ resource to those with fresh ideas and approaches could be exactly what we need to catalyse change.

In defence of science: Making facts great again

“We must not let rhetoric or vested interests divert us from what we know is the right course of action.”

From across the Atlantic, the European scientific community is watching warily as our American colleagues endure increasingly politicised attacks on their work and on the very foundation of evidence-based science.

President Donald Trump‘s decision earlier this month to withdraw the United States from the historic Paris Agreement on Climate Change – a decision condemned by heads of state, businesses, mayors and ordinary people in the US and the world over – epitomised this contempt for the facts from some within the political sphere.

We can, to some degree, relate, as many European scientists – and particularly those who research climate change and its impacts, as I do – have been forced to confront the politicisation of their disciplines, the distortion of their research and the promotion of “alternative facts” and vested-interest propaganda.

In fact, just two months ago at the annual General Assembly of the European Geosciences Union, for the first time in the body’s history, we debated issues around existential threats to science in general, the integrity of the scientific community, trust in science and what we can do to ensure that evidence-based science forms the basis for informed decisions and debate by policymakers and the public.

Later this month, we’ll watch as some of our American colleagues gather for the annual Broadcast Meteorology Conference of the American Meteorological Society, which will include in its programme a short course explicitly focused on the communication of climate science.

Never has accurate, fact-based communication of climate science been more urgently needed, and in modern history, it has rarely been so compromised. There is a clear trend, particularly evident in the US, of a growing distrust of “experts” who are branded as intellectual elites, rooted in a populist backlash towards the establishment.

This goes all the way up the rungs of government to the American president himself, who has called climate change a “hoax” and in his first 100 days in office has moved to curb spending on climate and earth science research and is overseeing an agency-wide scrubbing of climate science out of federal websites and publications.

As he announced the US withdrawal from the Paris Agreement on June 1, Trump also left himself open to accusations of misrepresenting climate science to suit his own political objectives: after the US president quoted a figure from a Massachusetts Institute of Technology (MIT) study to support his argument that the Paris Agreement is ineffectual, MIT officials – including one of the study’s authors – declared that Trump had misunderstood their work and that they did not support a US withdrawal from the agreement.

The science of climate change, however, is clearer than ever. We see the fingerprints of human-induced global warming on more and more long-term climate trends. In the US and throughout the world, for instance, warmer temperatures are amplifying the intensity, duration and frequency of many weather events, none more evident than extreme heat. Western states have suffered through record numbers of heat waves since the turn of the century, with overnight temperatures often at historical highs. This is particularly dangerous as it doesn’t give the human body the necessary relief. Already, these heat waves are costing lives, and the scientific link between human-induced global warming and heat waves is crystal clear. The European heat wave of 2003 is estimated to have caused 35,000 premature deaths and was very likely a consequence of human interference with the climate system.

By listening to the best available science on climate change, we can better prepare for its impacts. By ignoring, censoring, or shunning our scientists, we put more Americans at risk. The alternative to informed decision-making is uninformed decision-making. Without evidence-based science, decisions of vital importance to humanity will be made founded in prejudice, emotion and ignorance. That is no way to run the planet. It is no way to plan our future.

Besides helping prepare for the impacts of climate change, science should guide our efforts to minimise them. For these mitigation efforts, the science is telling us that we don’t have much time. In fact, it’s saying that 2020 must be the target for peaking global carbon emissions. We must bend the curve of global greenhouse gas emissions towards a steady decline by the next US presidential election. If emissions continue to rise beyond 2020, the world stands very little chance of limiting global warming below 1.5 degrees Celsius, the threshold set by the Paris Agreement, and a temperature limit that many of the world’s most vulnerable communities consider a threshold for survival.

The world has four short years to reverse our emissions trends to avoid the very real risk of dangerous and irreversible climate change, but we won’t get the policies we need without trusting and relying on the science that tells us that’s so. Science has no political affiliation, nor can it be bent to your will. You don’t renegotiate with physics and you aren’t about to “win” a deal with chemistry. We must not let rhetoric, vested interests or the blind dismissal of the overwhelming scientific consensus divert us from what we know is the right course of action ethically, scientifically and economically.

Forest accounting rules put EU’s climate credibility at risk, say leading experts

**Article re-posted from EURACTIV **


Forest mitigation should be measured using a scientifically-objective approach, not allowing countries to hide the impacts of policies that increase net emissions, writes a group of environmental scientists led by Dr Joanna I House.

Dr Joanna I House is a reader in environmental science and policy at the Cabot Institute, University of Bristol, UK. She co-signed this op-ed with other environmental scientists listed at the bottom of the article.

When President Trump withdrew from the Paris Agreement, the EU’s Climate Commissioner, Miguel Arias Cañete spoke for all EU Member States when he said that, “This has galvanised us rather than weakened us, and this vacuum will be filled by new broad committed leadership.” The French President, Emmanuel Macron, echoed him by tweeting, “Make our planet great again”.

But as the old saying goes, ‘If you talk the talk, you must walk the walk,’ and what better place to start than the very laws the EU is currently drafting to implement its 2030 climate target under the Paris Agreement. This includes a particularly contentious issue that EU environment leaders will discuss on 19 June, relating to the rules on accounting for the climate impact of forests.

Forests are crucial to limiting global warming to 2 degrees Celsius. Deforestation is responsible for almost one tenth of anthropogenic carbon dioxide (CO2) emissions, while forests remove almost a third of CO2 emissions from the atmosphere.

In the EU, forests currently grow more than they are harvested.  As a result, they act as a net ‘sink’ of CO2 removing more than 400 Mt CO2 from the atmosphere annually, equivalent to 10% of total EU greenhouse gas (GHG) emissions.

New policies adopted or intended by Member States will likely drive them to harvest more trees (e.g. for the bioeconomy and bioenergy), reducing the sink. The controversy is, in simple terms, if forests are taking up less CO2 due to policies, should this be counted?

Based on lessons learnt from the Kyoto Protocol, the European Commission proposed that accounting for the impacts of forests on the atmosphere should be based on a scientifically robust baseline. This baseline (known as the ‘Forest Reference Level’) should take into account historical data on forest management activities and forest dynamics (age-related changes). If countries change forest management activities going forward, the atmospheric impact of these changes would be fully accounted based on the resulting changes in GHG emissions and sinks relative to the baseline. This approach is consistent with the GHG accounting of all other sectors.

Subsequently, some EU member states have proposed that any increase in harvesting, potentially up to the full forest growth increment, should not be penalised. This would be achieved by including this increase in harvesting, and the related change in the net carbon sink, in the baseline.

As land-sector experts involved in scientific and methodological reports (including for the Intergovernmental Panel on Climate Change, IPCC), in the implementation of GHG inventory reports, and in science advice to Governments, we have several scientific concerns with this approach.

From an atmospheric perspective, a reduction in the forest sink leads to more CO2 remaining in the atmosphere and is thus effectively equivalent to a net increase in emissions. This is true even if forests are managed “sustainably”, i.e. even if harvest does not exceed forest growth.

This is further complicated as the issues are cross-sectoral. Higher harvest rates may reduce the uptake of CO2 by forests, but use of the harvested wood may lead to emissions reductions in other sectors e.g. through the substitution of wood for other more emissions-intensive materials (e.g. cement) or fossil energy. These emission reductions will be implicitly counted in the non-LULUCF sectors.  Therefore, to avoid bias through incomplete accounting, the full impact of increased harvesting must be also accounted for.

Including policy-related harvest increases in the baseline could effectively hide up to 400 MtCO2/yr from EU forest biomass accounting compared to the “sink service” that EU forests provide today, or up to 300 MtCO2/yr relative to a baseline based on a scientific approach (up to two thirds of France’s annual emissions).

If policy-related impacts on net land carbon sinks are ignored or discounted, this would:
 

  • Hamper the credibility of the EU’s bioenergy accounting: Current IPCC guidance on reporting emissions from bioenergy is not to assume that it is carbon neutral, but rather any carbon losses should to be reported under the ‘Land Use, Land-Use Change and Forestry’ (LULUCF) sector rather than under the energy sector (to avoid double counting). EU legislation on bioenergy similarly relies on the assumption that carbon emissions are fully accounted under LULUCF.
  • Compromise the consistency between the EU climate target and the IPCC trajectories. The EU objective of reducing GHG emissions of -40% by 2030 (-80/95% by 2050) compared to 1990 is based on the IPCC 2°C GHG trajectory for developed countries. This trajectory is based not just on emissions, but also on land-sinks. Hiding a decrease in the land sink risks failure to reach temperature targets and would require further emission reductions in other sectors to remain consistent with IPCC trajectories.
  • Contradict the spirit of the Paris Agreement, i.e., that “Parties should take action to conserve and enhance sinks”, and that Parties should ensure transparency in accounting providing confidence that the nationally-determined contribution of each country (its chosen level of ambition in mitigation) is met without hiding impacts of national policies.
  • Set a dangerous precedent internationally, potentially leading other countries to do the same (e.g. in setting deforestation reference levels). This would compromise the credibility of the large expected forest contribution to the Paris Agreement.

The Paris Agreement needs credible and transparent forest accounting and EU leaders are about to make a decision that could set the standard.   Including policy-driven increases in harvest in baselines means the atmospheric impacts of forest policies will be effectively hidden from the accounts (while generating GHG savings in other sectors). Basing forest accounting on a scientifically-objective approach would ensure the credibility of bioenergy accounting, consistency between EU targets and the IPCC 2°C trajectory, and compliance with the spirit of Paris Agreement. The wrong decision would increase the risks of climate change and undermine our ability to “make the planet great again”.

A response to Trump’s withdrawal from the Paris Agreement

The decision by President Trump to withdraw from the Paris Agreement on Climate Change puts the United States at odds with both science and global geopolitical norms.  The fundamentals of climate change remain unambiguous: greenhouse gas concentrations are increasing, they are increasing because of human action, the increase will cause warming, and that warming creates risks of extreme weather, food crises and sea level rise. That does not mean that scientists can predict all of the consequences of global warming, much work needs to be done, but the risks are both profound and clear. Nor do we know what the best solutions will be – there is need for a robust debate about the nature, fairness and efficacy of different decarbonisation policies and technologies as well as the balance of responsibility; the Paris Agreement, despite its faults with respect to obligation and enforcement, allowed great flexibility in that regard, which is why nearly every nation on Earth is a signatory.

Moreover, although climate change affects us all, it will affect the poorest and most vulnerable the most. They, despite being least responsible, bear the greatest risks and the greatest burdens. For the President of the world’s second largest carbon polluter to blatantly disregard such evidence and injustice, to refuse to even acknowledge the consequences of its actions and to disengage with this relatively modest and non-binding agreement puts it odds with the norms of global partnership and human rights. This abrogation of responsibility is particularly profound because President Trump has also withdrawn the United States from the Green Climate Fund, which helps the poorest of the world adapt to the climate change that his actions make more likely.

And to what end?  Other nations will now assume global leadership, politically, morally and technologically.  It will likely cost American businesses money, hinder innovation in one of the world’s most dynamic sectors, and ultimately cost jobs. It will likely undermine the United States’ global stature and diplomatic reach. It is hard to imagine a decision so blatantly motivated by self-interest while being so profoundly self-harming.

The crucial question now is how we respond.  China and the EU have stepped forward, increasing their voluntary commitments, repudiating President Trump’s decision and assuming the mantle of leadership.  Nations around the world are following suit, as are cities and states across the United States.  Businesses have re-stated their commitment to decarbonisation – ironically, the day before Trump’s decision, shareholders voted that Exxon develop plans compliant with the Paris Agreement’s targets.  In the UK, in the midst of a general election, parties from across the political spectrum have responded to Trump’s decision with reactions ranging from disappointment to outrage. The UK has always provided leadership in this arena, recognising that climate change is a non-partisan issue, and it is one of the few nations with a cross party Climate Change Act.  It is vital for both the planet and the UK that these initial comments are followed by bolder actions and stronger leadership.

Across the world and in the University of Bristol, we are frustrated with the symbolism of Trump’s actions, his speech’s misrepresentation of facts, and his decision’s potential to slow climate action.  But we also recognise that these actions will not stop climate action. The responses of local, national and international leaders, in politics, community groups and businesses, across sectors and across society show that no person, regardless of his position or his nation, can stop the energy revolution. It is too deeply embedded in our politics, economy and ambitions, borne of out of multiple necessities.

Here, in the University of Bristol Cabot Institute, we remain committed to this challenge.  Our University is committed to carbon neutrality, ethical and low-carbon procurement and divestment from fossil fuel-intensive businesses. We have foregrounded Sustainable Futures in our undergraduate teaching.  And in our research, we are investigating improved energy efficiency in everything from computer software, to our homes and our cities.  We are exploring how smart technology enables new forms of transport, community energy and individual action. We are converting nuclear waste into diamond batteries with 5000-year lifetimes, we are leading one of the projects under the Natural Environment Research Council’s Greenhouse Gas Reduction programme and we have just launched new initiatives in wind, tidal, solar and nuclear energy.

Our ambitions are at all scales, from the local to the global.  We continue to work with our Green Capital partners, with a focus on building an informed, diverse, inclusive and powerful movement to become a more sustainable city and region, exemplified by the Green and Black Ambassadors Initiative.  Globally, our projects have been exploring the impact of conflict, climate change and geological hazards on development and the environment; the potential for micro-grids to deliver electricity to isolated communities; new forms of parasite resistance for subsistence farmers; and how geothermal energy can be harnessed in Ethiopia.

This commitment to sustainability builds on five decades of research on our environmental challenges and how to manage them.  The Atmospheric Chemistry Research Group makes among the world’s most accurate measurements of atmospheric concentrations of greenhouse gases, and they have shown how rapidly these compounds are accumulating. They are committed to refining those measurements and the modelling methods that allow us to understand why global emissions change. The Bristol Initiative for the Dynamic Global Environment reconstructs past climates and uses those insights to better understand our future; recent projects are building global collaborations to explore the controls on Earth’s temperature and monsoons.  Our glaciologists study sea level rise; our hydrologists study floods and drought; our social scientists study the injustice of climate change and its impact on migration and conflict; and our vets and life scientists are exploring how to improve animal welfare and crop yields on a climate disrupted planet.

Our commitment includes appointing the best and the brightest at understanding these challenges, including Dr Dann Mitchell who joined the University in November.  As co-ordinator of the largest dedicated project in the world on the climate impacts of the Paris Agreement (www.happimip.org), he sums up the Cabot Institute’s collective commitment: “The news of Trump wanting to pull out is incredibly frustrating. Our results are already suggesting more extreme events, such as droughts and heat waves, and serious impacts on society, such as increased human and animal health issues, failures in global crop distributions and bleaching of our coral reefs. I am frustrated that Trump continues to ignore the scientific evidence that has been recognised by his global peers, but that will not dissuade us from doing all we can to understand climate risks… and prevent them.’

Environments without Borders

The effects of climate change vary hugely across political borders, and have wide-ranging impacts on different communities and environments. Climate policy responses must recognise this global interconnectedness, and integrate international cooperation with effective
local action. This is why global treaties such as the Paris Agreement are so important in the fight against climate change, but individual nations must also do their bit to achieve the objectives set out in the agreement. In Environments without Borders  (part of Research Without
Borders), a panel debate hosted by Bristol Doctoral College and the Cabot Institute on Wednesday 10th May, we will discuss some of these issues, using examples from our research on particular challenges facing our global ocean and water environments.

Rising Sea Levels

Many climate change impacts require a policy response that balances mitigation with adaptation. Mitigation, by reducing global greenhouse gas emissions to achieve a zero-carbon economy, can drastically reduce some of the worst effects of climate change. However, we are already committed to certain climate change impacts, and these will require humanity to adapt. Sea level rise is a prime example. Global sea level has already risen 20cm since 1900, and the rate of sea level rise is increasing. We know this trend will continue throughout the 21st century and beyond, but the question is, how much will sea level rise, and how fast?
Projections of global sea level rise by 2100 range from a further 30cm, assuming drastic mitigation action, to 1m or more in “business-as-usual” scenarios with increasing carbon emissions. Cutting carbon emissions can hugely reduce the number of people at risk of displacement by sea level rise globally, from up to 760 million in a scenario with 4°C of warming, down to 130 million if warming is limited to 2°C in line with the Paris Agreement. Mitigation is therefore essential if we want to avoid the worst effects, but adaptation is also necessary to ensure humanity is resilient to sea level rise that is already locked in.

Disappearing Islands

The South Pacific is home to some of the world’s states most vulnerable to climate change impacts. Sea-level rise threatens coastal erosion, the widespread displacement of people and the inundation of the lowest-lying islands in Tuvalu, Kiribati and the Marshall Islands, while oceanic warming and acidification threaten the livelihoods of many remote coastal communities. More intense tropical cyclones, Cyclone Pam in 2015 and Winston in 2016, have recently resulted in tragic losses of life and damages in excess of $449 million and $470 million respectively. The devastation facing Small Island Developing States in the region, when juxtaposed with their negligible contribution to global greenhouse gas emissions which is estimated at just 0.03%, serves to illustrate the need for the international community to urgently step up efforts to provide support. Enhanced financial assistance for adaptation is essential, however this must be accompanied by strengthened legal protection for communities, readily accessible compensation for loss and damage, capacity building and a strengthened role for civil society organisations giving voice to community needs and traditional knowledge in policy-making processes.

Invasive Aliens

Biodiversity in water environments can be adversely affected by invasive fish species, which originate from different sources, including marine ballast, fisheries improvements, and aquaculture. Invasive fish species can cause environmental concerns such as changes in the nutrients cycle, transmission of diseases, competence for resources, displacement and extinction of native species. Success in the establishment of invasive species depends on propagule size, physiology of the proper species, and current biotic and abiotic factors in the invaded system. Invasive species represent a global issue, and when combined with climate change their effects can be sharpened. Some limiting abiotic factors are expected to change as the climate changes, favouring new invasions and the spread of established invasive species to new ranges. Milder winters in northern latitude lakes, worldwide flooding and salinisation of coastal freshwater systems will provide suitable thermal conditions, new pathways for escape and dispersion, and the increase in dominance by invasive fish species adapted to brackish water systems. Deficient planning for future responses in water management can also result in favourable conditions for dispersion of undesirable aquatic organisms. For example, this is the case with the Nile tilapia, an invasive species in tropical ecosystems of southern Mexico and Tanzania, where flooding causes its dispersion but alternative management policies could improve the situation. More information see the Invasive Species Specialists Group.


Sustainable Resource Management

Against the backdrop of climate change, which will exacerbate the impact of human activities on natural resources, today’s environmental challenges require above all a strong and consistent commitment by national governments to better implement ambitious environmental policies that they previously adopted. However, traditional decision making approaches often are not equipped to ensure that precious resources are protected, if not enhanced. Sustainable management of natural resources is without doubt complex and creates conflicts between users that compete for access. For instance, there still seems to be too great a divide between the environmental and the business sector and these policy domains are as yet not fully integrated. Nonetheless, there are good examples of governments (and sub-national governments) that were successful in getting all key policy sectors on board when implementing difficult and ambitious environmental policies. For instance, the Scottish Government’s approach in implementing the Water Framework Directive demonstrates that with a strong political commitment, coupled with very proactive efforts in balancing the decision making towards more inclusive and cooperative policy processes, and with an intense and systematic use of evidence to back up policy proposals, it is possible to build trust between sectors and to act upon the barriers to implementation.

It’s clear that each of these challenges requires imminent action, but what are the right approaches, actors, and requirements to make meaningful progress? Whether you’re a member of the public, a policy maker, or someone working in the field, we invite you to join us at the Environments without Borders event on Wednesday 10 May for a lively and provocative debate about the challenges we face and how, collectively, we can spur action for change.

Climate negotiations: From Paris to Marrakech and… Trump?

A few weeks ago, Morocco hosted the Twenty-second Conference of the Parties on Climate Change (COP22), which meant to become the “COP for action”. One of the main challenges of this edition was setting the stage for the implementation of the Paris Agreement, adopted by the UNFCCC parties last December.

After the unexpected early entry into force of the Agreement, the COP22 sought to transform Paris discussions into reality and to develop concrete guidelines for achieving the 1.5°C goal. However, this call for climate action was disrupted on its second day by the outcome of the elections in the United States: someone who thinks climate change is a Chinese hoax was elected President of the Unites States.

When I arrived in Marrakech, I was not sure what to expect from the COP22 after that black Tuesday. The scenario was disappointing, but so predictable at the same time; besides the statements of countries such as China, Japan and the European Union ratifying their commitment to the fight against climate change (with or without the U.S. in the game), there was still an odd combination of uncertainty and sadness among delegates. These feelings were definitely projected onto the negotiations.

Broadly speaking, speculation overshadowed the final decisions of subsidiary bodies of the Convention and the governing body of the Paris Agreement (CMA).  They came out with generic final decisions, sometimes focused on procedural matters under the Paris Agreement and the rules of the Convention of Climate Change. In some other cases, they surprisingly postponed discussions to the next subsidiary bodies meetings in Bonn (May 2017) and, for topics such as the linkages between the Technology Mechanism and the Financial Mechanism to accelerate and enhance climate technology development and transfer, they agreed to bring it back again to the agenda at the twenty-fourth session in 2018.

But why? The answer is aggressively simple: Gaining time. By far, the U.S -one of the crucial players in the game of tackling Climate Change- has been leading a wide range of initiatives together with the European Union, China, Canada and Mexico, to name a few. It is understandable from an international perspective, that nations are anxious to know if, after this transition period, the U.S. will still be part of the team or abandon the game.

At COP22, the first press brief of the U.S. was delivered by Jonathan Pershing, U.S. Special Envoy on Climate Change. He stressed the importance of transitioning from negotiation to implementation and qualified as ‘immature’ speculating about the new administration and what actions they would take. But rumors of President elected Trump appointing a climate change destroyer as the head of the EPA were annoying many delegations in Marrakech.

The COP22 appeared to be a Conference for merely presenting initiatives agreed between the UNFCCC Parties, using the Paris Agreement goals as a guideline, rather than defining pathways for implementing the legal instrument itself. However, we should keep an eye on strategies such as the ‘2050 Pathways Platform’ presented by national and subnational entities as well as the private sector, to reach a deep decarbonisation towards the middle of the century; and the Global Partnership on Renewable Energy and Energy Efficiency launched by the least developed countries (LDCs) to speed up the clean energy transition.

In terms of climate finance, countries such as Canada, Denmark, the European Union, Germany, Italy, Japan, Korea, Switzerland and the United States announced a $23 million contribution to the Climate Technology Centre and Network (CTCN) of the UNFCCC to facilitate and accelerate climate change mitigation and adaptation measures in developing countries.

Patricia Espinosa, the Executive Secretary of the UNFCCC, remarked the importance of the deployment of clean and green technologies for the implementation of the Paris Agreement and the achievement of the Sustainable Development Goals (SGDs). She also stressed that “Finance will also be key if deployment is to happen at the speed and scale required”.

Although these initiatives can give us hope for the upcoming years, we should bear in mind that some pieces are still missing in the climate change puzzle.  Many countries are still deciding the roadmap for implementing their nationally determined contributions (NDC), whose achievements should be evaluated every five years; and the Ad Hoc Group of the Paris Agreement (APA) has not yet defined the rulebook for the implementation of the Agreement, nor the accountability rules to ensure a transparent and flexible process of monitoring and verification of those targets.

The international community agrees with the IPCC that climate change needs to be addressed now in order to achieve the well below 2 degrees aim. It is widely acknowledged that there is no time to lose, so why does time seem to have frozen for those in the frontlines of climate negotiations? Why they are still trapped in an endless loop of bickering?

During Education Day, Youth representatives raised their voices to say: We refuse to accept that this is over! And I am one of them. This is just the beginning of an era in which all sectors, from youth to the private sector, have to take the lead. We cannot base our decisions on childish statements from a democratically empowered billionaire and lose precious time. The clock is ticking, if we don’t take action now, there won’t be anything left to fight for in the near future.
