A novel approach to climate science has resulted in over 260,000 members of the public worldwide choosing to engage in a climate modelling project. By contributing resources that require their time and attention, they have become `citizen scientists'. The project has resulted in greater interest, understanding and engagement with climate science by participants; wider public discussion of climate science; and influence on policy and practice. Over 3000 people, including professionals in developing countries, have benefitted through education and training. The project has also advanced the development and awareness of `volunteer computing'.
International and national political negotiations and public debates about climate change mitigation policies can only progress with accurate and timely updates about the global carbon budget. Annual carbon updates have been supplied over many years, as a result of our work. The "Global Carbon Project" (GCP) has become the definitive source on carbon budgets for political and policy processes dealing with climate change mitigation and the GCP draws heavily on the School's work on the ocean carbon cycle, including ocean iron fertilisation, and its relevance to the contemporary global carbon budget. This is evidenced by its citation and influence on national (e.g. UK, Germany, Australia, USA, Sweden and Canada) and international (e.g. UN Framework Convention on Climate Change) deliberations.
This case study highlights the impact of LSE research on national and international carbon pricing policy. This includes a fundamental change in the way the UK government sets a carbon price for policy and project appraisal, and its approach to carbon trading in Europe. LSE work has also had impact beyond the UK, in particular on legislating — for the first time — policies to price carbon in strategically important countries across the world, including Australia, China, Mexico and South Korea.
Research at the University of Exeter on the links between the Amazon rainforest and climate change has influenced international climate policy, has directly assisted Brazilian environmental policymakers, and has received international media coverage. The underpinning research spans the vulnerability of the rainforest to anthropogenic climate change and the mechanisms behind the Amazonian droughts of 2005 and 2010. Impact has been achieved by stimulating public debate through the media, by contribution to science-into-policy documents produced by the World Bank and for the United Nations Framework Convention on Climate Change (UNFCCC), and by direct face-to-face interaction with UK and Brazilian policymakers.
Vincent Gauci and The Open University (OU) Ecosystems Research Group have demonstrated human influences over exchanges of carbon within vulnerable, temperate and tropical wetland ecosystems, which are the largest source of the powerful greenhouse gas methane to the atmosphere. The group's work showing that acid rain pollution suppresses methane emissions from wetlands has influenced policy in the UK, particularly peatland restoration, where the group has had direct interaction with users. The group's work on carbon balance resulting from deforestation, drainage and fires in the carbon-rich Bornean peat swamp has also informed IPCC methodologies for carbon balance calculations in its 2013 Wetlands Supplement.
We conducted research on the impact of land-use change that has resulted in international action to improve forest management. Our research demonstrated that clearing forests to grow crops for biofuels leads to large carbon emissions. In light of these findings, the UK Government amended its biofuel policy to include mandatory sustainability criteria. Leeds researchers co-established with a number of businesses the charity United Bank of Carbon, resulting in the investment of £1.5 million and the protection of 200,000 hectares of forest. Our research underpinned a forest-based climate mitigation scheme resulting in the investment of an additional £440k in forest protection.
Carbon dioxide sequestration is the process by which pressured CO2 is injected into a storage space within the Earth rather than released into the atmosphere. It is one of the major ways that carbon dioxide emissions can be controlled.
Research since 2004 by applied mathematicians at the University of Cambridge into the many different effects that might be encountered during this process has had considerable impact on government and industry groups in determining how the field is viewed and how it should and might be industrially developed. The work played a major role in the CO2CRC conferences and was subsequently reported to the Australian Government by the CO2CRC chair and organisers.
Information on the potential impacts of climate change across the world, and on the effects of policies designed to reduce emissions, is fundamental to inform the development of climate mitigation and adaptation policy. Research conducted at the Unit has been critical to the establishment of a target 80% cut in UK carbon emissions by 2050, as enforced by the Climate Change Act (2008), and provided an affirmation of the relevance of the 2f0b0C global mean temperature rise target central to national and international climate mitigation policy. Research into the global consequences of climate change, particularly for water resources and river flooding, has been used by the Department for Energy and Climate Change (DECC) to assess the impacts of un-mitigated climate change and the effects of different mitigation policy options.
Since 2005 the Agriculture and Environment Research Unit has undertaken an extensive programme of research related to mitigating the climate change impacts arising from agricultural land management policies and practices. The research findings that identified the impact on climate change of various policies, schemes and farming initiatives have been instrumental since 2008 in providing UK policy makers, farmers and their advisors with data and tools that helped to formulate improved climate change mitigation policies. They also contributed to the development of key guidance materials that supported the implementation of these policies on the farm.
University of Southampton research has been crucial in informing and stimulating worldwide debate on geoengineering — the possible large-scale intervention in the Earth's climate system in order to avoid dangerous climate change. Climate modellers at Southampton helped to reveal the potential extent of the fossil fuel "hangover" — the long-term damaging effects expected from anthropogenic CO2 emissions centuries or even millennia after they end. This work led Professor John Shepherd FRS to initiate and chair a Royal Society study, whose 2009 report, Geoengineering the Climate: Science, government and uncertainty, is the global benchmark document on geoengineering strategies, influencing UK and foreign government policy.
