NERC research on 1.5 degrees global warming provides timely evidence to inform policy

NERC reported this week on its research programme in partnership with the Department for Business, Energy and Industrial Strategy.

The 'Understanding the Pathways to & Impacts of a 1.5°C Rise in Global Temperature' research aimed to advance understanding of the research needs and provide timely evidence to inform policy following the introduction of the Paris agreement, when 195 countries committed to limit carbon emissions to keep global temperature rises under 2°C.

Professor David Wallom and Dr Sarah Sparrow contributed to the research in the project 'Quantifying the cumulative carbon emissions consistent with a 1.5°C global warming' (lead academic Professor Friedlingstein, University of Exeter). The project investigated sources of potential biases in models used to estimate current warming and the CO2 emissions remaining before we would reach 1.5C, in order to provide a robust assessment of the maximum amount of CO2 humankind could potentially emit in the future while limiting global warming to this level.

The project has shown that the remaining carbon budget is likely to be significantly more than assessed at the time of the IPCC 5th report, finding that the remaining carbon budget (200 gigatonnes of carbon) is equivalent to less than 20 years of emissions at current levels.

Research from the NERC programme has been cited in the Intergovernmental Panel on Climate Change (IPCC) special report on 1.5°C warming, published internationally on 8 October 2018, and launched in the UK as part of Green Great Britain Week.
