Pathways after Paris

The Tyndall Centre for Climate Change Research has analysed for the UK’s Department of Business, Energy & Industrial Strategy some key research questions related to the implementation of the UN Paris Climate Agreement of 2015 and of the UK’s contribution. We have provided an assessment of some of the avoided global and regional impacts of achieving the Paris Goal, we have analysed new energy and CO2 pathways that limit climate change to 1.5oC and 2.0oC warming (the Paris Goal) and we have put these in the context of existing studies. We also examined some of the technical and societal innovations required to support such energy transformations.

ScienceBrief is a novel online platform that makes sense of scientific publications. It is written by experts from around the world to helps scientists select new scientific evidence and incorporate it into existing scientific assessments. ScienceBrief is a transparent, continuous, and rapid system for deciding if, and to what extent, new publications alter current knowledge. ScienceBrief shows the status and strength of scientific consensus in critical areas such as climate change and biodiversity, and highlights controversies and research needs. ScienceBrief combines the power of IT and the beauty of Science in support of society. 

ScienceBrief experts are being asked to assess three questions of existing and new peer-reviewed publications to inform the Paris Agreement. This emerging topic is analysed the scientific literature and its significance to these questions over the next 2 years.

1) What are the impacts of climate change of 1.5 compared to 2 degrees Celsius? The impacts of climate change will differ depending on the level and rate of warming. What differences are there for global warming of 2°C compared to 1.5°C? Can they be distinguished? What are the regional differences? What are the options for adaptation? What are the associated costs and implications for society and ecosystems?

2) What are the transformation pathways for limiting climate change to 1.5 compared to 2 degrees Celsius? Limiting climate change to 1.5°C compared to 2°C will require faster and deeper rates of global decarbonisation. What are the options, requirements and challenges by sector? What are the policies, actions and financial mechanisms for supporting transformation? What major technological developments are required and how feasible are they? What is the cost of the incremental effort of limiting warming to 2°C compared to 1.5°C? What are the co-benefits? What are the major uncertainties and how can they be reduced or mitigated?

3) What is the Global potential for removing greenhouse gases from the atmosphere? Emissions of CO2 and other greenhouse gases (GHG) need to be brought down to near zero to tackle climate change. Removing greenhouse gas from the atmosphere could help deliver on zero emissions, provided they are of sufficient scale and they do not interfere significantly with other societal priority such as food production. What is the potential for various methods proposed to remove GHG from the atmosphere? What is their current technological, demonstration, and deployment status? What are the potential implications for other societal needs, in particular the Sustainable Development Goals?
