A new report, published today by the Global Warming Policy Foundation*, examines how sensitive global climate is to greenhouse gases by examining evidence from observations and outputs from climate models. The report discusses scientific research referred to in the recently published Fifth Assessment report (AR5) of the Intergovernmental Panel on Climate Change (IPCC).
Dr Chris Huntingford, a climate modeller from the Centre for Ecology and Hydrology whose work is referenced in AR5, provided the following quotes in reaction to the report's publication:
“One persistent frustration is this belief that climate research is undertaken without any attention paid to the economic consequences of major emissions reductions. We are all acutely aware that to keep global warming constrained to two-degrees since pre-industrial times will most likely need a major alteration to energy policy. This is even for lower climate sensitivities. We definitely do worry about what reductions are possible and without causing financial damage.
“Socio-economists already collaborate with climate researchers, but this needs to be taken much further. If only those of incredibly sharp economic understanding and who contribute to the Global Warming Policy Foundation would, instead of continuously attacking efforts by the climate modelling community, collaborate with us. Much progress could then occur. They could tell us precisely what reductions in emissions they believe to be feasible, from which we can then calculate climate implications based on the remaining emissions. These calculations would include the factoring in of the, and we’ve always agreed, large, climate sensitivity uncertainty.”
Dr Huntingford's quote has also been published on the Science Media Centre website together with quotes from a number of other climate scientists.
