Duality in climate science
A commentary published in Nature Geoscience (online Oct. 2015)
Brief Abstract:
The commentary demonstrates the endemic bias prevalent amongst many of those developing emission scenarios to severely underplay the scale of the 2°C mitigation challenge. In several important respects the modelling community is self-censoring its research to conform to the dominant political and economic paradigm. Moreover, there is a widespread reluctance of many within the climate change community to speak out against unsupported assertions that an evolution of ‘business as usual’ is compatible with the IPCC’s 2°C carbon budgets. With specific reference to energy, this analysis concludes that even a slim chance of “keeping below” a 2°C rise, now demands a revolution in how we both consume and produce energy. Such a rapid and deep transition will have profound implications for the framing of contemporary society and is far removed from the rhetoric of green growth that increasingly dominates the climate change agenda.

On the duality of climate scientists:
… how integrated assessment models are hard-wired to deliver politically palatable outcomes
The value of science is undermined when we adopt questionable assumptions and fine-tune our analysis to conform to dominant political and economic sensibilities. The pervasive inclusion of speculative negative emission technologies to deliver politically palatable 2°C mitigation is but one such example. Society needs scientists to make transparent and reasoned assumptions, however uncomfortable the subsequent conclusions may be for the politics of the day.
