Royal Society Bows (somewhat) To Climate Change Sceptics
Britain’s leading scientific institution has been forced to rewrite its guide to climate change and admit that there is greater uncertainty about future temperature increases than it had previously suggested.
The Royal Society is publishing a new document today after a rebellion by more than 40 of its fellows who questioned mankind’s contribution to rising temperatures.
"Climate change: a summary of the science" states that “some uncertainties are unlikely ever to be significantly reduced”. Unlike Climate change controversies, a simple guide — the document it replaces — it avoids making predictions about the impact of climate change and refrains from advising governments about how they should respond.
The new guide says: “The size of future temperature increases and other aspects of climate change, especially at the regional scale, are still subject to uncertainty.”
The Royal Society even appears to criticise scientists who have made predictions about heatwaves and rising sea levels. It now says: “There is little confidence in specific projections of future regional climate change, except at continental scales.”
It adds: “It is not possible to determine exactly how much the Earth will warm or exactly how the climate will change in the future. “There remains the possibility that hitherto unknown aspects of the climate and climate change could emerge and lead to significant modifications in our understanding.”
The working group that produced the new guide took advice from two Royal Society fellows who have links to the climate-sceptic think-tank founded by Lord Lawson of Blaby.
Professor Anthony Kelly and Sir Alan Rudge are members of the academic advisory council of the Global Warming Policy Foundation. They were among 43 fellows who signed a petition sent to Lord Rees, the society’s president, asking for its statement on climate change to be rewritten to take more account of questions raised by sceptics.
Professor John Pethica, the society’s vice-president and chairman of the working group that wrote the document, said the guide stated clearly that there was “strong evidence” that the warming of the Earth over the past half-century had been caused largely by human activity.
Meanwhile, the Government is planning an exercise to test how England and Wales would cope with severe flooding caused by climate change. Exercise Watermark will take place in March and test emergency services and communities on a range of scenarios that could occur.
