Top UK science advisor: Scientists need to acknowledge uncertainty about climate change

Scientists have exaggerated the impact of climate change and need to be more honest about how difficult it is to predict, the Government’s chief scientific adviser said today.

Professor John Beddington added that experts should be less hostile to sceptics who question man-made global warming.

And he condemned those who refuse to publish full report data, adding that public confidence in climate science would be boosted by greater honesty about its uncertainties.
