Climate expert says he underestimated threat

Wed Apr 16, 2008 - LONDON (Reuters) - Climate change expert Nicholas Stern says he under-estimated the threat from global warming in a major report 18 months ago when he compared the economic risk to the Great Depression of the 1930s.

Latest climate science showed global emissions of planet-heating gases were rising faster and upsetting the climate more than previously thought, Stern said in a Reuters interview on Wednesday.

For example, evidence was growing that the planet's oceans -- an important "sink" -- were increasingly saturated and couldn't absorb as much as previously of the main greenhouse gas carbon dioxide (CO2), he said.

"Emissions are growing much faster than we'd thought, the absorptive capacity of the planet is less than we'd thought, the risks of greenhouse gases are potentially bigger than more cautious estimates, and the speed of climate change seems to be faster," he told Reuters at a conference in London.
