US climate expert questions IPCC assessment process
The world's best and most authoritative climate science is currently being distilled for the fifth assessment report of the UN's Intergovernmental Panel on Climate Change (IPCC). The report, the first since the controversial 2007 IPCC report, is due for public release in September next year.
But one leading US climate scientist, Dr Kevin Trenberth, says he fears that the new report will be bland and overly cautious. He also says that 'mother nature' -- in the form of recent extreme weather events -- is challenging rampant climate denialism in America.
