Rajendra Pachauri, the head of the U.N. Panel that shared the 2007 Nobel Peace Prize with former U.S. Vice President Al Gore, said he would look into the apparent temperature plateau so far this century.
"One would really have to see on the basis of some analysis what this really represents," he told Reuters, adding "are there natural factors compensating?" for increases in greenhouse gases from human activities.
He added that skeptics about a human role in climate change delighted in hints that temperatures might not be rising. "There are some people who would want to find every single excuse to say that this is all hogwash," he said.
[WMO's] Delju said temperatures would have to be flat for several more years before a lack of new record years became significant.
