Feeling the heat? Data confirms that global temperatures in the first half of the year were the hottest since records began more than a century ago.
Scientists have also released what they described as the "best evidence yet" of rising long-term temperatures. The report collates 11 different indicators – from air and sea temperatures to melting ice – dating back to between 1850 and the 1970s. Each is based on three to seven data sets.
"When you follow those decade-to-decade trends then you see clearly and unmistakably signs of a warming world," said Peter Stott, head of climate modeling at the UK Met Office.
"That's a very remarkable result, that all those data sets agree," he added. "It's the clearest evidence in one place from a range of different indices."
