<b>World's top climate scientists told to 'cover up' the fact that the Earth's temperature hasn't risen for the last 15 years</b> PUBLISHED: 20:40, 19 September 2013 | UPDATED: 20:41, 19 September 2013 Scientists working on the most authoritative study on climate change were urged to cover up the fact that the worldâs temperature hasnât risen for the last 15 years, it is claimed. A leaked copy of a United Nations report, compiled by hundreds of scientists, shows politicians in Belgium, Germany, Hungary and the United States raised concerns about the final draft. Published next week, it is expected to address the fact that 1998 was the hottest year on record and world temperatures have not yet exceeded it, which scientists have so far struggled to explain. The report is the result of six yearsâ work by UNâs Intergovernmental Panel on Climate Change (IPCC), which is seen as the world authority on the extent of climate change and what is causing it. But leaked documents seen by the Associated Press, yesterday revealed deep concerns among politicians about a lack of global warming over the past few years. Germany called for the references to the slowdown in warming to be deleted. The United States delegation even weighed in, urging the authors of the report to explain away the lack of warming using the âleading hypothesisâ among scientists that the lower warming is down to more heat being absorbed by the ocean â which has got hotter. Scientists are under pressure to explain why the warming has not exceeded 1998 levels although the decade 2000-2010 was the hottest on record.
