Nasa’s Goddard Institute for Space Studies claimed its analysis of world temperatures showed ‘2014 was the warmest year on record’
But it emerged that GISS’s analysis is subject to a margin of error
Nasa admits this means it is far from certain that 2014 set a record at all
The Nasa climate scientists who claimed 2014 set a new record for global warmth last night admitted they were only 38 per cent sure this was true.
Yet the Nasa press release failed to mention this, as well as the fact that the alleged ‘record’ amounted to an increase over 2010, the previous ‘warmest year’, of just two-hundredths of a degree – or 0.02C. The margin of error is said by scientists to be approximately 0.1C – several times as much.
As a result, GISS’s director Gavin Schmidt has now admitted Nasa thinks the likelihood that 2014 was the warmest year since 1880 is just 38 per cent. However, when asked by this newspaper whether he regretted that the news release did not mention this, he did not respond.
