Warmist crooks backpedal
Now that they have got the lie splashed worldwide they can afford to do that
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.
In a press release on Friday, Nasa’s Goddard Institute for Space Studies (GISS) claimed its analysis of world temperatures showed ‘2014 was the warmest year on record’.
The claim made headlines around the world, but yesterday it emerged that GISS’s analysis – based on readings from more than 3,000 measuring stations worldwide – is subject to a margin of error. Nasa admits this means it is far from certain that 2014 set a record at all.
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.
Scientists disagree over its significance, but there is little doubt that the rapid warming of the 1980s and early 1990s has slowed – although greenhouse gas emissions have surged.
Bob Ward, of the Grantham Institute on Climate Change, said the new figures showed the notion that global warming had ‘stopped’ was a ‘myth’, although it had ‘temporarily slowed’. Since 1951, he added, the long-term trend was for warming of 0.12C per decade, and in his view, it would ‘pick up again unabated’ if emissions continued to rise.
However, if the long-term rate is 0.12C per decade, this would mean the world would be 1C or so warmer by the end of the century, not 4C-5C as some have claimed.
Climate sceptics insisted that the new figures showed the warming ‘pause’ had continued. Dr David Whitehouse, of the Global Warming Policy Forum, said ‘there has been no statistically significant warming trend since 1997’ – because the entire increase over this period was smaller than the error margin.
