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. Another analysis, from the Berkeley Earth Surface Temperature (BEST) project, drawn from ten times as many measuring stations as GISS, concluded that if 2014 was a record year, it was by an even tinier amount.Its report said: ‘Numerically, our best estimate for the global temperature of 2014 puts it slightly above (by 0.01C) that of the next warmest year (2010) but by much less than the margin of uncertainty.
And here's the kicker:
‘Therefore it is impossible to conclude from our analysis which of 2014, 2010, or 2005 was actually the warmest year… the Earth’s average temperature for the past decade has changed very little.’
The earth's average temperature has changed very little over the last decade. When skeptics say this they're compared to Holocaust Deniers.

After reviewing multiple presentations by Nobel prize-winning scientists, this claim of the hottest year on record is just another 'inaccurate' statement by political fools. What about the 1930's record temperatures? When you make a claim that isn't backed up by the accuracy of the measurements, you are a political fool. Just because you fill a government position doesn't make you more intelligent or more accurate than real scientists. Remember, political science is the art of disinformation!!!!
