NASA Climate Scientists Are Only 38 Per Cent Sure About 2014 as Hottest Year

The NASA climate scientists who claimed 2014 was the hottest year on record, now reportedly say that the likelihood that 2014 was the warmest year since 1880 is only 38 per cent sure.

As per the reports by Daily Mail, it is now emerging that the analysis by NASA’s Goddard Institute for Space Studies (GISS) is subject to a margin of error. This means the space agency is far from certain that 2014 set a record at all.

NASA and the US National Oceanic and Atmospheric Administration (NOAA) released a preliminary analysis claiming that 2014 was the warmest since record-keeping began in 1880, a week ago.

The findings were based on globally averaged temperature data collected from a network of land and water surface sensors. The news made headlines the world over.

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’. However, as per Daily Mail, GISS’s director Gavin Schmidt has admitted the likelihood that 2014 was the warmest year since 1880 is just 38 percent.

“The NASA press release failed to mention that the alleged ‘record’ amounted to an increase over 2010, the previous ‘warmest year’, of just two-hundredths of a degree – or 0.02C. Themargin of error is said by scientists to be approximately 0.1C – several times as much,” the report added.

Another analysis, from the Berkeley Earth Surface Temperature (BEST) project concluded that if 2014 was a record year, it was by an even tinier amount.

“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,” the BEST report said. (IANS)
