September 2016 was the warmest September on record in 136 years according to NASA and while the US space agency has refrained from providing the reasons behind the high temperatures, it won’t be too far-fetched to assume that the global warming and climate change are to blame for this.
While September 2016 was the warmest, it achieved that status by a razor-thin margin of 0.004 degrees Celsius over the previous warmest September in 2014. Statistically the two months are in a tie as far as temperatures go. If we look at the mean September temperature for three decades from 1951-1980, September 2016 was 0.91 degrees Celsius warmer.
NASA’s Goddard Institute for Space Studies (GISS) in New York performs the monthly analysis of the global temperatures and according to the GISS, record temperatures in September 2016 means that 11 of the past 12 consecutive months have now set new monthly high-temperature records. Updates to the input data have meant that June 2016, previously reported to have been the warmest June on record, is, in GISS’s updated analysis, the third warmest June behind 2015 and 1998 after receiving additional temperature readings from Antarctica. The late reports lowered the June 2016 anomaly by 0.05 degrees Celsius to 0.75.
NASA tracks temperature and sea ice as part of its effort to understand the Earth as a system and to understand how Earth is changing. In addition to maintaining 19 Earth-observing space missions, NASA also sends researchers around the globe to investigate different facets of the planet at closer range. NASA researchers are working across the Arctic to better understand both the processes driving increased sea ice melt and the impacts of rising temperatures on Arctic ecosystems.
The monthly analysis by the GISS team is assembled from publicly available data acquired by about 6,300 meteorological stations around the world, ship- and buoy-based instruments measuring sea surface temperature, and Antarctic research stations.
