Earth’s thermostat reveals a brand new record: 2016 was the warmest year since record-keeping began in 1880. Spurred by global climate change and warmth from a monster, the worldwide average surface temperature last year was 0.94 degrees astronomer (1.69 degrees Fahrenheit) more than the twentieth century average of 13.9° C (57° F). This slightly edges out the previous titleholder, 2015, by 0.04 degrees C (SN: 2/20/16, p. 13). Eight months throughout 2016 set new incomparable highs, as well as July that was Earth’s warmest month on record, scientists from the National Oceanic and region Administration and National Aeronautics and Space Administration rumored Jan 18, 2017.
This is solely the second time that the annual temperature record has been broken 3 years in an exceedingly row, Deke Arndt, chief of the observance branch of NOAA’s National Centers for Environmental data in town, N.C., same in an exceedingly conference. The previous trio — 1939 through 1941 — don’t rank among the highest thirty warmest years on record, he noted. Last year’s heat helped set alternative records also. Jan17 as an example, world ocean ice extent is at its paltriest purpose in probably thousands of years, in keeping with knowledge from the National Snow and Ice knowledge Center and ocean ice reconstructions.
Greenhouse gases discharged by human activities like fuel burning have cranked Earth’s thermostat over the previous few decades by stable gear heat that may otherwise escape into area. All sixteen years of the 21stcentury rank among the 17 warmest on record. “Humankind’s fuel habit isn’t exclusively guilty for 2016’s sweltry heat” says Kevin Trenberth, a climate man of science at the National Center for region analysis in Boulder, Colo.

Trenberth predicts. “The temperature record is like increasing a steps, and currently with 2015 and 2016, we’ve appeared to go up another step,” he also says  “We’ll perhaps oscillate around this higher level for a number of  years, however I don’t suppose we’ll ever return to the values we’ve seen in previous years.”
