raw data point presented today by the NOAA and NASA shows that global temperatures strike a phonograph record gamey for the third straight year in 2016 . But while the El Niño weather system was cited as a chip in ingredient , the researchers say an overarch globular heating trend is indisputable .
As shown in thenew write up , the average global temperature across both solid ground and ocean for 2016 was 1.69 degrees F ( 0.94 degrees C ) above the 20th century norm of 57 degrees F ( 13.9 degrees C ) . Average temperatures last year were 0.07 degrees F ( 0.04 academic degree C ) higher than they were in 2015 . That makes it the hot year since the NOAA began keeping records since 1879 .
Disturbingly , this is now the fifth clock time that the temperature record has been shattered in the current 100 ( along with 2005 , 2010 , 2014 , and 2015 ) , and it ’s the fortieth successive yr feature an annual temperature above the twentieth C norm . All 16 years of the twenty-first hundred membership among the seventeen tender on platter , with 1998 being the eighth warmest .
A2016 temperature anomaly mapshows the entire globe in disquieting hues of redness . “ It was really global lovingness that we saw in 2016 , more so than what we observed in 2015 , ” note NOAA principal climate scientist Deke Arndt at a military press group discussion held originally today . His co-worker , Gavin Schmidt from NASA ’s Goddard Institute for Space Studies , said , “ the trend that we ’ve been seeing since the seventies are uphold and have n’t hesitate in any way . ”
The Arctic in peculiar took a real whacking , surprising even the scientists . temperature in Alaska , the Yukon , and part of easterly Siberia experienced modal temperature increases of 6 degree F ( 4 degrees C ) since pre - industrial times . “ No wonder the impacts of climate change are being felt [ in the Arctic ] first and first of all , ” said Schmidt . The warming of these northern region has resulted in increased coastal erosion , damage transportation infrastructure , melting permafrost , and botany moving into areas typically reserve for tundra . “ The warming of the Arctic has really been exceptional , ” he said .
The presence of a warming weather pattern known as El Niño pushed globular temperature above normal value in both 2015 and 2016 , but the researchers stress this was n’t the only reason .

The 1998 El Niño , for exercise , pushed globular temperatures to disc levels as well , but that ’s nothing compare to what was experienced in 2016 . There ’s something else at work — namely , human being - caused global warming . “ This [ latest ] El Niño might have contributed about a quarter or a third ” of the record in 2016 , said Arndt , adding that “ it ’s not a factor in the overall foresighted term style . ”
wait in front to 2017 , the cool trend cognise as La Niña could mean that a quaternary consecutive class of temperature phonograph recording wo n’t come about . Climate skeptics may use this as an opportunity to say that global warming is n’t literal , but “ people are savvy enough to see how transparent that is , ” said Arndt . The researchers predict that 2017 wo n’t be a disk - breaker , but they ’re confident it ’ll be a “ top five yr . ”
During the press conference , the NASA and NOAA researchers underline the importance of focusing on the big scene , and not just the recent three - year trend . “ We tend to focus on the previous year , but as far as what ’s crucial moving forrad , it ’s the long term style that ’s the most relevant , ” said Arndt .
The incoming Trump administration would be sassy to acknowledge this report . Troublingly , the President - elect , through console break up likeOklahoma Attorney General Scott PruittandExxonMobil CEO Rex Tillerson — both climate skeptics — hints at a very environment - hostile White House .
When asked how the fresh report might work US climate insurance policy over the next four years , Arndt sheepishly replied , “ We provide these assessments to the American people , and our charge is to trace the country of the climate . ” He turn down to elaborate any further .
