U.S. officials stressed that the El Niño pattern alone does not account of the year’s record warmth. “The interesting thing is that 2015 did not start with an El Niño,” Schmidt said. “It was warm right from the beginning.”
Because a strong El Niño still is in place, “2016 is expected to be an exceptionally warm year, and perhaps even another record,” Schmidt said.
The release of the 2015 temperature data prompted statements from leading Democratic presidential candidates Hillary Clinton and Bernie Sanders. Clinton, in a Twitter posting, said, “Climate change is real. It’s hurting our planet and our people. We can’t afford a president who ignores the science.”
There was no immediate comments from the major GOP contenders, several of whom have been openly skeptical of the mainstream scientific view that human activity is causing the planet to warm. Front-runner Donald Trump has dismissed climate change as a hoax.
According to the NOAA analaysis on Wednesday, every month in 2015 broke previous temperature records except for two: January and April. NOAA also announced Wednesday that for December, the “temperature departure from average was also the highest departure among all months in the historical record and the first time a monthly departure has reached 2°F.”
From a climate policy perspective, the warmth of 2015 is also highly significant. Global leaders in Paris agreed in December that the planet should not be allowed to warm 2 degrees Celsius above pre-industrial temperatures — and ideally, warming should be limited to 1.5 degrees Celsius if possible.
