2014-2019 Hottest Six Years In Global Record; El Nino Pushed 2016 To #1; 2019 #2 All By Itself
The last six years have been the six hottest globally ever recorded by humans.
2014 had been the hottest year up to that point, until the record was shattered in 2015, and again in 2016 thanks to a monster El Niño event. El Niños bring hot water up to the ocean surface where it warms the temperature of the surface air that most directly influences and interests humanity. Next came 2017, the second-hottest year recorded by humans, but far and away the hottest that wasn’t influenced by an El Niño event. And then 2018, the fourth-hottest overall, but by far the hottest year on record that was cooled by a La Niña event.
And now 2019, warmed by a moderate El Niño event and as such not as hot as 2016 with its monster El Niño; but it was nevertheless the second-hottest year on record, and quite possibly the second-hottest in the history of human civilization.
As global warming has continued, so too has the volume of peer-reviewed reports and studies published by climate scientists documenting its accelerating impacts. Here are some of the most influential climate change research papers published in calendar 2019.
