Earth breaks heat record
It’s official: 2016 was the hottest year on record since scientists began tracking Earth’s temperature more than 100 years ago, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration.
The 1.69-degree jump over the 20th century average, according to NOAA, marks the third year in a row that global temperatures have reached record-shattering levels. The National Aeronautics and Space Administration added that the global average temperature for 2016 was 1.78 degrees higher than a baseline period between 1951 and 1980.
Both agencies noted that Earth’s average global temperature — which NOAA pegged at 57 degrees — was higher in 2016 than in any year since scientists began tracking it in 1880.
“For the first time in recorded history, we have now had three consecutive record-warm years,” said Michael Mann, a climate scientist at Pennsylvania State University who was not involved in the findings.
“The likelihood of this having happened in the absence of human-caused global warming is minimal.”
