Though scientists have warned for many years in regards to the threat to humanity and Earth posed by unfettered burning of fossil fuels, in 2019 — set to be the second hottest yr in historical past — their message appears to have lastly hit dwelling.
The 2015 Paris settlement noticed nations decide to limiting world warming to 2 levels Celsius (2.7 Fahrenheit) above pre-industrial ranges as a approach of curbing the worst impacts of world warming.
A safer cap of 1.5C was included as a aim for nations to work in the direction of.
With Earth having already warmed by 1C, the United Nations Intergovernmental Panel on Local weather Change (IPCC) dropped a bombshell late final yr.
Its landmark report in October 2018 laid the groundwork for the string of local weather shockwaves that rumbled all through 2019: The world is approach off target for 1.5C, and the distinction between 1.5C and 2C might be catastrophic.
“The message from scientists was that every half-degree counts,” mentioned Amy Dahan, a science historian specialising in local weather at France’s Nationwide Centre for Scientific Analysis.
It was a message heard around the globe.
For Corinne Le Quere, president of France’s Excessive Fee for Local weather Change and member of Britain’s Committee on Local weather Change, 2019 was “one thing new”.
