What is the 1.5 C threshold?

The 2015 Paris Agreement commits countries to limit the global average temperature rise to well below 2°C above pre-industrial levels, and to aim for 1.5°C. Scientists have said crossing the 1.5°C threshold risks unleashing far more severe climate change effects on people, wildlife and ecosystems.

What does 1.5 degrees of warming mean?

At 1.5 degrees Celsius, it’s likely that 70 to 90% of coral reefs will die off worldwide. At 2 degrees Celsius of warming, 99% are lost. “If we delay even a year or two more, we really are going down a pathway where there will be no return,” Hoegh-Guldberg says.
