Current climate policies don’t go far enough

Greenhouse gas emissions need to fall almost immediately to put the world on a path to limiting warming to around 2.7 degrees Fahrenheit by 2100. Under nations’ current policies, warming would rise at about 5 degrees Fahrenheit by 2100.

1 The world’s nations generated 51 gigatons/year of greenhouse gases in 2016.
2 To limit warming to 2.7 degrees Fahrenheit by 2100, emissions would need to fall almost by half by 2030.
3 Current climate policies would lead to around a 5 degree Fahrenheit rise in global temperatures by 2100.
