The deeper greenhouse gas emission cuts promised by U.S. President Joe Biden and other global leaders since last September have slightly improved the outlook for global warming. 

The world is on track by the end of this century to warm by 2.4 degrees Celsius above pre-industrial times, nonprofit Climate Action Tracker said in its May report. That’s an improvement from the group’s previous forecast of 2.6ºC, but still well above the 1.5ºC of warming that countries agreed to strive for when they signed the Paris Agreement in 2015.
