Earth is on track for average warming of 2.7 degrees Celsius by 2100, higher than the UN target, said an analysis Thursday of country pledges for curbing climate-altering greenhouse gas emissions.
While exceeding the UN’s goal of limiting warming to 2 C (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels, the number was an improvement on the three-degree forecast issued in September by the Climate Action Tracker, a tool developed by a group of research organisations.
