A new United Nations report finds that global plans to fight climate change will barely reduce future warming, mainly caused by the burning of fuels like gas, oil and coal.

The report says that the United States' withdrawal from the Paris Agreement counteracts much of the progress made in recent years. The latest climate plans reduce future warming by about three-tenths of a degree Celsius. However, the U.S. exit will add back a tenth of a degree. The planet is on track for 2.3 to 2.5 degrees Celsius (4.1 to 4.5 degrees Fahrenheit) of warming. Even rapid emission cuts may not prevent temperatures from reaching at least 1.7 degrees Celsius (3.1 degrees Fahrenheit) this century. 

The Trump administration policies, which range from rolling back environmental regulations to hindering green energy projects, will add back a tenth of a degree of warming, Tuesday's U.N. Environment Programme's Emissions Gap report says. 

Global average temperature increase is mainly caused by the release of greenhouse gases like carbon dioxide, which happens when fuels like oil, gas and coal are burned. So the plans that countries turn in must detail how, and how fast, they will cut emissions of such gases.  

Even super fast and deep cuts in emissions from coal, oil and natural gas will still more than likely mean global temperatures go up at least 1.7 degrees Celsius (3.1 degrees Fahrenheit) this century with efforts then to bring them back down, the report says. 

Ten years ago, before the Paris Agreement, the world was on a path to be about 4 degrees Celsius (7.2 degrees Fahrenheit) warmer.
