STOCKHOLM—A climate research group says carbon emissions cuts pledged by governments could rein in global warming by up to one degree Celsius by 2100.
On the Oct. 1 deadline for submitting pledges for a U.N. climate pact, the Climate Action Tracker group said if fully implemented, the emissions targets would result in 2.7 degrees Celsius of warming compared to pre-industrial times. Without those cuts, the group calculated that there would be an additional 0.5-1.1 degrees Celsius of warming.
Currently, temperatures are about 1.8 C warmer than in pre-industrial times.
A separate analysis this week by the U.S.-based Climate Interactive group projected 3.5 degrees Celsius of warming based on the current pledges.
All major carbon polluters except India submitted targets by the deadline.
