Future temperature changes
We have already observed global warming over the last several decades. Future temperatures are expected to change further. Climate models project the following key temperature-related changes.
Key global projections
Increases in average global temperatures are expected to be within the range of 0.5°F to 8.6°F by 2100, with a likely increase of at least 2.7°F for all scenarios except the one representing the most aggressive mitigation of greenhouse gas emissions.[2]
Except under the most aggressive mitigation scenario studied, global average temperature is expected to warm at least twice as much in the next 100 years as it has during the last 100 years.[2]
Ground-level air temperatures are expected to continue to warm more rapidly over land than oceans.[2]
Some parts of the world are projected to see larger temperature increases than the global average.[2]
