Video: Earth to warm 2 degrees Celsius by the end of this century
August 2, 2017
By the end of the century, the global temperature is likely to rise more than 2 degrees Celsius, or 3.6 degrees Fahrenheit.
This rise in temperature is the ominous conclusion reached by two different studies using entirely different methods published in the journal Nature Climate Change on Monday.
One study used statistical analysis to show that there is a 95% chance that Earth will warm more than 2 degrees at century's end, and a 1% chance that it's below 1.5 C.
"The likely range of global temperature increase is 2.0-4.9 [degrees Celsius] and our median forecast is 3.2 C," said Adrian Raftery, author of the first study. "Our model is based on data which already show the effect of existing emission mitigation policies. Achieving the goal of less than 1.5 C warming will require carbon intensity to decline much faster than in the recent past."
