Description
5. Humans have already caused 1.07C of warming
The IPCC report estimates that global surface temperatures are now 1.07C warmer than they were between 1850-1900. Since 1970, global surface temperatures have risen faster than in any 50-year-period over the last 2,000 years and this has been particularly pronounced in recent years, with 2016-2020 being the hottest five-year period recorded since at least 1850.
And just in case there was any remaining doubt, the IPCC report makes it clear that the principal driver of these changes in temperature are down to human-released greenhouse gases.
