Almost every nation on Earth signed up to the goals of the Paris climate agreement in 2015. This pact aims to keep the rise in global temperatures well below 2C this century and to pursue efforts to keep it under 1.5C.

The new IPCC report says that under all the emissions scenarios considered by the scientists, both temperature rise targets will be broken this century unless huge cuts in carbon take place.

IPCC report key points:

° Global surface temperature was 1.09C higher in the decade between 2011-2020 than between 1850-1900.
° The past five years have been the hottest on record since 1850
° The recent rate of sea level rise has nearly tripled compared with 1901-1971
° Human influence is "very likely" (90%) the main driver of the global retreat of glaciers since the 1990s and the decrease in Arctic sea-ice
° It is "virtually certain" that hot extremes including heatwaves have become more frequent and more intense since the 1950s, while cold events have become less frequent and less severe
