The data send a ‘stark’ message to the nations tasked with increasing action at the Cop26 climate summit, UN meteorology chief says
Levels of climate-heating gases in the atmosphere hit record levels in 2020, despite coronavirus-related lockdowns, the UN’s World Meteorological Organization has announced.
The concentration of carbon dioxide, the most important greenhouse gas, is now 50% higher than before the Industrial Revolution sparked the mass burning of fossil fuels. Methane levels have more than doubled since 1750. All key greenhouse gases (GHG) rose faster in 2020 than the average for the previous decade and this trend has continued in 2021, the WMO report found.
