Atmospheric levels of all three greenhouse gases hit record high


We have had more than 30 years to develop better energy sources, and chose not to.

Atmospheric levels of all three greenhouse gases have reached record highs, according to a study by the World Meteorological Organization, which scientists say means the world is “heading in the wrong direction”.

The WMO found there was the biggest year-on-year jump in methane concentrations in 2020 and 2021 since systematic measurements began almost 40 years ago.

Now the theory is that the methane rise could be caused by activities of microbes in wetlands, rice paddies and the guts of ruminants. Rising temperatures have caused the ideal conditions for microbial methane production, as they enjoy warm, damp areas.m

[Could one of the causes of the increase in methane be the melting of methane clathrates due to warming oceans.]


However, even if they act rapidly to stop the damage, much of it is already baked in. As long as emissions continue, global temperature will continue to rise. Given the long life of CO2, the temperature level observed will persist for decades, even if emissions are reduced swiftly to net zero.
