Oops 😲. Arctic Emissions of Nitrous Oxide GHG a Dozen Times Worse Than Expected. Duh. Part 1 And 2
Paul Beckwith Climate ScientistPublished on Apr 20, 2019
Surprise... Nitrous oxide emissions from our rapidly warming north are up to 12-times higher than we previously thought, since thawing Arctic permafrost is a huge source.
The problem is:
1)the top 3 meters of permafrost contains 73 billion tons of nitrogen;
2)as it thaws microbial action releases bucket loads of N2O; and
3)N2O is a very powerful Greenhouse Gas, with a Global
Warming Potential about 300 times that of CO2 (lifetime in atmosphere of 114 years). In my last video I chatted about what this all means; here I show the science in plots and images from the paper.
