Jaw-Dropping Methane Levels up to 9 times Global Average Measured Recently Over Arctic Shelf: 2 of 2

Published on Oct 10, 2019
In our world of satellite data, computer models, and simulations, on-the-ground (on-the-ocean in this case!) field work is invaluable. UK’s Peter Wadham’s is the sea-ice expert and Russia’s Igor Semiletov is the Arctic methane expert, both exploring via numerous expeditions over many decades. Recent data from an expedition led by the latter report report stunning methane levels 9x higher than global averages. This is very serious, given methane’s global warming potential of 34x, 86x, and over 150x with timescales of 100 years, 20 years, and a few years, respectively.
