Methane Antarctica
mardi 22 août 2017 à 02:00There is a large reservoir of methane in the ground under the Antarctic ice sheet. If the ice melts, that methane will be released, which would cause further global heating.
Methane lasts only a few decades in the atmosphere. If the ice melts over a period of 200 years, only a small part of the methane will be in the air at any one time.
