Melting Arctic Glaciers are Releasing Ancient Methane, Study Finds
Rivers flowing from melting glaciers in Svalbard are carrying ancient methane out of rocks beneath the ice, according to new research. The discovery reveals a natural climate feedback that could become more important as the Arctic warms and glaciers continue to shrink. Methane is a powerful greenhouse gas. Although the amount identified in the study […]
The meltwater flows from 19 glaciers examined on Svalbard were all oversaturated with methane, partly around 425 times the atmospheric equilibrium. Isotope measurements show that the gas mainly comes from old, organically rich rock. Particularly much methane transport glaciers when slanting-rich underground meets a thawed, water-bearing glacier bed. Tromsø (Norway). Among glaciers methane can come from various sources [...] The article Melting g…
Meltwater from the Spitsbergen glaciers contains methane that has been trapped in rocks under the ice for millions of years. This powerful greenhouse gas can then reach the atmosphere via glacial rivers. And as the Arctic continues to warm, emissions increase. This is the conclusion of a new study that collected 148 water samples from nineteen rivers flowing through glaciers [...] More science? Read the latest articles on Scientias.nl.
