The study, published in Scientific Reports, is the first to show methane is released from glaciers on such a large scale. Methane is a greenhouse gas far more potent than carbon dioxide. It is becoming of increasing concern because of its potential to contribute to climate change. In Arctic regions, methane is locked up in permafrost. As global temperatures increase, the soil thaws and methane is released, contributing to further warming. If this volcano and glacier is representative of other similar systems, it could mean masses of previously unaccounted methane are being released into the atmosphere. - Newsweek -
