- Scientists have discovered that the Arctic glaciers are leaking significant amounts of methane into the atmosphere.
- Methane concentrations in the melt river were found to be up to 800 times higher than the atmospheric equilibrium level.
- The methane that was being released was not produced by the microbial activity beneath the ice.
- Rather it came from thermogenic sources — methane that had been trapped in the region’s ancient geological formations for millions of years.
- Methane is one of the main drivers of climate change, responsible for 30 per cent of the warming since preindustrial times, second only to carbon dioxide.
- Over 20 years, methane is 80 times more potent at warming than carbon dioxide.
