Large amounts of the greenhouse gas methane have been bubbling up to the surface of the Arctic ocean.
A Russian research team that has been surveying the region for two decades was startled to learn of the scale of the methane release that could have an impact on global warming. It is thought that hundreds of millions of tonnes of the gas is trapped below the permafrost and there are great concerns over what will happen if it is ever released in to the atmosphere.
"Dramatic and unprecedented plumes of methane – a greenhouse gas 20 times more potent than carbon dioxide – have been seen bubbling to the surface of the Arctic Ocean by scientists undertaking an extensive survey of the region."
