Arctic Anguish

It appears that methane is now being rapidly released from the ice of the East Siberian coastal region (https://www.theguardian.com/science/2020/oct/27/sleeping-giant-arctic-methane-deposits-starting-to-release-scientists-find). This release of the potent 'greenhouse gas' in the Laptev sea (it is 80 times more potent than carbon dioxide) is very worrying. It may indicate that a tipping point has already been crossed, making it increasingly difficult to control climate change.
