Arctic Methane. Has 2020 triggered a tipping point?

The summer of 2020 saw record breaking heatwaves across the Arctic region resulting in the lowest ever recorded October sea ice levels. Those persistently warm temperatures also caused the thawing of permafrost and sediment on the seabed allowing the release of very high concentrations of methane - in some cases up to 400 times normal levels. So, have we now reached the long anticipated tipping point?
