A The Independent says that below the arctic’s icebergs and ice flows are millions of tons of greenhouse gases that are slowly bubbling to the surface as the arctic atmosphere warms, and the ice melts and allows room for it to rise. While this has been a theory for many years now, scientists have now witnessed “methane chimneys” where the permafrost has melted. Since methane is a greenhouse gas 20 times more powerful than carbon dioxide, this should cause concern about how quickly the icebergs are melting. Scientists believe that this methane release can be linked with the rapid increase of arctic temperature in the past years, and can even be traced back to historical extinction events. Although this doesn’t entirely explain our climate crisis, it certainly appears to be playing a factor – keep it in mind.
