Here’s a piece of seriously distressing news on the climate change front:
A University of Alaska-Fairbanks team on expedition in the Canadian Arctic was “astounded” to find that permafrost (you know, that stuff that has been frozen solid for thousands of years) was thawing 70 years earlier that predicted.
When permafrost melts, it releases methane, which is a particularly potent greenhouse gas. When that happens, it accelerates global warming which, in turn accelerates the melting of permafrost, which in turn…. You get the idea.
Climate scientists call it a “feedback loop.” A more apt description is a “death spiral”.
