Katey Walter Anthony is a professor who studies permafrost and methane at the University of Alaska. She scouts the countryside looking for the thousands of new lakes that are forming as the permafrost melts. From some of them, methane bubbles are entering the atmosphere, and she can set fire to them to make sure they are really methane. No one can be sure whether these portend grave risks to our own survival but it is clear that they have serious implications for global warming, though perhaps less than the possible disasters from fossil fuels.

We produce several one-hour-long Zoom conversations each week about various aspects of six issues we address. You can watch them live and send a question to the speakers or watch the edited version later here or on our Youtube channel.
