The gang discusses two papers that look at the effects of climate change on cold adapted species, as well as the possibility of evolutionary rescue as a means of preserving this biodiversity. Also, it gives them all a great excuse to just talk about weasels (and somehow badgers as well). Meanwhile, Curt invents alternative Nintendo canon, James wants a giant robot spider body, and Amanda invents personalities for pictures of weasels.
Up-Goer Five (Amanda Edition):
Today our friends talk about how when things get warm it is bad for lots of things that live. Our friends look at long things with hair that need to eat more. These long things with hair that need to eat more are either dark or white. They are white when it is cold and dark when it is warm and that helps them hide. But with things turning more warm every year, it is getting too different for these long things with hair that need to eat more. Now sometimes they change from dark to white when it is still too warm, or, more often, they are still white when it is time to be dark. One paper says that this means the long things with hair that need to eat more get eaten more often by big things with big teeth and pointed fingers and hair, or by big things that fly that have no teeth and pointed fingers and no hair. The other paper says that maybe we need to look at some parts of the world that no one cares about and save them for animals, because these are places where the long things with hair that need to eat more that change color from dark to white and back to dark may be able to live.
