u of m profs
a professor from the university of michigan gave a talk on climate change. he regurgitated a lot of the same stuff you're sick of seeing by now. he's not really a climate scientist. despite the title of his talk. he grew up in alaska and studies mercury pollution in polar bears. which is not due to global warming. but rather to burning coal. polar bears hunt seals on the ice and birth their cubs on land. climate change is making the swim between the two longer and longer. this double whammy might reduce the polar bear habitat to the zoo.
