On November 11, the CBS program “Sunday Morning” had a segment on global warming that is worth watching. It is fairly short–about five minutes. It features four different experts on climate change all of whom agree that (1) global warming is real, (2) it is accelerated by human activities, and (3) we can do something about it if we unite to do so. It’s a mainstream television show broadcast into millions of homes, which I found heartening. Here is the link.
