Two headlines in USA Today and Reuters last week were very sobering: “Study: Global temperatures could rise 5 degrees by 2050,” and, even worse, “Global warming close to becoming irreversible.”

It’s not that I was surprised. I have known for years how urgent things are as far as our heated-up climate. Since I decided in 2003 that I needed to do more personally on this overarching survival issue, the world has seen a dramatic rise in the number and intensity of weather disasters, just as predicted by climate scientists years ago, though they’ve come sooner than most scientists expected.
