AS wrote to weigh in on something I said in the Aug. 5 issue.

I was wondering why we’re being told that, because of global warming and the melting of polar ice, there will be a dramatic rise in ocean water levels. It didn’t make sense to me. After all, the level of water in a glass doesn’t rise when the ice melts.

AS pointed out that when water heats, it expands. “Okay,” I thought. “That’s true. But could that tiny bit of expansion be enough to explain the entire ocean rising by inches, as has been predicted?” I had no answer to that, so I had to look it up. And I found a good explanation for the water glass phenomenon and the melting glacier phenomenon. It’s pretty interesting! Click here.
