Dance Class Reading

Regular readers of this blog are aware that on Saturday, I tend to post something eclectic. That's because most Saturdays I take my daughter to dance class, and I bring along National Geographic or Smithsonian to read (thanks, Beth). If I see something interesting, I tend to blog it. If my wife happens to take my daughter to class... well, you lose out.

Anyway, I went to class today and found a few things in the November National Geographic. The first is the item below on global warming.

OK -- it's not about global warming per se, but I couldn't help but thinking about the debate as I read the article.



I couldn't find really detailed data about where the photo was taken (although you can read more about this cave system here). But according to the caption, this cave was above water as recently as 18,000 years ago.

Take a look at that photo. It seems to me that sea level is at least a few dozen feet higher today than it was 18,000 years ago. Was that due to man-made global warming?
