I saw a science show last night about a huge glacier in Greenland that is moving faster than it should. Glaciers typically move about a foot a day, but this one is moving about 113 feet a day, and steadily speeding up, even in the winter when it shouldn't really be moving at all. It turns out that this glacier has been melting so much, due to global warming, that the water it produces has been making its way down a hole in the middle of it, all the way to the bottom. You would think that water travelling through miles of ice would freeze back up before getting all the way through, but there's so much of it that the sheer pressure has forced it all the way down underneath the glacier, where it creates a little pool on which the entire glacier is now floating. So it's moving across the land and dumping itself into the ocean at a much faster rate than anyone thought possible, and this particular glacier accounts for 4% of all the sea level increases worldwide. Meanwhile, the exact same thing is happening with other glaciers all over the place.
We went to yoga last night, which was great, but I think I kind of overdid it. It's supposed to make you feel good, but today my back and legs are a little bit aching. Guess I was thinking too much about the goal and not enough about enjoying the process. No gym for me today!

That's a really great lizard picture! Man I need photoshop.
He looks pretty good as a lizard, but not cool enough... He's more like a sheep, I was thinking... Are you going to take on 'The Photo Challenge'? :D
