I still think it's a cool 404 page...
BTW, before devoting my life to the mysteries of the Unix operating system I was an environmental geologist. And although I don't have much time to read 'em I still get a stack of scientific journals and it seems that the peer-review scientific community does indeed agree that global warming is real.
Now, the real question: Is global warming a man-made phenomenon or a natural climate change? The jury is still out but seems to be leaning toward the man-made part from what I can gather.
Either way, it's really messing with some folks. Philip wrote about some of this during his trip to Alaska this past summer. Other folks in the Pacific are find their islands disappearing as sea-level rises and they're more exposed to storm-surge. Glaciers all over the world are receding.
Of course, by the time we really know if global warming is "real" or not (and its real cause) it'll be too late to do much about it.
Now, about bats: I studied a lot of Karst topography and limestone petrology in school. I spent lots of time underground mapping caves and spent one summer as a cave guide at a commercial cave. Maybe these studies had different bats, but those I observed didn't behave like this.
Most bats roosted in the same general area but not necessarily the same perch every night. And they knew if something changed and didn't attempt to land if the surface didn't have an appropriately rough surface to attach to (we tested this indirectly). Sometimes they'd miss and fall but quickly recover. Interesting stuff, but at the time I didn't pay much attention to the biology and instead focused on the geologic aspects. I do know big steaming piles of bat guano were a pain to crawl through....
