Honestly, going into Al's presentation (and I think I know him well enough to call him Al, assuming he will call me Betty), I thought listening to a wooden dude drone on about the weather getting nicer for an hour was going to be the most deadly-dull thing I'd ever done. I thought, "Oh, boy, I love being lectured about what a bad person I am for living and breathing and how we're all going to heck and there's nothing I can do. It brightens up my day!"
I was wrong. Al's presentation was funny, enlightening, and most of all moving. He presented raw data, pictures, and yet more data, and yet more pictures, all of which points to our world being irreversibly changed in the next several years, for the much, much worse. There is a vast and overwhelming amount of evidence for this, and it is cited for your perusal if you are skeptical. The social and economic fallout will be devastating to life as we know it. This isn't about us enjoying lovely sunshine year-round -- this is about hurricanes, plagues of insects, massive species die-offs, new diseases -- real armageddon stuff, folks.
Most scientific reports I've seen now agree that the Sahara desert was created by man, thousands of years ago. We did that. We had too many cattle, we overgrazed the land, it dried out and started a cycle that perpetuated itself and even accelerated. The giant sand trap in middle of Africa, visible from space, that has plunged that entire nation into poverty for thousands of years... that was our fault.
Let's learn from our mistakes. Just this once, when it matters most.
PS: Go see Snakes on a plane it's going to rock.
Update: The trailer is finally out.
