Dr. James Hansen is, of course, NASA’s lead atmospheric scientist.
No need for me to add anything.
A longer presentation is after the jump.

Great 5 min video. Question: I can’t find a particular link, but I’m sure I remember reading general skepticism about the possibility of a runaway greenhouse effect. Does anyone have any links to hand on this? My interweb googly skills are letting me down…
you are correct, there is skepticism on this point.
Don’t have a quick link available.
But runaway or not, 5, 8, or 10 degrees of warming will bring
unheard of catastrophes for human beings.
Indeed. A link from the Guardian today on desertification. A quote:
“Since the early 1980s, a quarter of the planet’s land has been despoiled and 1% a year continues to be lost… ‘The world is driven by city dwellers: political leaders are setting agendas to satisfy people who live in the cities, we therefore tend to perceive soil as just dust, or mud, or a dumping place. But if we don’t preserve that first 20cm of soil, where will we get our food and water from?’ “
Apols for the multiple posts, I always forget something. Just to offset the misery of the last post –

Only five minutes; the amazingly cheering take-home message = with some simple earth-works as a foundation, scrubland ended up not only producing food, but being moist enough to develop its own fungi. Hope is not lost!
great link.
I can do multiple uplifting posts with this.
Excellent – hit ’em with the Berkeley-approved misery-hope 1-2. Kapow!
From the same talk, here is is a 50 minute discussion after Hansen’s talk by Hansen, Naomi Wolf and a Canadian tar sands activist.
