cynical writes "Just in time for the opening of The Day After Tomorrow, the futurism/technology/environment blog WorldChanging has an interview with futurist Doug Randall, co-author of the "Abrupt Climate Change" scenario [PDF] commissioned by the Pentagon earlier this year. The report generated a storm of controversy a couple of months ago, and drew attention to the possibility that global warming could disrupt things enough to trigger a rapid-onset ice age. Now that the furor has died down, Randall can talk about climate change, how the report came to be, and just what he thinks about the new disaster movie."

However, it just goes to show; make a movie about a meteor hitting earth and we spend billions on searching for NEO's (near earth objects), make a movie about climate change and all of a sudden we are at risk from "Abrupt Climate Change". The planets lasted this long already, I personally am not too concerned.
However, I do think they should make a movie about how all geeks get laid daily!

Whereas I share your view (to an extent, it wasn't billions!) on the knee-jerk reactions to disaster films, it's not the planet that really has anything to care about - the moon was formed when the planet was hit by a rock, and the planet is still here. It could happen again. Anything living would be from a time after that event, of course. Anything. The planet itself is fairly resilient, even when it came close to being completely destroyed.

I'm tired of fucking Earth Day, I'm tired of these self-righteous environmentalists, these white, bourgeois liberals who think the only thing wrong with this country is there aren't enough bicycle paths.

Narrow, unenlightened self-interest doesn't impress me.
Besides, there is nothing wrong with the planet. Nothing wrong with the planet. The planet is fine. The PEOPLE are fucked. Difference. Difference. The planet is fine. Compared to the people, the planet is doing great. Been here four and a half billion years. Did you ever think about the arithmetic? The planet has been here four and a half billion years.

Two hundred years versus four and a half billion. And we have the CONCEIT to think that somehow we're a threat? That somehow we're gonna put in jeopardy this beautiful little blue-green ball that's just a-floatin' around the sun?
The planet has been through a lot worse than us. Been through all kinds of things worse than us. Been through earthquakes, volcanoes, plate tectonics, continental drift, solar flares, sun spots, magnetic storms, the magnetic reversal of the poles...hundreds of thousands of years of bombardment by comets and asteroids and meteors, worldwide floods, tidal waves, worldwide fires, erosion, cosmic rays, recurring ice ages...And we think some plastic bags, and some aluminum cans are going to make a difference? The planet...the planet...the planet isn't going anywhere. WE ARE!
We're going away. Pack your shit, folks. We're going away. And we won't leave much of a trace, either. Thank God for that. Maybe a little styrofoam. Maybe. A little styrofoam. The planet'll be here and we'll be long gone. Just another failed mutation. Just another closed-end biological mistake. An evolutionary cul-de-sac. The planet'll shake us off like a bad case of fleas. A surface nuisance.
You wanna know how the planet's doing? Ask those people at Pompeii, who are frozen into position from volcanic ash, how the planet's doing. You wanna know if the planet's all right, ask those people in Mexico City or Armenia or a hundred other places buried under thousands of tons of earthquake rubble, if they feel like a threat to the planet this week.

The gravitational binding energy of the Earth is U = GM^2/R, where G is Newton's gravitational constant, M is the mass of the Earth, and R is its radius. Plugging in the appropriate numbers (see Wikipedia [internet-e...opedia.org]), you get 2.24x10^32 joules. For reference, if a ton of TNT is 1 billion calories (4.184 billion joules), then that works out to be 5.35x10^22 tons of TNT, or about 50 trillion gigatons. By way of comparison, I think I read that the world's nuclear arsenal at the height of the Cold War was somewhere between 20 and 50 gigatons.

God, I hate this myth, especially the "laughs in derision" part. Einstein's work was immediately recognized by "all those tenured professors" as having immense value, being a unified explanation of some serious problems with classical physics that had been bothering physicists since the mid-19th c.; there may have been those who disagreed with some aspects of his work (as, indeed, they were right to do; note that we still haven't unified relativity with quantum theory) but controversy is not the same as derision. Einstein's major papers were published in respected, established journals managed by those old fuddy-duddy academics you decry.
Newton, Darwin, Watson and Crick -- pretty much all of them worked their way through the scientific establishments of their day. Every once in a great while a major breakthrough is greeted with open derision (e.g., Mendeleev's periodic table) but the vast majority of those dismissed as crackpots are, in fact, crackpots; and the vast majority of scientific advances come from scientists working within the established system.

Re:Can someone calrify (Score:5, Informative)
The thing which people do not understand about global warming is that it sooner or later brings the gulfstream to a standstill due to decrease in water salinity in the arctic. As a result New England, Iceland and most of Wester Europe freeze as the temperature drops down by up to 9C. After all, London is at the lattitude of Alaska and the only thing keeping it warm is the Stream.
Latin America overheats and goes into a draught. There are some effects going as far as changes in the monsoon patterns and draughts in South East Asia.
This is also the reason why you cannot indiscriminately use historic data sets about climate without weighting. This is also the reason why a recently published right-thinking-tank flamebait (honoured on Slashdot) that the original global warming research is flawed because they did not use all data including Texas is what it is - flamebait. Texas is probably the only place to go cooler in such an event because the rain that currently drops on Latin America will drop there.
The simulations have been run many times and the result is always the same. In fact sod the temperature, the most scary fact of global warming is the gradual decrease of flow in the antigulfstream and water salinity which have been picked up for the last several years.
For a lamers overview see this: http://www.bbc.co.uk/science/horizon/2003/bigchil
For non lamers - see Science as well as a few other magazines where the results have been published over the years
Also, I am not amazed that the Pentagon has asked for this. The most scary part of global warming is the stop of the gulfstream and the 2+ billion of hungry and thursty armed people on the move. Some of them with nuclear weapons...

I have to admit, I did not do a full RTFA before doing the previous post.
Here are my 2p after reading the rest of it.
There are several incorrect assumptions in this article:
It forgets to account that EU deliberately expands towards less affected countries. It also forgets to notice that the agriculture in all of EU except Poland, Italy, Spain and possibly South France lives only on life support. If British, German, Northern France agriculture will die for climate reason the shelves in the supermarket will not even change and the Mediterranean regions are not going to be affected that much. Poland, Bulgaria and Romania are largely outside the affected zone (if the british met simulations are to be believed). After they join the EU (Poland already, BG and RO in 2007) EU will go fully selfsufficient in agriculture even if UK, DE and Scandinavia will freeze.
It forgets to mention that another least affected country - Russia. There will be some cooling around St Petersburg, Baltic, Murmansk, but the rest of the climate will stay where it is and it is largely selfsufficient.
The assumption that US is selfsufficient is deeply flawed. Nearly all large agricultural states in the US will be hit by either draught or multiple class 5 hurricanes per year. So in fact US is the only place that cannot fold into itself (yeah, we know who ordered the report and what do they want to hear).

Unfortunately, people often take fantasy (i.e. "JFK") and turn it into their reality because they are too intellectually lazy to find out whether something on the big screen has any basis in reality. Too many people just guzzle the shit that the media pumps out to them without questioning any of it. That goes for for left, right, and plain old profit-seeking media alike.

No. The thing to do is adapt.
Climate change will come with humans, or without. It's been going on since long before humans arrived on the scene, and there is no reason to believe it'll stop just because we ask it nicely.
There is also no reason to believe we know enough, or have power enough, to hold the planet's climate in long-term stasis. So let's forget that option.
Concentrate on what we CAN do.
If we are shifting the CO2 balance in the atmosphere, then work on fixing our contributions. But don't expect that because we stop adding CO2 to the atmosphere, that the CO2 balance will stabilize. There's no reason to believe it will, and even less reason to believe that the "historical" level is some magical stable point.
Another thing we can work on is becoming less dependent on environmental fresh water. Rain is all well and good, but if we don't start making our own fresh water soon, we'll be in deep before too much longer.
Same with food supplies - too dependent on weather. We've been able to grow things hydroponically and aeroponically for a long time, so it's time to start looking at them in the large scale. It'll help in all sorts of interesting ways, not least will be reduction of our (current) need to dump fertilizer into the Gulf of Mexico.

Another post aluded to aliens visiting; given the absurdity of the environmental effects visible in the movie, it actually is no less absurd to show an alien ship arriving, causing this damage and then leaving, than to have these environmental effects.

This might sound doubtful, but the earlier part of this evidence can be cross checked with more obvious sources, such as tree rings (more than a thousand years) and sediment layers in lakes (thousands of years.) There is a great deal of fossil evidence, of which the best comes from pollen and hard-shelled micro-organisms (e.g. diatoms.) These (when embedded in countable sediment layers) tell us when conditions allowed the organisms to live in a particular locale. Beetles are also very useful, with many temperature-sensitive species having conserved their morphology for quite a long time (a million years.) In general, the most useful species are small organisms with hard parts; these leave more remains and travel less than larger organisms (a rare fossil could easily be in an atypical location.)

The world's climate does indeed vary on many different timescales and for many different reasons - it even gets a little hotter every 100,000 years or so! In fact it's in a hot period right now; that is why you haven't noticed that we are living in an ice age. The reason for the cycle is not magnetic fields, but rather the shape and timing of the earth's orbit around the sun (the amount of eccentricity, the amount of "wobble", and the timing of northern summer relative to the orbital position are not constants.) This is the "Milankovich cycle."
The people who think that human activity might make dramatic short-term changes in the earth's climate know all this and try to take it into account.
