Well that sucks. - gumby05, on 10/12/2007, -0/+11kites would have been built backwards of what they are now!
- inactive, on 10/12/2007, -3/+12Also, Western Europe (Britain, France....) would get MUCH colder if global warming takes off. (See the bit in the article about the Gulf Stream moving South? The Gulf Stream's what makes much of Western Europe warmer than Canada--they're at the same latitudes.)

- jaxxon, on 10/12/2007, -0/+6Heh.. I catch your drift.
- BESTenemy, on 10/12/2007, -0/+6My geography teacher taught the theory of Global Warming and reocurring Ice Ages side by side. There is something that could start as a global warming, but eventually have a pendilum effect.
There are many climate change models. Personally I hesitate to call what we're experiencing now "warming" or "freezing" as it could swing either way.
We could either have a green house effect continue to trap more heat, while releasing less in the form of infra-red radiation, or we could get to the point where ice caps melt and more earth is covered with water. However, only 10% of rising water levels will be cause by the glacier mass. Anyone that studied physics knows that matter expands when heated. 90% of ocean level change comes as a result of thermal expansion. Water has a better reflection coefficient than land and will reflect more visible light spectum back into space than it does now. In addition, the warming might result in greater evaporation and increased cloud cover. Those also reflect light back into space more efficiently than land does.
We might be experiencing a period of warming due to contribution of industrial age, but what is going to happen in 50 years or so when the cheap fossil fuels get used up (there'll always be oil and coal, it's just it'll be getting proportionally more expensive as supplies diminish)? What happens then?
Will the temperatures keep rising, or will they start to drop even quicker?
Most climate models go 50 years into the future as well as forcasts regarding the state of oil, coal and natural gas reserves.
I'm still curious to hear more theories. In early 90's many models were viewed side by side - global warming, freezing, dimming etc. Now "warming" is all we hear. It's prevalent in media, yet other scenarios that were popular never got discredited. They're just being avoided. - TyrannousDotNet, on 10/12/2007, -2/+7brrrr.
- Derrelicte, on 10/12/2007, -0/+4Very punny.
- Anrkist, on 10/12/2007, -0/+3That's the nature of science.. two things can't be right and when you are unable to prove conclusively that either are true, you ignore one of them and hail the other as "close enough".
- rkcrawf, on 10/12/2007, -0/+3Superman came during the last ice age and changed the earth's rotation after a massive earthquake. I thought everyone knew that...
- cyberghost232, on 10/12/2007, -0/+3This article blows.
- jackhole, on 10/12/2007, -1/+4RTFA. The hypothesis has nothing to do with the earth flipping or all weather systems changing course, it has to do with a strong polar air mass pushing the jet stream farther south, compacting the west-to-east mid-latitude wind we see now closer to the equator, resulting in its replacement by the subpolar east-to-west circulation.
- SuperJimmyJimbo, on 10/12/2007, -1/+3no William Shatner ( or Al Gore in this case) = no digg
- FlapJaw, on 10/12/2007, -0/+2This would have changed climates everywhere.. deserts would be reversed.
- MalDON, on 10/12/2007, -0/+2Uhmm, where I live, we have this magical thing called the East Winds... Gotta love Southern California.
- dmp1ce, on 10/12/2007, -0/+2Yes, but we are in a warm period.
http://en.wikipedia.org/wiki/Ice_age#Interglacials_and_the_future - rompom7, on 10/12/2007, -1/+3It didn't say weather systems move from east to west, it said winds blew east to west. It is perfectly reasonable to think that, considering that winds today sometimes blow that way. The Ice Age was a mysterious weather anomaly in the first place. And weird stuff like el nino could have had a hand in it.
- grendel, on 10/12/2007, -0/+2bunch of hot air if you ask me...
cold I mean. - waveman216, on 10/12/2007, -1/+2This is complete crap. It says they came to this conclusion by finding that moisture levels were near even on both costs but decreased heading west from the east coast. Isn't that pretty much exactly the way it is now?!!
Or was I dreaming when I saw the amount of trees steadily decrease as I drove west to California from Tennessee? - Quaoar, on 10/12/2007, -4/+5Well, since global atmospheric circulation is governed by the rotation of the earth and the drag on the atmosphere, it seems to me unlikely that global circulation was reversed at any time in Earth's history. Weather systems move from west to east due to the physics of the rotation vs atmospheric mechanics. Unless the earth was either inverted or rotating in reverse, this hypothesis makes no sense.
Q - Anrkist, on 10/12/2007, -0/+1There are theories that Earth has flipped on it Axis before.. which is probably where this theory came from.
- Technopundit, on 10/12/2007, -0/+1Reagan's, actually.
- atb12688, on 10/12/2007, -0/+1Yeah sounds awesome to me. Europeans deserve to see some cold weather and snow for once ;)
- Technopundit, on 10/12/2007, -0/+1Unless the earths rotational direction changed, I cannot see how this can be true.
- inactive, on 10/12/2007, -1/+1How many Ice Ages has the Earth went through already?
And the global warming after? Were they all "BUSH's" fault? - madformadness, on 10/12/2007, -1/+1Hey, AshTR. Stop hogging all the - diggs!
- JackyTreehorn, on 10/12/2007, -0/+0People would say "hello" when they leave and "goodbye" when they arrive.
- TheGuruStud, on 10/12/2007, -0/+0you mean Santa Ana winds :)
- xGORDOx, on 10/12/2007, -1/+1Damn Republicans in their SUV's
- BobInfinity, on 10/12/2007, -1/+1Aren't we in an ice age right now? There are still glaciers on earth.
- D4r7h3v1l, on 10/12/2007, -2/+1They could have just asked Ted Stevens...
- inactive, on 10/12/2007, -6/+4The article doesn't really make mention of any concrete evidence of this theory. How are we to believe this?
- hiikeeba, on 10/12/2007, -2/+0Personally, I blame the Republicans.
- Dested, on 10/12/2007, -7/+5No.
- sockpuppets, on 10/12/2007, -4/+1Except in Sovet Russia.
- zeptobyte, on 10/12/2007, -6/+2So this matters...... why, again?
- AshTR, on 10/12/2007, -20/+2Digg me up!
