Global Warming
The greenhouse effect, a look at the Kyoto Protocol and a history of the Earth's climate.
Leonard Druyan, who co-authored the study, says it will not only be much hotter, but less rainy, especially in the summer months, reports CBS News correspondent Randall Pinkston.
“Based on our study, the amount of global warming might be even more than previously thought,” Druyan, said.
Previous and widely used global warming computer estimates predict too many rainy days, the study says. Because drier weather is hotter, they underestimate how warm it will be east of the Mississippi River, said atmospheric scientists Barry Lynn and Leonard Druyan of Columbia University and NASA's Goddard Institute for Space Studies.
"Unless we take some strong action to curtail carbon dioxide emissions, it's going to get a lot hotter," said Lynn, now a scientist at Hebrew University of Jerusalem. "It's going to be a lot more dangerous for people who are not in the best of health."
The study got mixed reviews from other climate scientists, in part because the eastern United States has recently been wetter and cooler than forecast.
Instead of daily summer highs in the 1990s that averaged in the low to mid 80s Fahrenheit, the eastern United States is in for daily summer highs regularly in the low to mid 90s, the study found. The study only looked at the eastern United States because that was the focus of the funding by the U.S. Environmental Protection Agency, Lynn said.
And that's just the eastern United States as a whole. For individual cities, the future looks even hotter.
In the 2080s, the average summer high will probably be 102 degrees in Jacksonville, 100 degrees in Memphis, 96 degrees in Atlanta, and 91 degrees in Chicago and Washington, according to the study published in the peer-reviewed journal Climate.
But every now and then a summer will be drier than normal and that means even hotter days, Lynn said. So when Lynn's computer models spit out simulated results for July 2085 the forecasted temperatures sizzled past uncomfortable into painful. The study showed a map where the average high in the southeast neared 115 and pushed 100 in the northeast. Even Canada flirted with the low to mid 90s.
Many politicians and climate skeptics have criticized computer models as erring on the side of predicting temperatures that are too hot and outcomes that are too apocalyptic with global warming. But Druyan said the problem is most computer models, especially when compared to their predictions of past observations, underestimate how bad global warming is. That's because they see too many rainy days, which tends to cool temperatures off, he said.
There is an established link between rainy and cooler weather and hot and drier weather, said Kevin Trenberth, climate analysis chief at the National Center for Atmospheric Research. Rainy days means more clouds blocking the sun and more solar heat used to evaporate water, Druyan said.
"I'm sorry for the bad news," Druyan said. "It gets worse everywhere."
Trenberth said the link between dryness and heat works, but he is a little troubled by the computer modeling done by Lynn and Druyan and points out that recently the eastern United States has been wetter and cooler than expected.
A top U.S. climate modeler, Jerry Mahlman, criticized the study as not matching models up correctly and "just sort of whistling in the dark a little bit."
But Andrew Weaver of the University of Victoria, editor of the journal Climate but not of this study, praised the paper, saying "it makes perfect sense."
He said it shows yet another "positive feedback" in global warming, where one aspect of climate change makes something else worse and it works like a loop.
"The more we start to understand of the science, the more positive feedbacks we start to find," Weaver said.
Weaver said looking at the map of a hotter eastern United States he can think of one thing: "I like living in Canada."

Great job killing our world, you scum.
Burn in hell.
You must work for Exxon-Mobil. Your post is total nonsense.
Fellow citizens, the truth is that our present can only be as stable as our future.
For too long we have hobbled from decade to decade, generation to generation, and millennium to millennium, myopically adhering to superfluous battles that can never be won. Never once as a species forwarding or embracing an all encompassing path towards a certainly better future.
Our excuses have been many, our reasoning mostly incoherent, and our lack of vision as a species, certainly fatal.
For in the meantime, as each tick of the ages has passed, the critical threats posed and ignored by our species discordance have increased exponentially.
Pandemic famine and disease, massively destructive weapons, fatal atmospheric and climate change, super volcanic eruptions, catastrophic space body impacts, Orwellian societies of unparalleled oppression, and many other global catastrophes too numerous to list here, waiting to befall us at any moment.
...
My friends, the truth is that if we do not fight for and secure freedom today, the time will very soon come when it will be almost impossible to do so.
In retrospect, when one soberly considers the critical challenges that we must face together to survive as a species, our differences, at times, can become almost imperceptible.

ENERGY policy: Big Oil
FOREIGN policy: AIPAC
HEALTHCARE: Pharma
FISCAL policy: Wall St booms while the middle class starves
NATIONAL DEFENSE: perpetual war that will only profit the corporate war machine at the expense of the troops, their families and the hundreds of thousands of innocents that get slaughtered around the world because of our policies.
EPA: Exxon-Mobil Protection Agency
EDUCATION: why ?, best to keep the masses stupid and gullible ..
RELIGION: best to educate with myth, more pliable than the truth -
... the middle class is insignificant to the Republican Party - they seek a ruling elite and a vast working poor which consolidates wealth and power for their corporate masters, leaving very little for "we the people". America is quickly becoming a third world country riddled with debt under Republican greedership. Is this the way of life we want to protect ? Is this the America we grew up with ? Time to wake up sheeple !
Besides, aren't the oceans supposed to rise and engulf India and China? (Nobody buys that hokum either.)
The reality is, we could easily reduce pollutions emissions; light rail and getting people to live on a schedule from time to time. We'll always need oil, so the oil executives will never go broke. They do that in China and other countries, so why not in the United States?
It's not your country. It's The Rich Peoples' country just as it always has been. What you think doesn't matter. You're allowed to go to the voting booth to choose between Tweedle dee and Tweedle dum (dum won the last 2 elections) and watch television. You're allowed to grime so long as it's ineffectual. Wake up and join the real world.
Now let's consider campaigns of the past: swine flu, bird flu, Y-2-K, WMD's in Iraq. Lastly, consider that scientists only have climatic records for the past hundred years. Time will tell, and I'm certain select groups are going to get wealthy.
Besides that closet **** head of the evangelical church that GW talked to every Monday morning said GW was ordained by God to invade Iraq and make the holy land safe. Also, he said the Rapture is coming anyway, why not speed it along for a little additional $profit$ for the Bush family twin's and Cheney's daughter's trust funds...
This is so NON-NEWS that it's laughable. The summer of 2085 MIGHT be 10 degree warmer than the summer of 2005, when the summer of 2006 was already 5 degree cooler than average?
Come on, your just looking to fill empty space in the newspaper from lack of advertisers, how pathetic.
What will be 10 degrees warmer this summer will be the news reporting of every single heat wave that hits and claiming that proves human-caused global warming. But when there's a cold weather event, like this past April being one of the coldest on record, we're told you can't disprove human-caused global warming by an isolated incident.
It's the new consensus of double-speak and ridiculing doubters.
And so it continues. A "prediction" of the weather 70 years in the future that is taken as fact like it's already happened.
Did anyone notice that April was one of the colder ones on record? No questioning of human-caused global warming then.
But wait til this summer when the first heat wave hits, like heat waves hit every summer.
Then all you'll hear in the news is how it's our fault.
For some reason my posts don't seem to be getting on the board. Must be global warming...

Well I guess you will gamble you and your families lives on YOUR opinion of EXPERTS. Good luck IDIOT!!

Hey no problem. YOU Crackers will toast and toast to a nice golden brown if these folks are right. Since you refuse to look any further into the matter than what the weather was like last month... since you scope of the issue before us is to ignore the VAST and OVERWHELMING views of people who have studied their entire lives, I guess you deserve to roast to that golden brown. Sieg Heil Y'all. ROFLMAO

So in your poor fascist mind all this is about POLITICS? ROFLMAO I have often wondered about you fascist and how you live with such small and insignificant minds. If history is any indication we will be FAR better off under a Democratic Administration than under a Southern Fascist Rule. Regardless though this isn't POLITIC'S it's SCIENCE and you Fascist do not have a very good record on that issue. No, you record on issues of the enviroment, when looking at history is nothing but ZERO... Na Da, Failure. So I guess I'll go with the experts Sieg Heil Y'all.
I agree with you.
And, thanks to the housing bubble that was created by Greenspan and Co to replace the dot.com bubble, there are going to be a lot of homeless people (via foreclosures) baking in the sun.
I can only sum up that these so called Security Moms were nothing more than Security Idiots. Unless your name is Halliburton, the GOP is not REALLY interested.
Irrigating desert areas with waste water and planting trees would remove much carbon, provide shade and *** water run-off.This plan is opposed by ecologists wishing to preserve the desert ecosystem. Don't worry about it. Some deserts will get fried anyway if we don't cool down a bit. We will always have a desert. And if we If we don't solve the problem soon, Antarctica may become a desert ecosystem.
Accelerated water run-off is a big part of the problem. We return water too quickly to the sea without letting it perk through the earth.
The roots and life processes of plants slow waters' return to the sea. The shade helps cool the land.
Planting trees now and irrigating them is a more sure solution than expecting nations to de-industrialize.

You are quite welcome. Now, go get a job.
Um, buddy; Antarctica already is a desert ecosystem. Desert means dry, not hot. *** with the planet even more is a very bad idea. How about instead we DRIVE LESS.
It is more poductive to slove a problem with a less than perfect method that will work, than insist it be solved with a method the Sierra Club likes, but that no one will actually do.
We could all drive less individually, but the industrilization of India, China and Brazil means more cars and more factories, so that means more emissions overall. Individually people may be convinced to drive less, but on the shear number of new drivers means more emissions.
We could have gotten cheap electricity from hydro-electic sources and nuclear powerplants, but this was opposed also. I remember some ecologist friend of mine saying, "America has enough coal and other fossil fuels to power it's industry for 300 years, so we don't need nuclear power!" They won the argument, but now we have carbon in the atmosphere and are suffering for it.
The point is, well meaning people reject solutions that can work and champion programs that sound good, but that no one will actually do.
Planting more trees and irrigating arid land will help right now. It is faster to do this than build new power plants or control driver behavior.
