I have been listening to the news and scientists for a while now and they claim that global warming is caused by "green house gases" trapping the suns heat AFTER it is reflected off of the earths surface. The Theory (as I was taught in the liberal college) was that depleted o-zone allowed harmful rays to enter the atmosphere, raise temps and then stay trapped. Or is science changing the laws of nature (again) to fit it's theories...... (sort of like evolution).

Many of you know I'm not an obama supporter. After seeing this is how his cabinet thinks I'm even more convinced our government is being run by a bunch of monkeys......

This "plan" is only a band-aid to eliminate the local hot spots created by large populated areas with large amounts of asphalt and lots of buildings. It will do nothing to allow the heat to escape out of the atmosphere.

Someone PLEASE correct me if I am missing the point on this article..... When did the whole global warming theory change at such a fundamental level...





Energy Secretary's White-Paint Proposal Puzzles Climate-Change Experts

Wednesday, May 27, 2009
By Paul Wagenseil



Energy Secretary Steven Chu stunned the audience at a London scientific conference Tuesday with a radical but simple proposal to combat global warming: Paint all the roofs of all the buildings in the world white.

If we did so, the Nobel Prize-winning physicist said, and if we also made sure the world's roads and sidewalks were light-colored, it would have the same effect on global warming as taking all the cars in the world off the world's roads for 11 years.

The idea is to harness the "albedo effect" -- the theory that a reflective planet warms up less as heat from the sun is bounced back into space.

Chu, speaking at the St. James' Palace Nobel Laureate Symposium, said the calculations are based on work done at Lawrence Berkeley National Laboratory, where he used to work and where three researchers concluded last year that changing surface colors in the world's 100 largest cities would offset 44 billion tons of carbon dioxide emissions.

But at least one science expert thinks Chu is nuts.

"It's past simplistic -- it's ridiculous," says Steven Milloy, publisher of junkscience.com and an avowed climate-change skeptic. "Imagine the glare on roads, in urban areas, imagine the UV radiation bouncing around. Snow blindness would be replaced by road blindness."

But Dr. Gordon Bonan, a climate scientist at the National Center for Atmospheric Research in Boulder, Colo., says there's a kernel of truth in the science behind Chu's idea.

"That's been a pretty standard idea many for many years now," says Bonan. "It's related to the idea of an urban heat island -- that a big city will generate a large amount of heat. In urban planning and urban design, the idea is that painting roofs white will absorb less solar radiation and keep the city cooler."

"In terms of roads, that does work," he continued. "You can test it yourself by walking barefoot on a hot summer day. The asphalt is going to be much hotter than the concrete and the white lines painted on top of the asphalt."

Still, it's not clear how well the practice would work on the world as a whole.

"You could try to extend this idea to the entire planet, but I've never seen any numbers on how much impact this would have on the Earth's surface temperature," says Bonan. "The urban [surface] area of the world is pretty small."

Milloy says he's certain that it would be a huge waste of time and money.

"How would this accomplish anything? What's the expense?" he asks. "This shows you how even Nobel winners get lost when they step outside their fields of expertise."

Bonan says that there wouldn't be any "unintended consequences," but Milloy disagrees.

"What if we do this, and solar activity decreases?" he wonders. "We need sunlight to make vitamin D. Plants need it to make photosynthesis."

It's well known that people in hot regions, such as Greece or the American Southwest, make sure their houses are light-colored to keep out the heat. But what about residents of colder climes, who might appreciate the extra solar boost from a dark roof during winter months?

"For a house, the heat loss would be pretty small," said Bonan. "It would depend on how well the attic was insulated."

As for the assertion that painting everything white would offset the greenhouse-gas emissions of hundreds of millions of cars for more than a decade, Bonan demurred that he wasn't qualified to judge.

Milloy was more critical: "It sounds like some dubious global-warming calculation that someone made on the back of an envelope."

Man where have you been?

its not Global Warming.... Its "Climate Change" now

I have very little fiath in any Scientist, its all about money.... what therory the paying party wants you to come up with.

Just more BS to scare people.

I'm not convinced that "global warming" OR "climate change" are happening. Everyone is operating on the assumption that the models are true. They are only models and what is actually happening isn't exactly what they had mapped out. Anyway, read for yourself.

Maybe it's because I am geting old,
but I do remember the late 70s when they were all up in arms about how we (humans) are causing another ice age.
Then in the 90s they have their panties in a wad over global warming.
and now the ocean currents are going back to where they cause a cooling trend, and so now it's currently called global climate change, and man is being blamed for that as well. It looks to me like it's Al Gore and his same greenies every time it gets brought up.

The fact is that there have been several ice ages over the history of our planet.
This fact alone tells us that the planet has warmed and cooled with out man's help on more than a couple occassions. No 2 strokes, no coal fired plants, and no huge metro cities to cause this.
It's a cycle.

Don't get me wrong, I'm not about running around poluting places with wreckless abandon either,
but look at the entire thing and use some common sence.

You are correct, planet destruction fear mongering has been around for a while. Don't forget about acid rain in the 80's. A fearful public is a compliant public.

The good news is that climate change meetings are good for the sex trade.
Helping the economy any way they can. Do they get carbon credits for that?

I have no doubts that the worlds climate is changing......none of you should.

The question is why is it changing, what do we have to do with it.

Everything I have read about global warming talks in 100 year periods......so whatever is happening, isn't happening quickly.

We really need to work on efficiency, cut back on our pollution, etc.....but there is no reason to get our panties in a bunch are try and come up with a quick solution.

I would be willing to bet that if (when) our planet becomes so hot, so cold, so polluted, just plain inhabitable......it will have little to do with us and more to do with the our ever changing planet + universe.
