NOVA: Dimming the Sun

PBS, NOVA ^

[IBIAFR]

"Dimming the Sun" investigates the discovery that the sunlight reaching Earth has been growing dimmer, which may seem surprising given all the international concern over global warming. At first glance, less sunlight might hardly seem to matter when our planet is stewing in greenhouse gases. But the discovery of global dimming has led several scientists to revise their models of the climate and how fast it's changing. According to one recent and highly controversial model, the worst-case warming scenario could be worse than anyone has predicted. "Dimming the Sun" unravels this baffling climate conundrum and the implications for Earth's future.

so now if we reduce polution more sunlight will reach the surface and cause faster global warming? I still want to know how the enviro-nuts explain the shrinkage of the polar caps on Mars.

So Marvin got this SUV from Wylie Coyote.....

Everything is a freaking catastrophe to these smartpants. And with all this global warming hysteria, our winters in the Chicago area have been milder. BFD.

"To find out what global dimming means for the fate of the planet, NOVA reports on the findings of the world's top climate detectives, including an American scientist who found a grim but crucial opportunity immediately following September 11, 2001, when the entire U.S. airline fleet was grounded for three days. This presented a unique opportunity to study the effects of airplane vapor trails on the atmosphere (see The Contrail Effect). Comparing changes in the daily temperature range showed that the absence of dimming from aircraft pollution alone made a marked difference to the temperature. This result hints at how much the effects of atmospheric pollution had been underestimated."


Color me a tad skeptical.

BS, the amount of sunlight has been increasing!

Because of the junk science of "global warming", the linkage between Earth's average temperature and the Sun's variability has been explored and documented. This is not what the "global warming" advocates had expected, but their efforts have advanced our current knowledge.

Actually, I find this to be the most important discovery of modern science, in the last 100 years. Our local star, called the Sun, is also a variable.

As a very long time astronomer, I have always wondered why our Sun was so constant, when almost every star in the sky is variable in some way. Even the north star Polaris is a variable and changes it's brightness.

The variability of our Sun will have profound implications for honest scientific study, once people get their heads out of their butts and realize that "global warming" was a political fraud.

Also: a reduction in visible light doesn't mean a reduction in total radiation-- more may have shifted to the infrared spectrum or the ultraviolet.

More evidence that the enviroweenies don't know nearly enough to substantiate the global warming claims they make.

I was wondering why I don't use sunglasses and sunscreen any more. /sarcasm

--This particular "study" took less than three days to discredit, IIRC--

Oh you're so harsh. C'mon, 3 days data is more than enough to justify taking measures that will depress the global economy for generations with no net positive climatological benefit. /sarc off...

[jocko12]

This is the start of a min-iceage.

[Trajan88]

"NOVA" must have been sitting under a tree.

It is going to be a hot 20006 summer here in N. Texas.

That's why stars "twinkle" (smile).

[finnman69]

This the opposite of accepted science regarding the sun. Eventually it will grow hotter and hotter, eventually becoming a red giant before shrinking to a white dwarf.

This summer will be hot...not sure about the one you refer to...won't be around to enjoy it. ;-)

"It is going to be a hot 20006 summer here in N. Texas."

Don't you worry a bit, the earth will be krispy fried by then.

[INSENSITIVE GUY]

Better stock up on blankets and coats now for the coming "ice age".The only catastrophy we really face is the catastrophy of people talking about the catastrophies.

BUSHS FAULT!

[Jaysun]

I know that the human-caused-global-warming kooks are wrong (and liars), but I also know that if they were right I'd choose a heat induced death over existing on berries and my own recycled whiz in their "utopia".

"Color me a tad skeptical."

Considering the average amount of water vapor in the atmosphere is 37,485,000,000,000,000 pounds, how much jet fuel would have to be burned to make a measurable difference.

[Sender]

20006 is nothing, what we really need to worry about is that the sun may only last another 5 billion years. So let's party like it's 19999.
