Writing in the latest issue of the journal Proceedings of the National Academy of Sciences, the CIS scientists unveiled new research that shows increased carbon dioxide levels cause plants to retain water that otherwise would have evaporated from their leaves, entered the atmosphere and helped cool the planet.


Water vapor does not cool the planet. How can anyone have faith in this shit?

Water vapour caused one-third of global warming in 1990s, study reveals

Experts say their research does not undermine the scientific consensus on man-made climate change, but call for 'closer examination' of the way computer models consider water vapour
 
Yeah, but that would require one theory replaces the other, not both theories exisiting at the same time! WTF are you smoking? I'll take an Oz
 
I'm thinking they meant that it helped cool the planet in some way; the greenhouse effect that water vapor provides obviously wouldn't help. I'd have to read the paper to figure out exactly what they meant. :-/
 
the real questions should be 1)how many idiots will believe this bullshit claim and 2)how hard will the eco-nazis try to push this insanity.

They are clear about what they meant. they claim that plants not retaining water leads to cooling, or the inverse, plants retaining water will warm the planet. So obviously, we can't water our plants and we're going need to create a whole new industry to monitor the boisphere and be certain we keep plants at their current, most perfect water content. This should create about 10 zillion new jobs. We'll tax anything that has to do with plants to pay for it.
 
95% of the greenhouse effect is what I've read also. I believe the IPCC accepts this figure as well. Hopefully one of the warmers here can verify with their sources (I'm told they have superior sources of data to choose from)

Oh, I really wish Cypress could post the science that would clear up my ignorant misconceptions.

Please, dear warmers-- Ib1, Cypress, (Not you Desh... just too stupid)-- please! I beseech you, teach us your ways. Include us in your great knowledge

Oh, it's really easy... Most of the greenhouse gas is water vapor... Increased man-made CO2 is causing plants to absorb and retain more water, which isn't turning into water vapor, and is allowing the earth to cool because the greenhouse effect (caused mostly by water vapor) is diminished. What's interesting is how it's 180 degrees from the Global Warming theories, whereby we were creating TOO MUCH of a greenhouse effect!
 
From what I understand? Global warming is melting ice caps, increasing water vapor in the air. COLD water vapor. These cold fronts are responsible for all the snow that the USA has been getting. Since heat retreats and draws in the cold rapidly(like a vacuum). That is why Cold fronts move faster then WARM(editted) fronts.
That is why there has been more snow in the USA then Canada.

Water vapor directly does not cause global warming. It is more like a conductor(cold and heat) than a heater. The CO2 is a heater. Therefore, This article may be inaccurate. Though this is just my opinion.

The increased carbon dioxide would just make plants grow faster, work harder to convert CO2 to oxygen. Though other toxins associated with pollution hamper this ability. Retaining water(whether it does or does not) when the planet is actually heating up, would be a good thing. Keeping the plant cool and able to do its job.

I'd stick to lawn mowing if I were you, Professor.

You totally bungled and misconstrued what the article said.

While your science blog article is admittedly a poorly-written piece of journalism, the careful and scientifically-astute reader can easily understand what is being presented.

They're not talking about the greenhouse properties of the gaseous form of water vapor.

They're talking about the physical process of evaporative cooling; i.e. they're talking about a physical and biological process that's entirely different and distinct from the greenhouse properties of the gaseous phase of water vapor. Obviously, you didn't understand the distinction. Like I said, don't you have some light bulb fixtures to change?

Evaporative cooling. Ever heard of it? Do you know how a swamp cooler works? Are you vaguely familiar with the physical properties by which perspiration cools your body? Guess not...


Even if you were easily duped by a poorly written science "blog", this information is easily available from the original Carnegie Institute source:

Carnegie Institute:

“Plants have a very complex and diverse influence on the climate system,” says study co-author Ken Caldeira of Carnegie’s Department of Global Ecology. “Plants take carbon dioxide out of the atmosphere, but they also have other effects, such as changing the amount of evaporation from the land surface.

Plants give off water through tiny pores in their leaves, a process called evapotranspiration that cools the plant, just as perspiration cools our bodies. On a hot day, a tree can release tens of gallons of water into the air, acting as a natural air conditioner for its surroundings. The plants absorb carbon dioxide for photosynthesis through the same pores (called stomata). But when carbon dioxide levels are high, the leaf pores shrink. This causes less water to be released, diminishing the tree’s cooling power.

The warming effects of carbon dioxide as a greenhouse gas have been known for a long time, says Caldeira. But he and fellow Carnegie scientist Long Cao were concerned that it is not as widely recognized that carbon dioxide also warms our planet by its direct effects on plants. Previous work by Carnegie’s Chris Field and Joe Berry had indicated that the effects were important. “There is no longer any doubt that carbon dioxide decreases evaporative cooling by plants and that this decreased cooling adds to global warming,” says Cao. “This effect would cause significant warming even if carbon dioxide were not a greenhouse gas.”

Carry on with the lawn mowing, Professor.
