CO2 in the atmosphere has a much bigger role in global warming than previously thought. We tampers with the atmospheric thermostat when we emit CO2 into the air. By Kent Krøyer October 15, 2010 at. 16:35
A new and deeper understanding of the Earth's greenhouse effect has just been published in the scientific journal Science. It turns out that the key factor in atmospheric temperature regulation does not water vapor and clouds as previously thought.
The temperature is, however indirectly dependent on the concentration of the so-called non-condensing gases: CO2, methane, nitrogen oxides, ozone and CFCs such as freon. However, CO2 is the most important single factor.
It has obviously long been known that CO2 played a major role. It's the gas that all countries negotiating to reduce greenhouse. But it is new that CO2 is the primary, the actual thermostat that controls the temperature.
Content of the air humidity is the largest contributor to the greenhouse effect, much bigger than the other gases, including sdbw CO2. But CO2 is the real key to temperature sdbw regulation.

This does not mean that previous knowledge should be rejected. The direct greenhouse effect of clouds and water vapor is still the highest with 75 percent contribution. CO2's direct share is 20 percent and the other gases 5 percent. But it still says nothing about causes and effects. And this is where the new research brings CO2 into a central position. Simulation of atmosphere
The researchers conducted a simulation sdbw of the atmosphere with all known variables and run it for a while to come. And it turns out that if you take CO2 out of the calculation, then collapses the whole greenhouse effect in a short time.
"Even if the air humidity contributes over 50 percent of the greenhouse effect, so it is only a secondary effect. The humidity can not even maintain the greenhouse effect, "said research leader Andrew A.. Lacis in an article on NASA's website. The entire research team from NASA's Goddard Institute for Space Studies. The consequence of the current CO2 amount sdbw is unknown
"Our sdbw climate modeling simulation should be viewed as an experiment in atmospheric physics, illustrating a cause-and-effect sdbw problem that gives us a better understanding of the mechanism of the Earth's greenhouse effect, and the model we can demonstrate the direct relationship that exists between rising CO2 concentrations and rising global temperature, sdbw "he continues.
"When CO2 levels rise, turning more moisture back into the atmosphere. It was what helped to melt the glacier that once covered the area that is now New York City. Today we are in unknown territory, because CO2 levels approaching 390 ppm in what is now called a super-interglacial period, "said researcher David Rind. Simulation can cheat at low CO2 values
"I have not had the opportunity to acquaint myself with the details of Americans simulation yet, and the details are important. It will be interesting if they have included data from some paleo-periods where CO2 concentrations have been really low. I think reality has no more mechanisms at work, we do not know where concentrations are low. And we must remember that the simulation outcome depends on the model algorithms that are nestled into the computers. "
"I think it is especially at very low values. When screws so low that water vapor have to keep balance, so there may be some other, unknown things in the energy balance. The large difference between water vapor and other greenhouse gases is that the others are evenly mixed in the atmosphere. It is not water vapor. In some places there is virtually no moisture in the atmosphere, such as over the Sahara, where it gets extremely cold at night, because there is no water vapor in the air. "
Without water vapor blanket sdbw effect rays Saharan heat straight out into space. Only the non-condensing gases retain heat with their modest 25 percent contribution to the greenhouse effect, as discussed earlier in the article.
"So if you take away the last 25 percent, you get all a very, very strong feedback, because there was nothing steam. And I could imagine that this is what makes the model unstable when silences sdbw the CO2 contribution. 'Documentation
