This is quite untrue. Basic theory says that a warmer planet will have more water vapor in the air, and this has already been detected
Boris:
basic theory also says that increased CO2 and increased water vapor will lead to addtional plant life
In addition, ice albedo feedback is uncontroversial and adds to the warming.
Ice sheets reflect sunlight back into space thereby cooling the planet.
You want science try this:
It has long been recognized that albedo related vegetation feedbacks amplify climate variability in North Africa. Recent studies have revealed that areas of very high albedo associated with certain desert soil types contribute to the current dry climate of the region. We construct three scenarios of North African albedo, one based on satellite measurements, one where the highest albedo resembles that of soils in the desert transition zones, and one based on a vegetation map for the green Sahara state of the middle Holocene, ca. 6,000 years ago. Using a series of climate model simulations, we find that the additional amplitude of albedo change from the middle Holocene to the present caused by the very bright desert soils enhances the magnitude of the June-to-August precipitation change in the region of the present Sahara from 0.6 to 1.0 mm/day on average. We also find that albedo change has a larger effect on regional precipitation than changes in either the Earth’s orbit or sea surface temperatures between 6,000 years ago and today. Simulated precipitation agrees rather well with present observations and mid Holocene reconstructions. Our results suggest that there may exist an important climate feedback from soil formation processes that has so far not been recognized.

Notice that the report does not mention CO2 as the cause of the desert formation of the Sahara. In fact the scientists think that it may simply be the change in albedo (sunlight hitting the surface) Albedo=Albedo is the fraction of solar energy (shortwave radiation) reflected from the Earth back into space.
Ice albedo does not add to warming…it adds to cooling. That is the positive feedback most climatoligists suggest causes the ice ages. As the ice forms more sunlight is reflected back to space thereby causing cooling summers and winters which causes more snow and ice to form which causes more sunlight to reflect out to space which causes more snow and ice. Etc.
hmm see a pattern here? Seems like the amount of sunlight hitting the earth plays some “UNKNOWN” part in global warming/cooling. Let’s take it further. water is less reflective than ice thus as ice melts (esp sea ice) than more energy is absorbed into the ocean heating the ocean causing more ice to melt causing more sunlight to be absorb etc. This is a positive feedback for warming. notice again CO2 is not mentioned. However as the oceans warm the gas able to be held with in oceans is lessened thereby releasing CO2. since the oceans holds 50 times more Co2 than the air. the warming of the oceans may be adding to the CO2 in the air.
what role does CO2 play. Oh yes the greenhouse gas theory which states that the reflected light is trapped due to its wavelength change. So more Co2 must mean higher temps right? well not so fast. The increased Co2 also stimulates plant growth which acts like a carbon sink, also the warmer oceans cause more plant life like alge to form which draws more Co2 into its sink and settles on the ocean floor. Also the increase rainfall caused by the addtional water vapor will speed the erosion of silcate rocks causing more production of limestone rock thus causing another carbon sink to form.
So you say? the rate of CO2 has never gone up this fast before and we are still all doomed because the earth can not keep up. Well not so fast. the earth has seen rates of Co2 much higher than today’s numbers. infact about 550 Million years ago Co2 was 350 times higher than today’s numbers. this equates with a huge explosion in new life forms.
In short climate is effected by many things including Co2 like sun activity, the rotation of the earth, the ground cover or lack of such, the wethering of rocks,, the formation of soils, the formation of clouds, the concetration of the oceans. To say that CO2 is the only cause or even a very big cause is to not understand the science of climate, geology, meterology, the galcier cycles, the sun cycle, the effects of plant life and animal life on climate, the convenction cycles of oceans, the volcano cycle of the earth, the movements of landmasses due to tectonic forces, the chemical reactions of all parties involved. Blaming CO2 for the entire cause of warming is very lazy science and very blindsided thinking.
