It's nice to get a measured comment from you. My guess, and it's only that, I could easily be wrong, is that the current CO2 increase is mostly due to the apparent cyclical nature of CO2 -Temp that is evident in the ice core studies, and that the effect of the anthro CO2 on top of this natural increase will be small because of the buffering capacity of the atmosphere. If the anthro CO2 was much larger than it is then I'd be very concerned that the buffer capacity of the atmosphere could be exceeded. But, as we now know, the natural sourcing and sinking of CO2 is huge, more than two orders greater than the anthro CO2 produced -- keeping in mind that all these numbers have considerable error associated with them. But we'll see.

The 40% increase in CO2 over the last two hundred years is due to man. It occurred when we started burning fossil fuels. We know how much we have put in the air. The isotope signature shows it from man. There is no question about this. It is not some natural cycle.
And I just said. It was due orbital changes. Malankovitch cycles. This is elementary stuff that you could have easily determined yourself by using Google. But the large swings are due to the feedback of CO2/water vapor/ice and temps. Were it not for CO2 there would not be the large swings.
scientists could just as easily say when the earth warms the ocean releases CO2 to modulate (or as nasa would say, co2 acts as a thermostat) the effect of the the forcings causing the warming.
(note all the data shows co2 trails warming. I have produced the studies multiple times)
There are studies showing CO2's warming effect decreases logarithmically. (let me know and I will produce the study again) So the first layer of co2 traps heat but as you add co2 is has a smaller and smaller warming impact.
We also Know that NASA says co2 is a thermostat and a coolant. So as you add more of it, CO2 makes the earth more opague to sunlight and the suns energy. A cooling feedback.
Also note... If... adding co2 does cause a water vapor feedback... we know that as you add low clouds you block the suns energy from reaching the surface.
Finally, another cooling feedback is that a NASA study recently stated that more CO2 means more plants. Which means the plants eventually eat the co2.
The earth cycles every 10 to 20 thousand years... because it is a very dynamic open system.
Its fraudulent to argue co2 only works one way it such a beautiful and complex system without any science to back you up.

No they can't and they don't.
No it is not fraudulent to say that increasing levels of CO2 can only lead to to warmer temps, all other factors being the same. It is common sense and is the reason 97% of the world's climatologist and all of it's science orgs agree; man's release of CO2 has increased the GH effect which has raised the temps.
CO2 is only acting to cool the stratosphere. It has been doing so. Strat temps have been going down as tropo goes up due to increasing CO2. The CO2 in the tropo is preventing heat from going into the strato. The CO2 in the tropo is holding the heat in the tropo. The effect is essentially arithmetically linear as concentrations increase in the time frame we are interested in, which is within the next thousand years.
As NASA says, and you still perversely and insanely distort......the levels of CO2 are analogous to the setting on the thermostat that determines the temperature of the planet. The higher the level of CO2, the higher earth's temps.
BTW.........GORE IS/WAS RIGHT !!!! LOL It must kill you.
no you troll... a thermostat modulates (or contains) the temperature in a zone.

CO2 rejected 95% of the Solar energy to keep the earth cooler.
http://science.nasa.gov/science-news/science-at-nasa/2012/22mar_saber/
âCarbon dioxide and nitric oxide are natural thermostats,â explains James Russell of Hampton University, SABERâs principal investigator. âWhen the upper atmosphere (or âthermosphereâ) heats up, these molecules try as hard as they can to shed that heat back into space.â
Thatâs what happened on March 8th when a coronal mass ejection (CME) propelled in our direction by an X5-class solar flare hit Earthâs magnetic field. (On the âRichter Scale of Solar Flares,â X-class flares are the most powerful kind.) Energetic particles rained down on the upper atmosphere, depositing their energy where they hit. The action produced spectacular auroras around the poles and significant1 upper atmospheric heating all around the globe.
âThe thermosphere lit up like a Christmas tree,â says Russell. âIt began to glow intensely at infrared wavelengths as the thermostat effect kicked in.â
For the three day period, March 8th through 10th, the thermosphere absorbed 26 billion kWh of energy. Infrared radiation from CO2 and NO, the two most efficient coolants in the thermosphere, re-radiated 95% of that total back into space.

sceince.nasa.gov just explained it to you...
the whole point of the experiment was to show that co2 acts a a thermostat.
CO2 It acted a powerful coolant by rejecting the heating energy of the sun... hence working to keep the temperature where it was set.
you sell air conditioners.... when you have it set at 72 and the sun starts warming up the house what does the thermostat do? that is what a thermostat does you moron... it helps you keep a set temperature.
there was nothing in the article about adding more co2 and changing the temperature of the stratosphere or earth. it was that CO2 repelled most of the heating energy to keep the set temperature.
And finally to show how much of a moron you are...
you have been telling us CO2 has gone up by 40 percent... yet temperature has not gone up in 17 and half years.
Sure... co2 is doing a great job of setting the temperature.... that is why co2 trails the change in temperature.
you are a such a troll.

All that conjecture is now called into question by the recent work. Robert Schneider's work at Bern is especially relevant but there are many other great papers in the recent literature.
