So what? Where's the data that says 40% has any impact? How do we know that 400% would have an impact measurable on a geological scale? I'm not arguing with you on greenhouse gas qualifications or the amount CO2 has gone up (I don't know enough about it to say either way).
The article about the coldest temperature ever recorded seems to go against the text summary on your chart. So yes, oops for your argument.

I will tell you why. I am a conservative who believes we should conserve and protect the environment - properly with due care... and you leftist drones have been helping the leftist politicos, pr people and compromised climate guys siphon off billion of dollars which could have gone to cleaning the oceans or the air. now the leftists are attempting massive wealth transfers and restrictions of liberties with cap and trade and UN wealth transfers. finally, I just like to see the truth get its due. the truth is the data shows change in temperature precedes change in co2 levels. So while co2 could have an amplifying effect we have no idea how significant it is. But, the more data we have the less significant CO2s warming effect seems to be in our current environment.
CO2 is, by various estimates, responsible for 10 - 24% of the immediate greenhouse effect and and a much larger factor of long term temperature regulation of the earth right? The level of CO2 in the atmosphere are analogous to the setting on a thermostat. BTW Didn't you have me ignore?
show us the data to back those wacko claims up. the models making those claims have failed. without some sort of multiplier effect there is no chance co2 does that. the very recent models have tried to say more co2 means more clouds via multiplier effect. the issue with that is there are other recent studies showing the clouds may have a cooling effect.
Yes the levels of CO2 in the atmosphere largely regulate the earth's temperature. Because CO2 is a greenhouse gas and we have increased it's level by 40% so temps are rising.
Without non-condensing greenhouse gases, water vapor and clouds would be unable to provide the feedback mechanisms that amplify the greenhouse effect. A companion study led by GISS co-author Gavin Schmidt that has been accepted for publication in the Journal of Geophysical Research shows that carbon dioxide accounts for about 20 percent of the greenhouse effect, water vapor and clouds together account for 75 percent, and minor gases and aerosols make up the remaining five percent. However, it is the 25 percent non-condensing greenhouse gas component, which includes carbon dioxide, that is the key factor in sustaining Earthâs greenhouse effect. By this accounting, carbon dioxide is responsible for 80 percent of the radiative forcing that sustains the Earthâs greenhouse effect. http://www.nasa.gov/topics/earth/features/co2-temperature.html
