you seem to mistaking imply or actually believe co2 can only warm. you seem to be the only person who does not understand the properties of a greenhouse gas.
Tell us the truth do you realize co2 can also act so as to cause cooling?
We live in a complex system with negative feedbacks... its far more complicated than say oh we just added x greenhouse gas to the system so this must
happen.
you have been posing this same silly question for years and it never wins for you.
no one here disputes the definition or properties of greenhouse gases except you.
As NASA experiments proved... co2 warms and co2 cools.
the question is whether mans co2 production increases the amount of co2 in the atmosphere and if it does... does that co2 increase cause warming.
you have to remember the earth has co2 sinks and it can off gas.
you have to remember historical co2 levels have always followed change in temperature.
So co2 maybe simple be like water vapor...as temps go up the atmosphere can hold more co2. then when ocean cools and air cools the co2 levels go down.
We live in a complex system with negative feedbacks... its far more complicated than say oh we just added x greenhouse gas to the system so this must happen.
I'm still waiting for evidence that CO2 has somehow changed it's physical properties and is now NOT a greenhouse gas.
Literally all one needs to know is that CO2 is a GHG. This fact is beyond rational doubt.
So the deniers and skeptics look pretty dumb.
Period, end of discussion.
