CO2 is a TRACE component of our atmosphere. Even a DOUBLING of CO2 still makes it a TRACE component.
We have endured the coldest two winters, back to back in 30 years in the US and in 42 years in China. 2005 saw the coldest winter in recorded history in eastern Europe and Russia, even colder than the famous winter of 1941-1942 that stopped Hitler in his tracks.
C02 is about 4% of the atmosphere.
Global warming is a myth.
Let's hope you're right as it pertains to right now
But since we know that the climate has changed many times, sometimes getting warmer, sometimes getting colder, suggesting that global warming is a myth is simply incorrect
As to what is causing the warming trend that is being reported now?
The case is still out on that one, I think.
