That was not proven as I've talked about in another thread.The fact is, the planet is warming, and we know for a fact that human beings are doing things that can be shown scientifically to create conditions that accelerate that warming.
How much CO2 we put into atmosphere vs how much nature puts: ~3.76%
How much of CO2 is in the atmosphere: 0.039%
How much CO2 humans add to the atmosphere:.. 0.0014664%

Not only that, but:
CO2 lags an average of about 800 years behind the temperature changes-- confirming that CO2 is not the cause of the temperature increases. One thing is certain-- earth's climate has been warming and cooling on it's own for at least the last 400,000 years, as the data below show. At year 18,000 and counting in our current interglacial vacation from the Ice Age, we may be due-- some say overdue-- for return to another icehouse climate!
