Quote from gwb-trading:
You are once again confusing cause and effect. Long term studies have demonstrated that a rise in CO2 lags (not leads) a rise in global temperature by 800 years.
The current CO2 level and global temperature levels are well within the standard deviation of the mean over the long term on earth.
And has been pointed out many times:
There was never in the past the release of 8 billion tons per year of CO2 like there is now.
In the past the CO2 levels acted as the greenhouse gas that they are after they were released, extending and amplifying the small solar changes. There is no question about this. The forcing capability of CO2 can be determined fairly accurately via the historical records.
The fact that there may be no clear instance where CO2 STARTS the temp rise does NOT mean CO2 is a not a dominant greenhouse gas and given the conditions we see today can be expected to LEAD temp higher.
