(lead scientist of NOAA's Global Greenhouse Gas Reference Network):
Based on the best historical data that we have available CO2 is probably increasing at a rate at of least 100 times faster than at any time in the last 800,000 years.
I want to make sure that this is an accurate statement.
Have there been any faster changes over a similar timespan in the history of life?
Does science validate this statement: "It is virtually certain that there are no natural processes that could plausibly account for an average annual CO2 increase of 1.42 PPM lasting 70 years (1950 to present) at any time in the last 40 million years"
Here is the 40 million year data graph
