Given that atmospheric CO2 has increased massively, they clearly aren't sufficiently absorbing the extra. Yes, over millions of years, and it's all being released at once. It is significant. As you've just pointed out temperatures were much higher during periods of high CO2.
Big Dave, why do you continue to spar with the Clueless??? Seriously Jekyll, "Yes, over millions of years, and it's all being released at once." is a HUGE problem. There is far more CO2 in the fossil fuels than in the atmostphere currently. Try to put something in your gun besides blanks...
Using data that's been collected since 1958 at Mauna Loa, correlated with the temperature data. That's exactly 50 years of data. As I said in reply to someone else, the Mauna Loa data correlates with global data within .26 ppm, or almost exactly. Your reply shows you haven't done even the least independent investigation of the actual evidence that's put out there in the public domain for all to access and use to make up their own minds. You're just mindlessly spewing crap.
Its all being released at once. How many years constitute 'all at once'? As the data exposes problem after problem with MMGW hoax the claims these folks make become more bizarre.
Since the start of the industrial revolution, approximately 250 years or even less. What problems have been exposed?
Not at all. Posting "lower atmosphere" temperature measurements from satellites that aren't directly capable of measuring the "lower atmosphere" didn't convince me.
No, You continue to be clueless, assuming that others will mistake it for being clever. You have as much traction as a bald tire. You need better arguments than "o, yea"
