These charts show more of a correlation. The other chart invites far more questions than answers. Also, would like to see if events unrelated to human activity during the past 60 years have increased the CO2.Quote:

Paul - whether you realize it or not, you just unwittingly destroyed your own argument!!Quote:

Additionally, with the graph you posted in #2115 from NASA, why is it that they only published data in a graph that goes back 800,000 years, when they obviously have data that goes back much further? Are they trying to fool the public?
NOAA even admits this point:
"The atmospheric burden of CO2 is now comparable to where it was during the Mid-Pliocene Warm Period around 3.6 million years ago, when concentrations of carbon dioxide ranged from about 380 to 450 parts per million. During that time sea level was about 78 feet higher than today, the average temperature was 7 degrees Fahrenheit higher than in pre-industrial times, and studies indicate large forests occupied areas of the Arctic that are now tundra."

And why are they only looking at data from Arctic ice cores? Antarctic ice core data tells a different story. Why not tell the complete story?
"During this period, CO2 and temperatures are closely correlated, which means they rise and fall together. However, based on Antarctic ice core data, changes in CO2 follow changes in temperatures by about 600 to 1000 years, as illustrated in Figure 1 below. This has led some to conclude that CO2 simply cannot be responsible for current global warming."

If we had these same CO2 levels in the Mid-Pliocene age and sea levels were 70 feet higher, the folks in Miami may be in a lot of trouble.
Also, from your link in explaining the second graph shown:
Quote:
While the orbital cycles triggered the initial warming, overall, more than 90% of the glacial-interglacial warming occurred after that atmospheric CO2 increase (Figure 2).

Also after the the change in orbital cycles. Perhaps the cycles were the cause of the increased CO2 and temperature? Again, both increased likely do to a much more impactful catalyst?Quote:

I will never believe that we have anything approaching accurate world-wide temperature data from 1000, 10,000, 100,000, 1M years ago using ice core samples and tree ring data from a proportionally small area of the Earth, and then extrapolating that data onto the rest of the world. That method would never work or be accepted in any other field. There is no way the historic temperature data is anywhere near accurate. Without historic temperature data, we have nothing to compare to recent trends. And how far back do we truly have accurate world-wide temperature data? 50 years? How long have we been able to accurately measure temperatures in all the oceans, polar regions and other hostile places around the world that make up more than 75% of the planet?
I would argue the same holds true for historic co2 levels as well.
Global warming has been torching Cincinnati all week and I'm tired of it!
Ohhhh, see. That’s “weather” and not “Climate”.Quote:

An excellent piece in the WSJ, written by one of my favorite economics writers, Greg Ip. Link: https://www.wsj.com/articles/ipcc-cl...ts_pos1&page=1.
I hope any Muskies in Ida's path have been able to evacuate.
Stay safe down there.
