Data From Two Separate Studies Confirm No Link Between CO2 And Temps

earth 150m years agoGerman climatologist Professor Dr. Horst-Joachim Lüdecke recently took data from two independent studies and superimposed them.

The result shows the long-claimed atmospheric CO2-global temperature correlation doesn’t exist.

The first data set was global temperature anomaly going back 600 million years, taken from the results of a paper by Came and Veizer, appearing in Nature (2007) and plotted below (blue):

The second data set was of atmospheric CO2 going back 600 million years, taken from a published study by Berner (2003), also appearing in Nature. These data are plotted in the above chart in blue.

No correlation

The plots were combined in the above chart to see how well they correlated, if at all. The result: no correlation.

For example, as the chart shows, 150 million years ago the atmospheric CO2 concentration was over 2,000 ppm, which is five times today’s atmospheric concentration of 410 ppm – a level that some climate scientists say is already “dangerously high.”

Yet, the global temperature 150 million years ago was more than 2°C below the long-term mean.

450 million years ago the relationship was even far more on its head: atmospheric CO2 concentrations were more than 10 times today’s level, yet the global temperature was a frigid 3.5°C below the mean!

“There’s no correlation between earth temperature and CO2,” Prof. Lüdecke concludes, observing recorded data.

    Just last week on Wenesday our area was hit with a Thunderstorm that dumped lots of Rain so much rain it contaminated our towns water Supply we were using Bottled water or having to boils the water for few days afterwords

    Some very fine modellers will likely correct it for the sake of the planet and humanity so the two correlate exactly. Then the corrected graph can go viral through the interconnected green groups, as the original is pilloried as the scientific fraud that it clearly is.

    Yes. No doubt I am prone to spout sarcasm. The warming cult does that to me.

    Not really a surprise. Weather is cyclic, always has been and will be, even the graph above shows that very thing with variations. It is typical really that year in year out there are variations. Sadly this will be dismissed by LCMs (Leftists/Communists/Marxists) in their quest for world domination. Maybe they should be very careful what they wish for.

    But as always the NYT’s and CNN like the Liberal Democrats will ignore the whole thing
