Midcentury CO2 levels might be as high as they've ever been in 50 million years from www.zmescience.com
The Global Monitoring Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites [Conway, 1994] The horizontal red bar shows the forecast uncertainty range of ± 0.56 ppm.
