Thank you for this info wendyb-NC Mar 23 #1
Thank you for your attention and kind words. n/t. NNadir Mar 23 #2

Correction: The predicted year using the quadratic for reaching 500 ppm.... NNadir Mar 25 #8
Did you happen to mean 2042 ? (I am supposing a transposition.) Thanks for checking out your spreadsheet. n/t xocetaceans Mar 25 #10
