@pschwede Depends on what part you need educzting on. There are really 2 points you might not be informed about which i could help point you to some info on..

1) if you deny that atmospheric CO2 levels have a direct and significant impact on global temperatures

2) if you deny that CO2 levels are increasing at rates never seen historicaly

or 3) If you deny that the rise that we are seeing is due to human injection of Co2 rather than other sources.

Of those three points which are the ones you need info on?
