The correlation between CO2 emissions and «global warming» suddenly vanished.

However, as I understand it what is currently the mainstream view is that what explains the transition from early 20th century warming to the flat period between is the resumption of industrial production and thus of reflective aerosols (predominantly sulfates), and that likewise, it was the passage in the early seventies of laws requiring cleaner emissions that reduced reflective aerosols.

Among those who are seeking a new direction on energy and emissions, the discussion appears to remain locked where it's been for years — over the balance between treating global warming like a 20th - century pollution problem and a 21st - century technology challenge.

Rate of percentage annual growth for carbon dioxide has certainly increased since the beginning of the 21st century, but this should result in a significant change in the rate of warming any more quickly than the differences between emission scenarios would, and there (according to the models) the differences aren't significant for the first thirty - some years but progressively become more pronounced from then on — given the cummulative effects of accumulated carbon dioxide.

While, in theory, human activities have the potential to result in net cooling, a concern about 25 years ago, the current balance between greenhouse gas emissions and the emissions of particulates and particulate - formers is such that essentially all of today's concern is about net warming.

In short, since 1997 there has been neither any global warming nor any enhancement of the greenhouse effect to cause it in the first place, and with no possible correlation between increased CO2 emissions and global warming; there is simply no scientific basis for the for the ludicrous concept that fossil fuel derived CO2 emissions are or could even cause catastrophic global warming!
