The author should stick to the argument that the cap and trade
does nothing to effect climate change. Picking a time period showing
relative stability in one layer is disingenious imo, especially when particulate
pollutants (which have increased) in that layer might play a major role in the convenient time period chosen.

Actually this is wrong.

In the 1970s concerned environmentalists like Stephen Schneider of the National Center for Atmospheric Research in Boulder, Colorado feared a return to another ice age due to manmade atmospheric pollution blocking out the sun.

Since about 1940 the global climate did in fact appear to be cooling. Then a funny thing happened-- sometime in the late 1970s temperature declines slowed to a halt and ground-based recording stations during the 1980s and 1990s began reading small but steady increases in near-surface temperatures. Fears of "global cooling" then changed suddenly to "global warming"
