Lindzen goes on to say...
“The earth is always warming or cooling by as much as a few tenths of a degree a year; periods of constant average temperatures are rare,” Lindzen says. “The current alarm rests on the false assumption not only that we live in a perfect world, temperaturewise, but also that our warming forecasts for the year 2040 are somehow more reliable than the weatherman’s forecast for next week.”
His most important point—after dissembling models that show seas rising—is that temperatures should have risen much more dramatically if global warming from CO2 was really the only mechanism at work. “Average temperatures rose only about 0.6 degrees since the beginning of the industrial era, and the change hasn’t been uniform—warming has largely occurred during the periods from 1919 to 1940 and from 1976 to 1998, with cooling in between. Researchers have been unable to explain this discrepancy,” he points out.

The debate is over. No more posts on this thread.
Lindzen's statement is a gloss. Sulfate aerosol forcing explains the majority of the cooling. A small increase in solar output is cited for part of the warming (anthropogenic GHGs for the other part) for the early century warming.
