Bloomberg Speaks Out Against 'Carbon Tariff' - September 19, 2008 - The New York Sun

The mayor faced resistance from several Republicans on the panel who warned of higher energy costs because of a cap on carbon emissions, as well as from a fellow witness who favored a "carbon tariff."

"Any measure, including climate change legislation, that places significant additional costs on U.S. manufacturers without imposing similar costs on imports will plainly harm U.S. workers and businesses, put additional pressure on core U.S. industries, and lead to a further worsening of our trade deficit," an attorney specializing in international trade issues, Robert Lighthizer, told the committee.

Is This The Beginning of Global Cooling

Since there was global cooling from ~1940 to ~1979, this means there has been no net warming since ~1940, is spite of an ~800% increase in human emissions of carbon dioxide. This indicates that the recent warming trend was natural, and CO2 is an insignificant driver of global warming.

Furthermore, the best fit polynomial shows a strong declining trend. Are we seeing the beginning of a natural cooling cycle? YES. Further cooling, with upward and downward variability, is expected because the Pacific Decadal Oscillation (PDO) has returned to its cool phase, as announced by NASA this year.

Global warming and cooling have closely followed the phases of the PDO. The most significant pattern of PDO behavior is a shift between “warm” and “cool” phases that last 20 to 30 years. In 1905, the PDO shifted to its “warm” phase. In 1946, the PDO changed to its “cool” phase. In 1977, the PDO returned to its “warm” phase and produced the current warming. In 2007-8, the PDO turned cold again, so we can expect several decades of naturally-caused global cooling.

Some scientists are predicting that this cooling will be severe, and is a greater threat to humanity than global warming ever was. Meanwhile, politicians are still obsessing about global warming.
