MacRae: Is This The Beginning of Global Cooling?

Excerpts from an article by Allan MacRae at ICECAP:

Since just January 2007, the world has cooled so much that ALL the global warming over the past three decades has disappeared! This is confirmed by a plot of actual global average temperatures from the best available source, weather satellite data that shows there has been NO net global warming since the satellites were first launched in 1979.
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.

(...)

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.

Cold kills more effectively than heat does. A person exposed to the elements can tolerate a considerable amount of heat but will suffer from hypothermia when temperatures drop by a few degrees. There is a type of hypothermia that occurs in doctors' offices when a person is asked to don the gown and is then left lying or sitting on the examination table. Even at room temperature, a patient's core temperature will fall.

The British health authorities estimated that if the average temperature rose by 2 or 3 degrees, some 2,000 more heat related deaths would occur. On the flip side, they estimated that about 20,000 fewer deaths from cold would occur.

Plants, especially food crops, will not do well in a colder world. Elevated CO2 may make them more cold resistant, but harvests will decline.

Warm is far preferable to cold. Whether that current cooling trend will continue is still pretty much in the conjecture column. I don't think anyone can say for sure. The best guess at this point is that it will and for a couple of decades.

For what its worth, we all know that if it does get colder, it will still be our fault. We are almighty and we have taken over control of the climate.
