Global Warming Causes Global Cooling
The predictions have been dire.
The warnings foreboding.
Millions would die.
Coast lines would disappear as the ice caps melted raising sea levels 20 feet.
Tropical diseases would spread north and south.
Drought.
Famine.
Those few who lived would be left no recourse but to eat each other to survive in the soon to come waning days of the human species.
But then a funny thing happened on the way to our inevitable CO2 caused extinction. About ten years ago, the global average temperature stopped rising. Even though CO2 levels in the atmosphere continued to rise sharply.
This didn't deter the chicken littles of the Holy Church of Global Warming though. They tweaked their computer models - changed a few of the guesses on which they are based and suddenly a decade of changeless global temperature was perfectly normal and expected. Warming and doom would recommence soon. You just had to have faith and turn over control of your life and the world to the Church because that was the only path to salvation.
But then science did what science does (when it does what it is supposed to do). It gathered data. It studied reality. It launched a satellite called Jason.
Jason gathers data about the oceans. Empirical things like ocean wind speeds, wave heights, currents etc. Jason does this more accurately than the previous satellite called Poseidon.
What Jason - combined with a bunch of other actual empirical data is telling scientists is that we can expect a decade or two global cooling.
The priests and acolytes of the Church of Global Warming have reacted to this by predicting that as soon as soon as the cooling stops it will start warming again.
We are all doomed.

Now it’s not just the sunspots that predict a 23-year global cooling. The new Jason oceanographic satellite shows that 2007 was a “cool” La Nina year—but Jason also says something more important is at work: The much larger and more persistent Pacific Decadal Oscillation (PDO) has turned into its cool phase, telling us to expect moderately lower global temperatures until 2030 or so.
For the past century at least, global temperatures have tended to mirror the 20-to 30-year warmings and coolings of the north-central Pacific Ocean. We don’t know just why, but the pattern of the last century is clear: the earth warmed from about 1915 to1940, while the PDO was also warming (1925 to 46). The earth cooled from 1940 to 1975, while the PDO was cooling (1946 to 1977). The strong global warming from 1976 to 1998 was accompanied by a strong and almost-constant warming of the north-central Pacific. Ancient tree rings in Baja California and Mexico show there have been 11 such PDO shifts since 1650, averaging 23 years on length.
