The realization that average temperatures have not increased for over a decade is adding credence to the argument that man’s influence on our climate is overstated, and that there are natural cycles over which we have no control that dictate the planet’s temperature.
The fact is that the warmest year recorded globally was in 1998—11 years ago—and climate models did not forecast it, even though man-made carbon dioxide has continued to rise.
This from BBC News:
According to research conducted by Professor Don Easterbrook from Western Washington University last November, the oceans and global temperatures are correlated.
The oceans, he says, have a cycle in which they warm and cool cyclically. The most important one is the Pacific decadal oscillation (PDO).
For much of the 1980s and 1990s, it was in a positive cycle, that means warmer than average. And observations have revealed that global temperatures were warm too.
But in the last few years it has been losing its warmth and has recently started to cool down.
These cycles in the past have lasted for nearly 30 years.”
So is this conclusive evidence that the notion that man is primarily responsible for global warming is wrongheaded? Perhaps not, but it does cast doubt on the theory. Enough doubt that our governments should not rush into spending billions on trying to stop/delay something that is probably inevitable.
Professor Easterbrook says: “The PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually assuring us of about 30 years of global cooling.”
Should Professor Easterbrook’s prediction hold for, say, the next ten years, I can foresee the whole issue of manmade global warming being pushed onto a back burner by cash strapped governments struggling to haul their economies out of deficits and their nations out of crippling debt exacerbated by the last year’s financial crisis.
By that time we will have had some twenty years of cool temperatures, and the lib-left will have had to find some other cause célèbre to fund the massive income redistribution they are trying to slip past us.
