This was calculated from the same sources that gave us rising temperatures for a decade and flat temperatures for the past decade. That total gain was perhaps the same size. So what is everyone waiting for? It takes two decades to warm the northern hemisphere 0.7 degrees and perhaps six months to reverse it totally. That is not a big story. Are they waiting for confirmation? Try looking outside your window.
What we know of climate change history has always said the same thing. The warming is slow and gradual while the chilling is abrupt. This looks like a chill out and it is likely good for another year or more. The next set of numbers should show even more decline.
The mechanism for all this is becoming a lot clearer. Incoming heat is unevenly distributed between the Northern and Southern Hemispheres through oscillations focused on the Pacific which is half the planet. When surplus heat is pumped into the north across the equator the PDO shifts it north and if necessary discharges the surplus into the Arctic as occurred in 2007. When that occurs the elastic band snaps back and we catch a surge of cold weather. Sound familiar?
The problem of course is that the effects of CO2 are impossible to separate out from this type of decadal cycle. We certainly do not have the centuries of accurate Arctic weather information to compare. Maybe we should be excited because we melted some sea ice this time around. Or more likely, we should be disappointed and get serious about planting trees in the Sahara.
I am trying to say that this snap back of global temperatures is a hell of a story and absolutely no one is picking up on it. What are they thinking? Their only evidence just strode out the door. Isn’t anyone brave enough to stand up and simply say that the party is over?
I want to see a credible climate scientist stand up and say this reversal is a temporary move and that the fundamentals are good for a swift return to global warming. I used to sell stock in gold mines too. Of course they are all hiding, depending on how bravely they supported the CO2 theory.
I suspect that the rest of the crowd, who are too lazy to keep a close eye on the data will keep talking global warming while we continue to have a good old fashioned multi blizzard winter well into March. How do you like it so far?
I know that this is just one winter and that last winter was the actual beginning of a cold cycle, but this really feels like we are back in the fifties for foul weather. I was just a kid then, but that sort of foul abated into the sixties and had almost disappeared running into the nineties and most recently. It was apt that they measured sea ice thickness in 1959 and likely caught the maxima. 2007 gave us a pretty good minimum.
