Climate thinking that smells right to me...
Take a look at this graph, from the work of Dr Syun-Ichi Akasofu, of the International Arctic Research Center, University of Alaska Fairbanks. [Link]
I spend a lot of time wandering the realm of climate studies. So I'm not ignorant. And Dr Akasofu's graph makes a heap of sense to me. That dashed line is the general warming trend, about 1°C per 100 years, as the earth recovers from the Little Ice Age, which hit its low point about 1800.
The observed climate forms a sine wave superimposed on that warming trend. The box shows the time period with good observational data being considered. Note the darker red line within the box. That follows the increasing temperature trend as the wave leaves the low point of the 1970's, and rises during the 1980's and early 90's.
What happened in that period? Computer climate models were invented. And baked into all the models was the assumption that increasing CO2 would result in warming. And those models all matched reality--the world really was warming at that time! And they all predicted that the globe would continue to warm, since CO2 was continuing to increase. The pink area labeled IPCC (The UN International Panel on Climate Change) can be considered the combined predictions of all the models.The models have come to be treated as if they are the climate themselves, and nature is just a dullard that isn't conforming very well to the software of reality.
Once it dawned on the world's leftists (which includes most scientists) that this predicted warming was a perfect excuse to seize power and wealth, and crush freedom and democracy, warmist scientists were showered with grants, tenures, prestige, and trips to luxurious climate conferences in posh venues. So, surprise surprise, scientists produced ever more of the kind of research that was being rewarded. And any dissenters were attacked and ostracized, so they mostly kept their heads below the parapets.
BUT, the sinusoidal wave always turns back. Sometime in the 1990's the climate leveled off. This was assumed at first to be just a random fluctuation. But during the "noughties" (is that a word?) the leveling-off continued, with maybe some signs of cooling, and by, say, 2010, was becoming too obvious to ignore. And people like me made our popcorn, and settled back in our seats to watch the commies squirm and make excuses and lash-out in their desperation.
One of the many reasons that Akasofu's works smells right to me is that I was there back in the 1970's, when predictions of an imminent ice age were being made. And the same power-grabs were being attempted, although they didn't have time to really take effect before the wave headed upwards.
UPDATE: Here's a very interesting piece on the Little Ice Age. But I was amused by the fear evidenced in this author's intro...
Note to general public:
My position on the current global warming is the same as the overwhelming majority of international climate scientists: the current rate of global warming is unprecedented and is being caused by humans. In no way can my summary of the research regarding the impact of regional climate change on the Viking civilization and Europe during the Little Ice Age be used to "prove" the current global warming is due to a natural cycle...
Of course his work, while not proving anything, is a strong indicator that current warming is in fact natural. The same is true of the Medieval Warm Period. That's why the warmists have used foul deceits to try to make those variations go away.Posted by John Weidner at June 23, 2013 7:55 AM
