” …you want to call the current long term global warming crisis an ‘episode’.”

Actually, I don’t want to call it anything except what it is: global warming since the last “little ice age”, 200 years ago.
Before that, the earth was relatively warmer and entered a cooling period. And “the issue” is NOT “the long term accumulation of greenhouse gasses”, but whether the theory that these gasses are causing “greenhouse” global warming is correct.

I’m not a “believer” or a “non-believer”. I do believe the “tight correlation” you point out is not necessarily one of cause-and effect but MAY be coincidental.

Fact is there are credible theories explaining global warming and cooling that account for the current warming cycle having nothing to do with “greenhouse gasses”.

Dr. Hansen has simply been open and honest about the facts, not every weather change is due to global warming. Further, he has never relied on episodic evidence to prove that we are now in a long term crisis situation. That is, unless you want to call the current long term global warming crisis an ‘episode’.

Well, the climate is always variable, but the issue is the long term accumulation of greenhouse gases, and the continued increase in the generation of them. This is unprecedented in the history of life on earth. We know where these gases are coming from, mostly carbon dioxide. And, the effect on the overall average temperature of the atmosphere is as one would expect due to the greenhouse effect. The correlation is tight.

The article above: “..Dr. James Hansen, the U.S. expert on global climate change.”

Dr. Hanson has become a prisoner of his reputation, as did the Catholic theologians who in the seventeenth century ever more stridently attacked Gallileo’s contrary understanding of our universe.

For example: he has publicly asserted that last summer’s heat wave in Texas was “an outlier” of global warming.

Scientists (and anybody else, for that matter) are on shaky ground when they rely on episodic evedence to support broad conclusions. Furthermore, Dr. Hanson’s defensive bias is revealed by his neglect of contrary episodic evidence; namely, the brtally cold winters across much of Europe in the same year.

What if climate changes are occurring today, as they have in the past, substantially independently of the activities of mankind? The history of the earth’s temperature changes over eaons has been one of continuous change. The historical evidence for this is at least as strong as currently “politically correct” models.

Furthermore, not all current models are politically correct, e.g., they explian “global warming” in terms of naturally occurring (and recurring) change.

It may be that the relatively slow change since the last “little ice age” about 200 years ago has conditioned us to believe recent acceleration in temperature is caused by accelerating human activity, rather than merely coincident with it.
