That is exactly the point to make. We need more knowledge of the factors driving the observed changes in ice and temperatures and other manifestations of climate change. When the model does not fit the data we need to always change the model and not ignore observations and knowledge.
What is interesting is human collective reactions to observations and knowledge. I find this on common herd behaviors gives pause. Charles Mackay provided historical evidence for the peculiar behavior and beliefs of large crowds in his 1841 book, Extraordinary Popular Delusions and the Madness of Crowds. It contains an insightful account of the “Tulipomania” craze of the mid-1600s. When considering the current climate change craze, reflect upon Mackay’s observation that:
"We find that whole communities suddenly fix their minds upon one object and go mad in its pursuit; that millions of people become simultaneously impressed with one delusion, and run after it, till their attention is caught by some new folly more captivating than the first.”
Maybe the should be less concern with climate in the coming centuries and more investment in health in the next several decades, at the margin. That is withthe timeframes I proposed in earlier post. How much can we truly care about the grandchildren of our grandchildren by payng to improve their wellbeing? I believe we care about them less than about our children, and this was the case even before the trend in global temperature of the last 17 years became apparent.
