A Challenge to the "Settled Science" Meme

I've read at least a dozen books on the climate issue in the last month. This is the best. Koonin is not just another "skeptic." His approach to the matter rises above "controversy" and depends on evidence. Yet, he acknowledges where the panic is coming from.

A lecture by Koonin covers much of the key material and provides color versions of the slides, which are black and white in the book. Another interview, without the slides, is here.

In reading IPCC reports, it's evident that the "summaries" don't "summarize" the actual science. The ultimate summary, the speech by the head of the IPCC, bristles with inaccuracies and has no message beyond panic. As a senior climate scientist, Koonin provides some startling stories of the "blow-back" he gets by simply asking for an independent review of IPCC conclusions. In fact, there was a brief attempt to cripple such a review by denying federal funds to any study that challenged the consensus on the climate emergency. In fact, the first finding of such a challenge would be that there is no such consensus.

Proposed "solutions" to the "emergency" lack credibility. The media brings in climate alarms as part of their standard format, which assumes (without a shred of evidence) that every weather extreme is a sign of climate change and a sign things will be getting worse "unless we do something soon". Koonin points out that the biggest objection to emergency solutions is that climate problems (if they are real) are less important than global poverty - particularly energy poverty. He also provides a realistic "net zero" date as 2075. Even if that were achieved, C02 concentrations would continue to warm the planet for centuries.

He did tell me a few things I didn't know about C02. At a certain point, C02 will reach its maximum blocking effect. In other words, C02 "forcing" does not rise forever. The takeaway is that this maximum will be hit no matter what we do.

There is also a lesson on interpreting headlines that read "Hottest (coldest) day on record." Besides being simply part of the alarmist rhetoric, there are statistical errors behind the graphs that purport to show trends in temperature. If there is a trend, it is for temperatures to become "milder," with no real trend in the high but a trend in the low, meaning "less cold." "Less cold" doesn't get the headlines that "hotter" gets, nor do we see headlines that say "Today's Heatwave Not Unusual."

For those who really do want to get to the bottom of these issues, "Unsettled" is a long, cool drink of solid science. Koonin has 45 years of experience in the field at the most senior levels.  I was particularly impressed with his treatment of climate models, which added to my understanding, especially when it comes to trusting the models to provide information that would support the multi-trillion dollar investments proposed to overhaul society.
