If you're going to note his credentials as a physist & Caltech president, you should also note that he was also employed by BP as the oil and gas company’s Chief Scientist from 2004 and 2009.
Remember, one of the oldest ruse of climate-change deniers is to equate weather and climate.
So how is that different from veing a full time job in climate change as a scientist or policy maker?
Do you believe that Koonin wants a climate catastrophe?
If a person could be so monumentally blindsided to ignore a threat that will not only harm themselves, but everyone they know and care about, then could not others be too, e.g. Climate scientists?
Another question;
Accepting Climate Change as presented by the IPCC, how do we resolve the problem of the major oil producing states like Russia and Saudi Arabia refusing to give up the oil wealth which allows them to exist as they do, and the developing world states from consuming it? Green conversions are not feasible for large segments of the world population in anu useful time frame.
The net zero policies being advocated by the G7 nations are very expensive and handwave away big problems with "batteries will get cheaper, and the tech will improve" but they fail hard if thar doesn't turn out.
If we are really concerned about CO2 driven climate change the best solution is next gen nuclear power and mitigation strategies. Make electricity so cheap that no one will want fossil fuels if they can avoid it. Yes, they just started talking about nuclear power, but it's late. James Hansen was talking about it 20 years ago, it's not a surprise.
People commonly downvote to signal disagreement, and that's not discouraged by the guidelines. There is, however, a rule against complaining about votes.
