A few serious scientists: Richard Lindzen, Will Happer, Judith Curry, John Clauser, Ivar Giaever

Dear Tyler,

There are, in fact, a few serious scientists who take issue with that claim, and you should meet some of them. My response is in three parts, plus information about a class I teach and a call for a proper debate:

Part I: Over 9,000 scientists with PhDs take issue with that claim

First, a group of volunteer scientists put together a list of over 31,000 scientists who signed a petition asking for people who agreed with the statement:

There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gases is causing, or will, in the foreseeable future, cause catastrophic heating of the earth’s atmosphere and destruction of the earth’s climate. Moreover, there is substantial evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of earth.

More than 9,000 people with PhDs signed that petition. Many more are working scientists with master’s degrees. Feel free to discount those numbers by some amount if you wish, but those signatures are just a sample of a much larger number. Other lists include …

Of course, numbers of “believers” don’t determine scientific outcomes, consensus is not how science is done, but I’m responding here to a specific claim and want to introduce you to some people you don’t know.

Part II: A curated list of serious scientists with PhDs who take issue with that claim

Total so far: 173

These people with Ph.Ds have all gone on record saying that CO2 is beneficial and is not causing any degree of worrying climate change, even in the extreme limit that humans could produce. I have validated their credentials. Some of them probably signed the above petition. Those still alive (most) are actively helping people learn that today’s climate science is mostly propaganda, lies, and bad models.

I'm leaving out working scientists …

  • with master's degrees (too many to count).

  • with MDs (also too many).

  • who can't afford to go on the record in fear of losing their jobs (far too many).

  • who asked to be left off for professional reasons but said they support the idea.

To be honest, there are many more PhD’d scientists than I can document properly. In case you think MIT PhDs get extra credit, they are in blue (with apologies to those from Princeton, Cal Tech, and Stanford) and Nobel laureates in red

Those who want to be added — send me your name, department and university that issued your Ph.D.

You can find plenty of criticism of most of these people online. These are the scientists old enough or brave enough not to be threatened. Calling them names does not delete the importance of their contributions to science. If you don’t know who Giordano Bruno was, that’s exactly my point. Science has a serious credibility problem.

The risk of net-zero

Many of us agree with the statement that going to net-zero via renewables is a threat to civilization as we know it because the math of net-zero doesn’t work, both for economic and ecological reasons. I don’t speak for everyone, and I only have a master’s degree, but I believe most of us agree that a gradual, market-based transition to nuclear energy with no wind, minimal solar, minimal battery storage, minimal regulation, and minimal government subsidies is the best energy policy. Intermittent power makes everyone poorer, especially in Africa. No one should have to suffer from energy poverty. Governments should support the development of fossil-fuel-based grids to provide affordable, reliable baseload power and focus environmental resources on local issues like pollution, spills, cleanups, prevention, etc. Governments should support efforts to build nuclear power plants the market wants, not through subsidies but through reduced regulation and stronger international agreements.

No country, no state, no city, no company, no organization should have a climate policy, because humans can’t affect the climate.

Part III: For further research

There is much more. There are papers, blogs, newsletters, organizations, books, videos, and YouTube channels all dedicated to getting the word out that scientifically, CO2 is not a driver of climate, we are currently in a CO2 famine, and more would be better. CO2 is plant food. It is not pollution. Greenhouses pump in CO2 to about 1,200 PPM to help plants grow. For 200 million years, from 550 million to 350 million years ago, CO2 was in the 2,000 to 8,000 PPM range (up to 20 times higher than today), the earth was generally (but not always) warmer than today, plants exploded, and life flourished. Even back then, CO2 drove plant growth but not the climate.

Climate science master class with David Siegel

The class is now evergreen — you can join any time. See the class page for details and registration.

An important climate debate

We would be happy if you could help arrange a serious, long-format debate on the science. We are eager to debate. I think you’ll find precious few mainstream climate scientists interested in debate. The IPCC certainly isn’t.

So, Tyler, if you’d like to have a conversation with any of these people, let me know and I’ll set it up. All of us could read and learn more widely on many topics, as you’ve explained so many times. I’d love to help you do that.

Sincerely,

David Siegel
