[added comments] While carbon dioxide is a “greenhouse” gas and it does absorb energy in some infrared wavelength bands, many scientists will argue that its affect on average global temperatures have been considerably exaggerated by the proponents of catastrophic anthropogenic global warming. In order to derive effects extreme enough to be considered catastrophic, they have had to rely on strong positive feedback resulting in much larger effects than CO2 could produce without any feedbacks. Many prestigious scientists disagree with that and some even suspect the feedback is not only much less than estimated, but may even be negative.
One must always consider that contrary to that which is frequently stated by climate activists/alarmists, the debate is never over in science.
Burnett: You coauthored a book titled Lukewarming: The New Climate Science that Changes Everything. What is the thesis of the book?
Michaels: Global warming is often presented as one of two alternative visions: left unattended, it will bring about an unmitigated disaster with tremendous consequences to humanity and the planet; or there is really “no such thing”—meaning little to no warming and little to no influence of human greenhouse-gas emissions on climate.

A newly published paper, titled “Evaluating the Performance of Past Climate Model Projections,” mistakenly claims climate models have been remarkably accurate predicting future temperatures. The paper is receiving substantial media attention, but we urge caution before blindly accepting the paper’s assertions.
“So, the long and short of it is that the prediction that the bear numbers would decline by two thirds failed. Not only did the bears not decline, but the global population number rose by at least 16 percent, perhaps more.”

Susan J. Crockford: I live in Victoria, British Columbia, and I specialize in animals from the late Pleistocene, so probably the last fifteen to twenty thousand years. I have a contract company called Pacific Identifications Inc. We identify animal bones from archaeological projects and also from biological research: stomach contents, fecal samples, that kind of thing. That’s primarily how I get my income. And then, I am also a former adjunct professor at the University of Victoria—I had held that position since 2004 but in 2019, it was not renewed.
My primary interest—my overall interest—is evolution. That, for me, really informs everything. It’s the big picture. Evolution is the big idea that drives all my interest. For example, the interesting thing is that a deer bone from 8000 years ago looks like one living today, and so, there is continuity.
But there are also distinctions—when you get species differences, those are apparent. I became interested in polar bears when I was working on the topic leading up to my PhD dissertation. I was looking at the speciation process that turns a wolf into a dog (what we also call domestication). While trying to unravel what biological process drives that transformation, the wild species that I looked at to compare it to was the brown bear to polar bear transformation. So, I’ve been looking at the Continue reading “A conversation with Susan J. Crockford—for Association des climato-réalistes”
Five Impossible-to-believe topics fed to us by the alarmists: A 2019 report: Climate is in Crisis, 100% renewable electricity is possible, Hurricane Dorian was made stronger by our use of fossil fuels, Hurricane Michael was Category 5 at landfall, and human-caused CO2-fueled global warming is a coming catastrophe. This post summarizes my November 2019 presentation to the Cruces Atmospheric Sciences Forum, CASF.
THE CLIMATE CRISIS TOWN HALL
On 4 Sep 2019 CNN presented a televised town hall meeting where 2020 Democrat presidential candidates discussed a purported human-caused, CO2-fueled climate crisis; Inside Climate News reported on the event. I focus on three elements of that report, encapsulated in these quotes:
“There was none of the debate over science that has dominated U.S. political discussions and strangled action in recent years.”
