Dr. Mike Hulme says scientists and activists are exaggerating the threat for political ends

By Phoebe Smith, Public, Feb. 25, 2024

Politicians and activists alike have warned of a looming climate catastrophe for decades. “Biden urged to declare climate change a national emergency,” reported NBC last year. “Climate Changes Threatens Every Facet of U.S. Society, Federal Report Warns,” announced Scientific American.

Cambridge University climate scientist Mike Hulme disagrees. “Declaring a climate emergency has a chilling effect on politics,” he tells Public. “It suggests there isn’t time for normal, necessary democratic process.”

Climate activists may dismiss Hulme as a “climate denier,” but he agrees the planet is warming due to human activities and specifically says we should prepare for more heat waves. … Read more

Over recent and deep geological time, when temperature and carbon dioxide are correlated, temperature is the ‘control knob’ of CO2, not vice-versa. Otherwise there is almost no correlation

By Paul MacRae, Climate Realists of British Columbia, Jan. 31, 2024

The basic theory underlying orthodox climate science is that the global temperature is highly sensitive to changes in carbon-dioxide levels. This is sometimes called the “control-knob” theory.¹ If CO2 increases, so does temperature. If CO2 falls, so does temperature, more or less in lock-step—CO2 is the “control knob” of temperature.

And since we are in a “warming” world, and because CO2 levels are also going up—in other words, because temperature and CO2 levels appear to be correlated—orthodox climate science accepts that they are correlated—in fact, strongly correlated, as we’ll see.… Read more

With a bit of research, Victoria radio host could educate local listeners on the follies of the Liberal government’s ‘anti-growth’ policies

By Paul MacRae, Climate Realists of British Columbia, January 28, 2024

A local Victoria, B.C., radio talk-show host had some doubts about a recent caller’s argument that Canadian Maurice Strong was behind the environmental-crisis movement and, by implication, behind the “climate crisis” movement as well.

In other words, the caller was suggesting that these movements are not based on solid “science,” as we’re told, but on an anti-growth ideology rooted in Strong’s “neo-Malthusian” thinking—the view that modern civilization cannot survive affluence and will soon run out of resources, although this view has been largely disproved by facts.… Read more

Claims that ‘the science has spoken’ and ‘the science is settled’ are based on the false idea that climate scientists follow the same scientific standards as traditional scientists. They don’t

By Paul MacRae, Climate Realists of B.C., January 22, 2024

Those who dare to question or criticize the apocalyptic claims of the Intergovernmental Panel on Climate Change (IPCC) (“if we keep adding carbon to the atmosphere we’re all gonna fry,” basically) are told “the science is settled” or “the science has spoken.”

We’re told “the science” is the product of a “consensus” of more than 2,000 climate scientists who contribute to the IPCC’s reports; and we’re told this “consensus” is not to be questioned by non-scientists or even scientists from other disciplines because, again, the science is “settled.”… Read more

A Norwegian government study dares to admit that computer models can’t tell us if warming is human-caused or natural

By Holman w. Jenkins, Jr., Wall Street Journal, Nov. 4, 2023

If this column has ever plagiarized itself, it’s by repeating the phrase “evidence of warming is not evidence of what causes warming.” A paper published by the Norwegian government’s statistical agency, written by two of its retired experts, touching on this very subject has called forth so many shrieked accusations of climate apostasy that you know it must be interesting.

The authors ask a simple question: Are computerized climate simulations a sufficient basis for attributing observed warming to human CO2?… Read more

Money wasted on solar and other ‘renewable’ energies could have been used to solve the housing crisis

By Michael Blair, Substack, Dec. 11, 2023

At the current state of the technology, about 80% of energy used to generate electricity through solar panels is lost to heat. The other 20% is captured in the form of electricity and converted to work. We can estimate how much quite readily.

The International Energy Agency (IEA) says 179 Terawatt hours of electricity were generated from solar last year. Presumably that is ~20% of the energy reaching the solar panels that created that power.… Read more

Meeting the Paris climate promises would create benefits worth $4.5-trillion (in 2023 dollars), at an annual cost of $27-trillion. Each dollar spent will avoid 17 cents worth of climate damage.

By Bjorn Lomborg, Wall Street Journal, Nov. 30, 2023

World leaders have gathered in Dubai for another climate conference, which will no doubt yield heady promises along the lines of the 2015 Paris climate agreement to keep the global temperature’s rise “well below” 2 degrees Celsius and pursue efforts to limit it to 1.5 degrees. But they’d be wiser not to. New research shows how extravagant climate promises are far more wasteful than useful.… Read more
