The deadliest climate question: How many degrees cooler will that be?
Ask it now, ask it later, before breakfast and while watching “the news”. Teach the children to ask in kindy.
We know the IPCC wildly exaggerates, but pretend they’re right and it still doesn’t make any sense. Richard Lindzen, Will Happer, and William van Wijngaarden took the IPCC at its word and calculate that even if we get to Net Zero by 2050, will only make the world a tiny bit cooler, assuming they’re right (which they’re not) and assuming the rest of the world joins in (which they aren’t).
Say we stop all coal, oil and gas, redesign our energy grids, cull the cows, give up our holidays, our cars and ride bikes to work, fill the oceans with windmills, and turn our thermostats down. We spend a quadrillion dollars on a Moonshot to stuff a perfectly good fertilizer in holes underground, and instead of getting to the moon, the world is barely 0.28 degrees C cooler. That’s a half of one lousy Fahrenheit less that it would have been. This ladies and gentlemen is the best case scenario for the global action plan against the 6th mass extinction.
This is why 100,000 people in private jets meet each year in Egypt, or Doha, or Azerbaijan. (Or so they say).
The whole United States of America could go Net Zero by 2050 and it would, at best, change global temperatures by three one-hundredths of a degree, which we can’t even measure. Rounded to the nearest tenth of a degree that’s a big 0.0°C. And if the Sun does a bit more, then it’s even less.
Net Zero Averted Temperature Increase
R. Lindzen, W. Happer, and W. A. van Wijngaarden
Abstract:
Using feedback-free estimates of the warming by increased atmospheric carbon dioxide (CO2) and observed rates of increase, we estimate that if the United States (U.S.) eliminated net CO2 emissions by the year 2050, this would avert a warming of 0.0084 ◦C (0.015 ◦F), which is below our ability to accurately measure. If the entire world forced net zero CO2 emissions by the year 2050, a warming of only 0.070 ◦C (0.13 ◦F) would be averted. If one assumes that the warming is a factor of 4 larger because of positive feedbacks, as asserted by the Intergovernmental Panel on Climate Change (IPCC), the warming averted by a net zero U.S. policy would still be very small, 0.034 ◦C (0.061 ◦F). For worldwide net zero emissions by 2050 and the 4-times larger IPCC climate sensitivity, the averted warming would be 0.28 ◦C (0.50 ◦F).

And Christopher Monckton points out the cost to benefit ratio for this $2 Quadrillion dollar project is every billion dollars we spend cools the world by 20 millionths of a degree.
So let’s keep all the national science institutions that pointed out what a terrible deal this is for all our nations, and shut down the rest — NOAA, NASA, Hadley, CSIRO, NIWA, BoM, Potsdam, NRC, ARC, and while we’re at it — the ABC, BBC, the CBC because they should have asked better questions, like “how many degrees will that cool us?”
UPDATE: And a long time ago Dr David Evans calculated that if Australia got to Net Zero and the IPCC were right, we would “cool” the world by 0.0154°C.
