A new paper on climate change has been published that concludes doubling atmospheric CO2 from 400 to 800 ppm will result in far less warming than has been previously predicted.
In plain terms, the work investigates the rise in temperature at three levels in the atmosphere as the Earth adjusts its thermal balance from heat trapped by so-called ‘greenhouse’ gases. Using a watts per square metre formulation (3.7 W/m2), it is commonly held by the Intergovernmental Panel on Climate Change that a doubling of CO2 will lead to a rise in temperature at the TOA of 1.2°C. The scientists have reduced this number to 2.26 W/m2, a 39% reduction down to a temperature rise of 0.72°C.
So after 40 years of fear mongering and flushing trillions of dollars down the climate change toilet the latest estimate is 0.72 degrees C of warming which is almost exactly what the Schwarzschild equation predicted in 1906.
If atmospheric concentrations of CO2 double form the current 400ppm to 800ppm we can expect to see less than 1 degree of warming. This much warming will be beneficial.
The science really is settled. It was settled back in 1906 but we have been denying the science since the 1980s. The nature of science has changed. In 1906 science was done in pursuit of knowledge. In 2023 science is done in pursuit of profits. There was money to be made if you were willing to conclude that CO2 would destroy the planet. Far too many “scientists” were willing to do so by imagining positive feedbacks that would amplify the warming from CO2. These positive feedbacks do not exist. There is no climate crisis.
This is not science it is politics and propaganda and it is not limited to climate science. Climate science is by far the most egregious example of how money has corrupted science but it is not the only example. Governments and corporations routinely pay scientists to arrive at a pre-determined conclusion. That is why so much science now is found to be fraudulent.
Richard Horton, editor-in-chief of the Lancet, stated that perhaps as much as 50% of all published research is fraudulent
A good rule to follow is if the news article starts with “scientists say” or “experts say” what you are about to hear is likely a lie. Someone paid for this lie and stands to profit somehow from this lie. If the story starts with “climate scientists warn”, it is a guaranteed lie.
