Cost-benefit analysis confirms that it would be better to abandon net-zero policy initiatives and “do nothing” on greenhouse gas emissions. [emphasis, links added]
New research finds that the maximum possible impact of carbon dioxide on climate is “negligible.”
The cumulative expected temperature change for a doubling of carbon dioxide concentrations from 400 PPM to 800 PPM is at most only 0.81°C, which “certainly would not trigger alarm or declare a climate emergency.”
As shown in Figure 1 in the paper [pictured below], Adding carbon dioxide has the strongest effect on temperature when carbon dioxide concentrations are below 100 PPM.
after that, Even as the concentration rises to 900 PPM, the CO2 impact decreases logarithmically to less than 0.05°C.
Through heat transfer calculations, it is expected that even if governments around the world truly achieve all of their proposed net zero policy goals, It would only lead to a 0.28°C drop in global temperatures.
in other words, It will have no “measurable impact” on climate.
The tens of trillions of dollars spent to achieve insignificant reductions in global temperatures would be better spent on policies that promote global warming. Improve the economic, health and educational conditions of the poor.
