PHYSICS DEMONSTRATES THAT INCREASING GREENHOUSE GASES CANNOT CAUSE DANGEROUS WARMING, EXTREME WEATHER OR ANY HARM
More Carbon Dioxide Will Create More Food.
Driving Greenhouse Gas Emissions to Net Zero and
Eliminating Fossil Fuels Will Be Disastrous for People Worldwide.
June 7, 2025
SUMMARY
At the outset it is important to understand that carbon dioxide has two relevant properties, as a creator of food and oxygen, and as a greenhouse gas (GHG).
As to food and oxygen, carbon dioxide is essential to nearly all life on earth by creating food and oxygen by photosynthesis. Further, it creates more food as its level in the atmosphere increases. For example, doubling carbon dioxide from today’s approximately 420 ppm to 840 ppm would increase the amount of food available to people worldwide by roughly 40%, and doing so would have a negligible effect on temperature.
As to carbon dioxide as a GHG, the United States and countries worldwide are vigorously pursuing rules and subsidies under the Net Zero Theory that carbon dioxide and other GHG emissions must be reduced to Net Zero and the use of fossil fuels must be eliminated by 2050 to avoid catastrophic global warming and more extreme weather. A key premise stated by the Intergovernmental Panel on Climate Change (IPCC) is the “evidence is clear that carbon dioxide (CO2) is the main driver of climate change,” where “main driver means responsible for more than 50% of the change.”[1]
The Biden Administration adopted over 100 rules and Congress has provided enormous subsidies promoting alternatives to fossil fuels premised on the Net Zero Theory. The EPA Endangerment Finding, for example, asserts “elevated concentrations of greenhouse gases in the atmosphere may reasonably be anticipated to endanger the public health and to endanger the public welfare of current and future generations.”[2]
