Precision research by physicists William Happer and Willem van Wijngaarden has determined that the current levels of atmospheric carbon dioxide and water vapor are "saturated." In radiation physics that means adding more CO2 or water molecules will bring modest warming that will benefit plant growth, and thus all life on Earth. More CO2 and H2O will not cause dangerous warming.
From this point forward, emissions from burning fossil fuels will bring little additional global warming, and what does occur will improve forests, grasslands and agriculture. There is no climate emergency.
