Variations of atmospheric 12CO2 and 13CO2 from the year 1000 to 2024
W. A. van Wijngaarden, W. Happer
A simple model gives good agreement between observed emissions of CO2 into the atmosphere from the combustion of fossil fuels and observed increases of the atmospheric concentratio…
Acidification of Water by CO2
W. A. van Wijngaarden, P. Ridd, M. Cornell +1
Fundamental inorganic chemistry shows that increasing concentrations of atmospheric CO2 will have no harmful effect on organisms that live in the natural waters of the Earths, and…
Livestock, Methane and Climate
D. Alexander, J. D. Ferguson, A. Glatzle +2
Methane emissions by livestock have a negligible effect on Earth's temperature. For example, killing all of the approximately 1.6 billion cattle on Earth in the year 2025, when thi…
Sunlight, the Bond Albedo, CO2, and Earth's Temperature
R. Louw, W. A. van Wijngaarden, W. Happer
The main determinants of Earth's absolute surface Temperature, T, are the solar constant, S, the Bond albedo, A, and the effective emissivity for thermal radiation, e. In this note…
Net Zero Averted Temperature Increase
R. Lindzen, W. Happer, W. A. van Wijngaarden
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 n…
Effect of Greenhouse Gases on Thermal Emissivity by Clouds
W. A. van Wijngaarden, W. Happer
Greenhouse gases, most importantly water vapor, increase the emissivity and decrease the albedo of clouds for thermal radiation. The modifications, which can be of order 10% for op…
