Climate change lawsuits ask whether fossil fuel companies are responsible

Just 20 energy companies account for one-third of greenhouse emissions since 1965, according to a new study.

The Climate Accountability Institute’s Richard Heede tallied up all the fossil fuels extracted by every company through 2017 and calculated the emissions. The data is public, the math is straightforward and the emissions are indisputable.

The top 10 companies, in order, are, predictably, Saudi Aramco, Chevron, Gazprom, Exxon Mobil, National Iranian Oil Co., BP, Royal Dutch Shell, Coal India and PEMEX. More details are available online at

    Burning fossil fuels is irrelevant to climate change.

    Hitran, using Quantum Mechanics, calculates the relative absorb/emit intensity of water vapor molecules vs CO2 molecules. Comparison at zero altitude is shown here. Comparison by the ratio of the summation of intensities (line lengths) for each wavenumber for each molecule species is 8.7/0.07 = 124. On average at ground level, WV molecules outnumber CO2 molecules by about 10,000/410 ≈ 24 to one. After accounting for molecule count, each WV molecule is still more than 124/24 ≈ 5 times more effective at absorb/emit of thermal radiation than a CO2 molecule.

    The relative effectiveness of the increases of WV and CO2 over 30 years is calculated as follows:
    CO2 increase in 3 decades, 1988 to 2018 = 407 – 348 = 59 parts per million by volume (ppmv)

    Water vapor increase trend from NASA/RSS TPW data, is 0.04272/28.9 * 100 * 10 = 1.47 % per decade.

    Average global WV = 10,000 ppmv. WV increase in 3 decades = .0147 * 10,000 * 3 = 441 ppmv

    Therefore, WV has been 441/59 * 5 = 37+ times more effective at increasing ground level temperature than CO2. (Most of the world has been falsely indoctrinated.)

    Above the tropopause (about 33,000 feet) WV molecules are reduced to about 32 ppmv because of the low temperature while CO2 molecules remain at 410 ppmv. Therefore, CO2 molecules outnumber WV molecules 410/32 ≈12 to one. At higher altitudes the molecule spacing increases and more and more of outward directed radiation makes it all the way to space. The increased cooling by more CO2 well above the tropopause counters and apparently fully compensates for the tiny added warming from CO2 increase at ground level. The result is that burning fossil fuels does not significantly affect climate.
