\u201cCO2 is only present in the atmosphere in trace amounts (0.04%) and lacks sufficient enthalpy to have any measurable effect on the atmosphere\u2019s temperature.\u201d \u2013 Nelson and Nelson, 2024<\/strong><\/p>\n\n\n\n

New research (Nelson and Nelson, 2024<\/a><\/strong>) further documents the inconsequential role that CO2 plays in climate.<\/p>\n\n\n\n

Less than 4% of longwave infrared radiation is absorbed by greenhouse gases in the lower atmosphere. Greenhouse gases can have no effect outside of their narrow infrared atmospheric window.<\/p>\n\n\n\n

Of all the greenhouse gases, water vapor (30,000 ppm) has easily the most dominant effect, absorbing 84 times more radiation than CO2 does, and 407,000 times more radiation than CH4 (methane).<\/p>\n\n\n\n

If water vapor\u2019s absorption capacity were to change by a factor of 1 (i.e., from 84 times greater than CO2 to 83 times greater), this tiny change would \u201cwipe out all of what CO2 could have contributed\u201d within the greenhouse effect.<\/p>\n\n\n\n

Over the last 50 million years CO2 and temperature were negatively correlated (CO2 rose, temperatures fell or temperatures rose, CO2 fell) 42% of the time, and there was a glaring lack of recurring ratios, and \u201cmany ratios were zero or near zero.\u201d<\/p>\n\n\n\n

Over the last 1 million years \u201c87% of the ratios were negative or zero or near zero.\u201d This \u201cdirectly contradicts the Climate Change-CO2 hypothesis.\u201d<\/p>\n\n\n\n

Furthermore, high CO2 levels and\/or warming were not the cause of mass extinctions, as plants and animals \u201cthrive\u201d in much hotter temperatures than exist today.<\/p>\n\n\n\n

These conclusions are very similar to Davis (2017 and 2023), who determined that over the last 210 million years (a) CO2 falls as temperatures rise (negative correlation, r = -0.76), (b) mass extinctions occur 4.08 million years after CO2 peaks, and (c) global warming\/CO2 radiative forcing \u201cdid not cause extinction of biodiversity.\u201d<\/p>\n\n\n\n

Finally, approximately 89% of the warming over the period 1982-2018 could be attributed to the decline in cloud cover, which has allowed more solar radiation to be absorbed by the Earth\u2019s surface. The rest \u201cmay be attributed to other factors including the greenhouse effect applicable to water vapor.\u201d<\/p>\n\n\n\n

In other words, due to the decoupling of CO2 from global warming (or cooling), there is effectively no consequential role for CO2 in climate change.<\/p>\n\n\n\n
