IOW, to get to the guts of this issue, at the resolution of
radiative transfer and
absorption profiles,
including times series and under different humidities, is probably impossible via the web.
They assume a basis for all this, the
radiative heat
absorption by CO2 (this is in their founding documents), and produce massive summaries, generally
including long term ordinary linear regression in approriately applied to a time series, and then make a statement such as «an increase of.2 deg C / decade».
1950s: Research on military applications of radar and infrared radiation promotes advances in
radiative transfer theory and measurements = > Radiation math — Studies conducted largely for military applications give accurate values of infrared
absorption by gases = > CO2 greenhouse — Nuclear physicists and chemists develop Carbon - 14 analysis, useful for dating ancient climate changes = > Carbon dates, for detecting carbon from fossil fuels in the atmosphere, and for measuring the rate of ocean turnover = > CO2 greenhouse — Development of digital computers affects many fields
including the calculation of radiation transfer in the atmosphere = > Radiation math, and makes it possible to model weather processes = > Models (GCMs)-- Geological studies of polar wandering help provoke Ewing - Donn model of ice ages = > Simple models — Improvements in infrared instrumentation (mainly for industrial processes) allow very precise measurements of atmospheric CO2 = > CO2 greenhouse.
