"As we’ve shown, climate scientists have found overwhelming evidence that CO2raises global temperatures through radiative forcing.
"However, scientists long had trouble collecting one of the final pieces of evidence: high-quality, continuous satellite observations of outgoing IR radiation.
"But things changed in 2023 when a new study reported their findings after analyzing IR satellite measurements from 2003-2021.
" Raghuraman et al. (2023) explained that “these unprecedented observations provide measurements of Earth’s emitted thermal heat at fine-scale wavelengths, that is, the infrared spectrum, allowing us to pinpoint the effect of greenhouse gas concentration increases on Earth’s climate.
"We find large increases in the heat trapped by CO2, CH4, and N2O”[7].
"Outgoing radiation is a critical part of the energy balance model we discussed earlier (i.e., incoming vs. outgoing energy).
"The benefit of collecting these data via satellite is that they show the final ‘signature’ of outgoing radiation – the end result of the complex radiative transfers occurring on Earth.
"In summary, claims regarding CO2 saturation are nothing new, and proven to be inaccurate by several decades of scientific evidence.
"In recent times, new forms of scientific evidence, such as satellite observations of outgoing radiation[7], have only further shown that CO2 is not saturated and is still driving radiative forcing. "
