My reply:
It's getting so boring to see the same ignorance repeated over and over again.
Once and for all, CO2 isn't a greenhouse gas because radiation from Earth's surface can't heat a gas. Any photons absorbed are soon reemitted in another direction, leaving the molecule's temperature unchanged. If a CO2 molecule has no heat, it can't heat anything else. Individual photons aren't heat, they just packets of pure energy. Heat only exists in molecules.
The greenhouse effect is based on a pack of lies confusing radiation with conduction and convection.
Get it straight right now and become a real expert that doesn't babble about CO2 saturation and Antarctic ice cores.
