Climate

CO2's properties as a greenhouse gas, absorbing and re-emitting infrared radiation, were established experimentally by physicist John Tyndall in 1859 and have been confirmed by countless laboratory measurements and satellite observations since. This is foundational physics with no credible scientific dispute.

The IPCC Sixth Assessment Report (2021-2023) concludes it is unequivocal that human influence has warmed the atmosphere, ocean, and land. More than 97% of actively publishing climate scientists and over 99% of peer-reviewed climate papers endorse anthropogenic climate change.
