The Earth’s atmosphere has warmed about one degree Celsius since 1850, and CO2 has increased approximately 130 parts-per-million since the beginning of the Industrial Revolution to about 415 ppm today This combination of modest warming and a rise in atmospheric CO2 has provided a huge benefit to the Earth’s ecosystems and to humanity.

It is accepted by experts on both sides of the issue that carbon dioxide retains small amounts of solar radiation — heat — that otherwise would escape into outer space. Proponents of catastrophic man-made warming exaggerate this phenomenon, using unlikely and unsupportable high-end projections of the warming effect to achieve extreme heat scenarios of the future.
