Is the human-induced increase in the atmosphere’s carbon dioxide concentration good or bad for the earth and its inhabitants? A number of scientists who base their opinions primarily on the predictions of climate models vociferously claim that it’s bad. Other scientists, who base their opinions primarily on real-world weather measurements and historical proxy temperature reconstructions, along with the known positive effects of atmospheric CO2 enrichment on terrestrial plant growth and development, as well as its benign effects on aquatic plants and animals, are equally adamant that it’s good.
