Read here. It's another case of wild speculations by climate alarmist scientists that starts it; then it is hysterically blown out of proportion by the mainstream megaphone; and, it is then proven to be demonstrably wrong (the wild speculation) by real scientific research. Surprise!
Everyone repeat after us: any climate or environmental predicted calamity, catastrophe, or crisis reported by the mainstream media is bogus - ignore it. Again. The world is not going to end because of human CO2. In fact, the world may become better because of more CO2.
