Worst-case predictions for global warming confirmed in new study
The worst-case projections for global warming appear likely to be correct, according to research by the Carnegie Institution in California. The study compared climate models to real-world observations of how the atmosphere is behaving and concluded that the simulations that were closest to such observations were the ones which predicted the greatest warming. According to the United Nations’ highest prediction for greenhouse-gas concentrates, this could see temperatures rise by almost 5 °C by 2100, 15% hotter than earlier predictions. The research also found that the odds of temperatures rising by over 4 degrees by 2100 rose from 62% to 93%.
