New studies show winter storms in the Southern Hemisphere are already reaching intensities predicted for 2080. Climate emergency is real!

A new study, published today in Nature Climate Change, will certainly make the IPCC—and other environmental bodies—take notice. A team of scientists led by Dr. Rei Chemke of Weizmann’s Earth and Planetary Sciences Department revealed a considerable intensification of winter storms in the Southern Hemisphere. The study, conducted in collaboration with Dr. Yi Ming of Princeton University and Dr. Janni Yuval of MIT, is sure to make waves in the climate conversation. Until now, climate models have projected a human-caused intensification of winter storms only toward the end of this century. In the new study, Chemke and his team compared climate model simulations with current storm observations. Their discovery was bleak: It became clear that storm intensification over recent decades has already reached levels projected to occur in the year 2080.
Chemke, Ming and Yuval’s study has two immediate, considerable implications. First, it shows that not only climate projections for the coming decades are graver than previous assessments, but it also suggests that human activity might have a greater impact on the Southern Hemisphere than previously estimated. This means that rapid and decisive intervention is required in order to halt the climate damage in this region. Second, a correction of the bias in climate models is in order, so that these can provide a more accurate climate projection in the future.Read the complete article….
