Scientists warn that a crucial ocean current could collapse, altering global weather – the Los Angeles Times

The Atlantic Meridional Overturning Circulation acts as a conveyor belt of ocean water from Florida to Greenland. Along the journey north, water near the surface absorbs greenhouse gases, which sink down as the water cools near Greenland. In this way, the ocean effectively buries the gases deep below the surface (Courtesy of NASA's Goddard Space Flight Center, caption by Ellen T. Gray)

Scientists warn that a crucial ocean current could collapse, altering global weather…The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that circulate water in the Atlantic Ocean like a conveyor belt, helping to redistribute heat and regulate global and regional climates. New research, however, warns that the AMOC is weakening under a warming climate, and could potentially suffer a dangerous and abrupt collapse with worldwide consequences…

Category 6-level hurricanes are already here, a new study says – Grist Magazine

In the real world, Category 5 is synonymous with the biggest and baddest storms. But some U.S. scientists are making the case that it no longer captures the intensity of recent hurricanes. A paper published Monday in the Proceedings of the National Academy of Sciences lays out a framework for extending the current hurricane-rating system…with a new category for storms that have winds topping 192 miles per hour. According to the study, the world has already seen storms that would qualify as Category 6s…
