Global Warming temperatures could multiply Katrina-like Extreme hurricanes

Global Warming temperatures could multiply Katrina-like Extreme hurricanes

Scientists have long studied the relationship between warmer sea surface temperatures and cyclonic, slowly spinning storms in the Atlantic Ocean, but the new study attempts to project how many of the most damaging hurricanes could result from warming air temperatures as well. The extreme storms are highly sensitive to temperature changes, and the number of […]
