Scientists see rise in tornado-creating conditions

When at least 80 tornadoes rampaged across the United States, from the Midwest to the Gulf of Mexico, last Friday, it was more than is typically observed during the entire month of March, tracking firm AccuWeather.com reported on Monday.

According to some climate scientists, such earlier-than-normal outbreaks of tornadoes, which typically peak in the spring, will become the norm as the planet warms.
