In the Central U.S., officials in seven states issued tornado warnings on Wednesday, making it the 14th straight day of severe weather that’s shattered previous records for the month of May. In just the last week alone, tornadoes have been linked to at least seven deaths and scores of injuries. Over the past 30 days, meteorologists have logged more than 500 tornadoes across the U.S.—a record total that’s consistent with models predicting more extreme weather due to climate change.
