Biden calls on EPA to investigate role of climate crisis in deadly tornadoes

Experts say tornadoes with such intensity are rare later in the year during colder seasonal weather

Joe Biden has asked the US environmental protection agency (EPA) to investigate what role the climate crisis might have played in the deadly tornadoes that killed scores in Kentucky and several other states this weekend.

Experts have said that tornadoes with such intensity are rare later in the year during colder seasonal weather, and that Friday night's storms, which included one tornado tearing a path of more than 225 miles across Kentucky, appeared to be an anomaly.
