"We can't say with absolute certainty that it was because of climate change... there is a lot of things that we don't know for certain, I don't want to say anything that's not precisely true," Biden said when asked if the tornado was caused by climate change. "What is certain is it is one of the worst tornado disasters that we've had in the country."
Moreover, Biden said that another thing that is for certain is how the tornado formed, how many places it touched down and the length of its path.
Biden will visit Kentucky on Wednesday after at least four devastating tornadoes ripped through the state, leaving at least 64 dead and dozens more unaccounted for.
Two tornado-related deaths have also been reported in the state of Arkansas, four in Tennessee and two in Missouri. In Illinois, six people died in a partial collapse of an Amazon warehouse in the city of Edwardsville.
