Biden has separately announced that he will ask the Environmental Protection Agency to examine what role climate change might have played in the storms. They do not connect with any cloud-base rotation and are not tornadoes, but because gustnadoes often have a spinning dust cloud at ground level, they are sometimes wrongly reported as tornadoes.
