Why tornadoes are the hardest disasters to link to climate change

After tornadoes hit six U.S. states late last week, killing at least 88 people and razing warehouses, nursing homes and factories, many were quick to blame global warming for at least part damage. Over the weekend, numerous media speculated that global warming may have played a role and lobbied policymakers for answers. Deanne Criswell, the […]
