Before discussing
tornadoes, it is important to note that it is scientifically uncontroversial to conclude that climate change is causing
more violent weather particularly in the form of: (a)
more damaging thunder storms, (b) the kind of devastating flooding we have seen this year in Australia, Pakistan, Brazil, Columbia, Venezuela, along the Mississippi and the Tennessee valleys, and (c)
more severe droughts such as those experienced this year in China, Brazil, and Texas.
