"Storms of the Harvey variety will become not one-in-1,000-year events but one-in-100."

Sorry to see Ms. Parker make such an absurd claim. There is nothing "simple" about weather, and there is certainly nothing simple about climate.  We know the climate is changing, and we know that human activity plays a role. But we don't know much more than that. Nor do we know whether the changes we encounter will ultimately be harmful or beneficial or something in between.
