Every time there is some sort of weather disaster somewhere, someone blames it on human-caused global warming. Maybe not directly, but the implication is clear. “While we can’t link individual events to global warming, the increase of this type of event is consistent with our expectations, blah, blah…”
Most recently this came in testimony from White House Science Adviser John Holdren before the Committee on Science, Space, and Technology of the U.S. House of Representatives:
In general, one cannot say with confidence that an individual extreme weather event (or weather-related event)—for example, a heat wave, drought, flood, powerful storm, or large wildfire—was caused by global climate change. Such events usually result from the convergence of multiple factors, and these kinds of events occurred with some frequency before the onset of the discernible, largely human-caused changes in global climate in the late 20th and early 21st centuries. But there is much evidence demonstrating that extreme weather events of many kinds are beginning to be influenced—in magnitude or frequency—by changes in climate.
Holdren then goes to list a bunch of types of extreme weather whose characteristics have changed (remarkably, all becoming worse), adding that:
There are good scientific explanations, moreover, supported by measurements, of the mechanisms by which the overall changes in climate resulting from the human-caused build-up of heat-trapping substances are leading to the observed changes in weather-related extremes.
