Is weather becoming more extreme?

Extreme weather events have always been with us, and always will be. One can't point to a single severe storm, or even an entire harsh winter, as evidence of climate change. But a trend of weather intensity, and oddity, grows. Droughts linger longer. Hurricanes hit harder. Snowstorms strike long after winter should have ended. World record hailstones fall. China endures a crippling drought, and then punishing floods. Millions are displaced in a flood of historic proportion in Pakistan. The U.S. sees the Mississippi River reach historic flood crests, and then sees the largest wildfire in Arizona history. None of these events on their own mean anything. Collectively, do they mean we're seeing the earth's climate change before our eyes? -- Lane Turner (47 photos total)
