UPDATE: Large storms like blizzards more severe but less frequent now as Earth's climate changes

The Canadian-led study noted that warmer air can hold more moisture, meaning more fuel for rain, hail or snow, and found knock-on effects on how the atmosphere generates storms "In a future climate, the global atmospheric circulation might comprise highly energetic storms," they wrote in the journal Science. At the same time, "fewer numbers of such events" may occur, they said. More evaporation and precipitation of water are likely to use up more energy in the atmosphere, contributing to reduce the intensity of winds around the world. The report looks at how the atmosphere works as a heat engine, shifting heat from the sun from the tropics towards the poles. It is part of the effort to pin down the probable affects of climate change to help everyone from farmers to city planners cope with the shifts.
