Millions of people in southern Africa depend on monsoon rains that begin around November and last until March or April. If the monsoon is erratic, millions of people can suffer. So far in 2014-2015, the monsoon in southeastern Africa has been anything but normal.
A major winter storm was still blustering its way through the U.S. Northeast this morning, with continued snow accumulations and high winds predicted for many areas. How will this event compare to the region’s most historic storms?
In the Northeast, the amount of rain that came down in very heavy events increased by more than 70 percent between 1958 and 2010. A new law in New York requires state agencies to start thinking ahead about increases in extreme rain and other climate change risks.
Models project that extreme dust events combined with global warming could advance the spring thaw in the mountains of the Upper Colorado River Basin by as many as 6 weeks by 2050. The earlier disappearance of snow could amplify water disputes, extend the fire season, and stress aquatic ecosystems.
Maps of the thousands of storms that have passed through the Eastern Hemisphere tropical oceans in the past century or so reveal a more crowded landscape than similar maps of the Western Hemisphere. Unlike the Western Hemisphere, where storms are mostly confined to areas north of the equator, the Eastern Hemisphere sees storms in both north and south tropical waters.
