Extreme weather events in the first half of 2013 included another summer heat wave with bush fires throughout Australia (in January), recent temperatures of 40 C + with forest fires in the American West, and numerous forest fires in Russia, eastern Canada, and Indonesia. In Alaska snow in May was followed by temperatures of 30 C + in June. Meanwhile, floods swept several regions in Central Europe, western Canada, the Philippines, Thailand -- and also Nepal and northern India, where several hundred people died in mudslides. And it is going to get worse. Much worse.
