Climate experts have long warned that global warming could bring an increase in extreme weather, such as hurricanes and drought. They never mentioned 20-pound chunks of ice falling from the clear blue sky, tearing through roofs, shattering windshields, and gouging impact craters. Yet reports of such "clear-sky ice fall events" have been on the rise worldwide in recent years, and in February Spanish researchers offered further evidence that the increase could be due to climate change. Monster ice meteors, called megacryometeors, drop singly from cloudless skies and can weigh a couple hundred pounds. More than 50 such events have been reported globally in the past seven years alone, according to Jesus Martinez-Frias, a planetary geologist at the Center for Astrobiology in Madrid.
