Megacryometeors: The phenomenon of abnormally large chunks of ice falling from a clear sky is giving rise to an interesting debate. Are they real? Are they from God? Are they a consequence of 'Global Warming'?

Wikipedia:
A megacryometeor is a very large chunk of ice, which, despite sharing many textural, hydro-chemical and isotopic features detected in large hailstones, are formed under unusual atmospheric conditions which clearly differ from those of the cumulonimbus clouds scenario (i.e. clear-sky conditions). They are sometimes called huge hailstones, but do not need to form in thunderstorms. Jesus Martinez-Frias, a planetary geologist of the Center for Astrobiology in Madrid pioneered research on megacryometeors in January 2000, after ice chunks weighing up to 6.6 pounds rained on Spain out of cloudless skies for 10 days.
