Heavy rainfall events becoming more frequent on Big Island, Hawaii      (via sciencedaily.com) 

A recent study determined that heavy rainfall events have become more frequent over the last 50 years on Hawai'i Island. For instance, a rare storm with daily precipitation of nearly 12 inches, occurring once every 20 years by 1960, has become a rather common storm event on the Big Island of Hawai'i -- returning every 3-5 years by 2009.

NASA study shows 13-year record of drying Amazon caused vegetation declines      (via sciencedaily.com)     Original source 

A 13-year decline in vegetation in the eastern and southeastern Amazon has been linked to a decade-long rainfall decline in the region. With global climate models projecting further drying over the Amazon in the future, the potential loss of vegetation and the associated loss of carbon storage may speed up global climate change.
