Dead zones in our oceans have increased dramatically since 1950

This year the Catatumbo Lightning was approved for inclusion in the 2015 edition of Guinness World Records, dethroning the Congolese town of Kifuka as the place with the world's most lightning bolts per square kilometer each year at 250. Scientists think the Catatumbo, named for a river that runs into the lake, is normal lightning that just happens to occur far more than anywhere else, due to local topography and wind patterns.
