El Niño variant could drive hurricanes in Atlantic

(NYTimes): Scientists have known for some time that El Niño, the warm spell that turns up every four or five years in the waters of the eastern Pacific Ocean, reduces hurricane activity in the Atlantic. But in a new study, researchers at the Georgia Institute of Technology have linked a variant of that pattern — periodic warming in the central Pacific — to more frequent hurricanes in the Atlantic, particularly on the Gulf Coast and in the Caribbean. Researchers however said they were unable to confirm if this was linked to climate change.
