Benny Peiser of Liverpool U. has an interesting academic mail list dealing a lot with climate change. Today he offered the following two quotes:
"Since the late 1960s, much of the North Atlantic Ocean has become less salty, in part due to increases in fresh water runoff induced by global warming, scientists say."
--Michael Schirber, LiveScience, 29 June 2005
"The surface waters of the North Atlantic are getting saltier, suggests a new study of records spanning over 50 years. They found that during this time, the layer of water that makes up the top 400 metres has gradually become saltier. The seawater is probably becoming saltier due to global warming, Boyer says."
--Catherine Brahic, New Scientist, 23 August 2007
More salty, less salty? Must be global warming. I'm awaiting the report: "Atlantic just as salty as always: global warming to blame."
