SUMMIT COUNTY — Even as global warming deniers toot their horns at the discredited Heartland Institute‘s annual anti-science conference, a team of researchers say they’ve detected a pattern of changes in ocean salinity that marks a clear “fingerprint of climate change.”

Analyzing observed ocean salinity changes and the relationship between salinity, rainfall and evaporation in climate models, they determined the water cycle has strengthened by four per cent from 1950-2000. This is twice the response projected by current generation global climate models, according to lead author, Dr. Paul Durack, a post-doctoral fellow at the Lawrence Livermore National Laboratory.
