Patterns of 50-year surface salinity changes (PSS-78 50 / year). (A) The 1950–2000 observational result from P. J. Durack, S. E. Wijffels, “Fifty-year trends in global ocean salinities and their relationship to broad-scale warming”, J. Clim. 23, 4342 (2010). ABSTRACT: Fundamental thermodynamics and climate models suggest that dry regions will become drier and wet regions […]
[Declaring an end to the Big Dry seems premature, cf.: While the systematic accumulation of rainfall deficits was reversed with the heavy spring and summer rainfall of 2010, the total two-year record rainfall makes up for about one third of the total rainfall ‘missed out on’ since 1996.

By David Fogarty; Editing by Ed Davies26 April 2012 SINGAPORE (Reuters) – Scientists have detected a clear change in salinity of the world’s oceans and have found that the cycle that drives rainfall and evaporation has intensified more than thought because of global warming. The finding published on Friday helps refine estimates of how different […]
