Warmer Climate Threatens Seas
Roger Di Silvestro
Global warming may be speeding up evaporation in tropical seas, sucking out water and making equatorial oceans saltier and polar seas less salty, according to research published recently in the journal Nature.
The changes could alter ocean currents, including the warm Gulf Stream, yielding colder European winters. Other results could include drought in some regions, increased precipitation in others and changes in the severity and frequency of floods and storms.
