Ocean Salinities Reveal Strong Global Water Cycle Intensification During 1950 to 2000

摘要: Fundamental thermodynamics and climate models suggest that dry regions will become drier wet wetter in response to warming. Efforts detect this long-term sparse surface observations of rainfall evaporation remain ambiguous. We show ocean salinity patterns express an identifiable fingerprint intensifying water cycle. Our 50-year observed global changes, combined with changes from models, present robust evidence intensified cycle at a rate 8 ± 5% per degree This is double the projected by current-generation suggests substantial (16 24%) intensification occur future 2° 3° warmer world.
