Extreme weather events are accelerating tidal wetland loss, satellite data show

Phys · · 682 words · By University

Researchers from the University of Connecticut and the University of Victoria used 40 years of satellite data to analyze tidal wetland loss in the U.S. The study, published in Nature Communications, finds that while sea level rise remains the primary driver of loss, extreme weather events are increasingly accelerating the rate of decline.
