University of Washington: Seabirds face dire threats from climate change, human activity — especially in Northern Hemisphere


Share
Many seabirds in the Northern Hemisphere are struggling to breed and in the Southern Hemisphere, they may not be far behind. These are the conclusions of a study, published May 27 in Science, analyzing more than 50 years of breeding records for 67 seabird species worldwide.
The international team of scientists led by William Sydeman at the Farallon Institute in California discovered that reproductive success decreased in the past half century for fish-eating seabirds north of the equator. The Northern Hemisphere has suffered greater impacts from human-caused climate change and other human activities, like overfishing.
Seabirds include albatrosses, puffins, murres, penguins and other birds. Whether they soar or swim, all seabirds are adapted to feed in and live near ocean waters. Many scientists view seabirds as sentinels of habitat health because their lives and well-being depend on sound conditions both on land and at sea, said co-author P. Dee Boersma, a ....
