ScienceDaily (Sep. 11, 2009) — The world faces a compounding series of crises driven by human activity, which existing governments and institutions are increasingly powerless to cope with, a group of eminent environmental scientists and economists has warned. Writing in the journal Science, the researchers say that nations alone are unable to resolve the […]
The graphs show Iceland Sea winter surface water changes in pH, and the saturation state of aragonite. The anthropogenic increase of atmospheric carbon dioxide affects the Nordic Seas both at the surface and at depth. In the surface, the pH has decreased from 8.13 to 8.08 between 1985 and 2008, and the aragonite saturation, which […]
The same things that make Alaska’s marine waters among the most productive in the world may also make them the most vulnerable to ocean acidification. According to new findings by a University of Alaska Fairbanks scientist, Alaska’s oceans are becoming increasingly acidic, which could damage Alaska’s king crab and salmon fisheries. This spring, chemical oceanographer […]
By Art Chimes, Washington, D.C. Rising levels of carbon dioxide in the atmosphere are a major contributor to climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry, potentially threatening marine life. Montana State University scientist Robert Dore has been taking samples of water in the Pacific […]
By Noreen Parks In addition to weakening Earth’s natural shield against excessive radiation levels, ozone depletion above Antarctica has significantly dampened the Southern Ocean’s ability to absorb atmospheric CO2 and has accelerated acidification of southern polar waters, according to new research reported online June 20 in Geophysical Research Letters (2009, DOI 10.1029/2009GL038227). Of the atmospheric […]
Oyster larvae have been dying by the billions. Scientists suspect it’s a sign that carbon dioxide is dramatically affecting the ocean. By Craig Welch, Seattle Times environment reporter WILLAPA BAY, Pacific County — The collapse began rather unspectacularly. In 2005, when most of the millions of Pacific oysters in this tree-lined estuary failed to reproduce, […]
Low-oxygen “dead zones” in the ocean could expand significantly over the next century, according to marine chemists. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. Concentrations of carbon dioxide are increasing rapidly in the […]
By Dan Berrett An East Stroudsburg University professor has studied a delicate sea creature off Japan’s coast, and shed new light on how climate change is disrupting the ocean’s food chain. "This is the first clear link between an animal we know is threatened by ocean acidification and a variety of deep-sea species," said Jay […]
By Andrew Darby, Hobart THE first evidence suggests that a predicted rise of atmospheric carbon dioxide will wreak havoc on krill, the tiny crustacean at the heart of the Antarctic food web. Although public sympathy for the crustacean is undetectable, polar life such as penguins, seals and whales would wither without it. Captive-bred krill at […]
