International alliance to combat ocean acidification announces government commitments at global climate action summit

SAN FRANCISCO, USA — As part of the Global Climate Action Summit, the International Alliance to Combat Ocean Acidification (OA Alliance) has announced new country, state and city members, including the Netherlands, Hawaii, Virginia, and Seattle who are committing to take action to protect oceans from the impacts of rising carbon emissions.

The OA Alliance, founded by the West Coast states of California, Washington, Oregon and the Canadian Province of British Columbia and Ocean Conservancy, welcomed these new members to a rapidly growing worldwide coalition of governments and supporting affiliate members from the scientific, industry, NGO, and academic sectors committed to creating regional ocean acidification action plans and sharing climate action best practices with each other.

Taking steps to fight climate change, ocean acidification in Virginia

Virginia will be taking a series of actions to help address the impacts of carbon pollution from fossil fuels.

Earlier this week, Governor Ralph Northam announced he has directed the Virginia Department of Environmental Quality to identify ways to improve environmental protections in the Commonwealth.

According to a release, leaders from several U.S. states and other countries gathered at the Global Climate Action Summit this week to work on climate solutions.

Virginia has committed to join the Transportation and Climate Initiative to reduce carbon pollution from the transportation sector, join the International Alliance to Combat Ocean Acidification and help with the Ocean Acidification Action Plan, and develop a framework for limiting methane leakage from natural gas infrastructure and landfills.

Ocean acidification and hypoxia council makes first recommendations to state legislature

Oregon is among the first places to document the impacts of “ocean acidification”— what happens when human-produced carbon dioxide is absorbed by seawater, resulting in chemical reactions that change the water’s pH and make it more acidic. Oregon is meeting this problem head on, most recently with the convening of the Oregon Coordinating Council on Ocean Acidification and Hypoxia.

Exhibition features East German photos, oceanic sculptures

Photographs from 1974 East Berlin and sculptures of sea slugs sit side by side at the fall exhibits at the Kehler Liddell Gallery in Westville.

The first exhibit, entitled Taking Sides, features work by New Haven photographer Sven Martson who recently published a book with photographs of daily life in East Berlin before the fall of the Berlin wall. Sculptor Gar Waterman created the second exhibit, entitled Canaries in a Blue Coal Mine. His work aims to draw attention to the impact of ocean acidification on sea creatures through his sculptures of animals such as cephalopods, sea slugs and fish. Both exhibits will be on display until October 7.

“Sven is covering what humans are doing to each other and my show is more about what we are doing to the environment,” Waterman said at the show’s opening on Sunday . “Both of our shows show how we are interacting we each other in one case and also how we are interacting with the world and the creatures that are in it.”

SBU professors join statewide effort to combat ocean acidification

Three Stony Brook faculty members have signed on to a statewide task force to combat ocean acidification, which was announced by New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos on Aug. 22.

Malcolm Bowman, a professor in the School of Marine and Atmospheric Sciences (SoMAS), R. Lawrence Swanson, the associate dean of SoMAS, and Dr. Carl Safina, an endowed research chair for nature and humanity at SoMAS, are all members of the team.

Ocean acidification and its impact on marine environments

Recently, news such as the story of a polar bear desperately reaching for an ice floe (Fig1A) and a global-scale coral bleaching (Fig1B) have become increasingly common. With climate change, extreme weather events are clearly increasing in frequency, such as intense heatwaves, powerful hurricanes, or severe droughts.

These effects do not only appear on the surface of the earth but also beneath the ocean, with harmful effects on various marine ecosystems. For example, ocean acidification (OA), which known as the evil twin of global warming, is one of the emerging threats to marine environments (Feely et al., 2004).

OA, which is caused when water absorbs 30% of atmospheric carbon dioxide (the earth absorbs about only 20 %), should be considered seriously. Experts have predicted a drop in seawater pH by 0.3-0.4 units by the end of the century and concluded that the average oceanic pH will decrease by 0.8 units by 2300.
