Have you ever seen a cartoon or advertisement that showed penguins and polar bears cavorting together in the snow?
On the flip side, have you ever seen a documentary film that showed penguins and polar bears together in the wild? Didn’t think so, since they live poles apart. Nevertheless, not everyone (advertisers included) understands the difference between Antarctica and the Arctic. Here are eight ways to tell them apart.
The National Marine Fisheries Service (NMFS) just took a huge step in preparing our ocean, fisheries and coastal communities for climate change. This type of foresight and required coordination is difficult, and hasn’t happened as often as it should in the past. The Western Regional Action Plan (WRAP) lays out why and how NFMS will develop, use, and apply science that helps West Coast fishery managers prepare for climate change.

Dr. KimberlyYates will be a panelist at an ocean acidification roundtable we are hosting in Miami this week. There, she will join other scientists, Florida elected officials and local businesspeople in discussing what ocean acidification has in store for Florida’s marine life and its coastal communities. Follow the meeting on Twitter via #FL_OA on Friday, June 17!
OC: Your research focuses on several marine habitats in Florida: coral reefs, estuaries and mangroves. How are they coping with ocean acidification?
Dr. Yates: Most of what we know about how ocean acidification is affecting these environments comes from experimental research. We know some marine organisms will be negatively impacted, and some may benefit. For example, some species that form their skeletons and shells from minerals made of calcium carbonate, like corals and some shellfish, are negatively impacted. Ocean acidification slows the rate at which they grow their skeletons and shells, and can also cause calcium carbonate minerals to dissolve.
Other species like seagrasses and some marine algae benefit from ocean acidification because it increases their growth rates. Coral reefs have been degrading rapidly over the past few decades, and recent research shows that some reefs in the Florida Keys are beginning to dissolve during certain times of the year from ocean acidification…which was not expected to happen for another few decades. Estuaries and mangrove wetlands support many species of shellfish, and ocean acidification may negatively impact those species and the economies that depend on shell fisheries. We are still learning about how changes caused by ocean acidification are impacting these habitats.
The news from the Arctic this week has been all about what’s leaving the Arctic. It’s good news when oil and gas companies leave the Arctic, but it’s really bad news when sea ice leaves the Arctic!!
First, let’s get to the good news. Repsol, an oil and gas company, just announced it’s abandoning 55 of its oil and gas leases in the Chukchi Sea and plans to abandon the remaining 38 over the next year. In addition, ConocoPhillips, Eni, Iona Energy and Shell have given up more than 350 leases covering more than 2 million acres in the Chukchi Sea. Soon, there will be only one lease remaining in the Chukchi Sea—and additional drilling on that lease is unlikely.
(And so should you. They keep our ocean and waterways healthy. And taste spectacular too.)
But we haven’t always done right by my favorite shelled creatures. It’s a fact reinforced by a slew of recent reports—plastic trash in the ocean could be hurting baby oysters, said the Washington Post and a new University of Miami study that found that the Atlantic Ocean has absorbed 100 percent more man-made carbon pollution in the past 10 years as it did the previous decade, spelling trouble for marine life and coastal communities.
The recent, and much heralded, Paris climate negotiations have led to a new global climate agreement. This historic deal involves 195 nations working toward a reduction in global greenhouse gas emissions and restricting future global warming to an increase of “substantially less than 2 degrees Celsius”, a substantially new target that was just one of many new components of the landmark climate agreement. Ocean Conservancy sat down with longtime friend and colleague Jay Manning, a climate and ocean expert from Washington state, to get his inside report from Paris and COP21, and what it means for the health of the world’s ocean.
Ocean Conservancy is bringing Danielle Dixson, an expert on coral reef fishes, to Capitol Hill to speak to congressional staffers about ocean acidification. She will be participating in a panel hosted by Ocean Conservancy in partnership with Senator Mazie Hirono (D-HI) and Representative Mark Takai (D-HI), along with the Ocean Caucus. She recently took some time to speak with us about her work at the University of Delaware.
