Das andere CO2-Problem (video; in German)

Wissenschaftler beenden achtjähriges Projekt zur Ozeanversauerung: Zuviel Kohlendioxid lässt weltweit die Ozeane versauern. Meeres-Forscher des Netzwerkes BIOACID warnen vor den dramatischen Auswirkungen.

Rising CO2 & sea life (audio)

A new analysis finds that most if not all marine species will be affected by the rising acidity in the oceans from CO2 emissions. Research scientist Ulf Riebesell of the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany spoke with host Steve Curwood about his team’s findings and what increasing ocean acidity could mean for species like corals and cod as well people who depend on the sea for food.

Oceans are about to become giant pools of seltzer

Climate change’s spike up in carbon dioxide means that oceans—which cover 71 percent of Earth’s surface—are going to become cesspools.

“I have to admit, we’re just scratching the surface here,” Ulf Riebesell told The Daily Beast recently. He’s talking about how only now, decades after climate change was recognized as an impending crisis, we’re figuring out how the extreme temperatures facing Earth will affect the water covering 71 percent of the planet.

Riebesell is the lead author of a landmark study involving more than 250 scientists, 580 peer-reviewed articles, 20 German research institutions, and 350 marine species, trying to understand how climate change will affect the world’s oceans. Eight diligent years and $25.5 million later, Riebesell’s team’s research was presented at the annual United Nations Climate Change Conference in Bonn, Germany, this week.

Ocean acidification threatens New England fishing industry

Among the many environmental byproducts of global climate change, the lesser known process called ocean acidification is posing an immediate threat the New England shellfish industry, experts say.

As excess carbon dioxide is absorbed into the oceans combined with freshwater runoff into coast waters, it is starting to have profound effects on marine life, from oysters to tiny snails at the base of the food chain.

In New Hampshire, Sen. David Watters (D-Dover), oversaw the passage of a bipartisan 2016 bill that established The New Hampshire Coastal Marine Natural Resources and Environment Commission which began meeting earlier this year.

Ocean acidification threatens Bering Sea crabs. But can they adapt? (audio)

Ocean acidification could threaten some of Alaska’s most important fisheries. Researchers warn that populations of red king crab in the Bering Sea – made famous by the show The Deadliest Catch – could collapse by the end of the century.

But it’s possible the crabs might be able to evolve and adapt to the changing oceans. The big question is – will they have enough time?

What do jellyfish teach us about climate change?

A new study shows that the biological effects of two ecosystem changes can be greater than their individual impacts

What do jellyfish teach us about climate change?

A lot. At least that’s what I learned after reading a very recent paper out in the journal Global Climate Change. The article, “Ocean acidification alters zooplankton communities and increases top-down pressure of a cubazoan predator,” was authored by an international team of scientists – the paper looks at impacts of climate change on life in the world’s oceans.

Burke-o-Lator helps researchers monitor Sitka’s waters (audio)

For people who depend on the oceans for their livelihood, climate change is about a lot more than weather. Some of the carbon in the atmosphere — which is gradually warming the planet — is absorbed by the oceans, making their basic chemistry more acidic, and making it difficult for organisms like mussels to build their shells. Until recently, it was difficult to measure the amount of carbon in seawater. But now, thanks to garage-laboratory ingenuity and some repurposed beer bottles, researchers at the Sitka Tribe of Alaska can keep tabs on ocean acidification around the clock. KCAW’s Katherine Rose has more.
