Reefs at risk: Roundup at the not-so-OK coral corral

bleached coral

Coral, the reef-building organisms responsible for some of the oceans’ most vital ecosystems, are in trouble around the world because of climate change, ocean acidification and human interference. But lots of people are also trying to save coral reefs before it’s too late. Here’s a roundup of some of the latest research into this important [...]

In Indonesia, a Worrying Silence on Climate Change

Resilient coral. A colony of table coral that broke down, recovered and is now growing into other direction.

Dive into the limpid waters off Indonesia’s resort island of Bali and you’ll spot the beginnings of an environmental success story. Older reefs are recovering from the devastating coral bleaching of 1998 and 2009. New corals are now taking hold. On shore, local fishermen also see improvement. There are, at long last, more and bigger [...]

To catch a fallen sea angel: A mighty mollusk detects ocean acidification

  "What’s more," snapped the Lorax. (His dander was up.) "Let me say a few words about Gluppity-Glupp. Your machine chugs on, day and night without stop making Gluppity-Glupp. Also Schloppity-Schlopp. And what do you do with this leftover goo?… I’ll show you. You dirty old Once-ler man, you! "You’re glumping the pond where the [...]

Acid Maps Reveal Worst of Climate Change

global-ocean-ph-map-february-2005

Much of the change in climate change is happening to the ocean. It’s not just the extra heat hiding within the waves. The seven seas also absorb a big share of the carbon dioxide released by burning the fossilized sunshine known as coal, natural gas and oil. All those billions and billions of CO2 molecules [...]

Credit: Wikimedia Commons Overfishing and pollution have pushed life in the high seas to the brink of collapse, according to a new report from the Global Ocean Commission. “The oceans are a failed state,” David Miliband, co-chair of the commission, told Reuters. The commission has implored governments to set a five-year deadline to deal with [...]

Climate change is real, it’s here and it will be affecting the planet for a long, long time. That’s the lesson of the latest iteration of the Intergovernmental Panel on Climate Change‘s state of climate science report, released in its entirety on January 30. Concentrations of carbon dioxide in the atmosphere have now touched 400 [...]

How to Save Coral Reefs from Climate Change: Genetic Manipulation

palmyra-reef

What’s the best idea for reducing the impacts of ocean acidification on the environment and society? After all, carbon dioxide levels in the atmosphere continue to go up and up and up, which suggests that the pH of seawater will continue to fall and fall and fall. The Paul G. Allen Family Foundation has weighed [...]

Talk about management by committee: one group of more than 800 scientist authors to cope with more than 9,000 scientific publications on climate change and more than 20,000 comments from “expert reviewers” (plus another 30,000 or so from various other interested parties.) Now the Intergovernmental Panel on Climate Change is into four days of wrangling [...]

Ocean acidification may disrupt the marine nitrogen cycle

Ocean acidification, the result of roughly a third of global CO2 emissions dissolving into the seawater and lowering its pH, has complicated and poorly understood consequences for ocean ecosystems. Scientists already know that a drop in ocean pH affects the carbon cycle, reducing the carbonate ions that organisms like corals, mollusks and crustaceans use to [...]

Could ocean acidification deafen dolphins?

As more and more carbon dioxide enters the Earth’s atmosphere, oceans are becoming more acidic. In fact, this acidification has been blamed for everything from killing off coral to aiding algae and even super-sizing fish ear bones. But the changing marine chemistry may also be altering the deep sea’s acoustic environment, according to a new [...]

8 Awesome Octopus Facts for World Oceans Day

octopus facts world oceans day

Octopuses are amazing. In honor of World Oceans Day, here are eight facts about these incredible creatures. 8. Octopuses are masters of camouflage. However, research suggests that octopuses don’t try to blend into their entire environment—to look like coral, sand and seaweed all at once. A study published last year  found that octopuses, instead, picked [...]
