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 [...]

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 [...]

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 [...]

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 [...]
