Have the Oceans Had Enough? Largest Carbon Sink May Be Slowing Down

More than half of the CO2 emitted by human activities each year are taken up by natural carbon sinks, on land and in the ocean. However, recent studies suggest that anthropogenic emissions may be outpacing the ocean’s ability to take up CO2.
Le Quéré et al. (2009) constructed a global CO2 budget for 1959 – 2008 [...]

Altering the Abyss: Deep-Sea Ecosystems Affected By Climate Change

The abyssal plains, regions of the ocean below 2000 meters, cover 60% of the Earth’s surface. Scientists have long believed that the ecosystems located at these depths are relatively isolated and stable, immune to the dramatic changes rocking shallower ocean regions due to global warming. However, a recent paper* by Ken Smith, a marine ecologist [...]

Fishing For Answers: Connecting Ocean and Human Health

Walking home from an early appointment this morning, I considered what to write about for today’s blog post. An article about marine ecosystems and fisheries caught my eye yesterday. While intrigued, I was also reluctant – fisheries management is one subject that both interests and frustrates the hell out of me. I took one class [...]

India is Vulnerable and Acting to Address Climate Change

“India is vulnerable,” said Jairem Ramesh, India’s Minister for Environment and Forests at a breakfast meeting in Washington, DC last week. “We are responding to climate change because it is in our own self-interest.” While the U.S. Chamber of Commerce sheds members over its reactionary position on climate change, the US-India Business Council (USIBC), headquartered [...]

Global Warming Warps Marine Food Webs

Ocean acidification: the “other carbon problem” – now at a theater near you!

Since the beginning of the industrial revolution, the oceans have acted as a big sink, absorbing 30% of the CO2 that has been pumped into the atmosphere at a rate of 22 million tons a day. That would seem like good news; less atmospheric CO2 means less warming. But there’s a catch: the CO2 doesn’t [...]
