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 [...]

Global Warming Bubbles up from the Deep

European scientists have discovered more than 250 plumes of methane (CH4) gas bubbles rising from the seabed of the West Spitsbergen continental margin in the Arctic, at a depth of 150 to 400 meters. The warming of Arctic currents by 1° over the last 30 years has triggered the release of methane, a potent [...]

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 [...]
