Make Oceans Vast Carbon Sinks

House and colleagues from Harvard and Pennsylvania State University said they found a way to remove hydrochloric acid from the ocean and neutralize it using silicate from volcanic rocks. That increases the ocean's alkalinity, so it can store more atmospheric CO2 as bicarbonate, already the most common form of carbon in the oceans. "That means we may be able to safely and permanently remove excess CO2 in a matter of decades rather than millennia," House said, describing the process as accelerating the natural system to industrial rates. ... http://www.cbc.ca/technology/story/2007/11/08/oceans-carbon.html
