Seabed may be too turbulent to store carbon

The ocean floor has been eyed as a potential site to sequester carbon, the idea being that we can get CO2 far, far away from human activity by banishing it to the earthly equivalent of the Final Frontier. But if you get CO2 out of the way of humans, it may instead be smack dab in the middle of natural forces. In an editorial published this week in the journal Nature Geoscience, the fallibility of burying carbon below the sea bed is explored. The chief point of concern is that the ocean bed is actually... [Read more]

Tens of thousands of years needed for Earth to recover from mass carbon releases

It’s easy to come up with ways that carbon is released into the atmosphere — an erupting volcano, a massive wildfire, or in today’s world, millions of fossil fuel burning cars and power plants. But how does carbon eventually get put back into the earth? A paper published in Nature Geoscience this month by scientists at Purdue University and the University of California at Santa Cruz examined the Palaeocene-Eocene Thermal Maximum, a 170,000 year period of global warming that took... [Read more]
