Dumping iron at sea can bury carbon for centuries, study shows | Environment | guardian.co.uk
Smetacek's team added seven tonnes of iron sulphate to the ocean near Antarctica, where iron levels are extremely low. The addition of the missing nutrient prompted a massive bloom of phytoplankton to begin growing within a week. As the phytoplankton, mostly species of diatom, began to die after three weeks, they sank towards the ocean floor, taking the carbon they had incorporated with them.Average Chinese person's carbon footprint now equals European's | Environment | guardian.co.uk

Smetacek said ocean iron fertilisation could bury at most 1 gigatonne of CO2 per year compared to annual emissions of 8-9Gt, of which 4Gt accumulates in the atmosphere.
total Chinese CO2 emissions are now around 80% higher than those of America. This widening gap reflects a 9% increase in total emissions in China in 2011, driven mainly by rising coal use, compared with a 2% decline in the US.Twitter / Amy_NJ: USDA Sec Vilsack on whethe ...
