Remember Planktos, the company that was going to sail into the Atlantic ocean and dump a bunch of iron ore, hoping it would stimulate CO2 absorption and profit the company via carbon offsets?

Well, Andy Revkin brings news that the company has set sail. Guess the cat’s out of the bag!

(Planktos has been criticized on Gristmill here, here, here, here, here, and by a group of Greenpeace scientists here. Planktos CEO Russ George defended the company here.)
