Bowing to pressure from environmental groups, the German science ministry has suspended a planned ocean fertilization experiment in the Southern Ocean and asked the researchers to commission an independent analysis of the project’s environmental impact before dumping anything in the ocean.

A team of UK scientists have discovered a natural process that could delay, or even end, the threat of global warming.

The researchers, aboard the Royal Navy’s HMS Endurance, have found that melting icebergs off the coast of Antarctica are releasing millions of tiny particles of iron into the southern Ocean, helping to create huge ‘blooms’ of algae that absorb carbon emissions. The algae then sinks to the icy depths, effectively removing CO2 from the atmosphere for hundreds of years.

According to lead researcher, Prof. Rob Raiswell of Leeds University, “The Earth itself seems to want to save us.”

Can selling carbon credits to finance “ocean fertilization” solve global warming?

Greenpeace calls it “irresponsible” but, a variety of companies including, Climos, a San Francisco start-up, have raised a enough venture capital to give it a try. By drizzling an iron slurry across a stretch of ocean the company will leave a bloom of phytoplankton in its wake and hopefully take a small step toward solving global warming.
