Prepare yourselves for radical unintended consequences if these scientists manage to convince governments to go along with their plan. Alastair Doyle reports for Reuters via the Christian Science Journal:
Dumping iron in the seas can help transfer carbon from the atmosphere and bury it on the ocean floor for centuries, helping to fight climate change, according to a study released on Wednesday.
The report, by an international team of experts, provided a boost for the disputed use of such ocean fertilisation for combating global warming. But it failed to answer questions over possible damage to marine life.
When dumped into the ocean, the iron can spur growth of tiny plants that carry heat-trapping carbon to the ocean floor when they die, the study said.
Scientists dumped seven tonnes of iron sulphate, a vital nutrient for marine plants, into the Southern Ocean in 2004. At least half of the heat-trapping carbon in the resulting bloom of diatoms, a type of algae, sank below 1,000 metres (3,300 ft)…
