Defying Some Expectations, Southern Ocean Did Not Increase Carbon Uptake in Ice Ages
In much of the world ocean, there is evidence that iron-rich dust blowing from land has fertilized algae during cold period, increasing uptake of carbon from the air, and keeping things frigid. Not here, says a new study.
