Iron-Rich Dust From South America Played Role in Last Two Glacial Periods, Says Study

Dust from the land that gets blown into the ocean appears to influence natural climate swings. A new study looks into where much of that dust came from in the past 260,000 years.

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.
