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.

Iron Fertilization Won’t Work in Equatorial Pacific, Study Suggests
Over the past half-million years, the equatorial Pacific Ocean has seen five spikes in the amount of iron-laden dust blown in from the continents. In theory, those bursts should have turbo-charged the growth of carbon-capturing algae, but a new study shows that the excess iron had little to no effect.
