SD A major climate hope in Antarctica just melted away

[admin]

A popular climate theory suggested that melting Antarctic glaciers would release iron into the ocean, sparking algae blooms that pull carbon dioxide from the air. New field data from West Antarctica reveal that meltwater provides far less iron than scientists once believed. Instead, most of the iron comes from deep ocean water and sediments, not from the melting ice itself. The discovery raises new questions about how Antarctica influences climate change.
