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 clima…
For a long time, climate researchers held a glimmer of hope amidst all the gloomy climate predictions: as Antarctica warms and glaciers melt, iron would be released into the sea. This stimulates the bloom of phytoplankton, which absorbs large amounts of CO2 from the atmosphere. But that theory doesn't hold water. Marine scientists at Rutgers University have made the most accurate measurement yet […] Want more science? Read the latest articles on…
