Despite their rarity, giant icebergs in the Southern Ocean significantly contribute to the reduction of atmospheric carbon by stimulating phytoplankton blooms.
In Iceland, the legacies of volcanoes and glaciers are largely intertwined. As the planet suffers an increasingly climate, a rise in Iceland’s magma levels could spike volcanic activity.
A team of researchers from Yale, Ohio State University, and the University of Copenhagen examined a Peruvian ice core for toxic trace metals, which indicate atmospheric conditions across many years. The scientists found, surprisingly, that Spanish colonial mining in South America caused significant atmospheric pollution prior to the Industrial Revolution.
