Global Warming Could Trigger the Next Ice Age

Source: Science Daily - Top NewsScientists have uncovered a gap in Earth's carbon cycle that could cause global warming to overshoot into an ice age. As the planet warms, nutrient-rich runoff could fuel plankton growth that buries huge amounts of carbon in the ocean. In low-oxygen conditions, this process can spiral out of control, cooling Earth far beyond its original state. While this cooling won't save us from modern climate change, it may explain Earth's most extreme...
