Previous Climatic Shifts Deprived Oceans of Oxygen

Jan 30th, 2015 | By

Dead zones — massive stratified columns of oxygen-deprived water — could become the new normal in oceans around the world as global temperatures continue to rise. New research, published this week in the journal PLOS ONE, links ancient climate change to dead zone expansion. “Our modern ocean is moving into a state that has no

As components of the global cryosphere, mountain glaciers are known for their high sensitivity to climate change. Glaciers are the result of solid precipitation and reflect its variability from one year to the next. The ablation process – by which glaciers lose snow and ice, converting it into water and vapor – depends directly on
