Deep Ocean Current May Slow Due To Climate Change

Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe. A new study has found that recent climate change may be acting to slow down one of these conveyer belts, with potentially serious consequences for the future of the planet’s climate.

Iron Increase In Oceans And Correlated Decrease Of CO2 Levels? A Study

Researchers from Princeton University and the Swiss Federal Institute of Techonology in Zurich have confirmed that during the last ice age iron fertilization caused plankton to thrive in a region of the Southern Ocean. Iron fertilization has also been suggested as one way to draw down the rising levels of CO2 associated with the burning of fossil fuels.

U.S. Scientists Launch Wake-Up Campaign on Climate Change

In an unusual intervention in policy debates, the American Association for the Advancement of Science (AAAS) warned Tuesday that the world was “at risk of pushing our climate system toward abrupt, unpredictable, and potentially irreversible changes with highly damaging impacts.”
