Arctic Atmospheric Circulation, Freshwater and Sea Surface Height

NASA 2012: The transpolar drift (purple arrows) is a dominant circulation feature in the Arctic Ocean that carries freshwater runoff (red arrows) from rivers in Russia across the North Pole and south towards Greenland. Under changing atmospheric conditions, emergent circulation patterns (blue arrows) drive freshwater runoff east towards Canada, resulting in freshening of Arctic water…

Large Underwater Methane seeping Structures can collapse

Ocean oxygen falling two to three times faster than predicted

The trend of oxygen falling is about two to three times faster than what we predicted from the decrease of solubility associated with the ocean warming.

Peru Flooding Disaster Footage Compilation (March 2017)

“We are confronting a serious climatic problem,” said Peru’s president, Pedro Pablo Kuczynski, in a broadcast to the nation on Friday afternoon. “There hasn’t been an incident of this strength along the coast of Peru since 1998.” The disaster – which came after a period of severe drought – has been blamed on abnormally high…

Making Water Filtration Less Harmful to the Environment

In the aftermath of Hurricane Sandy in 2012, the U.S. East Coast faced a water crisis. The torrential rains had contaminated drinking water sources with millions of gallons of sewage water. Naturally, the authorities tried to disinfect the water with chlorine. Chlorine, traditionally, has been good at killing microorganisms. More recently, however, scientists have discovered…
