Scientists are Concerned about Mysterious Rise in Ocean Salinity

Scientists have observed unexpected changes in the seawater salinity and they are increasingly concerned about the potential impact on ocean currents.  The salinity of seawater can accelerate the water cycle which can cause extreme weather events like floods and drought. To investigate the issue of ocean salinity scientists have boarded the research vessel Knorr, which set sail on September 6, 2012. NASA’s…

The Oceanic Conveyor Belt: Climate Change Tipping Points Being Reached in the Arctic, Western Boundary Ocean Currents

Two new research papers by authoritative climate research teams were announced this week — one on climate change tipping points being reached in the Arctic and a second on warming of long-distance, poleward-moving ocean currents. The results of the studies show that warming of both the Arctic and western boundary currents is happening faster than has been anticipated, prompting the…

Shifting currents are eating away at the Pine Island Ice Shelf

Shifting Ocean Currents Drive Accelerating Ice Melt of Antarctic Ice Shelf

Shifting ocean currents appear to be accelerating ice melt of the Pine Island Glacier Ice Shelf in western Antarctica. According to research published this week in the journal Nature Geoscience, scientists from the Lamont-Doherty Earth Observatory at Columbia University have recorded ocean currents driving at and underneath the ice shelf, carving out an expanding cavity from underneath the glacier, creating…
