Ice sheets were never simple. There is no magic knob that could be turned to optimize melting rates and movement, outside environmental press releases. A new paper in Nature this week shows that not…

Farm runoff and urban pollution in the Hawaiian islands is causing sea turtle tumors, according to a study in PeerJ. The paper by researchers at  Duke University, the University of Hawaii and…

There is less saline in Nordic Seas but that can't be blamed on more Arctic waters due to global warming. Instead, it is that the Gulf Stream has provided less salt.  The Nordic Seas have…

Ice ebbs and flows, that is no secret - but lost in claims that ice is as widespread as ever is the reality that it is now thinner, and the difference is so noticeable the Gravity field and steady-…

Arctic sea ice coverage declined to its annual minimum on September 17th and the National Snow and Ice Data Center (NSIDC) at the University of Colorado, Boulder find that this year's minimum…

In a global warming scenario, large areas of sea ice melt in the summer and when sea ice freezes over in the winter it is thinner and more reduced. But warmer Arctic summers could lead to an…
