Temperatures not much warmer than the planet is experiencing now were sufficient to melt a major part of the East Antarctic ice sheet in Earth’s past, scientists reported Wednesday, including during one era about 125,000 years ago when sea levels were as much as 20 to 30 feet higher than they are now.

Climate change could lead to sea level rises that are larger, and happen more rapidly, than previously thought, according to a trio of new studies that reflect mounting concerns about the stability of polar ice.

New research published on Monday finds there is so much wind energy potential over oceans that it could theoretically be used to generate “civilization scale power” — assuming, that is, that we are willing to cover enormous stretches of the sea with turbines, and can come up with ways to install and maintain them in often extreme ocean environments.
[ More ]A large research synthesis, published in one of the world’s most influential scientific journals, has detected a decline in the amount of dissolved oxygen in oceans around the world — a long-predicted result of climate change that could have severe consequences for marine organisms if it continues

The Arctic is so warm and has been this warm for so long that scientists are struggling to explain it and are in disbelief. The climate of the Arctic is known to oscillate wildly, but scientists say this warmth is so extreme that humans surely have their hands in it and may well be changing how it operates.

President Obama moved to solidify his environmental legacy Tuesday by withdrawing hundreds of millions of acres of federally owned land in the Arctic and Atlantic Ocean from new offshore oil and gas drilling.
[ More ]In a massive new study published Wednesday in the influential journal Nature, no less than 50 authors from around the world document a so-called climate system “feedback” of warming soil, especially in the Arctic, that, they say, could make global warming considerably worse over the coming decades.

Four Iranian ships made reckless maneuvers close to a U.S. warship this week, the Pentagon said Thursday, in an incident that officials said could have led to dangerous escalation.
[ More ]As climate scientists nervously watch the Arctic and high latitudes this summer — fearing how 2016’s record warmth could push the delicate system — two new pieces of data showing record rates of Arctic warming are hardly consoling.
[ More ]The list of countries backing Beijing’s stance in the South China Sea just keeps growing, lured by China's growing financial clout, and U.S. hypocrisy over UNCLOS is not helping convince them otherwise.
