The oldest and thickest sea ice in the Arctic has started to break up, opening waters north of Greenland that are normally frozen, even in summer. This phenomenon – which has never been recorded before – has occurred twice this year due to warm winds and a climate-change driven heatwave in the northern hemisphere.

The U.S. and its NATO allies have warned that an uptick in Russian submarine activity near undersea fiber optic cables means Moscow may be plotting to disrupt or intercept sensitive or other critical internet communications in the event of a confrontation with the West.
[ More ]New regulations could open the door for sustainable mining, says the head of the International Seabed Authority. However, he and others pointed to environmental, financial, and technical challenges.

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 ]Top US and Chinese military commanders have signed a deal to improve communications between the two forces amid ongoing disputes in the South and East China seas.
