Worrying new research finds that the ocean is cutting through a key Antarctic ice shelf.

The Dotson ice shelf holds back two large glaciers and connects to the larger West Antarctic ice sheet.

A new scientific study published Tuesday has found that warm ocean water is carving an enormous channel into the underside of one of the key floating ice shelves of West Antarctica, the most vulnerable sector of the enormous ice continent.

There’s enough wind energy over the oceans to power human civilization, scientists say.

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.

Scientists mapping Greenland have produced some surprising – and worrying – results.

Greenland, the world’s largest island and home to its second largest ice sheet, is a land of ragged cliffs, breathtaking fjords and unimaginable amounts of water on either side of the freezing point. It has also, until now, been something of a mystery.

Scientists may have found a solution to the atmosphere’s methane mystery.

When it comes to climate change, we know where the most important warming agent — carbon dioxide — is coming from. Most of it is coming from the burning of fossil fuels, with additional contributions from deforestation and other causes.

Severe power failures in Puerto Rico and across the Caribbean spur new interest in renewables.

The ongoing electricity disaster in Puerto Rico in the wake of Hurricane Maria — and on several other Caribbean islands slammed at full force by strong storms — is driving new interest in ways of shifting island power grids toward greater reliance on wind, solar and even, someday, large batteries.
