Nature paints a more vivid picture of climate change – and the related changes in ocean currents – by retracing the paths of prehistoric icebergs in the years when the oceans were colder:

Their results show that some of the glacial floodwater running off North America formed a narrow current some 100 kilometres wide […]

Daily Beast has more on how 204 billion tons of melting glaciers have changed the way our planet’s gravity works:

Between 2009 and 2012, the years for which GOCE was taking data, the amount of gravity in Antarctica decreased noticeably, corresponding to a lot of ice melt.

From the point of view of artificial satellites […]

Scientific American watches NASA launch another satellite to watch the way our planet breathes:

But since [David Crisp] first conceived the project nearly 15 years ago, he and other scientists had been eagerly awaiting the opportunity to use this satellite to track the increasingly vast quantities of carbon dioxide humans were emitting. Such information […]
