Pope Francis’s broad-ranging encyclical warns that we are destroying our common home and face an immense and urgent challenge to protect it. But it goes far beyond just the subject of climate change, calling for a holistic and sustainable future.

Antarctica’s Retreating Ice

While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and this trend shows no sign of slowing, meaning the implications for global sea level rise in this century could be more dramatic than earlier projections anticipated.

Glacial Earthquakes May Help Forecast Sea-Level Rise

Glacial earthquakes are produced as massive ice chunks fall off the fronts of advancing glaciers into the ocean. A new study of the quakes’ mechanics may give scientists a way to measure ice loss remotely and refine predictions of sea-level rise.

In a study published last week, Lamont post-doctoral scholar Heather Ford and coauthors used 4 million-year-old fossils from the Pliocene to reconstruct the physical features of the Pacific Ocean that would have shaped the environment during a critical juncture in Earth history.

Students throughout Columbia University were notified of a once-in-a-lifetime chance to attend a student simulation in anticipation of the upcoming United Nations Climate Conference in Paris. Two words jumped out at me immediately: climate and Paris.

In a Melting Iceland, Drilling Deep to Stem Climate Change

Underground, carbon dioxide disperses through volcanic basalt, and solidifies into a substance similar to limestone. A geologist shows off a core taken from the injection zone.

Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.

Iceland has a complicated relationship with climate change. As in much of the far north, global warming is already exerting many effects here–arguably both good and bad. Yet the country contributes relatively little to the warming, since most of its energy comes from geothermal and hydro plants, which produce little carbon dioxide. Now, it is on the scientific cutting edge of the issue.

Creating a ‘Safe Space’ for Iconic Ecosystems

Important global ecosystems like the Amazon rainforest and Great Barrier Reef are in danger of breaking down because of a combination of local pressures and climate change, but better local management could help make these areas more resilient.
