Increase in volcanic eruptions at the end of the ice age caused by melting ice caps and glacial erosion
The combination of erosion and melting ice caps led to a massive increase in volcanic activity at the end of the last ice age, according to new research published in Geophysical Research Letters.

Study shows North Atlantic Ocean carbon storage doubled over last decade
A new study shows that the North Atlantic Ocean absorbed 100 percent more man-made carbon dioxide over the last decade, compared to the previous decade. The findings show the impact that the burning of fossil fuels have had on the world's oceans in just 10 years.

Fossils are not just for dinosaurs anymore
According to a new study published in Geophysical Research Letters, earthquakes leave behind fossils too.

New landslide videos: Aconcagua (again), Muothatal and Pacifica
Dave Petley, of the Landslide Blog, presents new video of another Aconcagua landslide from an earlier debris flow, collected on 26th December 2015. "This video beautifully illustrates that dry nature of these types of flow, even though they look wet," writes Petley.
