How do you forecast eruptions at volcanoes that sit ‘on the cusp’ for decades?

Credit: CC0 Public Domain Some volcanoes take their time—experiencing protracted, years-long periods of unrest before eventually erupting. This makes it difficult to forecast when they pose a danger to their surrounding areas, but Carnegie’s Diana Roman and Penn State’s Peter LaFemina are trying to change that. “Dormancy, brief unrest, eruption—this is a familiar pattern for […]

The California coast is disappearing under the rising sea: Our choices are grim

Credit: CC0 Public Domain The California coast grew and prospered during a remarkable moment in history when the sea was at its tamest. But the mighty Pacific, unbeknownst to all, was nearing its final years of a calm but unusual cycle that had lulled dreaming settlers into a false sense of endless summer. Elsewhere, Miami […]

But could this effect be intentionally recreated to fight climate change? A new paper in Geophysical Research Letters […]

Study shows improved estimates of Brazilian Amazon gains and losses

Credit: OU A University of Oklahoma-led study generated improved annual maps of tropical forest cover in the Brazilian Amazon in 2000-2017 and provided better characterization on the spatio-temporal dynamics of forest area, loss and gain in this region. The Amazon basin has the largest tropical forests in the world. Rapid changes in land use, climate […]
