A Major Glacier is Undermined From Below

Seven days and eleven flights after we arrived in Alaska, we finished deploying our seismic stations onshore. Our final constellation of stations differs a little from our original plan (as always happens with field work), but achieves our main goal of instrumenting the part of the Alaska Peninsula that is nearest to our planned offshore…

Climate Change Lawsuit Against Utilities Rejected by U.S. Supreme Court, Bloomberg, June 20 States can’t invoke federal law to force utilities to cut greenhouse-gas emissions, the U.S. Supreme Court ruled, shutting off one avenue for groups that advocate bolder steps against climate change. The unanimous ruling is a victory for five companies — American Electric…

Corporate giant Fiji Water makes millions of dollars every year selling bottled water, but only 47 percent of Fiji Islanders have access to clean drinking water. That may change.

This morning we left Arequipa and the comforts of the tourist trail, driving east across the puna towards the Andes proper. Our route took us along the newly constructed Caraterra Interoceanica – a highway linking the Pacific coast of Peru to ports in Brazil – and up to elevations of 4700 m. Along the way…

“If crops don’t adapt to climate change, neither will agriculture, and neither will we,” said Cary Fowler of the Global Crop Diversity Trust at the 2009 TED conference. Climate change is already affecting food supplies around the world as heat waves and drought reduce grain harvests and food prices soar. For every 1˚ C rise above…

What a difference a day makes! We’ve said goodbye to the sprawling metropolis of Lima and now are happily settled in Arequipa – the White City. This name refers to the white sillar rock used in the construction of the old colonial city and which is in fact a pyroclastic deposit from the volcanoes towering…

Every field location comes with logistical hurdles, and the Alaska Peninsula is no exception. Weather, wildlife and modes of transport pose the greatest challenges. We are hardly the first scientists to encounter these: Lamont-Doherty Earth Observatory has a long, rich history of collecting seismic data in this region (e.g., Shumagin Seismic Network, which ran for…
