Crevasses are a feature of ice sheets but how deep they extend has been a mystery. Now crevasse traces have been visually identified to 265 meters in a borehole in a fast-moving outlet glacier.

What’s the Beef About Methane?
Progress has been made to reduce methane emission intensity from livestock (the amount of methane per unit of protein), but where are the greatest opportunities to reduce this methane source further?

Was the AD 365 Mediterranean Earthquake Normal?
The great AD 365 earthquake at Crete has implied a locked Hellenic subduction zone that can produce more earthquakes to threaten Mediterranean coastlines. But what if wasn’t a subduction zone event?
