Raising Central American Orography Improves Climate Simulation
Elevation of Central American orography significantly reduces the pervasive tropical rainfall bias by blocking the easterlies and consequently warming the northeastern tropical Pacific.

Evidence of Crevasses Transporting Heat Deep into Greenland Ice
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?

Severe Radiation Storms Pose Health Risk to Air Travel
Simulations of radiation storm fluxes on real flight paths highlight how severe space weather could expose aircrew and passengers on busy transatlantic routes to significant radiation doses.
