Short-Lived Solutions for Tall Trees in Chile’s Megadrought
Some southern beeches in the Andes have plumbed deeper for moisture as the surface has dried up. But doing so may deplete resources and undermine the trees’ future health.
Coral Chemistry Reflects Southeast Asia’s Economic Expansion
Soil erosion from economic development sent sediments into the South China Sea—and into coral skeletons.
Munching Moose Cool Forest Floors
By making clear-cut forests patchier, moose create a reflective surface that bounces back sunlight and keeps temperatures down.
The World’s Roots Are Getting Shallower
Root-filled soils are hot spots of nutrient cycling and carbon storage. New research finds that the world has lost millions of cubic meters of rooted soil volume—and we’re on track to lose much more.
Satellites Can Accurately Take Earth’s Temperature
Satellite-based measurements of land surface temperature may prove to be an essential pairing with near-surface air temperatures to understand global warming and cooling trends.
Plants Need a Lot of Power to Pump Sap
A novel calculation reveals how much power plants need to move water through their stems—and how plants gain energy from the process.
New Map of Proposed Mantle-Driven Topography Stirs the Pot
The role the deep Earth plays in creating topography is hotly debated. A new study uses subtle elevation changes around the globe as evidence that the mantle plays a key role in building topography.
Plant-Nibbling Insects May Make It Cloudier and Cooler
Insects that eat plant leaves could change the local atmosphere, but current climate models do not account for this impact.
