Tree swallows in the northern U.S. and Canada face the greatest risk from climate change despite responding to temperature the same way as tree swallows in the southern U.S, according to a new study led by Cornell researchers that analyzed nearly 95,000 nests across five decades.
Could Geoengineering Work to Tamp Down Super El Niños?
With an anticipated “super” El Niño looming, a new study led by UC San Diego’s Scripps Institution of Oceanography considers whether society could use a weather-altering technique as a tool to mitigate the floods, extreme heat and other events that El Niño would bring.
Slowing Atlantic Current Fueling Stronger California Storms
A slowing Atlantic Ocean current is projected to intensify powerful storms in California while reducing snowfall over Greenland, according to a new University of California, Riverside study.
Ancient DNA reveals the mysterious collapse of Europe’s megalith builders
DNA from a 5,000-year-old French megalithic tomb reveals that the people buried before and after a population collapse were genetically unrelated, pointing to a major migration after a devastating crisis. The shift coincided with new social traditions and the disappearance of the communities that built Europe's giant stone monuments.
Bumblebees collect up to 7 times more toxic metals than honeybees
Bumblebees are picking up dramatically more toxic heavy metals than honeybees, even when both species forage in the same places. Researchers warn that this hidden pollution could quietly reduce their ability to find food, reproduce, and keep colonies healthy.
How the Great Barrier Reef Survived Through 30,000 Years
A landmark study used ancient reef cores to deliver insight into the reef's responses to sea-level shifts.
Human Activity Has Driven Retreat of Antarctica’s Fastest Melting Glacier
The first study to directly attribute Antarctic glacier retreat to climate change shows Pine Island Glacier was pushed significantly further by human driven warming.
European Cities Short on Shade as Heat Bites
New analysis of 5.5 million buildings shows 84% fall short of tree canopy levels required for meaningful cooling.
Climate Change May Prop Up Urban Plant Growth in the Face of Development — Provided Cities Build Slowly Enough
Researchers find a “critical speed limit” of urban development for maintaining plant communities amid climate change.
Honeybee Queens Push Pesticides to Eggs to Protect Themselves Over Their Offspring
Worker bees are the first line of defense when it comes to removing contamination in honeybee colonies, but a queen has her ways, too.
