Sediment measurements show that flow alterations and discharges are driving increasing concentrations of multiple heavy metals in the Nile Delta, threatening ecosystems, agriculture, and human health.
Suivie de l’accumulation des métaux lourds dans le Delta du Nil
Les analyses de sédiments montrent que la réutilisation de l’eau non traitée et la construction de barrages entraînent l’augmentation des concentrations de métaux lourds dans le Delta du Nil, menaçant gravement les écosystèmes, l’agriculture et la santé humaine.
Why Tropical Forests Are Important for Our Well-Being
Tropical forests play a critical role in supporting human well-being, food security, and the maintenance of biodiversity.
Glacial Ice Offers Polar Bears a Precarious Climate Refuge
An isolated polar bear population in southeastern Greenland survives in fjords, despite spotty sea ice. But this pocket of bears is not a sign of how the species could be saved.
Warmer Winters Keep Crops Sleepy into Spring, Hurting Yield
Annual crops go dormant during winter. Frosty temperatures cue them to wake up—but the warmer winters brought on by climate change scramble the cold signal, hurting yield.
Rain Makes Skulls Bigger—in Mice
New research shows how regional weather, shaped by towering mountain ranges, might influence the size and shape of local rodents.
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.
Emil Cherrington: Bringing Satellite Data Down to Earth
Showing how eyes in the sky can help people on the ground.
Understanding the Importance of Salt Marshes
Hydrological processes affect plant ecology and the biogeochemical exchange between salt marshes and the sea.
After a Hurricane, Coastal Systems Draw a Line in the Sand
A new study finds nature can’t have it both ways: On the basis of thousands of case studies from dozens of hurricanes, there’s always a trade-off between resistance and resilience.
