Greenland Melted Recently: High Risk of Sea Level Rise Today

A large portion of Greenland was an ice-free tundra landscape -- perhaps covered by trees and roaming woolly mammoths -- in the recent geologic past (about 416,000 years ago), a new study shows. The results help overturn a previous view that much of the Greenland ice sheet persisted for most of the ...

Important Groups of Phytoplankton Tolerate Some Strategies to Remove CO2 from the Ocean

The Legacy of Past Disturbance Shapes Coastal Forest Soil Stability

Coastal forests are increasingly exposed to the effects of climate change and sea level rise. New experimental research examined how soils change when transplanted between parts of a tidal creek that differed in salinity. Scientists found that soils with a history of salinity and inundation by ...
