Cave Deposits Reveal a Permafrost-Free Arctic
Mineral cave deposits from northern Siberia show that the region was permafrost free during the late Miocene period, when Earth was warmer than today.
As the Arctic Warms, Soils Lose Key Nutrients
Climate change heats not only the air and the ocean but also the soil, where key processes that determine fertility and carbon sequestration operate in a fine-tuned balance.
Warming Winters Sabotage Trees’ Carbon Uptake
In temperate forests, the biomass-building benefits of warmer growing seasons are offset by damaging variability in winter weather—a disparity that climate models may miss.
Southern Ocean Salinity May Be Triggering Sea Ice Loss
New satellite technology has revealed that the Southern Ocean is getting saltier, an unexpected turn of events that could spell big trouble for Antarctica.
First Species-Level Assessment Reveals Extinction Risk in Mesoamerica
Forty-six percent of tree species in Mesoamerica are threatened with extinction. Researchers hope a new regional study will inform targeted conservation strategies.
New Research Shows More Extreme Global Warming Impacts Looming for the Northeast
One new study identifies a 17% increase in the destructive potential of the strongest nor’easters, while another bolsters links between Arctic ice melt and dangerous blizzards.
Artificial Light Lengthens the Urban Growing Season
New research shows that artificial light at night lengthens the plant growing season in cities, overshadowing the effect of high urban temperatures.
Machine Learning Model Flags Early, Invisible Signs of Marsh Decline
Decreases in underground plant biomass could signal future marsh loss and prompt conservation measures.
Whaling Records Can Help Improve Estimates of Sea Ice Extent
The locations of humpback whale catches in the early 20th century indicate that most climate models overestimate the historic extent of sea ice in the Southern Ocean.
