Nitrogen released into the soil from thawing permafrost in the Arctic could accelerate soil carbon decomposition and alter carbon dynamics, with global implications.Read More »Biogeosciences
Ocean animals at the top of the food chain recovered first after a cataclysm at the end of the Permian period. The extinction was triggered by events resembling the changes brewing in today's oceans.Read More »Biogeosciences
As the climate warms, tropical birds living in the mountains are retreating to higher elevations to avoid the heat. What happens when they run out of mountain slope to escape to?Read More »Biogeosciences
A new study reveals phytoplankton spring blooms in the Arctic Ocean, which were previously nonexistent, are expanding northward at a rate of 1 degree of latitude per decade.Read More »Biogeosciences
River systems are affected by societies against a backdrop of climate change. A new dataset reveals how these forces affect river flow, chemistry, and the biological health of the river.Read More »Biogeosciences
As spring snowmelt and fall rains inundate northern hardwood forests with moisture, soil bacteria get moving and increase carbon exports to the atmosphere and into nearby water bodies.Read More »Biogeosciences
Clear air policies have led to dramatic reductions in acid rain and improved ecosystem health, but it now appears that climate change could counteract those gains.Read More »Biogeosciences
