Florida's climate boosts soil-carbon storage, cuts greenhouse emissions

Sequestration helps mitigate carbon-based gases from getting into the atmosphere. A new study shows Florida's warm, wet climate helps keep carbon in the soil. Soil-stored carbon can slow the build-...

More waters may deserve federal protection, study suggests

Geographically isolated wetlands can be connected in ways that are largely ignored, but that may be critically important for watershed storage and stabilizing downstream flows, researchers say. The...

Coral's best defender against an army of sea stars: Crabs

Coral reefs face a suite of perilous threats in today's ocean. From overfishing and pollution to coastal development and climate change, fragile coral ecosystems are disappearing at unprecedented r...

Space debris expert warns of increasing small satellite collision risk

The increasing number of small 'CubeSat' satellites being launched combined with a relaxed attitude to debris mitigation could lead to hazards for all space users unless preventative measures are t...

Nitrogen fingerprint in biomolecules could be from early sun

The pattern of nitrogen in biomolecules like proteins, which differ greatly from that seen in other parts of the solar system, could have been generated by the interactions of light from the early ...

Causes of California drought linked to climate change

The extreme atmospheric conditions associated with California's crippling drought are far more likely to occur under today's global warming conditions than in the climate that existed before humans...

While the Arctic is melting, the Gulf Stream remains

The melting Arctic is not the source for less saline Nordic Seas. It is the Gulf Stream that has provided less salt. A new study documents that the source of fresher Nordic Seas since 1950 is roote...

Poor fish harvests more frequent now off California coast

In the past 600 years off the California coast, occasional episodes of diminished ocean upwelling that cause fish populations to crash have occurred naturally. The poor yearly fish harvests seen in...

With few data, Arctic carbon models lack consensus

As climate change grips the Arctic, how much carbon is leaving its thawing soil and adding to Earth's greenhouse effect? The question has long been debated by scientists. A new study conducted as p...

If trees could talk: Forest research network reveals global change effects

Permafrost thaw drives forest loss in Canada, while drought has killed trees in Panama, southern India and Borneo. In the U.S., in Virginia, over-abundant deer eat trees before they reach maturity,...
