A new synthesis published in Nature suggests that thawing Arctic permafrost will release greenhouse gases gradually, rather than in a sudden "bomb". The gradual rate of these natural emissions may give society more time to adapt to their effects, but they remain a challenge for climate mitigation.

The global water cycle is tied closely to climate change, agricultural practices, land use, and the environment—sometimes through complex, multi-way interactions. NSF and USDA together have awarded $25 million in research grants to find out what this means for the sustainability of Earth’s water resources.

In front of the United States Geological Survey (USGS) national headquarters building in Reston, Va., two genetically identical lilac bushes are rooted in the earth. To casual observers, they are fragrant adornments to the landscaped property. But to ecologist Jake Weltzin and geographer John Jones—USGS scientists who study plant and animal life-cycle events—they are “Li” and “Lac,” two small but important pieces of a developing climate change indicator system.

A new study concludes that the current rate of ocean acidification is higher than at any time in at least the last 300 million years and attributes this ecosystem-threatening change to the huge quantities of carbon dioxide being released into the atmosphere from fossil-fuel burning and deforestation.
