Scientists have found that permafrost buried beneath the Arctic Ocean holds 60 billion tons of methane and 560 billion tons of organic carbon — making it a major source of greenhouse gases not currently included in climate projections that could have a significant impact on climate change in the longer-term.

Scientists have little understanding of the role fishes play in the global carbon cycle linked to climate change, but a Rutgers-led study found that carbon in feces, respiration and other excretions from fishes – roughly 1.65 billion tons annually – make up about 16 percent of the total carbon that sinks below the ocean’s upper layers.

A study recently completed in Europe and North America indicates that the composition of wintering and breeding bird communities changes in line with global warming. 

A new study finds that California’s commuters are likely inhaling chemicals at levels that increase the risk for cancer and birth defects.

A postdoctoral researcher at the University of Oregon has shown that linking pollen records to plant traits works to reconstruct the benefits ecosystems provide for humans.

A new USC study puts ocean microbes in a new light with important implications for global warming.

A geologist’s dream, Gros Morne National Park is one of the few places where you can set foot on the Earth's mantle without digging an inch.

There are hundreds of thousands of oval depressions dotting the Atlantic coastal plain—relicts of a cooler, drier, windier time.

Polar sea ice coverage was below average for the month

Researchers find some US forests add to global warming
