Fossil carbon dioxide emissions increased by 40 percent from 1990 to 2008, according to new findings. Coal has bypassed oil as the largest source of CO2 emissions.

Scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight -- creatures that somehow manage a living in a frigid black world down to 5000 meters (three miles) below the ocean waves.

Scientists have found for the first time that high pressure can be used to make a unique hydrogen-storage material. The discovery paves the way for a new approach to the hydrogen-storage problem. The researchers found that the normally nonreactive, noble

Understanding mixing in the ocean is of fundamental importance to modeling climate change or predicting the effects of an El Niño on our weather. Modern ocean models primarily incorporate the effects of winds and tides. However, they do not generally

Scientists have shown how a family of genes (1-aminocyclopropane-1-carboxylate synthase, or ACS genes), in the weed Arabidopsis thaliana, are responsible for production of ethylene. This gas affects many aspects of plant development, and this information, which will be applicable to

Biogeochemistry and geology and geophysics scientists have returned from Arctic expedition exploring methane hydrate deposits in the Beaufort Sea and spatial variation of sediment contribution to Arctic climate change.

In order to avoid dangerous consequences for the earth's ecosystems, global emissions must peak around 2015, and they need to be cut by half between the peak and 2030, according to new findings.
