Sunlight stimulates release of climate-warming gas from melting Arctic permafrost, study says
Ancient carbon trapped in Arctic permafrost is extremely sensitive to sunlight and, if exposed to the surface when long-frozen soils melt and collapse, can release climate-warming carbon dioxide gas into ...
Study: Amazon deforestation brings loss of microbial communities
An international team of microbiologists led by Klaus Nüsslein of the University of Massachusetts Amherst has found that a troubling net loss in diversity among the microbial organisms responsible for a ...

Earth still absorbing about half carbon dioxide emissions produced by people: study
Earth's oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a study ...
New model suggests ocean pH falling more rapidly
Evidence of impending tipping point for Earth uncovered
A prestigious group of scientists from around the world is warning that population growth, widespread destruction of natural ecosystems, and climate change may be driving Earth toward an irreversible change ...

New technology uses solar UV to disinfect drinking water
(PhysOrg.com) -- A team of Purdue University researchers has invented a prototype water-disinfection system that could help the world's 800 million people who lack safe drinking water.
Switching from coal to natural gas would do little for global climate, study indicates
Although the burning of natural gas emits far less carbon dioxide than coal, a new study concludes that a greater reliance on natural gas would fail to significantly slow down climate change. The study appears ...
Methane levels 17 times higher in water wells near hydrofracking sites
A study by Duke University researchers has found high levels of leaked methane in well water collected near shale-gas drilling and hydrofracking sites. The scientists collected and analyzed water samples from 68 private ...
Fracking leaks may make gas 'dirtier' than coal
(PhysOrg.com) -- Extracting natural gas from the Marcellus Shale could do more to aggravate global warming than mining coal, according to a Cornell study published in the May issue of Climatic Change Letters (105:5).
