As much as 44 billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost could be released into the environment over the next century by the effects of global warming.
The environmental benefits of biofuels are being systematically overestimated, says a University of Edinburgh scientist.
Plants may thrive in the initial stages of global warming - but not for long. A study from Northern Arizona University shows that any improvements in growth caused by climate change disappear within ten years.
North American forests might be more use than expected at slowing the pace of climate change.
Researchers have discovered that forest trees can tap into the nitrogen found in rocks, boosting their growth and allowing them to take up more carbon dioxide from the atmosphere.
Our sun and its inner planets may not have formed from the same materials, as previously thought, samples returned by NASA’s Genesis mission indicate.
Two of the Air Force’s Thunderbirds aerial team members recently flew their F-16s in a Department of Defense aerial team show running on a blend of camelina-based biofuel and regular jet fuel.
Ammonia brought to Earth by meteorites could have helped kick-start life, says a team at Arizona State University.
Scientists have created organic macromolecules by zapping a Titan-like atmosphere with UV rays. The discovery supports the idea that the moon of Saturn could support life.
