Climate models are evolving, and are getting more accurate, but they are still incomplete. Our atmosphere is very complex, and there are factors that even current models don’t address, or address with an in-complete knowledge of the physical processes involved. This leads to inaccuracies that create uncertainty in the results of climatic projections. (more…)
Researchers found high levels of radioactivity, metals, and salts in sediments and water downstream from a Pennsylvania facility that treats fracking wastewater. Radioactivity levels downstream of the treatment plant were about 200 times higher than in surrounding areas, and concentrations of some salts and metals were also higher than background levels, (more…)

We know that pollution is bad for us, don’t we? And we guess that living in areas with high levels of pollution is probably not good for our health, but we need to live near our job, and populated areas offer more employment opportunity, recreational and cultural opportunities and other advantages. But at what cost? And what can we do to reduce the levels of (more…)
The increasing acidification of the world’s oceans caused by rising concentrations of atmospheric carbon dioxide not only poses a threat to marine creatures, but also could lead to an intensification of planetary warming, according to a new study.
A team of U.S., British, and German researchers (more…)
Commenting on Monday’s ruling by a federal judge in Anchorage that Shell’s oil spill plans for drilling in Alaska’s Beaufort and Chukchi seas don’t violate environmental laws, Greenpeace International Arctic campaigner Ben Ayliffe said:
