A new study published Jan. 8 in the journal Nature Geoscience reveals that strong El Niño events can cause significant ice loss in some Antarctic ice shelves while the opposite may occur during strong La Niña events.

Scientists at the University of Dundee have discovered that E. coli bacteria could hold the key to an efficient method of capturing and storing or recycling carbon dioxide.

Cutting carbon dioxide (CO2) emissions to slow down and even reverse global warming has been posited as humankind’s greatest challenge. It is a goal that is subject to considerable political and societal hurdles, but it also remains a technological challenge.

Human activities are exposing US rivers and streams to a cocktail of salts, with consequences for infrastructure and drinking water supplies. So reports a new study in the Proceedings of the National Academy of Sciences that is the first to assess the combined, long-term changes in freshwater salinity and alkalization across the country.

Methane hydrates, also known as flammable ice, occur in many regions of the oceans. But only under high pressure and cold temperatures the product of methane and water forms a solid compound. If the pressure is too low or the temperature is too high, the hydrates decompose, and the methane is released as gas from the sea floor into the water column. Spitsbergen has been experiencing severe outgassing for several years. Does the methane originate from decomposed methane hydrates? What is the cause of the dissociation of the hydrates? Warming due to climate change or other, natural processes? An international team of scientists has now been able to answer this question, which has been published in the international journal Nature Communications.

Birds exposed to the persistent noise of natural gas compressors show symptoms remarkably similar to those in humans suffering from post-traumatic stress disorder, new research shows.
