Litter is now found in even the most remote areas of the oceans, say scientists trying to understand how much rubbish is lying at the bottom of Europe's seas. The new study, published in Plos One, shows for the first time that there seems to be no area of the ocean left untouched by human litter. Using 588 video clips collected by unmanned submarine vehicles for geological mapping and marine biology studies, the team found that plastics waste like shopping bags is the most prevalent.

With the focus on reducing carbon emissions, we often forget about methane – another greenhouse gas that is way more powerful as an atmospheric pollutant than carbon dioxide. Methane emissions can come from industry, agriculture, and waste management activities, but can also be emitted from a number of natural sources. One newly discovered natural source: SAR11.

Hay mucho más en tratar de frenar el cambio climático que sólo reducir las emisiones de gases de efecto invernadero. Tecnología, políticas o planes que apuntan a ello también deben tomar en cuenta factores ambientales tales como el consumo de agua. Un enfoque más integral podría tener algunas opciones mucho más atractivas que otras, especialmente cuando se implementa en los países áridos, tales como Australia, sugieren Philip Wallis y sus colegas de la Universidad de Monash en Australia, en un artículo en la revista de Springer Climatic Change.

Recently scientists from the Zoological Society of London and Yale University assessed the world's 9,993 bird species according to their evolutionary distinctiveness and global extinction risk. At number three on the list is the Critically Endangered California condor (Gymnogyps cali­fornianus) - weighing as much as 25 pounds, standing over four foot tall, with a wingspan of almost 10 feet, it is the largest land bird in North America.

A long-term study of the links between climate and marine life along the rapidly warming West Antarctic Peninsula reveals how changes in physical factors such as wind speed and sea-ice cover send ripples up the food chain, with impacts on everything from single-celled algae to penguins.
