Scientists have identified four new man-made gases in the atmosphere that they say are helping to destroy Earth’s protective ozone layer. Writing in Nature Geoscience, the researchers said that there are about 74,000,000 kilograms of three newly identified chlorofluorocarbons (CFCs) – compounds that only contain the atoms of carbon, fluorine and chlorine – and one […]

New evidence suggests climate change is human caused and that if the release of greenhouse gases continues unabated, changes to the world’s climate will greatly exceed those that have taken place so far. The new joint report from the US National Academy of Sciences and the Royal Society, the national science academy of the UK, […]

One of nature’s most beautiful sights is when a monarch butterfly comes fluttering into view. Monarchs are the only known North American butterfly to migrate south for the winter, hibernating and returning in the spring as birds do. However, a new report finds the number of these butterflies hibernating in Mexico reached an all-time low […]

A new study shows changes in precipitation are affected by human activities and can’t be explained by natural phenomena, such as El Niños and La Niñas. Scientists from the Lawrence Livermore National Laboratory in California published the study in the Proceedings of the National Academy of Sciences. The researchers suggest two mechanisms will probably cause […]

As global temperatures rise, so do our levels of hostility and violence, according to a new study. Scientists from the University of California, Berkeley and Princeton University  discovered a strong link between shifts in climate to human violence around the world.  The study found that even minor climate deviations, such as slight changes in normal […]

Arctic Bacterium Offers Clues to Life on Mars

A permafrost microbe has been discovered growing at –15°C, the coldest temperature ever reported for bacterial growth. A team of scientists from Montreal’s McGill University made the discovery on Ellesmere Island, located in the Canadian High Arctic. Researchers said they  found the living strain of bacteria growing in the extreme cold of the  permafrost, which […]

GROVER Robot Provides New tool for Exploring Greenland

NASA‘s newest rover could help scientists better understand changes in the massive Greenland ice sheet. Last summer, higher-than-normal temperatures caused surface melting across about 97 percent of the ice sheet. Scientists expect the robot to detect the layer of the sheet, which is buried beneath two miles of ice, that formed after last year’s extreme […]
