Warmer summers in the far Northern Hemisphere are disrupting weather patterns and triggering more severe winter weather in the United States and Europe, a team of scientists say, in a finding that could improve long-range weather forecasts. Blizzards and extreme cold temperatures in the winters of 2009/10 and 2010/11 caused widespread travel chaos in parts…

Atmospheric levels of methane, 20 times more powerful than carbon dioxide (CO2) at trapping heat, stayed steady for two decades to 2006 on wider fertilizer use to grow rice or a surge in natural gas demand, according to two separate studies in the journal Nature. Climate researcher Fuu Ming Kai from the Massachusetts Institute of…

Scientists are outfitting elephant seals and self-propelled water gliders with monitoring equipment to unlock the oceans’ secrets and boost understanding of the impacts of climate change. Oceans regulate the world’s climate by soaking up heat and shifting it around the globe. They also absorb huge amounts of planet-warming carbon dioxide, acting as a brake on…
