Carbon dioxide stored underground can find multiple ways to escape

When carbon dioxide is stored underground in a process known as geological sequestration, it can find multiple escape pathways due to chemical reactions between carbon dioxide, water, rocks and cement from abandoned wells, according to Penn State researchers. The researchers investiga

Land surfaces are storing more water slowing sea level rise

<!– –> New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise. A new study by scientists at NASA’s Jet P

Climate change will delay transatlantic flights

Planes flying between Europe and North America will be spending more time in the air due to the effects of climate change, a new study has shown. By accelerating the jet stream – a high-altitude wind blowing from west to east across the Atlantic – climate change will speed up eastboun
