Enormous pit of melting carbon the size of Mexico discovered under US — RT America
A reservoir of melting carbon covering an area almost the size of Mexico has been discovered beneath the western US, casting doubt over previous estimates of carbon levels inside the Earth. ...
Scientists Accidentally Discover Efficient Process to Turn CO2 Into Ethanol
The process is cheap, efficient, and scalable, meaning it could soon be used to remove large amounts of CO2 from the atmosphere.
Part microbe, part machine: Bionic leaf sucks up carbon dioxide as it makes liquid fuel
A team of scientists at Harvard University says it has come up with a bionic leaf — a system that could use solar power and hydrogen-eating bacteria to generate liquid fuel. The findings, described in...
Climate Change Could Force 100M Into Poverty By 2030, World Bank Group Report Says
There could be more than 100 million additional people living in extreme poverty by 2030 if the international community does not undertake rapid, inclusive and climate-smart development, a World Bank ...
Global Carbon Dioxide Levels Topped 400 PPM Throughout March In Unprecedented Milestone
Average global levels of carbon dioxide stayed above 400 parts per million, or ppm, through all of March 2015 -- the first time that has happened for an entire month since record keeping first began,
Scientists Seeking to Save World Find Best Technology Is Trees
(Bloomberg) -- Oxford University scientists, after a year of research, have determined the best technology to suck carbon dioxide from the atmosphere and try to reverse global warming. It’s trees.
German company can make gasoline from water and airborne CO2
The challenge of assembling airborne carbon gases into liquid hydrocarbon fuels has remained elusive, with most actual progress coming thanks to intermediate carbon-fixers like algae. Now, though, a G...
