Battery can be recharged with carbon dioxide

(Phys.org)—Researchers have developed a type of rechargeable battery called a flow cell that can be recharged with a water-based solution containing dissolved carbon dioxide (CO2) emitted from fossil fuel power plants. ...

Global fossil-fuel emissions could decline in 2015, study finds

Annual global carbon dioxide emissions from fossil fuels could drop slightly in 2015, according to a report from the Global Carbon Project led by a Stanford University researcher. This surprising result contrasts with the ...

Cutting emissions gradually will avert sudden jump in warming

Reducing fossil fuel emissions steadily over coming years will prevent millions of premature deaths and help avoid the worst of climate change without causing the large spike in short-term warming that some studies have predicted, ...

Would a carbon tax help to innovate more-efficient energy use?

Taxing carbon emissions would drive innovation and lead to improved energy efficiency, according to a new paper published in Joule from Carnegie's Rong Wang (now at Fudan University), Harry Saunders, and Ken Caldeira, along ...

415.26 parts per million: CO2 levels hit historic high

Scientists in the United States have detected the highest levels of planet-warming carbon dioxide in Earth's atmosphere since records began, sounding new alarm over the relentless rise of man-made greenhouse gas emissions.
