Scientists at the University of Dundee have discovered that E. coli bacteria could hold the key to an efficient method of capturing and storing or recycling carbon dioxide.

Cutting carbon dioxide (CO2) emissions to slow down and even reverse global warming has been posited as humankind’s greatest challenge. It is a goal that is subject to considerable political and societal hurdles, but it also remains a technological challenge.

The news sounds almost too good to be true.

The Chinese megacity of Shenzhen has successfully switched 100 percent of its 16,359-vehicle bus fleet to electric vehicles, reaching its goal just six years after it vowed to move away from diesel engines, according to reporting by CleanTechnica and other news outlets. The fleet — which has three times as many buses as New York City — serves a population of 12 million. The switch is expected to save the equivalent of 345,000 tons of diesel fuel and cut 1.35 million tons of carbon dioxide emissions.

A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions from global fires. The new study resolves what looked like irreconcilable differences in explanations for the increase.

In 1870, explorer Adolf Erik Nordenskiöld, trekking across the barren and remote ice cap of Greenland, saw something most people wouldn’t expect in such an empty, inhospitable landscape: haze.

Engineers at The Ohio State University are developing technologies that have the potential to economically convert fossil fuels and biomass into useful products including electricity without emitting carbon dioxide to the atmosphere.

Cookstoves are a central part of millions of homes throughout Asia: families often use readily available and cheap biofuels — such as crop chaff or dung — to prepare the food needed to survive.

Short-term exposures to fine particulate air pollution and ozone—even at levels well below current national safety standards—were linked to higher risk of premature death among the elderly in the U.S. according to a new study from Harvard T.H. Chan School of Public Health.

The risk was even higher among elderly who were low-income, female, or Black.

The study was published December 26, 2017 in the Journal of the American Medical Association (JAMA).

Cities plagued with terrible traffic problems may be overlooking a simple, low-cost solution: High-occupancy vehicle (HOV) policies that encourage carpooling can reduce traffic drastically, according to a new study co-authored by MIT economists.

Charcoal remains after a forest fire help decompose fine roots in the soil, potentially accelerating CO2 emissions in boreal forests.
