Up there, 10 to 50 kilometers above the Earth’s surface, ozone molecules absorb the sun’s ultraviolet light, protecting life far below. Even less is understood about the potential risks to people and the environment—could the particles deplete the ozone layer, for example, or significantly alter the weather? about 0.6 °C.

Scientists say much of the black carbon in the Arctic comes from biomass and fossil fuel burning in North America and Eurasia. A continuing decline in summer sea ice, warmer temperatures, changes in vegetation, and other indicators signal polar changes that affect the rest of the globe. Black carbon is contributing to this warming.

Other ancillary studies were led by Dr. Jeffrey Bemis, of Litron Laboratories, Rochester, New York; Dr. Lance Hallberg, of the University of Texas Medical Branch, Galveston, Texas; and Dr. Daniel Conklin, of the University of Louisville, Louisville, Kentucky. These ancillary studies evaluated endpoints not examined in the core study.

Brazil, the largest and most populous country in South America, was importing 80% of its oil and 40% of its foreign exchange was used to pay for that imported oil. The oil price shocks of the 1970s led the Brazilian government to address the strain high prices were placing on its fragile economy. This moonshine was hydrous ethanol.

The Bakken Formation, a shale oil and gas field in North Dakota and Montana, is emitting roughly 2% (about 250,000 tons per year) of the globe’s ethane, according to new study led by researchers at the University of Michigan. They directly impact air quality across North America. Ground-level ozone leads to poor air quality.

On the sixth anniversary of its first EV fast-charger installation, last week—the same week that Tesla laid off its Supercharger team— Electrify America confirmed big expansion plans. While recent EPA emissions rules for passenger cars and commercial trucks will help clean up particle pollution, ozone pollution remains a challenge.
