New research from the University of Minnesota, published in Proceedings of the National Academy of Sciences,  shows nitrous oxide emissions, a greenhouse gas, may get worse as the climate warms.

China is rapidly expanding its solar power supply, hoping to meet 10 percent of the nation’s electricity needs with solar energy by 2030. But there’s a problem: Severe air pollution is blocking light from the sun, significantly reducing China’s output of solar energy, particularly in the northern and eastern parts of the country.

Despite widespread concern about potential human health impacts from hydraulic fracturing, the lifetime toxic chemical releases associated with coal-generated electricity are 10 to 100 times greater than those from electricity generated with natural gas obtained via fracking, according to a new University of Michigan study.

On New Year’s Day, 1909, a grocer named Julius Fried and his novice drilling crew, the Lakeview Oil Company, spudded a well in the desert valley scrub in the Midway-Sunset oil field, 110 miles north of Los Angeles. For the first 1,655 feet, the well yielded only dust, and then Lakeview ran out of money.

In 1995, the Governing Council of the United Nations Environment Program called for a united, global effort to reduce persistent organic pollutants (POPs) — synthetic chemicals such as PCBs, DDT, and dioxins. The compounds were known to persist and accumulate far from their sources, polluting the environment and causing adverse health effects in humans.

The annual assessment of global greenhouse gas (GHG) emissions by the JRC and the Netherlands Environmental Assessment Agency (PBL) confirms that CO2 emissions have stalled for the third year in a row.

Dispersal of mercury into the air has risen substantially since the industrial revolution, leading to increased mercury deposits in water and soil. Once there, it gets transformed by bacteria into methylmercury, a highly toxic form of the naturally-occurring heavy metal that can affect neurological and immune systems. Stored in the tissues of wildlife and humans, methylmercury concentrations are magnified with each step up the food chain. The mercury levels of a large predator fish such as trout, for example, may be more than one million times that of ambient water, potentially causing serious health consequences for human and wildlife consumers.

Pollution is linked to an estimated nine million deaths each year worldwide – equivalent to one in six (16%) of all deaths, according to a major new report in The Lancet. Most of these deaths are due to non-communicable diseases caused by pollution such as heart disease, stroke, lung cancer and chronic obstructive pulmonary disease (COPD).

Thirty years after NASA and NOAA launched a groundbreaking airborne campaign to study the Antarctic ozone hole, the two federal science agencies have once again joined forces over the world’s highest, driest and coldest continent to sniff out the secrets of the atmosphere.

On Oct. 14, NASA’s heavily instrumented DC-8 flew over Antarctica as part of the Atmospheric Tomography Mission or ATom, an unprecedented effort to sample the remote atmosphere to understand the distribution of man-made pollutants and short-lived greenhouse gases.

The JRC’s annual forest fires report confirms a trend towards longer and more intense fire seasons in Europe and neighbouring regions, with wildfires now occurring throughout the year. The report coincides with an international study which finds that global wildfire trends could have significant health implications due to rising harmful emissions.
