The Intergovernmental Panel on Climate Change reports that CO2 emitted by jets can survive in the atmosphere for upwards of 100 years, and that its combination with other gas and particulate emissions could have double or four times the warming effect as CO2 emissions alone.
Dear EarthTalk: I was appalled by the pollution haze I saw on a recent visit to Acadia National Park in Maine, and was told by a ranger that it was from smokestacks and tailpipes hundreds of miles away. Is anything being done to clear the air in Acadia and other natural areas where people go to breathe fresh air and enjoy distant unobstructed views?-- Betty Estason, via e-mail
June is National Rivers Month, which means it’s a good time to talk about a recent film chronicling the effort to clean up the Nashua River. It’s called “Marion Stoddart: The Work of 1000” and has been screened at a number of environmental film festivals.
Susan Edwards is the film’s producer, and she talks with All Things Considered host Brady Carlson about, the film, Marion Stoddard and the Nashua River.
Oil field workers drill into the Gypsum Hills near Medicine Lodge, Kan., on Feb. 21. The Environmental Protection Agency announced new rules Wednesday to control the problem of air pollution coming from wells being drilled by the booming oil and natural gas drilling industry.
The Environmental Protection Agency's new air pollution rules for the oil and gas industry may seem like odd timing, as President Obama has been trying to deflect Republican criticism that he overregulates energy industries. But the rules weren't the Obama administration's idea.
Several years ago, communities in Colorado, New Mexico and Wyoming complained about air pollution from natural gas booms in their local areas.
The Environmental Protection Agency announced new rules Wednesday to control the problem of air pollution coming from wells being drilled by the booming oil and natural gas drilling industry.
Currently, waste products from the drilling operations, which include a mix of chemicals, sand and water, can be pumped into open enclosures or pits, where toxic substances can make their way into the air. The new rules will require this fluid to be captured by 2015, and flared — or burned off — in the meantime.
The man who warned us that aerosol spray-cans could destroy the earth's protective ozone layer has died.
F. Sherwood Rowland, better known as Sherry Rowland, was a Nobel-prize winning chemist at the University of California, Irvine. And he didn't just keep to the laboratory: He successfully advocated for a ban on ozone-destroying chemicals called CFCs.
Dear EarthTalk: I was in Los Angeles recently and the smog was not nearly as bad as when I visited 15 years ago. Is it really better now, and if so, how did it get that way? Or did I just happen to visit on a good day?-- Marjorie Hicke, Atlanta, GA
Dear EarthTalk: I was horrified to read recently that our oceans are actually becoming acidic, that the continued burning of fossil fuels is changing the chemistry of our seas. What’s going on? -- Kim Richardson, San Diego, CA
A truck passes shipping containers at China Shipping at the Ports of Long Beach and Los Angeles, the busiest port complex in the U.S., near Long Beach, Calif. Stricter emissions standards have cut down on air pollution from the trucks, which has been one of the most significant sources of air pollution in California for many years.

Trucks at the Ports of Los Angeles and Long Beach often idle while they wait to be loaded and unloaded, adding to the pollution.
Ten Northeastern and Mid-Atlantic states have, in the face of federal inaction, agreed on a region-wide greenhouse gas emissions limit, enforced through the sale of pollution permits to large fossil fuel power plants there.
