This is both news and probably political but on the off chance that it is more science and news, I thought I would start it here.
There has been a number of non-political discussions on global warming here so thought I would add this. Of course Kyoto comes to mind, as I seem to recall, maybe incorrectly, that china and india were not bound at least initially under kyoto, so that makes some of this interesting. While the US output is lessening I know we have had some impact on others such as europe?
Just thought I would supply this nugget of info in the ongoing discussion about this important subject.

Of course it is a zero sum game, and the US contributes to the overall levels of all pollutants, but while some are decreasing others are increasing, that I think is the problem for now.

Pollution wafting into the USA accounts for 30% of the nation's ozone, an important component of smog, says researcher David Parrish of the National Oceanic and Atmospheric Administration. By the year 2020, Harvard University's Daniel Jacob says, imported pollution will be the primary factor degrading visibility in our national parks.
While the United States is cutting its own emissions, some nations, especially China, are belching out more and more dirty air. As a result, overseas pollution could partly cancel out improvements in U.S. air quality that have cost billions of dollars.
Among the efforts that could be undermined: the Environmental Protection Agency's new drive to cut power plants' emissions of ozone-forming chemicals and particle pollution, specks of chemicals that damage health. The EPA finalized the rule Thursday.
The EPA will announce limits Tuesday on mercury emitted by U.S. power plants. But the agency estimates that 40% of the mercury that sinks out of the air and lands in the USA comes from overseas.
"A number of things are getting here that we're worried about," says David Streets, an environmental scientist at Argonne National Laboratory in Chicago. "Some of these (pollutants) are not easy to control. ... I don't expect things to get better in the next 10 years or so, and some things will get worse."
Almost every place in the USA has suffered from the effects of imported air pollution, at least occasionally. Some of the most serious impacts:
Mercury emitted by power plants and factories in China, Korea and other parts of Asia wafts over to the USA and settles into the nation's lakes and streams, where it contributes to pollution that makes fish unsafe to eat.
Dust from Africa's Sahara Desert blows west across the Atlantic Ocean and helps raise particle levels above federal health standards in Miami and other Southern cities.
Haze and ozone from factories, power plants and fires in Asia and Mexico infiltrate wilderness spots such as California's Sequoia National Park and Texas' Big Bend National Park, clouding views and making the air less healthy
