Scientists believe that carbon dioxide, the main emission from these plants, is a leading cause of recent global warming.
The United States remains the leading source of the carbon dioxide, the main emission linked to global warming.
At the time, the E.P.A., complying with a Supreme Court ruling, was finishing a document assessing whether carbon dioxide, the main emission linked to global warming, endangered public health or welfare as defined under the Clean Air Act.
At that site, she said, contamination has been somewhat harder to track because it is mostly plutonium, whose main emission is alpha particles that travel only a few inches in air, unlike the gamma rays from cesium and strontium at Hanford.
The response to the threat from CFC's — a treaty and phaseout that is working — has been held up as a model for what humanity can do with carbon dioxide, the main emission linked to warming and the biggest threat, because of its long lifetime in the air, to drive temperatures dangerously higher.
The main emission occurred from the 5D0 → 7 F2 transition.
Flaring is another main emission source of this greenhouse gas in petrochemical industry.
Table 1 shows the modes of several main emission trading markets.
Two main emission bands at 1.6 and 0.81 eV have been observed.
In this case, the integration window is too small to see the slow, main emission band.
Four main emission bands centered at 354, 423, 467, and 666 nm are observed.
