The highest purity searches to date have made use of relatively clean signals such as the presence of emission or absorption features at two distinct redshifts in the same optical spectrum (e.g. Bolton et al. 2004), or the strong «magnification bias» towards detecting strongly lensed sources in the sub - mm / mm waveband (e.g. Negrello et al. 2010).

A narrow band of them in the high - energy spectrum would be a «smoking gun» for the presence of dark matter, says Michelson, but he thinks it's more likely that the dark matter emission would be mixed in with gamma rays from other energy sources in the universe and that scientists such as GLAST pioneer Elliott Bloom will have to work very hard to untangle the GLAST data to find it.

The current estimates show that cellular agriculture can have lower greenhouse gas emissions, land use and water use, but often has a higher energy use requirement when compared to conventionally produced animal source foods.

Also this would seem to indicate that the emission center of highest intensity is not direct back at the source but offset by about 25 % from the angle of incidence.

Higher density sources of fuel such as coal and natural gas utilized in centrally - produced power stations actually improve the environmental footprint of the poorest nations while at the same time lifting people from the scourge of poverty... Developing countries in Asia already burn more than twice the coal that North America does, and that discrepancy will continue to expand... So, downward adjustments to North American coal use will have virtually no effect on global CO2 emissions (or the climate), no matter how sensitive one thinks the climate system might be to the extra CO2 we are putting back into the atmosphere.

Further, increased human - caused CO2 emissions mean more energy use, which results in more human productivity since humans generally use fossil fuel energy to increase their productivity and reduce their dependency on other less reliable and higher cost energy sources.

In some of these countries there is little or no coal - powered generation at present; building coal plants is likely to prevent the development of other, less polluting energy sources and lock in high emission power structures for years to come.

«The CO2 numbers [in the oil sands] sound frightening when only the production and refining are taken into account...
