How much confidence do we have in the science?
Researchers use the scientific method to search for cause and effect relationships. This method requires that a
hypothesis be constructed. Scientists then design an appropriate well-controlled experiment to test that hypothesis. The results must be statistically significant and reproducible in order to be considered valid. There are a number of techniques that can be used to enhance the objectivity of a study as well as increase its statistical reliability.
In prospective medical research for example, we often use double blind, placebo controlled studies so that neither the researcher nor the patient knows if they are receiving the active drug or a placebo. This eliminates observer bias. Some times we cross the patient's over, so that the same patient takes both the active…

When the only tool you have is a hammer, the whole world looks like a nail. In other words, there is no problem that a bureaucrat can't solve, if only we would let them pass another regressive tax. That may well be the sum total of the creative thinking that has gone into the Obama
Cap-and-Trade plan. The Obama Administration proposes that companies buy a permit for each ton of carbon emitted, at an estimated cost, to start of $13 to $20 per ton. The permits could then be bought and sold. The theory behind this convoluted scheme is that it will somehow miraculously increase energy efficiency and renewable energy development.
Rather than focus on available technological solutions, let's burden hard working American consumers with another ill-conceived regressive tax! Who…

Only one industrial country in the world has significantly reduced its carbon footprint, and that country is France. France, the sixth largest economy in the world, ranks 15th in
carbon dioxide emissions, behind pre-industrial economies like Iran and Indonesia. France has simultaneously, reduced its dependence on foreign sources of fossil fuels, coal, natural gas and oil. While we dither with small-scale experimental intermittent technologies like
solar and
wind in the United States, France has gone nuclear and clean. In 2008
wind and solar accounted for 1.1% of US energy needs and even if we meet President Obama's objective of doubling the amount by 2012, its contribution will still be inconsequential. In the best-case scenario for wind and solar, they might together generate 20%-25% of our clean…

Heat from the Earth, or
geothermal - Geo (Earth) + thermal (heat) - energy can be readily accessed by drilling water or steam wells in a process similar to drilling for oil. Domestic geothermal energy is an enormous, and underused heat and power resource that emits little or no greenhouse gases. Mile-or-more-deep wells can be drilled into underground reservoirs to tap steam and very hot water that can be brought to the surface for use in a variety of applications. In the U.S most geothermal reservoirs are located in the western states, Alaska, and Hawaii. About 8,000 megawatts of electricity are currently produced globally including about 3,000 megawatts of capacity in the United States. The
US Department of Energy believes that an additional 15,000 megawatts of geothermal electricity…
