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…

Coal, which is by far the dirtiest fossil fuel, generates half of the electricity in the United States and 82% of the carbon dioxide emissions created by power production. Since it is abundant and cheap, it is likely to continue to play a major role in electricity generation for the foreseeable future. In the rhetoric of its champions, The United States is the Saudi Arabia of coal. Despite the introduction of
wind,
solar and other clean technologies, the
Department of Energy in its Annual Energy Outlook 2008 projects a small, 0.03% annual increase, in coal utilization through 2015. Surprisingly, maybe shockingly, they expect that growth rate to accelerate to 1% from 2015 to 2030 unless there are restrictions on carbon dioxide emissions or new clean technology…
