The U.S. Supreme Court recently rebuffed environmentalists in their bid to get the judiciary to intervene in the global-warming controversy by invoking the old common law of nuisance, as though global warming could be solved through an injunction.

Research suggests that institutions limit the extent to which efficient policies to reduce greenhouse gas emissions are likely to be adopted.

Policies to promote biofuels are extensive. The political rhetoric justifying them typically takes one of three forms. The first is to support farmer wealth.  The second is to reduce our dependence on foreign oil. And the third is to reduce greenhouse gases (GHGs).

The United Nations conference in Copenhagen will follow in the hypocritical footsteps of Kyoto, with countries declaring their resolution to curb GHG emissions while at the same time either refusing to pay the costs or claiming exemption from controls.

A critical step in reducing greenhouse gas emissions is the introduction of new technologies for energy supply and use.

The Boxer-Kerry Cap and Trade Bill is a "tougher" bill than Waxman-Markey, requiring a greater reduction of GHG by 2020 -- meaning requiring the impossible.

The Plundered Planet, by economist Paul Collier, offers a host of bold ideas regarding development economics and the environment, but ultimately fails to offer a convincing solution to climate change, as under current conditions, no such solution exists.

Based on Energy InformationAdministration estimates, it appears that the main thing Americans will gain from greenhouse gas reductions is higher energy bills.
