Note that in this hot, never-ebbing, electoral season, global warming is not among the issues given much attention. This is the case despite the fact that the trend in rising temperatures and the concentration of greenhouse gases in the atmosphere continue to rise at crisis levels, and that 97% of all climate scientists have been persuaded by the best scientific evidence that global warming is having increasingly deleterious and disruptive effects on the climate. Recent polls find that an increasing percentage of respondents agree that global warming is occurring, that it is caused by human activities, most notably by the burning of fossil fuels for energy, and that the government should take actions that would reduce the problem.
If we lived in a more politically responsive time, government would pass and enforce a carbon tax and undertake massive support for renewable energy, conservation, and efficiency policies. As the matter stands, the Republicans in the U.S. Congress oppose and would surely stop any such legislative initiatives and the Democrats with other priorities have not pressed the issue.
