With Al Gore's An Inconvenient Truth released on video last weekend, and with the Supreme Court intending to hear its first case on global warming starting today, human-induced climate change is clearly a hot topic.
In a case led by Massachusetts and supported by the Environmental Protection Agency, 11 other states (including Washington) and various environmental nonprofits, the Bush administration's stance on the regulation of carbon dioxide emissions will be challenged in the high court.
The EPA is seeking clarification of its authority to regulate carbon dioxide as a pollutant, just as it would regulate other harmful chemicals. If carbon dioxide were considered a pollutant, the EPA would likely be given authority to crack down on CO2 emissions.
Carbon dioxide is considered to be a main contributor to global warming, because it is being filtered into the atmosphere at an "unprecedented rate," according to a recent Associated Press article.
