Global Climate Change

Should our democracy adopt a cap-and-trade system to limit greenhouse gas emissions?

A 2003 U.S. Department of Defense report warned how climate changes could lead to unrest—even war—because of food shortages, the loss of fresh water, interruptions of energy supplies, and the migration of millions of desperate people. UN Secretary General Ban Ki-Moon has said that global climate change poses a threat to humanity and the planet that is as grave as war (Osborne, 2007). Most nations now agree that something must be done soon to avert a catastrophe. Countries are particularly interested in reducing the harmful effects of greenhouse gases, particularly carbon dioxide (CO2). Cap-and-trade policies offer one way to do so.
