On June 26, a 1,427-page climate change bill introduced by Representatives Henry Waxman (D-CA) and Edward Markey (D-MA) passed the House by a narrow margin. The bill, also known as Waxman-Markey, includes a number of alarming provisions, chief among them a cap-and-trade program that would attempt to curb global warming by imposing strict upper limits on the emission of six greenhouse gases, with the primary emphasis on carbon dioxide (CO2).
