Global Greenhouse Pollution Surge Continues | The United Nations World Meteorological Organization (WMO) reports that greenhouse pollution continues to build in the global atmosphere at a terrifying rate. Carbon dioxide, methane, and nitrous oxide “reached new highs in 2010,” “greater than those in pre-industrial times (before 1750) by 39%, 158% and 20%, respectively.” From 1990 to 2010, radiative forcing by long-lived greenhouse gases increased by 29 percent. That is to say, since the global convention in Rio de Janeiro in 1992 at which the nations of the world pledged to prevent dangerous global warming, the intensity of global warming has increased by nearly a third. Most of the increase in pollution has come from the burning of fossil fuels, reaping untold profits for oil and coal magnates at the expense of civilization’s future. More than a quarter of all of the carbon pollution produced by the United States has come since then.
