2005 recordjaar voor broeikasgassen

"Greenhouse gases in the Earth's atmosphere reached a high in 2005 and are still increasing, the U.N. weather agency said Friday. The measurements coordinated by the World Meteorological Organization show that the global average concentrations of carbon dioxide, or CO2, and nitrous oxide, or N2O, reached record levels last year and are expected to increase even further this year, said Geir Braathen, a climate specialist at the Geneva-based agency.

The concentration of carbon dioxide rose by about half a percent last year to reach 379.1 parts per million, according to the agency. Nitrous oxide totaled 319.2 parts per billion, which is 0.19 percent higher than in 2004. Levels of methane, another so-called greenhouse gas, remained stable since last year, Braathen said."
