Help, The House Is Burning Down

We Maybe In More Trouble Than We Thought! 

U.N.: 2006 set record

 for green house gases



GENEVA—Two of the most im­portant greenhouse gases in the Earth’s atmosphere reached a record high in 2006, and measure­ments show that one — carbon dioxide — is playing an increasing­ly important role in global warm­ing, the U.N. weather agency said Friday.

The global average concentra­tions of carbon dioxide, or CO2, and nitrous oxide, or N2O, in the atmosphere were higher than ever in measurements coordinated by the World Meteorological Organi­zation, said Geir Braathen, a cli­mate specialist at the Geneva-based agency.

Methane, the third of the three important greenhouse gases, remained stable between 2005 and 2006, he said.

Braathen said measurements show that C02 is contributing more to global warming than previ­ously. CO2 contributed 87 percent to the warming effect over the last decade, but in the last five years alone, its contribution was 91 per­cent, Braathen said. “This shows that C02 is gaining importance as a greenhouse gas,” Braathen said.

 The concentration of carbon dioxide in the.atmosphere rose by about, which is a quarter percent higher than in 2005. Braathen said it appears the up­ward trend will continue at least for a few years half a percent last year to reach 381.2 parts per million, ac­cording to the agency. Nitrous oxide totaled 320.1 parts per bil­lion

The World Meteorological Orga­nization’s annual Greenhouse Gas Bulletin provides widely accepted worldwide data on the amount of heat-trapping greenhouse gases in the atmosphere.

Studies have shown that human-produced carbon dioxide emissions heat the Earth’s surface and cause greater water evaporation. That leads to more water vapor in the air, which contributes to higher air temperatures. C02, methane and N20 are the most common green­house gases after water vapor, ac­cording to the meteorological or­ganization.

They are produced by natural sources, such as wetlands, and by human activities such as fertilizer use or fuel combustion. There is 36.1 percent more car­bon dioxide in the atmosphere than there was in the late 18th century, primarily because of combustion of fossil fuels, the World Meteorolog­ical Organization bulletin said.A report presented by a U.N. ex­pert panel said last week that aver­age temperatures have risen 1.3 de­grees Fahrenheit in the last 100 years, and that 11 of the last 12 years have been among the warmest since 1850. Global Warm­ing also led to a sea level increase by an average seven-hundredths of an inch per year since 1961, ac­cording to the U.N. Intergovern­mental Panel on Climate Change.The panel’s report, which said human activity is largely responsi­ble for global warming, noted that the concentration of carbon dioxide in the atmosphere is far higher than the natural range over the last 650,000 years.
