Study: CO2 in Atmosphere to Remain Above Threshold of 400 PPM
-------------------------------------------------------------

In another climate milestone, a study projects levels of carbon dioxide
in the atmosphere will smash the threshold of 400 parts per million this
year and not fall below it again in our lifetimes. The
400-parts-per-million threshold has been an important marker in U.N.
climate negotiations, widely recognized as a dangerous level that could
drastically worsen global warming. The environmentalist group 350.org
takes its name after the 350-parts-per-million threshold that scientists
say is the maximum atmospheric concentration of carbon dioxide for a
safe planet.
