Title: Earth's Atmosphere Hasn't Had This Much CO2 in Millions of Years

Earth's atmosphere now has more carbon dioxide in it than it has in millions -
- and possibly tens of millions -- of years, according to data released last
month by the National Oceanic and Atmospheric Administration and scientists
at the University of California San Diego. From a report: For the first time,
global average concentrations of carbon dioxide, a greenhouse gas emitted as
a byproduct of burning fossil fuels, exceeded 430 parts per million (ppm) in
May. The new readings were a record high and represented an increase of more
than 3 ppm over last year. The measurements indicate that countries are not
doing enough to limit greenhouse gas emissions and reverse the steady buildup
of C02, which climate scientists point to as the main culprit for global
warming. "Another year, another record," Ralph Keeling, a professor of
climate sciences, marine chemistry and geochemistry at UC San Diego's Scripps
Institution of Oceanography, said in a statement. "It's sad."
