Carbon dioxide and methane rise in 2007
The National Oceanic and Atmospheric Administration (NOAA), an U.S. agency, is working with
its partners, the European Union and more than 70 countries,
to develop a global environment monitoring network.
According to the 2007 experimental data, carbon dioxide in the atmosphere rose by 0,6% ( or 19 billion tons),
compared to previous year, boosting the global concentration to 385 ppm (parts per million). The 2007 rise in global carbon dioxide
was significantly higher than the average annual increase for the last 30 years.
Carbon dioxide is the main driver of the global climate change.
Methane level in the atmosphere rose in 2007 for the first time since 2008.
