Earth's 'carbon dioxide breathing' seen from space
04 September 2013
Ten years of satellite observations of greenhouse gases reveal that carbon dioxide in our atmosphere continues to increase despite international efforts to reduce carbon emissions. Satellites also show that recent methane increases are likely due to manmade emissions.
Atmospheric carbon dioxide and methane are the two most important manmade greenhouse gases responsible for global warming.
Measurements from ESA's Envisat mission and Japan's Greenhouse gases Observing Satellite, GOSAT, show that carbon dioxide increased by about 0.5% every year between 2003 and 2013. After years of stability, methane began increasing by 0.3-0.5% per year from 2007 on.
