The National Oceanic and Atmospheric Administration measures the direct climate influence of many greenhouse gasses through the Annual Greenhouse Gas Index, also known as the AGGI, and it showed that a rise in greenhouse gasses between 2009 and 2010. Started in 2004 the AGGI does not provide exact details as to what the temperature increases [...]Show More Summary
NOAA's updated Annual Greenhouse Gas Index (AGGI), which measures the direct climate influence of many greenhouse gases such as carbon dioxide and methane, shows a continued steady upward trend that began with the Industrial Revolution of the 1880s.
Two of the most important climate change gases increased last year, according to a preliminary analysis for NOAA's annual greenhouse gas index, which tracks data from 60 sites around the world....
