This page presents background of the global warming issue, not a solution. The original measurements taken by C. D. Keeling at Mauna Loa on the ‘Big Island’ of Hawaii since the 1950s are still being added to by NOAA (the National Oceanic and Aeronautic Administration). It was these measurements that provided the incontrovertible evidence that CO2 levels worldwide were increasing in a very real, measurable, and disturbing manner.
CO2 is the principal ‘greenhouse gas’ with which we must be concerned due to its prevalance over all others. Methane, another greenhouse gas, is far more potent in its heat trapping properties. But methane degrades to CO2 rather rapidly (in a matter of weeks or months) when released into the atmosphere. The principal sources of methane are the livestock industry and the thawing of the Siberian permafrost at present.
Here is a link to the NOAA website for the Earth System Research Laboratory - Global Monitoring Division, that monitors the Trends in Atmospheric Carbon Dioxide. Take a look at this original data. The most recent 4 year period is displayed, but a link part way down the page takes you to the entire record of data in graphic form.
