Description

CO2 reports the concentration of carbon dioxide in the atmosphere, as measured by the U.S. NOAA's Manua Loa Observatory ( http://www.esrl.noaa.gov/gmd/ccgg/trends/weekly.html ). The main value is the previous week's average, and it is compared to the weekly average taken 1 year ago and 10 years ago. This watchface uses the API developed by HQCasanova ( http://www.hqcasanova.com/en/projects/co2.php ).
