Greenhouse Gases-Carbon Dioxide
{"Image DocumentName": "Greenhouse Gases-Carbon Dioxide", "Image ImageDescription": "Major sink for CO2; Photosynthetic uptake by plants. Atmosphere to ocean flux. These natural cycles maintained the atmospheric CO2 concentration at about 280 \u00b1 10 ppmv (parts per million by volume) for several thousands years prior to industrialization in the mid-nineteenth century. During the past 150 years, and especially during the last lew decades, humans greatly increased the concentration of atmospheric CO2.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
