    What is the present level of atmospheric carbon dioxide ?

    What is the present level of atmospheric carbon dioxide? On May 9th, 2013, the global atmospheric daily concentration of CO2 crossed 400 ppm level mark.  On that day the recorded CO2 Concentration was 400.03 ppm as per the NASA’s Mauna Loa observatory in Hawaii. The observatory has been monitoring the atmospheric concentration since last 57 years. The crossing of 400 ppm mark made news. The scientists from National Oceanic and Atmospheric Administration (NOAA) and Scripps Institute of Oceanography both in USA confirmed these observations. The CO2 concentration in the atmosphere does not remain same throughout the year. In fact, it varies with the changing season. From springs till later part of…

    Minimum Carbon Dioxide Levels in the Atmosphere Crosses 400 ppm Mark

    Each year during the spring season the carbon dioxide levels in the atmosphere reaches to its minimum. The reason is that during this time the plants get new leaves and they grow maximum. The more the leaves sprout, the more the leaves grow, the more photosynthesis will take place which means enhanced intake of atmospheric CO2 to produce food. This reflects as a dip in the atmospheric concentration of CO2. During the harsh winters and fall the plants shed their leaves. It is this time that the global CO2 level reaches to its annual high. As per the NASA’s observations based on the Atmospheric Infrared Sounder (AIRS) instrument, the annual…
