    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…
