ग्रीनहाउस गैस उत्पादन पर मानवकृत गतिविधियों और कृषि कार्यो का प्रभाव Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gas­es, aerosols (small particles), and cloudiness. Human activities like burning of fossil fuels (coal, oil and natural gas), deforestation and various agricultural and industrial practices, are altering the composition of the atmosphere and contributing to climate change.  These human activities have led to increased atmospheric concentrations of a number of greenhouse gases (GHGs), including carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and ozone in the lower part of the atmosphere. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to...

कार्बन ट्रेडिंग पर अंतर्राष्ट्रीय सम्मेलन और वैश्विक पहल Carbon is the common denominator in all polluting gases that cause global warming. Carbon dioxide is the gas most commonly thought of as a greenhouse gas. It is responsible for about half of the atmospheric heat retained by trace gasses. It is produced primarily by burning of fossils fuels and deforestation accompanied by burning and bio-degradation of biomass.  It is estimated that if the CO2 increases in the atmosphere at the present rate and no positive efforts are pursued, the level of CO2 in the atmosphere would go up to 800-1000 ppm by the end of current century. Which may create havoc for all living...
