Evidence of global warming
Global Warming is the most talked about topic, and the evidence of global warming are all over the world recently. The phenomenal increase in the Earth’s temperature due to the greenhouse gases like carbon dioxide (CO2), methane, nitrous oxide etc is the main reason for global warming. The greenhouse effect is the most important cause for global warming. It is very important to have these greenhouse gases, but at permissible levels, as these gases trap the heat rays from the Sun and provide the much needed thermal blanket for the Earth which is ideal for us human beings, animals and plants to survive in this world.
But, in the last couple of decades, there has been an alarming increase in the emission of CO2 in the atmosphere that has made the Earth warmer than usual and hence we find an increase in the temperature. So, we see more and more temperature being absorbed in the atmosphere, which increases the temperature of the Earth gradually causing global warming. But, more then presence of CO2 in the atmosphere, the more will be the effects of global warming on Earth. The causes of global warming are many like emission of greenhouse gases into the atmosphere from man made factories, industries, vehicles etc; deforestation of natural vegetation and forests; Chlorofluorocarbons (CFC) used as jet propellant and in aerosol sprays and refrigerators; emission of methane gases from marshy places etc.
