CO2 AND CLIMATE CHANGE

The most well-known and the most important greenhouse gas is CO2. The concentration of CO2 in the atmosphere is subject to variation even without human intervention. The carbon cycle causes an exchange of CO2 between the biosphere and the oceans on the one hand and the atmosphere on the other.
Vast amounts of CO2 are also released by the burning of fossil fuels. there is incontrovertible evidence that the CO2 concentration in the air has never been so high in 8,00,000 years(probably even 60 million years) as it is now.
The trend suggests that CO2 emissions will continue to rise globally, although the economic crisis did prevent a rise in 2009. 
Besides CO2, methane (CH4), nitrous oxide (N2o), fluorinated gases, ozone (O3) and water vapour are important greenhouse gases. Water vapour plays a unique role as it strengthens the heat-trapping effect caused by other greenhouse gas emissions.
This is because a warmer atmosphere retains more water. The amount of water vapour cannot be artificially increased or decreased.

Impact of Global Warming on Animals

Impact of Global Warming on Animals Loss of Habitat As global warming causes climate change, many great deserts like the Sahara, are no longer able to sustain their animal population. Loss of habitat is most vividly seen in the Arctic, where global warming is melting the glaciers, pushing the polar bears into extinction, The melting glaciers have caused water levels to rise in many oceans, threatening to drown many tropical islands and forests, that teem with animal life. Loss of Food Grasslands are also adversely affected by global warming. The effects include high rate of evaporation, higher temperatures, frequent and severe droughts, reduced rainfall, and lower nitrogen content in forage grasses. Lower nitrogen concentration in the vegetation causes improper digestion in animals resulting in reduced strength, performance and health of animals. To make room for an ever-growing population, many forests, grasslands, and even desserts, have been made habitable fo...

CAUSE - Aerosols

CAUSES OF CLIMATE CHANGE Aerosols Aerosols are less well-known than greenhouse gases. Aerosols are dust particles which, in addition to CO2, are released into the atmosphere in large quantities when wood and fossil fuels are burned. Some aerosols have a cooling effect on the climate, others have a warming effect. On balance they have a cooling rather than a warming effect, but no-one can give a clear idea of the magnitude, because we still do not understand how aerosols influence the occurrence and characteristics of clouds. Natural phenomena, greenhouse gases and aerosols create an imbalance in the incoming and outgoing radiation in the atmosphere. This process is known as Radiative forcing. When the earth heats-up, the short-wave radiation from the sun that enters the atmosphere is greater than the long-waves radiation that exists the atmosphere. The temperature changes on Earth will not stop until the radiation balance is restored. Given the immense capacity of ocean...
