Fossil Fuels & Global Warming: How are they Related?

Coal, oil and natural gas are the three different forms of fossil fuels that are widely used. They are formed by the process of anaerobic decomposition of organic matter under the surface of the earth for millions of years. Large-scale use of fossil fuels started since the Industrial Revolution. Today, these are the most widely used sources of energy available for the use of both personal as well as commercial purposes. Petroleum is used to fuel our vehicles, while coat and natural gas are used to produce electricity for our homes and offices. Almost three-fourth of the demands of the energy in the world is fulfilled by fossil fuels.

Higher Seas

Rise in sea level can adversely affect the climate of the earth. It is believed that there will be drastic changes in the weather conditions in various parts of the world. The glaciers of the earth will melt at a much faster pace. As a result, the areas which are located near the water bodies like, the coastal regions and the banks of the river, are likely to get submerged under water.

CAUSE - CO2 AND CLIMATE CHANGE

CAUSES OF CLIMATE CHANGE 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 beca...

Deforestation

Deforestation What is Deforestation? Deforestation is when humans remove or clear large areas of forest lands and related ecosystems for non-forest use. These clearing for farming purpose, ranching and urban use. In these cases, trees are never re-planted. It is any activity directed to forests resources, with the intention of using the trees or land created for other purposes. Trees may be cut down for logs or burned to make room for farms, construction or other economic purposes. Why do humans clear forest? High demand for wood More need for pulp and paper, wood for furniture, real estate construction fuel all mean that trees will be cut down. World population is growing and more than ever before, our needs have increased too. Animal grazing fields In many places in the world, animal farms have contributed to large areas as green space being converted to grazing fields. Classic cases can be found in Brazil. Animal rearing in the Amazon has increased remarkable o...

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...
