Although there are many factors that influence the climate, one of the most significant is the greenhouse effect. The greenhouse effect refers to the warming that occurs as a result of greenhouse gasses (GHG) trapping energy in the atmosphere. An underlying principal of the greenhouse effect is that all objects radiate heart to some degree. Now with that in mind, check this out, so the sun is our primary heat source and it radiates energy (i.e. heat) which passes through the Earth’s atmosphere and warms the earth’s surface. As the surface of the earth warms up it also emits energy in the form of radiation ie heat. If greenhouse gases did not exist in our atmosphere, all of that energy would be emitted back into space and temperatures on Earth would plummet well below freezing. However, our planet maintains reasonably balanced temperatures thanks to the presence of greenhouse gases. These gases trap some of the energy that radiates from the earth’s surface so that it can warm our atmosphere. So you see we need a greenhouse effect; without it earth would be uninhabitable…. However, any fluctuation in the concentrations of these gases would either warm or cool the planet . So, what we are experiencing now is that the concentration of greenhouses gases has increased and so more heat is being trapped and ultimately temperatures are increasing. Greenhouse gases, including CO2, H2O, nitrous oxide, methane and ozone, are generated by a number of natural and man-made processes. Energy production and deforestation are some of the most notable anthropogenic sources of greenhouses gases. In nature they are generated through the carbon cycles in which humans, animals and a number of microorganisms produce these gases. From this very basic knowledge we can simply conclude that greenhouse gases are emitted by a large number of entities and our mission is to work on reducing these emissions as much as possible beacuse althought they occur naturally a greater percentage of greenhouse gases is generated by human factors. Here is where you can play a crucial role! For instances, energy production results in production of GHGs, one simple measure you can take is to reduce your energy consumption so instead of facebooking, talking on the phone, watching TV and blow-drying your hair all at the sametime(I do not know how this possible) take easy and cut down on electricity usage while giving your brain a little break from all that at the same time. JUST a thought!
