Global Warming Cause And Effect Essay

Global warming

Global warming refers to the increase in the temperature of earth’s surface due to the different causes.These causes may be the release of gases such as carbon dioxide and other harmful gases in the environment.This might be due to deforestation and the burning of feul in excess.The heat is trapped by the earth and it is not bounced back to the environment and hence it increases the temperature of the earth.

Is global warming caused by human activity,even remotely plausible or not?

Earth’s environment is mostly influenced by the first 6 miles.In these six miles all matter which influence the atmosphere are present.In the book the END OF NATURE author stated that layer present around the earth which protects it from the ultra

other second largest sources produces carbon dioxide 1.5 billion annually.Burning of fossil feuls,for electricity generation,transportation,heating and cement manufacturing all results in the emission of 22 billion tons of carbon dioxide in the environment.

One of the major cause of global warming is green house effect.The major contributor for this effect is co2.other gases also contribute e.g methane from the agricultural fields and nitrous from the fertilizers and gases from the industrial processes and loss of forests results in the accumulation of co2 in the atmosphere.Different green house gases have different capabilities to trap the co2.

For example a molecule of methane produces more heat than a molecule of co2.Other gases like chloroflorucarbons degrade the layer of ozone which have trapping potential thousands times of co2.But as their concentrations are lower hence they don’t cause much damage to the ozone layer as co2 does.since 1990 the annual emission has gone 6 billion metric tons worldwide which is the 20 percent
