Cause and Effect of Global Warming

Transportation and Global Warming

Global warming is a that has been subject to much debate . Many fear its possible catastrophic effects but many still say that global warming is a hoax and people do not need to fear it . To better understand the real predicament , it is important to know what causes global warming as well as what devastating effects it poses . Global warming is caused by many factors but one of the major contributors to global warming is the increasing number of vehicles on the streets

Global warming is also referred

to as climate change or the greenhouse effect . Generally , it is caused by the substantial increase in the amount of greenhouse gases in the atmosphere such as water vapor , carbon dioxide , ozone and methane . These greenhouse gases were initially not harmful but as the greenhouse gases rise to uncontrollable levels , more heat is being trapped inside the earth 's atmosphere which results in significant increases in temperature . Scientists indicate that the greenhouse effect is important to the earth 's ecosystem as without it the planet would be too cold to sustain the natural ecosystems that are thriving today (West

Climate change is now a very controversial that the media has been putting a lot of attention into it . Newss and magazines now usually feature stories on global warming . Time Magazine often has cover stories relating to climate change . Politicians have also become aware of the subject such as former US Vice President Al Gore who has become a staunch advocate of anti-global warming campaigns

Climate change is caused by a variety of factors but main contributors to global warming may be blamed on human acts , particularly because of increasing vehicle emissions . As population rises , the demand for vehicles also rises . All modes of transportation contribute to global warming . Vehicles produce greenhouse gases . Subway trains may appear harmless because it does not directly produce harmful exhaust but electricity is used to power these trains and many countries use coal to produce electricity and this also causes more greenhouse gas emissions Even modes of transportation powered by electricity contributes to global warming

A quarter of the carbon dioxide emissions in the US may be traced from motor vehicles . Carbon dioxide is the main greenhouse gas responsible for climate change and it mostly comes from vehicle emissions (Clean Vehicles . Moreover , based on data provided by the Intergovernmental Panel on Climate Change , airplanes contribute to 3 .5 percent of greenhouse gases responsible for global warming (Causes of Global Warming

Fossil fuels are used to produce energy and this is not good because fossil fuels produce a lot of emissions . Vehicles mainly consume large amounts of fossil fuel and the vehicle industry is what keeps the oil industry pumping . Electric cars however do exist and these were actually used before but it was overtaken by gasoline-powered cars which increased in production . These electric cars are now being revived and California is leading the campaign as the California Air Resources Board prompted...
