Global Warming :: Greenhouse Gases Climate Change

For decades and decades, human factories and cars have discharged billions of hemorrhoid of artificial greenhouse gases into the atmosphere, and the climate has begun to show many signs of global melt. On the other hand, some people want you to believe that global warming does not exist. There are many people who are all out for personal gain and are outright liars. According to a scientist at NASA worldwide warming is the single largest threat to our planet(Weier 2002). everywhere the past two hundred years we have seen significant changes in the effects on our environment, primarily due to humans and both their wishing of awareness, or their amount disregard for the effects that their actions have on the environment.Global warming is one of our toughest environmental challenges. It threatens the health of people, wildlife and economies around the world. The problem is degree Celsius dioxide and other heat-trapping pollution. This pollution mainly comes from cars, power plant s and other industrial sources that sunburn gasoline, combust and other fossil fuels. This matter collects like a cover charge in our atmosphere. As a result, the planet gets warmer. We can say that the amount of light beam from the sun that reaches the earth each year has been fairly accordant from year to year and century to century until recently. Thirty percent of the total solar strength that strikes the earth is reflected back into blank space by clouds, atmospherical aerosols, reflective ground surfaces, and even ocean surf. Seventy percent of the solar energy is absorbed by the land, air and oceans. The absorbed light is broadly in the form ultraviolet and near infrared solar radiation(Weier 2002). Absorption of this solar energy makes life on this planet possible. The energy does not stay bound up forever. If it did our planet would wind up being hotter than the sun. Instead, when the rocks, air, and sea heat up, they give off thermal radiation, which escapes into s pace and allows it to cool down. This radiation is invisible to our eyes, but our hands can note it radiating from a fire or a car engine.What we should be worried about now is that over the past 250 years, we have been artificially raising the concentration of greenhouse gases in our atmosphere. Factories, power plants, and cars, burn coal and gasoline and spit out a seemingly endless rate of flow of carbon dioxide. Power plants are the largest contributors to global warming.
