carbon‚ and halocarbon. These gases absorb the heat radiated from Earth’s surface and lower atmosphere while radiating most of the energy back toward the surface. The humane activities such as transportation‚ mining‚ agriculture‚ fossil fuel burning‚ and many others have increased the concentration of these gases. The result is a thick blanket in the atmosphere of these “heat trapping gases in Earth’s atmosphere‚ causing surface temperature to rise.” http://www.globalchange.gov/publications/repor

What impact might CO2 emissions have on overall global warming? In the 19th century‚ scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet’s temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century‚ Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed

Since the beginning of the early 20th century‚ the earths mean surface temperature had increased by around 0.8 degrees. Warming of the climate system had become more obvious and scientists are 90% sure that the main cause of the increase in temperature in due to the increasing concentrations of greenhouse gases due to human

releasing more and more greenhouse gases into the atmosphere for a variety of reasons. We are doing this by burning fossil fuels. When fossil fuels are burned‚ they release harmful greenhouse gases into the atmosphere. These greenhouse gases then remain in the atmosphere‚ and trap most of the heat from the Sun‚ causing the global temperatures to increase. There are three main reasons for why humans are beginning to put more greenhouse gases into the atmosphere. The main thing we use fossil fuels is to

the planet. It reaches a surface temperature of 900° F. This is hotter than Mercury‚ which is closer to the sun. This temperature is hot enough to melt lead. This higher temperature is attributed to a runaway greenhouse effect caused by the heavy atmosphere of carbon dioxide. This would also probably account for the lack of water on the planet. The oceans‚ if there were ever any‚ were probably boiled away millions of years ago. The extremely hot temperature also attributes to the fact that no life

I think that acid rain is not really safety because it might give us trouble breathing. Some carbon dioxide is normal in the atmosphere‚ ant it helps creating clean atmosphere‚ preventing Earth from being frozen. Acid rain also makes the oceans more acidic. Acid rain is bad and good at the same time‚ so depend on

gases that are given off in large quantities by factories and power stations as well as motor vehicles enhance the greenhouse effect‚ which has a negative impact on global warming. Carbon dioxide‚ during the burning process‚ creates a layer in the atmosphere which stops the heat from escaping into the space. When the heat can’t escape it comes back to the earth and causes warming that leads to melting of ice caps and as result of it the sea level may raise and some part of the land such as Japan or
