Greenhouse Effect, the capacity of certain gases in the atmosphere to trap heat emitted from the Earth’s surface, thereby insulating and warming the Earth. Without the thermal blanketing of the natural greenhouse effect, the Earth’s climate would be about 33 Celsius degrees (about 59 Fahrenheit degrees) cooler—too cold for most living organisms to survive.\n\nThe greenhouse effect results from the interaction between sunlight and the layer of greenhouse gases in the Earth's atmosphere that extends up to 100 km (60 mi) above Earth's surface. Sunlight is composed of a range of radiant energies known as the solar spectrum, which includes visible light, infrared light, gamma rays, X rays, and ultraviolet light. When the Sun’s radiation reaches the Earth’s atmosphere, some 25 percent of the energy is reflected back into space by clouds and other atmospheric particles. About 20 percent is absorbed in the atmosphere. For instance, gas molecules in the uppermost layers of the atmosphere absorb the Sun’s gamma rays and X rays. The Sun’s ultraviolet radiation is absorbed by the ozone layer, located 19 to 48 km (12 to 30 mi) above the Earth’s surface.\n\nAerosols, also known as particulates, are airborne particles that absorb, scatter, and reflect radiation back into space. Clouds, windblown dust, and particles that can be traced to erupting volcanoes are examples of natural aerosols. Human activities, including the burning of fossil fuels and slash-and-burn farming techniques used to clear forestland, contribute additional aerosols to the atmosphere. Although aerosols are not considered a heat-trapping greenhouse gas, they do affect the transfer of heat energy radiated from the Earth to space. The effect of aerosols on climate change is still debated, but scientists believe that light-colored aerosols cool the Earth’s surface, while dark aerosols like soot actually warm the atmosphere. The increase in global temperature in the last century is lower than many scientists predicted when only taking into account increasing levels of carbon dioxide, methane, nitrous oxide, and fluorinated compounds. Some scientists believe that aerosol cooling may be the cause of this unexpectedly reduced warming. \n\nEffects:\n\nThe increase in global temperatures is expected to result in other climate changes including rises in sea level and changes in the amount and pattern of precipitation. Such changes may increase the frequency and intensity of extreme weather events such as floods, droughts, heat waves, and hurricanes, change agricultural yields, cause glacier retreat, reduced summer streamflows, or contribute to biological extinctions. Although warming is expected to affect the number and magnitude of these events, it is difficult to connect any particular event to global warming.\n\nThe predicted effects of global warming are many and various, both for the environment and for human life. These effects include sea level rise, impacts on agriculture, reductions in the ozone layer , increased intensity and frequency of extreme weather events, and the spread of disease. In some cases, the effects may already be being experienced, although it is impossible to attribute specific natural phenomena to long-term global warming. In particular the relationship between global warming and hurricanes is still being debatedFour new papers correlating climate change with increased hurricane intensity seem to be making the case that the two phenomena are linked , a draft WMO statement acknowledges the different viewpoints .

There are a number of different sites, depending upon what  area you are interested in. I know mostly about US sites, so if you're trying to find out about other areas/countries/continents, this may not help.\n\nFor a few Western US states, this is a very good site:\nhttp://www.wrcc.dri.edu/CLIMATEDATA.html\n\nThis gives a list of NWS offices in the US, but some of the local offices are good for providing data, other are not. You have to fish around to find what you want.\nhttp://www.nws.noaa.gov/organization.php

Carbon dioxide (which is emitted form cars) is the major gas from gases contribute to greenhouse effect, other gases cuase this effect like water vapor, methane, nitrous oxide,and CFC's
