Yes. They can and they do. Any increase in the level of carbon dioxide or methane in the atmosphere will result in an increase in average global temperatures. This typically results in evaporation of additional water vapour, creating a slight amplifier effect, to further increase surface temperatures.
Mars. With an average surface temperature of -63 degrees Celsius, it is much colder than Earths average of +14 degrees Celsius - but it is the closest to it.
The atmosphere. The ozone layer absorbs UV radiation, and atmosphere also controls temperature through the greenhouse effect, which allows the earth's temperature to be suitable for life. If there was no greenhouse effect then the earths average temperature would be -14oC instead of the actual 15oC.
greenhouse effect
Ozone at ground level is a pollutant. It is a greenhouse gas.
It raises the temperature and makes it hotter through the greenhouse effect.
Mercury has an average surface temperature (67°) closest to the Earths average surface temperature (14°C). The temperature on Mercury varies a lot though - you could argue that Mars is closer in temperature.
The greenhouse effect
Venus has a very thick atmosphere of Carbon dioxide. Its average surface pressure is a crushing 93 bar, or 93 times that of Earths. Venus is the hottest planet, as it is close to the sun, but additionally, its thick arbon Dioxide atmosphere holds the heat very effectively like an oven - or greenhouse.

global warming is the increase in the average temperature of earths near surface :D
Due to the Greenhouse Effect, Earth's temperature is continually rising. If the trend does not change, the Earth's annual temperature will continue to rise, causing significant ecological problems.
They absorb radiant energy emitted by Earths surface
The greenhouse effect is more pronounced for the earth's surface. Heat rising from the surface is trapped by greenhouse gases. These warm gases heat the air around them as well, also, as the earth' surface again.

Carbon dioxide acts as a greenhouse gas and retains heat radiation from the sun, which, combined with other greenhouse gases helps to maintain the earths surface temperature. Without the presence of CO2 in the atmosphere, most of the solar radiation would not be retained and thus the surface temperature would be very low and unable to sustain human life.
