…in the burning of coal and oil since the late 1940s has led to ever increasing concentrations of carbon dioxide. The resulting "greenhouse effect", which allows solar energy to enter the atmosphere but reduces the reemission of infrared radiation from the earth, could…

…about global warming is what causes it to occur. Gases such as carbon dioxide, methane and nitrous oxide, which are known as greenhouse gases, all build up in the atmosphere of the earth. All these gases make it so that it becomes harder for the radiation…

…runaway greenhouse effect the surface temperature is extremely high, and volatile gases in the atmosphere would kill instantly any known forms of life. Mars, on the other hand has an atmosphere not that different from the Earth, although very cold it is closer…

…The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane, which comes mainly from animal manure. Other gases like nitrogen oxide and chloroflurocarbons, man made gases, get caught in the atmosphere as well…

…a huge degenerative environmental problem that has preoccupied scientists for decades, since it concerns the entire biosphere. This climatic change, potentially caused by an ever-increasing hole in the ozone layer, is known as the greenhouse effect…

…Rainforest region, has caused numerous global climate changes, particularly in the water cycle and greenhouse effect. Characteristics of the Amazon Rainforest region The Amazon Rainforest is the largest rainforest left of earth; it is about the size…

…increasing concentrations of carbon dioxide. The resulting "greenhouse effect", which allows solar energy to enter the atmosphere but reduces the remission of infrared radiation from the earth, could lead to a warning trend that might affect the global climate…

…the company, "the world's most environmentally friendly auto maker." Environmentalists sight the hypocrisy in this statement, since the average Excursion will emit 130 tons of carbon dioxide, the predominant source of greenhouse gases that perpetuate global…

…into the atmosphere by a process called 'global warming' or the 'greenhouse effect'. Some of the chemicals that are believed to contribute to the greenhouse effect are carbon dioxide (CO2), nitrous oxide, halogen gases and CFCs. These chemicals cause the climate…

…pollutants, such as sulphur or greenhouse gases. The use of nuclear energy in place of other energy sources helps to keep the air clean, because there isn't any harmful output after a nuclear reaction. Nuclear energy also avoids ground-level ozone formation…
