Global warming occurs when excess greenhouse gases trap heat in the earth’s atmosphere, causing climate change. This can lead to rising ocean levels and stronger storms. Burning fossil fuels releases more greenhouse gases, causing an excess. Some experts disagree on whether global warming is a real threat, but steps are being taken to reduce waste and emissions.
The global warming effect describes what could happen if the world’s climate warmed. Indeed, the global warming effect states that excess greenhouse gases released into the air will trap the sun’s heat in the earth’s atmosphere. The buildup of that heat will warm the earth, causing climate change. Climate change can cause devastating effects on the planet and on those who live on it. Such effects can take the form of rising ocean levels and stronger storms.
Excessive greenhouse gases are the culprits for the global warming effect. Usually, when the sun shines on the earth and warms it, a natural amount of greenhouse gases, such as carbon dioxide and water vapor, trap some of the heat and keep the earth warm, just like the glass in a greenhouse. However, some of that heat can also escape into space. When fossil fuels are burned, more greenhouse gases are released into the air, causing an excess. Instead of allowing heat to escape into space, gases in the atmosphere will reflect more heat than needed back to the earth.
The effect of global warming can be far-reaching and devastating. Warmer ocean water can generate bigger and stronger storms and can also lead to an imbalance in ocean flora and fauna. Additionally, warmer temperatures can cause ice sheets to melt. All that ice melt can cause ocean levels to rise. Also, without ice, animals, such as polar bears, that depend on ice will suffer.
There are those who disagree that the effect of global warming is a threat. Some experts cite facts that claim the earth actually cooled over a period of decades. Other researchers point to ice rafting and other evidence to indicate that the earth may have a cooling, rather than a warming, trend. Other scientists agree that a warming trend is occurring, but that it is natural. Looking back at the history of the earth’s climate reveals a warming and cooling trend, and the earth, they say, is simply in a warming period.
Despite arguments about whether or not the effect of global warming is a real threat, there are steps being taken in an effort to reduce waste. People are encouraged to save energy and reduce emissions in various ways. Compact fluorescent bulbs use less energy. Therefore, they require fewer fossil fuels to burn to create electricity. Cars have also become more fuel efficient, so there are fewer emissions released into the air.
