Scientists attribute the global warming trend observed since the mid th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping · Paragraph on Global Warming – Words for Classes 4 and 5 Children. Global warming is a hike in the average global temperature on earth. Burning of excess fossil fuel and the release of toxic fumes into the atmosphere is the major cause behind global warming. Global warming can have disastrous effects on living organisms · Gases produced by the burning of fossil fuels prevent the heat from leaving the atmosphere. These greenhouse gasses are carbon dioxide, chlorofluorocarbons, water vapor, methane, and nitrous oxide. The excess heat in the atmosphere has caused the average global temperature to rise overtime, otherwise known as global warming
Expository Essay: Global warming causes and consequences essay
The average temperature of the Earth is rising at nearly twice the rate it was 50 years ago. This rapid warming trend cannot be explained by natural cycles alone, scientists have concluded. The only way to explain the pattern is to include the effect of greenhouse gases GHGs emitted by humans.
Current levels of the greenhouse gases carbon dioxide, methane, and nitrous oxide in our atmosphere are higher than at any point over the pastyearsand their ability to trap heat is changing our climate in multiple ways. To come to a scientific conclusion on climate change and what to do about it, the United Nations in formed a group called the Intergovernmental Panel on Climate Changeor IPCC. The IPCC meets every few years to review the latest scientific findings and write a report summarizing all that is known about global warming.
Each report represents a consensus, or agreement, among hundreds of leading scientists. One of the first things the IPCC concluded is that there are several greenhouse gases responsible for warming, and humans emit them in a variety of ways. Most come from the combustion of fossil fuels in cars, buildings, factories, and power plants. The gas responsible for the most warming is carbon dioxide, cause of global warming paragraph, or CO2.
Other contributors include methane released from landfills, natural gas and petroleum industries, and agriculture especially from the digestive systems of grazing animals ; nitrous oxide from fertilizers; gases used for refrigeration and industrial processes; and the loss of forests that would otherwise store CO2.
Different greenhouse gases have very different heat-trapping abilities. Some of them can trap more heat than an equivalent amount of CO2. A molecule of methane doesn't hang around the cause of global warming paragraph as long as a molecule of carbon dioxide will, but it is at least 84 times more potent over two decades.
Nitrous oxide is times more powerful than CO2. Other gases, such as chlorofluorocarbons, or CFCs—which have been banned in much of the world because they also degrade the ozone layer—have heat-trapping potential thousands of times greater than CO2. But because their emissions are much lower than CO2cause of global warming paragraph, none of these gases trap as much heat in the atmosphere as CO2 does. The more greenhouse gases in the atmosphere, the more dramatic the effect, and the more warming that happens.
Despite global efforts to address climate change, including the landmark Paris climate agreementcarbon dioxide emissions from fossil fuels continue to rise, hitting record levels in Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and and habitats, rising seasand a range of other impacts.
