The causes of global warming Introduction. With the rapid development of economy, the issue of the causes of global warming has been brought into Definition. First of all, according to my research paper topic “the causes of global warming”. I want to begin with the Description of the causes 7/24/ · A.1 There are various causes of global warming both natural and manmade. The natural one includes a greenhouse gas, volcanic eruption, methane gas and more. Next up, manmade causes are deforestation, mining, cattle rearing, fossil fuel burning and more Causes of global warming. The greenhouse effect; Radiative forcing; The influences of human activity on climate. Greenhouse gases. Water vapour; Carbon dioxide; Methane; Surface-level ozone and other compounds; Nitrous oxides and fluorinated gases; Aerosols; Land-use change; Stratospheric ozone depletion; Natural influences on climate.

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, write a paragraph about causes of global warming.
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, or CO2. Other contributors include methane released from landfills, write a paragraph about causes of global warming 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 atmosphere 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, write a paragraph about causes of global warming, 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 CO2none 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.
