Model Essay for students on global warming.
Global warming starts with the greenhouse effect, which is created by the relationship between the radiation from the sun and the Earth's atmosphere. Human activity also introduces specific types of gases into the Earth's atmosphere. As of 2005, as a result of these circumstances, over the last 50 years, the average global temperature of the Earth has experienced the fastest growth rate in.
The effects of global warming or climate damage include far-reaching and long-lasting changes to the natural environment, to ecosystems and human societies caused directly or indirectly by human emissions of greenhouse gases.It also includes the economic and social changes which stem from living in a warmer world. Many physical impacts of global warming are already visible, including extreme.
Global warming is the increase of average world temperatures as a result of what is known as the greenhouse effect. Certain gases in the atmosphere act like glass in a greenhouse, allowing sunlight through to heat the earth's surface but trapping the heat as it radiates back into space. As the greenhouse gases build up in the atmosphere the Earth gets hotter. This process is leading to a rapid.
Almost a year after the story about attempts to silence NASA’s top climate scientist, many media outlets have reported on a new survey where hundreds of government scientists say they have perceived or personally experienced pressure from the Bush administration to eliminate phrases such as “climate change” and “global warming” from their reports and public statements.
Boosting energy efficiency: The energy used to power, heat, and cool our homes, businesses, and industries is the single largest contributor to global warming. Energy efficiency technologies allow us to use less energy to get the same—or higher—level of production, service, and comfort. This approach has vast potential to save both energy and money, and can be deployed quickly.
