belief‚ this is a fact. Global warming‚ by definition‚ is a gradual increase in the overall temperature of the earth ’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide‚ CFCs‚ and other pollutants. The greenhouse effect is the trapping of the sun ’s warmth in a planet ’s lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet ’s surface. In simpler terms‚

The difference between weather and climate is that weather consists of the short-term (minutes to months) changes in the atmosphere. Most people think of weather in terms of temperature‚ humidity‚ precipitation‚ cloudiness‚ brightness‚ visibility‚ wind‚ and atmospheric pressure‚ as in high and low pressure. There are lots of factors that influence our climate Elevation or Altitude effect climate Normally‚ climatic conditions become colder as altitude increases. “Life zones” on a high mountain reflect

Well mixed and is the site and source of our weather. Primary recipient of air pollutants. Stratosphere: The layer of Earth’s atmosphere between 10 miles and 40 miles above the surface that contains the ozone shield. Mixes only slowly; pollutants that enter it remain for long periods of time. Weather: The day-to-day variations

across the world believe that human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases‚ aerosols (small particles)‚ and cloudiness. A recent report of the Intergovernmental Panel on Climate Change states that the largest known contribution comes from the burning of fossil fuels‚ which releases carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared

from the Earth ’s surface by carbon dioxide and other gases in the atmosphere‚ causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise‚ and creating many problems that will begin to occur in the coming decades. For the last 10‚000 years‚ the Earth ’s climate has been extraordinarily beneficial to mankind. "Humans have prospered tremendously well under a benign atmosphere‚" (Bates 28). <br><br>Today‚ however‚ major changes are taking place

global climate patterns. An increase in the earth’s atmospheric and oceanic temperatures is widely predicted to occur due to an increase in the greenhouse effect resulting from pollution. Atmosphere carbon dioxide (CO2) is known as a Greenhouse gases‚ which means the increased levels of carbon dioxide in the atmosphere can lead to global warming which could affect the world’s environment. Scientists have determined that humans are responsible for the increases by use of cars‚ industries‚ and forest fires

have been alternating it. The atmospheric greenhouse effect naturally keeps our planet warm enough to be livable. Sunlight passes through the atmosphere. Light-colored surfaces‚ such as clouds or ice caps‚ radiate some heat back into space. But most of the incoming heat warms the planet’s surface. The Earth then radiates some heat back into the atmosphere. Some of that heat is trapped by greenhouse gases in

Name: ____________________________________________ Period _________ Date _________________ Earth’s Dimensions Unit: Layers of the Atmosphere & Earth’s Interior INTRODUCTION: The Earth’s atmosphere is divided into 4 layers. There is a boundary where each layer ends and a new one begins and a name is given to this boundary – a pause. Distinct temperature differences are found within each layer. For example‚ at the stratopause‚ the temperature stops increasing with altitude
