sometimes used to refer specifically to climate change caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes. The term climate change, hence, has become synonymous with global warming. Any scientist will acknowledge that earth’s climate has always been changing. Increasing emissions into the atmosphere of carbon dioxide and other greenhouse gases (such as methane) have created the so-called “greenhouse effect,” leading to overall global warming

Thermosphere – temperatures rise rapidly with height, perhaps to reach 1500°C. This is due to an increasing proportion of atomic oxygen in the atmosphere. Which like ozone, absorbs incoming ultra-violet radiation. Mesosphere – temperatures fall rapidly as there is no water vapour, cloud, dust, or ozone to absorb incoming radiation. This layer experiences the atmospheres lowest temperatures (-90°C) and strongest winds (nearly 300km/hour). The mesopause, like the tropopause and stratopause, shows no change

controlling Earth’s climate resided primarily in the writings of science fiction authors such as Frank Herbert, Isaac Asimov, and Arthur C. Clarke. Today, planetary engineering is being discussed openly by scientists and policymakers in Congress, the UK House of Commons, and many other settings. Clarke’s advice apparently struck a chord: “Politicians should read science fiction, not westerns and detective stories.” Geoengineering can be thought of as intentionally manipulating Earth’s climate to

wavelength band(s) of the electromagnetic spectrum do they absorb radiation? In your answer, give three examples of greenhouse gases and their wavelengths of absorption. Greenhouse gases are gases in the atmosphere that allow light through but block infrared radiation that is reflected off of Earth’s surface, not allowing the heat to escape and thus causing long term heating effects on our climate. The greenhouse gases absorb some incoming light but the greenhouse effect is cause by the absorption

warming? Scientifically speaking it is describe as the gradual increase in the temperature of the earth’s atmosphere believed to be due to the green house effect. In this paper I will discuss the history or global warming and how it became the most talked about topic in environmental science. In addition I will describe various types of pollutions that we humans have contributed to making the atmosphere worst every year. Finally I will conclude the paper with a variety of solutions humans have begun

Atmosphere The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night. Dry air contains roughly (by volume) 78% nitrogen, 21% oxygen, 0.93% argon, 0.038% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water

“Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. 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 (thermal) radiation that are part of Earth’s energy balance. Changing the atmospheric abundance or properties

existed prior to the industrial period. Thus, the argument is cemented by the fact of logical truth. In addition, the manmade chemicals are typically polar molecules. Polar molecules contain a negative end and a positive end. Keep in mind, the earth’s anti-air defense system is the ionosphere, the sphere which makes city sized asteroids into watermelon sized meteorites. With polar molecules present in our troposphere, the accumulated electronegative pull of troposphere molescules upon ionosphere

Name____________________________ 1) Why is it that weather and climate can be confused at times? 2) What is needed to distinguish between the two? What makes it so difficult to come up with one value of the earth’s surface? Is a 1 degree warming over the earth’s surface is a valid concern? 3) What did the monks from 500 years ago discover? Why were they a good measuring tool? 4) The weather patterns seemed to be highly variable over the last 20 years. Droughts
