presentation begins with a look at the atmosphere‚ since is where the action is in discussions on global warming and ozone layer depletion and anchors with suggestions for local‚ national and global action. THE ATMOSPHERE The Earth and other planets of the solar system are each enclosed in a thin shell of gas called the atmosphere. If the Earth is compared to an orange‚ the atmosphere can be considered the skin of the orange. Layers of the atmosphere Scientists have developed three different

Chapter 1 1.1 1. Meteorology is the scientific study of the atmosphere and the phenomena that we usually refer to as weather. Weather is constantly changing…it refers to the state of the atmosphere at a given time and place. Climate is a description of aggregate weather conditions. 2. Temperature of the air‚ humidity of the air‚ type and amount of cloudiness‚ type and amount of precipitation‚ pressure exerted by the air‚ and the speed and direction of the wind. 1.4 2.

on it. Maybe it was true at one time‚ however not anymore. One of the reasons it’s not true is that the most vulnerable part of the earth ecological system is the atmosphere. Vulnerable because it is just so thin‚ if you had a big globe with a varnish on it the thinness of that varnish is pretty much the same as the earth’s atmosphere compared to the earth itself. Therefore it’s thin enough for us to be able to change its composition. The basic science of this theory of global warming the sun

have been many explanations toward the main causes of the increased warming of the planet. On one hand are the environmentalists who believe that the major cause of this increased warming of the planet is the increase in greenhouse gases in the atmosphere induced by human activities. On the other hand‚ the scientists believe that there are natural causes of global climate change. While the supporters of the man-made theory of global climate change reason that the major greenhouse gas causing global

photosynthesis‚ it absorbs CO2 from the air. When a tree dies‚ carbon is transferred from the forest to the soil and eventually into the air as CO2. When a factory uses energy to make products‚ it emits carbon into the atmosphere. There are many such exchanges of C02 between the earth and the atmosphere. Our activities distribute carbon and can affect nature’s balance. We can reduce our impact on the natural carbon cycle by making smart choices and reducing our carbon footprint. The most effective way to reduce

ABSTRACT MODELING THE IMPACT OF CLIMATE CHANGE ON WATER RESOURCES CASE STUDY: ARKANSAS RIVER BASIN IN COLORADO There is mounting evidence that amount of carbon dioxide is being increased which can lead to changing the global climate drastically during this century. Climate change can have important effect on the water resources and water demand like urban and agriculture uses. The effects of climate change have been explored in the Arkansas River Basin in Colorado which is one of the major

compound‚ carbon dioxide. In 1870 the amount of carbon dioxide in the atmosphere was 290 parts per million. 144 years later‚ to this very date‚ it has risen to over 400 parts per million. But why does this cause a problem you may ask‚ well it is now universally accepted that an increase in levels of carbon dioxide in the earths atmosphere causes temperature to rise. Having said this‚ the absence of carbon dioxide in our atmosphere would have devastating consequences including the eventual extinction

Notes These are some of the key items I want you to understand: Difference between weather and climate The difference between weather and climate is that the weather is in one place and the climate is the location 7 Main components of the atmosphere: Variables that define what the weather is! 1. Pressure 2. Temperature 3. Wind 4. Humidity 5. Cloud Cover 6. Precipitation type and amount 7. Visibility (distance one can see horizontally) Two types of measurements: examples The two types of

<b>The Greenhouse Effect</b> <br>The earth’s climate is predicted to change because human activities are altering the chemical composition of the atmosphere through the build up of greenhouse gases primarily carbon dioxide‚ methane‚ and nitrous oxide. <br> <br>Energy from the sun drives the earth’s weather and climate‚ and heats the earth’s surface. This causes the earth to radiate the energy back into space. Atmospheric greenhouse gases (water vapour‚ carbon dioxide‚ and other gases) trap some

dioxide‚ ozone‚ and methane. All of these gasses escape slowly from the atmosphere‚ therefore the heat stays here longer in a short of warm airy blanket. Without the occurrence of the greenhouse effect scientist say that the earths average temperature would be around 30 degrees C. or 50 degrees F. There are many greenhouse gasses that can trap the infrared rays of the sun. Carbon dioxide can be released into the atmosphere in several ways‚ the bulk of it is produced by car exhaust‚ deforestation
