Climate change and atmosphere

in the darkest regions of space, the temperature of -450 degrees Fahrenheit is cold. Closest to our sun, temperatures reach thousands of degrees Fahrenheit.What makes the Earth's climate is so mild? The separation of the ground by extreme weather and inhospitable room is a cocoon of gas 500 miles thick is the atmosphere.All planets have an atmosphere, a layer of gas that surrounds them. the Sun's atmosphere consists of hydrogen, while the earth is composed mainly of nitrogen and oxygen. Carbon dioxide, ozone and other gases that are present. These gases keep our planet warm and protect us from the immediate effects of solar radiation. Without this control, the earth does not sustain life.

the troposphere, stratosphere, mesosphere, ionosphere and exosphere: The atmosphere is composed of several layers. Closer to the Earth is the troposphere. Most clouds in the sky are in the troposphere and in this layer of atmosphere that we over time.Extension of 10 kilometers from the Earth's surface, contains the troposphere a variety of gases: water vapor, carbon dioxide, methane, nitrous oxide, and others. These gases help retain heat, a part of what then re-emitted to the earth's surface warm.Above the troposphere to the stratosphere, including the ozone layer. The stratosphere extends from 10 to 30 miles above the earth's surface.
Ozone molecules, which are concentrated in this layer absorb ultraviolet radiation from the sun and protect against the harmful effects.

Thirty to 50 miles above the surface is the mesosphere, the coldest part of the atmosphere. Above the mesosphere, a layer called the ionosphere (also known as the thermosphere), begin to heat things up. The temperatures in the ionosphere, which extends about 50 to 180 miles from the earth's surface can reach several thousand degrees Celsius. Beyond the ionosphere, the exosphere, which extends about 500 miles above the earth's surface.
It is the outermost layer of the atmosphere, the transition zone in the room.


The gas to help keep heat in the atmosphere of greenhouse gas emissions are credited. These gases, mainly carbon dioxide (CO2), absorb heat, instead of going into space. This greenhouse effect makes the world a welcoming place.However, the greenhouse gas emissions have negative effects, too. Human activities have increased the amount of CO2 in the atmosphere. Since late 1800, industrialized societies have fossil fuels such as coal, oil and natural gas burned, emit CO2 all these processes. In the past 25 years the amount has increased to CO2 in the atmosphere for approximately 8 percent. With more CO2 in the atmosphere, more heat is absorbed and retained higher temperatures.

Some scientific projects that could be of the next century, CO2 levels are doubled in the atmosphere, what they are today, leading to a rise in global temperature by about 3 degrees. Three degrees may not seem like much, but a few degrees can have serious consequences. could increase tropical diseases thrive as mosquitoes and other disease-carrying insects in a warmer climate. Sea levels could rise, and coastal cities like New Orleans and Washington, DC, could be hit by the storm surge. Prospero could dry farming areas and agriculture can change, causing chaos on the global economy.

It is possible that the recent warming is more of a natural cycle of warming and cooling of human action. Global climate change is on a scale of tens or hundreds of thousands of years, but scientists have only begun to study these effects in the last 150 years. However, most scientists agree that the weather affects our lives can affect climate. How you can determine what remains to be seen.
