Global Warming and the Green House effect.

Extracts from this document...

Introduction

What is Global Warming?

Global Warming is the increase in the Earth’s average temperature, which in turn causes changes in the climate. A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and it may have an effect on plants, wildlife and even humans. Scientists say that global warming is caused by us humans by using too much of carbon dioxide in our daily routine.

The Green House Effect

The Green house effect is the rise in temperature that the Earth experiences because some gases in the atmosphere such as carbon dioxide, nitrous oxide and methane trap energy from the sun. These gases are known as the green house gasses,

Middle

CFCs (chlorofluorocarbons) from aerosols, air-conditioners, foam packaging and refrigerators. These are the most damaging of the green house gasses.Methane is released from decaying organic matter such as peat bogs, swamps and waste dumps.Nitrous oxide is given out from car exhausts, power stations and agricultural fertilisers.

When do you send green house gasses in to the air?

Conclusion

One thing that is good that the colder parts of the world may now be able to crow crops as before it was to cold and the climate was not right for the crop to be grown.

What we should do in the future?

  • Save electricity, when we use electricity we help put green house gasses in to the air by turning of lights and televisions off after use would be a great help.
  • You can save energy by sometimes walking, riding a bike or taking the bus.
  • If we plant more trees and cut down less would be help. This is because trees absorb carbon dioxide and carbon dioxide is the main green house gas.

    The alternative source of energy is renewable energy and is produced in many ways using the sun, wind, tide and waves. The first form of renewable energy that we use is Solar Power. There are three main ways that we use our suns energy; Solar Cells contain light sensitive cells that convert light directly into electricity.

  1. The Green House Effect

    CO2 removed by dissolving into rain which reacted to form carbon compounds in rocks. CO2 was also removed by dissolving into the oceans. Later groups of one-celled organisms started to grow. They were the bacteria or prokaryotes. These creatures were the earliest evidence of life on earth and they were also the first organisms to develop photosynthesis.

  2. Greenhouse Effect.

    This process works by the principle that certain atmospheric gases, (or greenhouse gases) allow short wave radiation from the sun to pass through them unabsorbed, while at the same time absorbing some of the long wave radiation reflected back to space.
