Introduction

Global warming is the gradual increase in the average temperature of Earth’s air, or more accurately the lowest part of the troposphere (the layer of the atmosphere that has contact with the surface of Earth). Recently this has been increasing at a faster and faster rate. The average global temperature has increased by 0.74°C over the past century, and most of this increase has happened during the past couple of centuries. Below is a graph of the Average Global Temperature measured each year. The values jump up and down rapidly, this is due to various Earthly Cycles, but the general increases and decreases can be seen. Up until about 50 years ago there were times where the temperature increased but then there was ‘global cooling’ (the opposite of global warming) where the Earth recovered so that the general temperature stayed roughly the same over a long period of time. Since 1950, this has not happened nearly as much, with just a

       Below shows a graph on how worrying our situation is already. The graph shows the increase and decrease of average temperature over the past two millennia, the main point is that until recently, all the global ‘warmings’ have evened themselves out, but all these increases in temperature have not been nearly as massive as that over the past century. There is only so much that Earth can ‘heal’ itself.

First, to tackle this problem we need to understand what actually causes global warming before we can actually tackle it. Because to tackle the problem, we need to tackle the causes.

       The reason that the global temperature fluctuates so much is that the Earth goes through natural, internal processes such and external factors. These are due to solar activity, changes in the Earth’s orbit and things such as volcanic emissions. These activites bring the temperature up for a while before it goes back down. The irreversible change comes from greenhouse gas emmisions.

       Greenhouse gases are substances that cause the ‘Greenhouse Effect’.

Conclusion

       This picture shows what a nuclear power plant looks like. Even this produces emissions but for the amount of energy it produces, it is very small. Also, there have been plans proposed for the ‘watering down’ of the emissions so that the gases do not escape into the atmosphere but form diluted acids.

    Global Warming - Is it man Made?

    Scientists have found out trough fossils, that the sea level rises faster than at any time in the past 2,100 years. It is at least one fact, that some places have become smaller on many islands like the beaches.

    The majority of the ozone (about 97 %) found in the atmosphere is concentrated in the stratosphere at an altitude of 15 to 55 kilometres above the Earth's surface. In recent years, the concentration of the stratospheric ozone has been decreasing because of the build-up of chlorofluorocarbons in the atmosphere (see stratospheric ozone depletion).

    This may happen more rapidly than the species that depend upon them can adapt. A decline in biodiversity and in the goods and services provided by most ecosystems is a likely result. A lengthening of the growing season is predicted for some high latitude regions.

    However it's not always reliable as at some times there may not be any wind. Suitable areas of land are usually near the coast and are very expensive. Also, wind farms are very loud when generating energy therefore if they are built near public houses, the residents will be very angry and agitated as they will have many sleepless nights.

    During the earth's history there have been warmer periods, millions of years ago. However this is the most rapid rise in temperature since the end of the last ice age. So evidence is mounting that we, mankind are affecting the global climate, and the current warming has exceeded the natural fluctuations.

    There will be hotter, longer heat waves and more intense storm systems. Forests, farms and cities will face troublesome new pests and more mosquito-borne diseases. Changing regional climate could alter forests, crop yields, and water supplies. It could also affect human health, animals, and many types of ecosystems.

    Most scientists agree that the global temperature is rising. They do not agree on more specific elements of the issue: How much will it warm up? What will happen if it does warm up? How far are humans responsible? What should we do to stop it? Scientists believe that if we go on producing gases at the rate we
