Global Warming

Introduction

Global Warming What is Global Warming? Global warming affects everyone. It is a process where the Earth is heated up and therefore in the future Global Warming could change the life of the human race for ever. Give one or two examples of how life would change. Don't explain it.. you will explain it later. Just give a quick example or two. The process of Global Warming is basically when solar radiation is sent from the Sun to the Earth. The solar radiation then passes through the atmosphere and hits the Earth's surface. Some of this solar radiation warms the Earth's surface and some is used up by plants and trees. But the rest of it is reflected back up into space, to get to space it first has to pass through the atmosphere again. And this is where the problem is, the greenhouse gases in the atmosphere, which are made up of CO2, methane etc, stop the solar radiation from passing through. ...read more.

Middle

etc There is a lot of evidence backing up Global Warming; this evidence can also be shown in graphs. Scientists have studied Antarctica for a long time and they say that the icecaps are melting. Polar bears have to swim up to 60miles to reach an icecap where they can rest. Surely this is not how Antarctica was. It was much bigger than it is now, and the only reason it has shrunk is because temperatures (by how much?) are rising which are causing the icecaps to melt (by how much). And there is only one reason why this is happening: Global Warming. On the right you can see how much of Antarctica has melted away. Why is Global Warming happening? Global Warming is happening because of us. We are the main cause of Global Warming. Of course it is the CO2 that is stopping solar radiation from going back into space but the CO2 is coming from the fossil fuels and the deforestation (how does deforestation contribute to global warming? ...read more.

Conclusion

The graph below proves that CO2 is what is causing the Earths' temperatures to warm up, because it clearly shows that the more CO2 we have in the air the higher the temperatures. It also shows that when CO2 levels drop the temperatures drop as well. Instead of the above paragraph, use the diagram in your textbook to produce a simple cartoon that shows global warming and where greenhouse gases come from. It would be a much better way of presenting this information - you would get extra marks for this. Where do greenhouse gasses come from? The major greenhouse gas, carbon dioxide, is produced by human activity. When someone burns something e.g. wood or coal then carbon dioxide is released. The high demand for things like mahogany and other expensive and fashionable woods ongoing use of fossil fuels as an energy source is all causing Global Warming. Like I said, put this information into a simple cartoon.. or even do a bullet point list explaining each idea. But a cartoon would be much better ...read more.
