Some people are denying the fact that Global Warming is happening. They say that there isn’t enough evidence to support Global Warming. But this is false, because the evidence is all around them. Al Gore, from the film an inconvenient truth, said that it is hard to get a man to believe when his salary depends on him not believing. I think this is the case with Global Warming because it is mainly big oil companies that make millions out of burning fossil fuels and contributing to Global Warming that do not want to believe that Global Warming is happening. Have little speech bubbles that show the different opinions of different people – 1) owner of oil company (lil pic of a fat man) 2) environmentalist 3)scientists (use what ur saying below.. e.g. “I have been studying Antarctica for a long time and have come to the conclusion that the ice caps are melting at Xcm per year – this graph shows what im saying) 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? Basically, trees absorb CO2 from the atmosphere to use in photosynthesis. Which releases oxygen. When trees are cut down, there are fewer trees to absorb the CO”, so more CO2 remains in the atmosphere). We are the reason why fossil fuels are being exploited, we are why forests are being deforested and then burnt. We are the victims of our own crimes. And we have the knowledge and common sense to stop Global Warming from destroying our lives. So why aren’t we acting?
When fossil fuels are burnt, carbon dioxide is released into the atmosphere. Carbon dioxide and other harmful gasses that go up into the atmosphere are called greenhouse gasses; these are called greenhouse gasses because they act like a greenhouse. They trap the heat inside them. CO2 is a colourless gas that traps infrared radiation. As most of the energy that leaves the Earths’ atmosphere comes in this form there is a huge problem with CO2, because as long as CO2 is present more and more infrared radiation is going to be trapped inside the Earths’ atmosphere.
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
