8. These pictures taken by NASA satellites show just how serious the problem of the melting ice caps actually is. This shows the change in the size of the polar ice caps in just thirty years. All the ice that has melted has gone into the sea to increase the levels by 2mm a year. This is growing though, as the temperatures rise and melt even more ice. Ice caps 1973 Ice caps 2003

11. Scientists have discovered that the polar ice caps are one of the Earth’s natural defences against the full heat of the Sun. It is believed that the ice reflected a lot of the suns heat back into space and so keeping the Earth at a temperature suitable for the habitation of humans, plants and animals. Because the carbon dioxide pollution is trapping the suns heat in the Earth’s atmosphere, the ice caps are melting and no longer have the power and surface area to reflect the majority of the Sun’s heat. This results in the Earth getting even hotter as the full intensity of the sun slowly works its way to the atmosphere and then gets trapped by the carbon dioxide layer.

13. As the ice caps melt, many species who live in that area will become extremely endangered or extinct. Species such as the polar bear, penguin and arctic seal will find that their homes disappear into nothing and so will die out. Many eco systems will break down and while some species will thrive and their numbers will become increasingly huge but other animals will die out as their food becomes scarce.
