These ice caps are located at the north and southerly poles of the Earth, and take up a large potion of the earths water. Ice caps fluctuate from year to year, growing and shrinking with weather changes. Greenhouse gasses are causing these ice caps to melt more and more every year though. If the ice caps were to melt completely, it would raise our ocean level ten to twenty stories about what it is now. This w ould circulate places like Nova Scotia, Vancouver, and New York completely under water. Scientists are not really quit sure what will happen with green house gases, whether they will possess a flood from melting the ice caps, or whether it will send us into another ice age.

Greenhouse gasses may also change the weather, making our climate either much hotter or much cooler. Ice caps and leaves have one affaire in common, one small change in the weather can change them- and they will change the world.The Sahara desert is known as the largest dessert in the world, it covers a third of the continent of Africa. The thing abou t the desert is that it is always changing, new vegetation is sprouting and animals are dying and being born. During the day the desert is very hot, about 50 degrees Celsius, but at night time temperatures can drop very low. In the night is when the desert rains, for temperatures are too hot during the day for clouds to accumulate above them, and water is limited so there isnt much precipitation.
