Introducton of Global Warming


These days’ people care more about the greenhouse effect than ever. But on the planet they burn fossil fuels such as coal, gas and oil to get power. So that operation increases the amount of Carbon dioxide and other toxic gases in the atmosphere. By that the solar heat well reach the earth and increase the heat of the earth. So many nature disasters will happen for example we can notice the number of Category 4 and 5 hurricanes has almost doubled in the last 30 years. And other affect is will increase the temperature for example, in Greenland the flow of ice from glaciers in has more than doubled over the past decade. If the ice starts to melt or it becomes water the level of the sea will rise and so more flooding well happen. Also there are many affect on the animal such as polar bears can’t live if the ice becomes water. Moreover there is the affect on human, For example it causes some kind of cancer on the skin because the sun waves come direct from the sun without any filter by layer ozone.
