Global warming, the effects are in the title! Apart from warming up the planet, global warming helps with desertification. The heat from the suns rays not only warms up the planet, but the sea. If this continues, the Gulf Stream will heat up and completely destroy the Arctic. The sea will become stagnant and will release deadly gases. This may kill all the life, but it is not the planet that will suffer, it is life. Life has been on earth for 3600 million years and it has been a survivor. We may not survive global warming but life will. The dinosaurs died and we came along, it will be the same again.
