Global warming is something is something that has been happing to our world since the begin of green house gases. But until now we dint know the damage it could create and the things that are happening to our world. Since our planet got industrialized green house gases have been destroying our ozone layer and raising the temperature of our planet. By raising the temperature of our planet the polar ice caps are melting and raising our world’s water levels. What effect can come of this, our costal cities will all be other water. But it’s hard to say when this can happened, but we have to understand that its something inevitable if we don’t change the way we spend our planets natural resources. So the sooner we can stop doing what we are doing the better outcome it will be for our planet.
