Global warming
What is global warming?Global warming is the change in the overall temperature in the atmosphere.A example would be Antarctica,the dramatic change in weather would kill off the population of polar bears,they will have to find a new home because they aren't use to that type of weather. They have to find food near where they are and they have to find a way to survive after all the ice melts.This is global warming and how it effects us and the things around us.
