Why I chose "Global Warming" as my topic?

I chose "Global Warming" as my topic because the earth is the only home we have. Global warming is causing summer nights as hot as summer days. Summer time gets longer and longer each year. That way people will get too much heat and more people will start turning on the air conditioner. One thing can spare to lots thing. It also causing less snow in fall in the high altitudes and winter time will get shorter and shorter each year. Global warming is a huge problem happening now. The good news is that we still have time to solve the problem. During several glacial periods, or ice ages, many parts the world were much colder than they are now. These periods alternated with shorter periods when the ice melted, and the climate was generally warmer.
