You're right! It has varied over time. I'm guessing you didn't see Al Gore's an inconvenient truth. It tends to go up and down throughout the years. But if you look at the chart from say 500,000 years ago it is hotter now then it has ever been. In the last 10 years we have had 9 of the hottest years. 2007 being the warmest.
3 degrees is NOTHING. You're right! But say it went up another 1 degree. The process gets faster and faster. The carbon emissions we put off with cars, factories, power plants etc. build up those greenhouse gases making it get hotter and hotter over time.
Maybe the science is wrong. Maybe this is just another one of those times where it's hotter than normal. But how does it hurt the way you live life? If we keep relying on fossil fuels we will still run out. If we keep mass producing cars we will continue to see an increase in temperature.
I don't know a lot on this topic considering i'm only 12. But think, if the temperature has gone up 3 degrees in the last 10 years what will the temperature be like when my kids are 20?
