Is Global Warming Caused by Humans?

I have not yet decided for myself whether or not I think Global Warming is caused by humans.  I have read and reviewed so much data in the last month or so and I still feel as if I don’t know enough.  I would love to believe all the statistcs I read, but I can’t.  There are so many statistics that contradict the other.  Scientists and experiments would be fixed is some places and so believing what you hear and see doesn’t mean it’s always right.  I do believe that global warming is a real issue that definitely could cause potential harm to our Earth, but I believe it is due to many different causes.  I believe that global warming is mostly a naturally occuring process that has been occuring for many centuries and will continue until the end of the Earth.  But I do think it is increasing at a faster rate because of human impacts.  I definitely think that we, as humans, have had some substantial influence on heating the Earth.  I think whether or not we are the main cause, we should start to fight back.  Start looking at ways to lower the CO2 emisions and the burning of fossil fuels.  Doing this would never hurt.  I don’t think we should wait until we are in immediate danger to do something about it.  We should start now and hope for the best of outcomes!
