Research Papers / Need points/advice on Global Warming (I am opposed to it) [4]

I am writing an argumentive essay about global warming, and have decided that I am opposed to it. I have so much info on the topic , however I don't know how to get started.

I would like to say that humans are not the cause of these recent climate changes, but I feel my points are not as strong as they should be.

Another point I was thinking I could use is that Global Warming is a scam

Any help is appreciated,
thanks
