Greetings!
Fortunately, there is a lot of information online about global warming. It's a fairly broad topic, though, so first, you should probably decide what focus you want your paper to have. You'll want to start with a definition of global warming, of course. Then, you may want to give a brief history of the debate about global warming. For some years, many scientists maintained that it was a myth. Recently, global warming has come into mainstream thinking as more fact than theory. Depending on whether this is for a science class or some other class, you may want to discuss the scientific reasons that most people now accept global warming as a real danger. And what are the dangers? What do the people of Earth have to look forward to if global warming is not addressed? Is it too late already?
I suspect that once you start doing internet searches, you'll find many helpful sites that can get you started. Once you've got some ideas fleshed out, let me know if I can help with some more questions or editing!
Thanks!
