Queeny- Research Process

Have to say I'm having a difficult time understanding the proposal assignment. Even though I have chosen my topic which is Global Warming I still think is a huge issue that make the research process a little difficult for me. I need to narrow down my issue or change my topic to make this assignment more interesting for me. I want to learn from this assignment as well as engage and have fun with it. Well, to get a better understanding of the assignment I need to ask Professor Jolly to explain it to me a little more. I still need help. I feel completely lost.
