Unfortuntaley I dont know any, along with most of the population so I'll have to base my understanding on what I hear on the news and trust they dont exaggerate things. They should have more actual scientists in the media explain how they things work but instead we have a lot of people telling us to be very worried based on "scientific consesus", but no real scientific explanation. I understand the basic idea about how they model climate based on models in computers but the climate of the planet is so complex involving so many factors I find it hard to believe that accurate predictions can be made based on this. Then when the predictions dont match the model it makes me at least think that the theory behind the prediction could be wrong. When you then add to this that this is now a political and econimic issue its easy to see that reporting can be prejudiced because of whats at stake.
