"Hey Morgan with what precision Can Scientists really predict the future effects of global warming on earth?"

Not possessing 20:20 foresight I can't answer that question. What I can tell you is that so far the predictions have been well within the margin of error and are getting better.

If you are correct there are a lot of two-legged creatures on this planet lacking eyes, or a brain, or both. But you know what my opinion is.
