"Try looking at paleo history. We see the same sorts of climate cycles in the past that we see now. We see more dramatic changes than the present. If you look at the past with an honest eye, the present simply isn't scary. Here is a graph showing the earth's temperature history. Look closely and tell me honestly, in what direction do you believe the overall temperature will be moving with or without us?"The issue isn't whether or not global temperatures have fluxuated in the past. They have. The issue is whether or not we are in a very short time span adversely influencing global temperatures ajd weather patterns and in the process inexorably modifying the planet in inway that is harmful not only to humans, but to many other species as well. I think we are, and so do may other scientists. What your graph doesn't make apparent to the layman's eye is that coinciding with many of those changes from warm to cold were devastating mass extinctions. Is that the future you want for your children and their children? Another Permian mass extinction?
