Some Global Warming Questions


Hey, all. I read Jana's questions in comments on one of the posts. Good questions, Jana! I have some of the same questions, and here are some additional questions for consideration:

1) Can the noted changes in our earth system be explained by natural variability (including the observed changes in solar output)?
2) How important and reliable are paleoclimatic trends in predicting the future when it comes to global warming or cooling?
3) How reliable is the IPCC Special Report on Emission Scenarios in determining the range of future possible greenhouse gas concentrations?
4) What factors do the IPCC and other trusted sources use to calculate these scenarios?
