You honestly don't know how science figures things out? or are you trying find out if *I* know how science figures things out. They examine preserved ice core sample that go back several thousands of years and measure the gases trapped inthe ice. Much older than that and the ice looses the gas from being crushed. The amounts of various gases tells scientists what was going on (in gneral terms you understand) at various times in Earths recetn past. Other evidense can be determined from fossil records indicating what froms of plant life and in what amounts were present, at various points in our history. Knowing what was helps figure out what's going to be. Again in general terms. You wont be able to set your watch by it but it can shed alot of light on what has happened in the past. Of course scientists are always looking for more info to gain a better understanding of what was... it's a "...to be continued" story > The Duke analyses examined solar changes over 22 years > versus 11 years used in previous studies.

At one time we thought flight was impossible and to dream of such nonesense was foolish kids stuff... You just never know until you give it a try.
