Viggen Posted December 29, 2004 Report Share Posted December 29, 2004 Thompson has spent his career trekking to the far corners of the world to find remote ice fields and then bring back cores drilled from their centers. Within those cores are the records of ancient climate from across the globe. From the mountains of data drawn by analyzing countless ice cores, and a meticulous review of sometimes obscure historic records, Thompson and his research team at Ohio State University are convinced that the global climate has changed dramatically. full article at Science Daily Quote Link to comment Share on other sites More sharing options...
lastman456 Posted December 29, 2004 Report Share Posted December 29, 2004 Having picked up pieces of petrified trees off the ground in the Libyan Sahara and observed the hundreds of now dry riverbeds in southern Egypt, climactic weather change doesn't seem all that startling. In geology classes it was a well known and often discussed topic. However, these finds seem to suggest that these changes were quite sudden and rather harsh. Since astronomers have long been predicting that there is a large comet that routinely passes very close to earth, which may account for the change in polar positions that happen routinely, perhaps the phenonom are linked. A comet or asteroid passing close enough to earth could affect the magnetic fields which might cause signifigant climate changes. And the good news is that we might live long enough to decide these theories for ourselves. Perhaps this will prove interesting. Quote Link to comment Share on other sites More sharing options...
