An interesting report from Daily Tech today about Lake Baikal in Siberia.
Lake Baikal is the deepest lake in the world (about a mile) and is the largest freshwater lake in the world by volume.
Due to it's depth and distance from the ocean, the article says Lake Baikal has "the northern hemisphere's most pristine, uninterrupted sedimentary record."
Researchers found something interesting in studying that record, as it relates to the current global warming controversy:
The record clearly demonstrates the region has often been considerably warmer than it is at present. More stunning is the most recent data, which shows Siberia first began warming around 250 years ago -- long before the industrial revolution, and its resultant greenhouse gas emissions.
Just as the dinosaurs didn't have SUVs, I don't think they had them 250 years ago, either. Maybe it's not SUVs, but that big ole star in the middle of our solar system that's behind any heat increases?
