Siberia’s Lake Baikal is the world’s deepest lake. It contains more water than all five of North America’s Great Lakes combined.
Fed by over 300 rivers and far from the moderating effects of any ocean, it offers a pristine, uninterrupted sedimentary record that permits a highly accurate reconstruction of temperatures over a broad area.

Moreover, the recent warming trend began about 250 years ago—long before the Industrial Revolution and the resulting increase in greenhouse gases.
