How Climate Has Shifted Over Millions of Years

This short documentary examines how Earth's climate has shifted over the past thirty-four million years, using an unlikely record: a lake in the Russian Arctic. Scientists explain how sediments there preserve clues to the planet's long history of warming and cooling. In just a few minutes, it makes deep climate history clear and tangible. Concise and informative, it is a compact lesson in how our climate has changed. Free to watch in HD on Dr Documentary.
