Ancient tree stumps found under glaciers in Southeast Iceland are confirmed to be roughly 3,000 years old, RUV reports. A specialist believes the remarkably well-preserved stumps were part of a massive forest that disappeared after a long period of a warm climate. It is believed that 3,000 years ago, the forests were much larger, even reaching the highlands. Approximately 500 BC, the climate became colder, and glaciers began to
form, destroying parts of the forests.
The planet has been here billions of years, with mankind only having been here for the last million or so. In that time, the planet has changed climates several times.
