In celebration of Earth Day, we are wishing "happy birthday" to the world's oldest trees. There is a tree living in a secret location in California which is 5,000 years old. Now scientists have discovered a group of pine trees in Sweden which are 8,000 years old?probably the world's oldest living trees!
Niklas Pollard quotes researcher Lars Hedlund as saying, "These were the first woods that grew after the Ice Age. That means that when you speak of climate change today, you can in these (trees) see pretty much every single climate change that has occurred."
If you want to learn the secrets of the past, then William Henry is the Dreamland host for you! (And he can also tell you what's likely to happen in the future).
