Cloning California’s giant trees to reverse climate change
Volunteers with the nonprofit group Archangel Ancient Tree Archive collect genetic samples from ancient trees and clone them in a lab to be planted in the forest. The group believes the giant sequoias and coastal redwoods are blessed with some of the heartiest genetics of any trees on earth and that propagating them will help reverse climate change.

Brodhagen selects pieces of the cuttings that can grow into clones of the original trees, while Clark plants them in small containers holding a peat-and-gel mixture. The clones will be stored in a climate-controlled laboratory in Copemish until they are large enough to be planted. The group hopes to plant thousands of genetic copies of ancient trees to restore forests and fight climate change. (AP Photo/John Flesher)

The cuttings were taken from an Archangel expedition in California and flown to Michigan, where Brodhagen and Clark snipped off pieces of greenery and planted them in small containers. The goal is to create thousands of giant sequoia clones that will grow large enough to be planted in the wild, helping restore forests and combat climate change. (AP Photo/John Flesher)

The cuttings were taken from giant sequoias in California. Archangel leaders say they’ll keep the tips in the climate-controlled building, where they can grow large enough to plant in the wild, helping restore forests and fight climate change by storing vast amounts of carbon.
