During the age of dinosaurs, a family of plants known as cycads flourished all around the planet. These fern-like species left fossils everywhere from Alaska to Antarctica, but their descendents have been restricted to tropical and subtropical habitats as Earth’s temperatures cooled.

Now, in an age of human-driven global heating, fertile cycads are returning to one of their old haunts. For the first time in an estimated 60 million years, cycads have produced both male and female cones on the British Isles. It would be purely amazing, if it wasn't the direct result of the very same climate trends that are threatening to displace tens of millions of people due to rising sea levels.
