Trees and climate change
Scientists at the Smithsonian are using the leaves of one of our favourite trees, Ginkgo biloba to study climate change.
The study involves comparing the fossilised leaves with those collected from living Ginkgo biloba trees.
As Ginkgo trees have been growing for some 260 million years they have adapted to climate change, and this study considers if the number of stoma on the leaves (breathing pores which allow carbon dioxide into the leaves, while releasing oxygen to the atmosphere) has changed as carbon dioxide levels have fluctuated.
