Researchers want to genetically modify trees to bind more CO2
Researchers have examined samples from the Arctic and discovered how plants became climate saviors 53 million years ago. Now they want to genetically modify trees so that they can bind more carbon.
Climate change poses major challenges. Today there are large amounts of CO2 and other greenhouse gases in the atmosphere that remain there for several millennia. But almost 53 million years ago, a similarly hot climate prevailed on our planet. So what happened?
Numerous experts worldwide are dealing with this question. Because the findings of that time can possibly also be successfully applied today. A research team has now made a breakthrough in the Arctic mud. They discovered petrified freshwater ferns in a 20 meter thick layer.
Genetically modified trees should bind more CO2
Scientists assume that millions of years ago, giant mats of ferns covered the oceans. These absorbed large amounts of CO2 and stored the greenhouse gas. When the ferns died, they sank to the bottom of the sea. The salt water ensured slow decomposition and thus prevented the release of carbon dioxide.
On this basis the research team wants to develop a tree, which could save our climate. This should grow as quickly as possible and bind significantly more carbon dioxide than other trees. It is also important that the leaves rot slowly.
The first genetically modified patch of forest in the USA
As a result, a small piece of forest was created in February 2023, in which the genetically modified trees are located. The site is the first of its kind in the United States and is designed to show the long-term effects of trees on climate.
Because it is still completely unclear to what extent the trees interact with their environment. The full potential of genetically modified plants has also not been clarified. If the project is successful in the long term, the researchers would like to sell climate certificates to various companies.
