Oak trees accumulate more wood when there is more carbon dioxide (CO₂) in the atmosphere. That’s the key finding from our new study, carried out in a long-established forest in Staffordshire, England, that we have turned into a huge field experiment by injecting with extra CO₂. After we increased CO₂ levels to what will be the planetary level in the 2050s, trees took more of it from the atmosphere and their wood production increased by 10%.

In some ways, this result is reassuring. We know that more CO₂…
