a forest in Staffordshire transformed into a high tech laboratory.

Researchers here are investigating how the trees use carbon, and it's difficult to find out.

In an unusual experiment, extra carbon dioxide is piped to the trees to create the kind of atmospheric conditions expected in the middle of the century, and instruments measure how the forest reacts.

I need to be very, very careful about what that thing effective.

There's still a lot to learn, and he worries.

Governments and companies are rushing to plant trees as an easy answer to climate change.

If you try and use trees to tidy up the mess that we're making front through emissions, you are putting those trees into a very rapidly changing climate on they will struggle to adapt.

This device tracks the movement of carbon dioxide in a healthy forest.

The gas is not only absorbed by the trees, but some is released as well.

What scientists here are finding out is that the way carbon flows into a forest and out of it is a lot more complicated than you might think.

So if mass tree planting is meant to be a solution to tackling climate change.

The trees are gonna have to be monitored and cared for over not just decades, that maybe centuries as well.

Of all the challenges, the task of planting is the simplest.

Shelby Barber from Canada could do an amazing 4000 trees in a day.

People talking about planting millions, billions of trees around the world.

Is it possible, do you think physically, it's definitely possible with the right amount of people there.

A group of people I've personally in three years pointed just over half a 1,000,000 trees.

There are other parts of the forest that a healthy and able to fill in those gaps.

Suddenly, there's momentum to plant trees on a scale never seen before.

So what matters is doing it in a way that ensures the forest thrive.

So they really do help with climate change.

In an unusual experiment, extra carbon dioxide is piped to the trees and instruments measure how the forest reacts.

This device tracks the movement of carbon dioxide.

The trees are gonna have to be monitored on Cared for.
