Campaign and protest have been the traditional tools of environmental action in the UK. American lawyer, James Thornton, set up Client Earth to defend the planet in a different way- by using the courts. Using local laws to challenge governments and businesses they've had success across Europe and beyond, preventing the construction of coal-fired power stations and challenging the curse of air pollution. As well as enforcing environmental laws they're helping get new laws written.

Tom Heap meets James and discusses the carbon implications of his ideas with climate scientist, Dr Tamsin Edwards.

The UK government is betting big on offshore wind to provide a huge percentage of our electricity by 2030. The turbines are certainly efficient, low carbon energy producers but they have one Achilles heel. They're expensive to maintain and repair. Boats or helicopters have to be sent out with a maintenance crew- it's dangerous and costly work. Developers in robotics and artificial intelligence have got together to come up with a solution. If an offshore turbine needs checking an unmanned boat will head out to sea. Once in position it will launch a drone which can inspect the turbine. If a closer look is needed then the drone can launch its secret weapon- the BladeBUG. It's a suitcase-sized robot which can cling to the huge turbine blades, check them and even clean or repair them. They should make new offshore wind development cheaper and safer.

Tom Heap meets the experts behind the robots - BladeBUG CEO Chris Cieslak; Professor Sara Bernardini from Royal Holloway, University of London - and works out the carbon impact of offshore wind expansion with climate scientist, Tamsin Edwards of King's College London.

Around the world many girls leave school before completing their education. It's said that those who stay to the end of high school have more agency and choice, but also earn more money and have fewer and healthier children.

Tom Heap hears how education and access to family planning don't just impact family size, they can also propel young women into positions of leadership where they can help their communities adjust to climate change.

Dr Tamsin Edwards of King's College, London helps Tom calculate just how useful secondary education for girls can be in the fight against climate change.

Simple and sublime seagrass meadows work naturally to absorb carbon. The leaves cause friction in the water and trap carbon from organic matter in the sediment. Yet industrial activity and pollution has damaged and reduced the extent of the meadows around the UK coast. With the marine environment improving, work is being done to restore patchy seabeds and create new ones, both in the UK and around the world. Take a dip with Tom Heap as he explores the wonders and potential of these plants on the sea floor.

Back in the studio Dr Tamsin Edwards of King's College, London helps Tom calculate just how useful seagrass can be in the fight against climate change.

BBC Radio Four presents 39 ideas to relieve the stress that climate change is exerting on the planet.

Trees soak up carbon dioxide, trees store carbon dioxide. So why not build with wood instead of concrete and steel? The usual reason is strength, but Dr Michael Ramage at Cambridge University has what he thinks is the answer- cross-laminated timber. It's strong enough to build a skyscraper and replaces lots of that carbon from conventional building. Tom Heap and Dr Tamsin Edwards take a look at the global possibilities of cities built of wood.

We’re resourceful, adaptable and the smartest thing this planet has ever seen. We got ourselves into this mess but we can get ourselves out of it. BBC Radio Four, in partnership with the Royal Geographical Society presents 39 ideas to relieve the stress that climate change is exerting on the planet.

From tiny solar cells to the total transformation of the Siberian landscape, Tom Heap and Dr Tamsin Edwards from Kings College, London view the fundamental problem of our age from a fresh perspective. Small things that make a big difference. Big things that make a small difference. We’re going to need every one of them.
