The route to avoiding climate change runs from now to 2070. In 50 years’ time, the green revolution must have happened. In 50 years’ time, we must be fossil-free. That’s how simple it is. And yet, so incredibly difficult.

In this book, Samset shows us how we ended up where we are today, explains the models and climate systems we need to grasp, and gives us hope for the road ahead. If we read the expert literature about climate change we’ll find no shortage of material for fire-and-brimstone sermons. But dystopias won’t inspire us to face the future. So this is a climate book that doesn’t deal with worst-case scenarios (although they are mentioned), but focuses instead on offering hope.

We’re taken on a journey to 2070, following one of the routes we can choose to take to avoid the worst consequences of climate change while also building a sustainable world.
