Human releases of carbon dioxide are almost certainly happening faster than any natural carbon release since the beginning of life on Earth.

If we are to save humanity and the planet from the worst mass extinction of all time, worse even than that at the end of the Permian, we must stop at two degrees.

We humans, one species of animal amongst millions, have now become the de facto guardians of the planet's climate stability.

At 1.24 am on 26 April 1986 Chernobyl’s Unit 4 reactor exploded after staff disabled safety systems and performed an ill-advised experiment to check – ironically enough – the reactor’s safety.

You'd be forgiven for thinking that climate change means we'll have to sacrifice our creature comforts. But it doesn't have to be that way.
