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.

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

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