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

Once the 'portals of the future close - in Amazonia, Siberia or the Arctic - we will find ourselves powerless to affect the outcome of this dreadful tale.

Silent Summer - a never-ending heat wave, devoid of birdsong, insect hum, and all the weird and wonderful living noises that subconsciously keep us company.

This is like playing Russian roulette with a Luger rather than a revolver. One bullet, one chamber - and we're pulling the trigger.

We no longer need to discuss whether or not it is safe – over a decade and a half with three trillion GM meals eaten there has never been a single substantiated case of harm. You are more likely to get hit by an asteroid than to get hurt by GM food.

Conventional economic theory... counts the depletion of resources as the accumulation of wealth.

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.
