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.

Unless we decide to reduce greenhouse gas emissions within just a few years from now, our destinies will already be chosen and our path towards hell unalterable as the carbon cycle feedbacks... kick in one after another.

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

If substantial methyl hydrate melt begins to occur in the Arctic Ocean basin, then the (carbon) accelerator will be jammed, and there will be nothing we can do to cut the speed of climate change.

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.

Only by advocating 'politically unrealistic' CO2 concentrations can runaway global warming be avoided. But what is politically realistic for humans is whollymunrelated to what is physically realistic for the planet.

Our evolutionary psychology preconditions us not to respond to threats which can be postponed until later.
