Last Friday's report from the United Nations confirms the huge danger from our continued dependence on fossil fuel. But one simple thing can break this dependence. It needs to be cheaper to produce non-carbon energy than it is by digging up coal, gas or oil. Once this happens, most of the coal, gas and oil will automatically be left undisturbed in the ground.

To make non-carbon energy become competitive is a major scientific challenge, not unlike the challenge of developing the atom bomb or sending a man to the moon. Science rose to those challenges because a clear goal and timetable were set and enough public money was provided for the research. These programmes had high political profile and public visibility. They attracted many of the best minds of the age.

The issue of climate change and energy is even more important and it needs the same treatment. In most countries, there is at present too little public spending on non-carbon energy research. Instead, we need a major international research effort, with a clear goal and a clear timetable.
