Unless we move to net-zero carbon by 2030 the future of our planet is uncertain. Labour has appreciated that and set 2030 as its net-zero carbon target date. Not so the Tories. As the Guardian has just reported of Andrea Leadsom's just delivered Tory conference speech:
In a great many ways this is good news: the choice as to whether we are to survive on this planet, or not, is now on the political agenda. The Tory option is extinction. Young people will know what they have to do.
That's Cummings getting things seriously wrong.
