First noticed by the brilliant astrophysicist Piers Corbyn, a cyclic cooling has begun which we expect to remove the post-Little Ice Age warming since c.1850, and then a bit ... Renewables will not suffice to keep us all alive and those who don’t care about that will be surprised at who goes first. But the “golden hand” of Free Enterprise and modern techniques can get us through. Bureaucratic management lacks the “can do” spirit of free non-Marxist folk, as has been well-proven.
