for one thing, get more people to raddle because whenever I post the alarming news / science to reddit, it gets mass downvoted and I even get people accusing me of doomsdaying. Liberals will always stand in the way of action.

Control by oligarchs, he argues, thwarts rational decision-making, because the short-term interests of the elite are radically different to the long-term interests of society. This explains why past civilisations have collapsed “despite possessing the cultural and technological know-how needed to resolve their crises”. Economic elites, which benefit from social dysfunction, block the necessary solutions.

The oligarchic control of wealth, politics, media and public discourse explains the comprehensive institutional failure now pushing us towards disaster. Think of Donald Trump and his cabinet of multi-millionaires; the influence of the Koch brothers in funding rightwing organisations; the Murdoch empire and its massive contribution to climate science denial; or the oil and motor companies whose lobbying prevents a faster shift to new technologies.

Public figures talk and act as if environmental change will be linear and gradual. But the Earth’s systems are highly complex, and complex systems do not respond to pressure in linear ways. When these systems interact (because the world’s atmosphere, oceans, land surface and lifeforms do not sit placidly within the boxes that make study more convenient), their reactions to change become highly unpredictable. Small perturbations can ramify wildly. Tipping points are likely to remain invisible until we have passed them. We could see changes of state so abrupt and profound that no continuity can be safely assumed.

Only one of the many life support systems on which we depend – soils, aquifers, rainfall, ice, the pattern of winds and currents, pollinators, biological abundance and diversity – need fail for everything to slide. For example, when Arctic sea ice melts beyond a certain point, the positive feedbacks this triggers (such as darker water absorbing more heat, melting permafrost releasing methane, shifts in the polar vortex) could render runaway climate breakdown unstoppable. When the Younger Dryas period ended 11,600 years ago, temperatures rose 10C within a decade.
