The extreme weather events of the summer of 2018 are not just symptoms of climate breakdown. They are early stage warnings of a protracted process of civilisational collapse as industrial societies face some of the opening symptoms of having already breached the limits of a safe climate. These events are a taste of things to come on a business-as-usual trajectory. They elicit a sense of how industrial civilisational systems are vulnerable to collapse due to escalating climate impacts. And they highlight the urgent necessity of communities everywhere undertaking steps to achieve a systemic civilisational transition toward post-capitalist systems which can survive and prosper after fossil fuels.
