It is a very welcome development that @GretaThunberg used the launch of her new book in October to place responsibility for the climate crisis at the door of capitalism and to call for its overthrow.
Greta said that capitalism is "an extreme system built on the exploitation of people and the planet. It is a system defined by colonialism, imperialism and oppression and genocide."
Greta Thunberg's journey from school striker and climate campaigner to support for the anticapitalist left is a journey that can be, and hopefully will be, undertaken by many others in Generation Z.
A massive programme of public investment in green energy is necessary so that fossil fuels can be left in the ground. But such a programme could create tens of millions of well-paid unionised jobs worldwide too #GreenNewDeal
A #FourDayWorkingWeek would raise hourly wage rates and create more leisure time for workers while significantly reducing energy consumption.
Massive wealth taxes could fund free transport, a four-day work week and green jobs. But at the same time, such taxes would reduce the number of private jets, private swimming pools, McMansions and other luxury goods that are deeply injurious to the environment.
The capitalist establishment would fight to the bitter end to prevent such a programme from being implemented, however. Capitalist opposition could only be overcome by destroying its power based in the economy and the state machine.
No trust in this system!
That means the nationalisation of the big corporations and financial institutions, seizure of billionaire wealth, the sacking of the top brass of the military, the police, the judiciary and the civil service with the creation of a new state..
Democratically controlled from below by ordinary, working-people.
This is the outline of a democratic socialist society which would put the environment before profit.
#COP27 took place in Egypt as the climate crisis worsens. In October, the World Meteorological Organisation (WMO) reported that there are now record levels of all three greenhouse gases (carbon dioxide, nitrous oxide, methane) in the atmosphere.
Last year saw the biggest year-on-year jump in methane concentration in 40 years. The growth rate for carbon dioxide concentration was greater last year than the average over the last decade.
