Climate politics remains overwhelmingly dominated by NGOs, journalists and scientists, observes Matt Huber in his recent Climate Change as Class War. Huber, a geography academic involved with the Democratic Socialists of America, insists that the "the climate struggle is about power" – meaning both class relations and energy. The book aims to counter the "professional middle class" politics that occupy the environmental left through a political strategy based on workers' material interests and fought through trade union struggle.
