Even after a summer of drought, fires, and extreme weather, governments seem no more inclined to address the enormous dangers of global warming than before. Within parts of the left, pessimism reigns about what it might take, not just politically but technically and socially, to halt climate change. For some, nuclear power seems a necessity; for others, reducing our standard of living is the solution. Left environmental writer Gar Lipow argues against both. He suggests that while renewables could replace our current energy needs, the best way to halt global warming is by fighting for social justice and class power.
