Climate change is already affecting millions of people. Governments talk about taking action to limit global heating to 2 degrees Celsius above pre-industrial levels, but the greenhouse gas emissions allowed by their policies have the Earth on track to heating far more than that by the end of the century - a level of heating that will have truly disastrous consequences. Refusing to despair, David Camfield argues that even a ravaged planet is worth fighting for - and that ultimately the only solution to the ecological crisis created by capitalism is a transition to ecosocialism.
