Climate change is real. Human beings are contributing to it. It is killing 150,000 people a year. These are poor people in poor countries. They produce far fewer emissions than rich people in rich countries but suffer the worst effects of climate change. This is a class issue, a power issue, a justice issue and a racism issue.
We need to change totally the direction of society to have even a chance of mitigating the worst effects. The upside is that we get to tear down little obstacles like global capitalism in the process.
