We do need action on all levels of society, and we need to be treating this as a crisis.
On a local level (in the UK) there are a lot more community and Council groups being setup to try and find solutions I would absolutely recommend attending those.
Other than that, ensure your pension is invested in green and eco investments and try to fly less (maybe even drive less).
Christ. We need massive, global action. We need people in the west to commit to drastically lowering their carbon footprints, ideally by finding alternatives to gas powered cars and cars in general, and we need immediate action on geo-engineering. Atmospheric cloud dust, carbon capture, everything. We can’t debate the ethics and morals forever. We just desperately need to start acting.
Yes, the time for debate and discussion are over. We just need people doing things and trying things on mass scale. I would highly recommend writing to your local representatives and ensuring they know it’s an issue people do care about. We need change from the bottom up and top down.
