Stay calm and install heat pumps.
Stay calm and build a Homelab to keep your data at home.
Stay calm and help your neighbours.
Stay calm and read the news but understand your anger on things you cannot change is wasted energy.
Stay calm and care about your direct environment where you can change things.
You are not alone. Many people around you are doing this already.
I am into science and climate activism. I love to learn about social issues and to challenge my own perspectives. I'm also into free and open-source software and I am back in University studying computer science.
