If you're feeling anxious or depressed about the climate and want to do something to help right now, from your bed, for free...
Start helping with citizen science projects
What's a citizen science project? Basically, it's crowdsourced science. In this case, crowdsourced climate science, that you can help with!
You don't need qualifications or any training besides the slideshow at the start of a project. There are a lot of things that humans can do way better than machines can, even with only minimal training, that are vital to science - especially digitizing records and building searchable databases
Those are all on one of the most prominent citizen science platforms, called Zooniverse, but there are a ton of others, too.
Oh, and btw, you don't have to worry about messing up, because several people see each image. Studies show that if you pool the opinions of however many regular people (different by field), it matches the accuracy rate of a trained scientist in the field.
I spent a lot of time doing this when I was really badly injured and housebound, and it was so good for me to be able to HELP and DO SOMETHING, even when I was in too much pain to leave my bed. So if you are chronically ill/disabled/for whatever reason can't participate or volunteer for things in person, I highly highly recommend.
Next time you wish you could do something - anything - to help
Remember that actually, you can. And help with some science.
