A Twitter bot that updates your Twitter bio/location with weekly atmospheric CO2 levels.

To use this Twitter bot you'll need a Twitter developer account. Apply for one here: https://developer.twitter.com/en/apply-for-access

Hint: If you tell Twitter that you only want to use the API for educational purposes, you'll usually get access without further questions 🤫

Then you will need to create a new app and set the app Permissions to Read and Write. You will need the following keys:
consumer key, consumer key secret, access token key and access token secret (consumer keys may also be labeled as API key)

You'll have to save them into GitHub Actions Secrets with the following names:

• CONSUMER_KEY
• CONSUMER_KEY_SECRET
• ACCESS_TOKEN_KEY
• ACCESS_TOKEN_SECRET

Then you have to create another secret called DESCRIPTION with your desired Twitter bio/location prefix. It should end with something like "current co2 level:" as the current atmospheric CO2 level will be appended at the end.

For example my bio template looks like this: "/dev/null | climate activist @FridayForFuture | born at 379ppm – currently"

If you want to use the location field of your Twitter profile instead of the description, you can set the secret TARGET to location (it defaults to description so you don't have to worry about setting it when you are using it with the description) Then the the current atmospheric CO2 level will be appended to the set DESCRIPTION and saved in the location field.

Fun fact: the Twitter location field has a client side max of 30 chars but with the API you can set up to 150 chars. 🤯 This means that you can set up to 139 chars as your location prefix.

Note: you don't need to append a space to the end of the DESCRIPTION secret, as the bot does this for you automatically

That's it! 🎉 Now every day at 1 am your Twitter bio/location should update with the current atmospheric CO2 level informing other people about climate change 🔥
