Hello, I'm Prolog. I noticed that you added or changed content in an article, Temperature record of the last 2,000 years, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Prolog (talk) 13:43, 5 January 2023 (UTC)
