Accurate and neutral information about climate change or other contentious topics can help us make informed decisions and make the topic less polarised. Also, people are wrong on the internet. I'm passionate about making Wikipedia articles easier to understand, as us experts like to correct people that are wrong on the internet with fancy words.
I support User:TatjanaBaleta, who works as a Wikimedia Visiting Fellow at the University of Exeter, as part of my job. I will generally not edit directly for this project, but will be organising a edit-a-thon as part of the module I teach, and may improve edits from students.
I started editing on the Dutch Wikipedia in 2013, mostly articles on physics, climate change and women in science (User page). Around 2018 I became active here, working on climate change and energy articles. As a picture can say more than a thousand words, I've dedicated some time to improving climate change graphs. I started an cross-language effort get climate denial removed after a BBC journalist found widespread misinformation.
Quick and ugly check to see if your writing is too difficult: The Hemingway App. A readability score (Flesch Kincaid Reading Ease) over >45 is fairly okay. Another rule of thumb: 4S: short words, short sentences, short paragraphs, short articles.
