In April 2024 we announced the (renewed) collaboration between Gigafact and Skeptical Science to create fact briefs, short but credibly sourced summaries that offer “yes/no” answers in response to claims found online. Initially, we published new fact briefs on Saturdays, but switched to Tuesdays earlier this year and while we try to have a new fact brief out each week, we sometimes miss a week due to time constraints and vacations. Regardless of that, we published fact brief #50 - Are humans responsible for climate change? - on September 30, 2025 and thought that this little milestone might make for a good reason to write a short blog post about the current status of this project.
