The list is unreliable because there is no requirement for groups to inform the Subject Adviser when they start up or when they shut down. All the u3a climate groups that I know of as of 14 Sept 2025 are shown on this map. It shows only groups which are listed on the website of the home u3a. A few of these groups are inactive. If you belong to a group which is not shown on the map, or is shown in the wrong location, please email Webmaster.

Another option is to go to the u3a Group Finder Page and search from there.

There is a forum Climate Group Leaders - Facebook where leaders can discuss the practical aspects of running a climate-related group in u3a. You don't have to be a leader to join, you just have to contribute.
