I was just researching ''Cli-fi'' and must say I love your site! Thank you!
I will spread the word for sure.
IECA, International Environmental Communication Association is a good resource for you and your collaborators worldwide.
I think there are many network opportunities for you and others working on these issues.
Full disclosure: I am on the board, and we love getting in touch with new people from all walks
of life who care about eco issues and communication!
