I would also recommend the Climate Reality Project, they have speakers all over the globe that can come and give presentations: https://realityhub.climaterealityproject.org/registration

Hey Videli! We can come actually! If you can introduce us to a contact person in your university and school, we can take it from there. We deliver climate education workshops. During three hours and working in small groups, participants proceed through several rounds learning about the causes and effects of climate change. It’s a highly interactive, engaging and thought-provoking workshop, designed to foster collaboration and teamwork and to bridge a gap in making climate science more accessible to citizens around the world, no matter the background. It's called Climate Collage and it has been played by more than 166.000 people around the world. Please feel free to reach out with any questions or thoughts: hello@weneedyoutoo.com
