Speaker Series

The Speaker Series enables us to grapple with the ongoing consequences of political inaction and to raise necessary considerations in the year leading up to the Climate Change Education Summit and Action Plan.

Invited speakers offer provocations and considerations and they share their own perspectives regarding the challenges of climate change education.

To participate, register your interest in the Connect tab of this website and we will share the details of each speaker event. You will need to register for each speaker – see list below.

Our diverse and exciting range of speakers will grow throughout the year. Return here regularly to see who is up next!

We will record these webinars and they will be available on our site right after the event.
