Master has a range of courses which can help you both understand climate change but also use your voice for social justice, leadership and communication.

Some of my personal recommendations on the Masterclass site are:

Jane Goodall

Indra Nooyi

Bill Nye

Roxanne Gay

Noam Chomsky

Free courses by the UN on Climate Change

From Climate Science to Action

Climate Change and Human Rights

For a fee, you can get certifications for completing courses. Especially helpful if you are looking for a professional role in sustainability or climate impact or trying to uplevel your career.
