Climate change deniers are spreading disinformation through social media. And it only takes a single viral tweet to slow down the action needed to stop our planet from heating up.

Guests: Harriet Kingaby Co-chair at The Conscious Advertising Network Susan Murcott Environmental Engineer and Lecturer
