What happens when you stop competing in a zero-sum game and give people a meaningful action to take?

Tom sits down with Tamsin Bishton, the new Head of Communications at Climate Acceptance Studios, to unpack a story of action from her time leading communications at Rewilding Britain.

In 2019 the small team at Rewilding Britain spotted a narrow window of opportunity to influence policy, activate an engaged supporter base and make the connection in the public imagination between nature and climate.

They launched a bold campaign linking land use, carbon capture and nature restoration - grounded in rigorous science, powered by partnership and activated through a UK parliamentary petition.

The results: 100k signatures, a parliamentary debate and wider influence on policy, widespread media coverage, and massive increases in social followers and email subscribers.

In this episode, Tamsin reflects on:

• Why “invisible action” may be more powerful than we think
• The essential need to see climate through a justice lens
• The power of partnerships over competition

What does it take to dismantle climate skepticism in one of the most trusted professions in America?

Tom Clark sits down with Professor Ed Maibach to unpack one of the most remarkable stories in modern climate communication.

16 years ago, US TV weathercasters were split down the middle on human-caused climate change. Today, more than 95% accept the science and they’re reporting on local climate impacts 1,200% more often than before.

In this episode Ed reveals how this transformation happened, exploring:

• Why climate change is fundamentally a public health issue
• The hidden power of “trusted messengers”
• What the tobacco wars teach us about Big Oil today
• Why funding, not evidence, is the biggest barrier
