Finally, finding high-profile advocates and allies — including in government — can help funders push change ahead. Barbados Prime Minister Mia Mottley, an outspoken advocate for building climate change resilience, lambasted world leaders at last year’s United Nations Climate Change conference of the Parties in Glasgow, Scotland, for doing too little to cut emissions and help communities adapt to surging threats.

“When will we, as world leaders, address the pressing issues that are truly causing our people angst and worry?” Mottley demanded. “Are we so blinded and hardened we can no longer appreciate the cries of humanity?”

Rihanna, who Mottley declared a Barbados national hero last year, has used her international profile and hefty social media following — more than 100 million followers on Twitter and 130 million on Instagram — to help open doors and push for change.

Effective climate action “doesn’t have to be innovative technology solutions,” Lucas said. She hopes more funders looking for ways to drive action on climate change will, like Rihanna’s foundation, think about backing communities and justice movements.
