With a Biden administration set to take over in January, one arena for policy whiplash is the environment.

The president-elect has promised to rejoin the Paris Agreement against global warming on the day he's sworn in, and campaigned on the existential threat that is climate change. What does that mean for Grist, a news non-profit focused on environmental issues, and which has experienced a "Trump bump" just like many news organizations covering the White House over the past four years.

"I think sometimes people give when they're excited about good things too," Grist CEO Brady Piñero Walkinshaw said on the Digiday Podcast. "And folks are excited about good things [on environmental policy], not just attacks or assaults" on it.

Grist's staff of 50 depends on around 5,000 "low-dollar members," Walkinshaw said. Five percent of the company's six to seven million dollar budget comes from advertising, but the majority is via partnerships with foundations. "The climate is increasingly one of the top-of-mind issues to a growing, growing, growing number of Americans," Walkinshaw said.
