Amid all the cheering over the landmark climate agreement in Paris this weekend, there were also criticisms that it did not go far enough, including from many environmental advocates who had been working for years to push climate change onto the world’s stage and inspire collective action.

At least by one measure — helping to raise the profile of climate change as an urgent problem — those advocates have succeeded. And so what’s next for them?

Bill McKibben, co-founder of the climate activism group 350.org, posted photo after photo from Paris from his Twitter account celebrating the marches and protests after the deal, and wrote: “This agreement won’t save the planet. It may have saved the chance to save the planet (if we all fight like hell in the years ahead).”

In an interview via email, Mr. McKibben said that the environmental movement would be supportive of the Paris plan, but would expect to see results. “We’ll take them at their word, at least for now, and ask them to prove it,” he said.
