NEW YORK — Climate activists are rallying in the streets here and around the world today calling for urgent action curbing carbon emissions, while a controversial but carbon-free nuclear power plant 180 miles away quietly goes offline.

The big picture: It’s an ironic moment in history. Nuclear power provides America — and the world — with one of the largest sources of carbon-free electricity. Many environmentalists nonetheless don’t support it because of fears about safety and radioactivity. Plants are shutting down under economic duress, and in some states and countries carbon emissions are rising as a result.

Driving the news: The protests and the plant.

  • As the social movement to tackle climate change intensifies, the protests today are expected to be among the largest in history
  • The plant shutting down — Pennsylvania’s Three Mile Island — was the site of America’s worst nuclear energy accident after a partial core meltdown in 1979. One reactor shut down because of the disaster, which has since created extra financial hurdles for the remaining reactor.

By the numbers:

  • Nuclear power provides more than half of America’s carbon-free electricity. In Pennsylvania, that share is nearly 94%.
  • It could take Pennsylvania nearly 13 years to replace the lost carbon-free electricity from Three Mile Island, according to a March report by Andrew Place, a commissioner on the Pennsylvania Public Utility Commission.

Facebook boycott organizers share details on their Zuckerberg meeting

Facebook is in the midst of the largest ad boycott in its history, with nearly 1,000 brands having stopped paid advertising in July because they feel Facebook hasn't done enough to remove hate speech from its namesake app and Instagram.

Axios Re:Cap spoke with the boycott's four main organizers, who met on Tuesday with CEO Mark Zuckerberg and other top Facebook executives, to learn why they organized the boycott, what they took from the meeting, and what comes next.

Civil rights leaders blasted Facebook's top executives shortly after speaking with them on Tuesday, saying that the tech giant's leaders "failed to meet the moment" and were "more interested in having a dialogue than producing outcomes."

Why it matters: The likely fallout from the meeting is that the growing boycott of Facebook's advertising platform, which has reached nearly 1000 companies in less than a month, will extend longer than previously anticipated, deepening Facebook's public relations nightmare.

House Minority Whip Steve Scalise’s PAC is inviting lobbyists to attend a four-day “Summer Meeting” at Disney World's Polynesian Village in Florida, all but daring donors to swallow their concern about coronavirus and contribute $10,000 to his leadership PAC.

Why it matters: Scalise appears to be the first House lawmakers to host an in-person destination fundraiser since the severity of pandemic became clear. The invite for the “Summer Meeting” for the Scalise Leadership Fund, obtained by Axios, makes no mention of COVID-19.
