Shortly after the Union won the Civil War in 1865, a union major general issued an order: “The people of Texas are informed that, in accordance with a proclamation from the Executive of the United States, all slaves are free.” June 19, known as Juneteenth, has long been celebrated by African Americans. But in 2020, in the thick of the Covid-19 pandemic and the protests that followed the murder of George Floyd, Juneteenth took the internet by storm. Marketplace’s Lily Jamali spoke with Brandon Ogbunu, professor in the Department of Ecology and Evolutionary Biology at Yale, who wrote about that moment for WIRED back then. He revisited what was happening at that time a year before Juneteenth became a national holiday.

She attended the Worldwide Developers Conference in Cupertino, California, this week as Apple execs talked through the company’s entry into the AI race.

 

Back in 2020, Microsoft made an ambitious pledge to go carbon negative by 2030. But that plan is encountering some headwinds, according to its latest sustainability report. It showed Microsoft’s carbon emissions have increased by 30% since it made that pledge four years ago and comes a reminder of the significant environmental cost of the AI boom. Just how significant? Marketplace’s Meghan McCarty Carino asked Emma Strubell, a computer science professor at Carnegie Mellon University who co-wrote a paper about the specific energy demands for common uses of this technology.

President Joe Biden and former President Donald Trump have been courting Latinos this election season. Relatedly, perhaps, this voting bloc has emerged as a target for disinformation.
