Earth keeps getting hotter. And despite some efforts to slow planet-warming greenhouse gas emissions, they're still rising, leaving a lot of people hungry for alternative climate solutions. One idea: reflect sunlight away from Earth. Amy Scott, host of the Marketplace climate podcast, “How We Survive,” looked into one out-there proposal to do just that, and whether it could one day become a reality.

File this under the definition of irony: last month, The New York Times reported that a high-profile new book, "The Future of Truth: How AI reshapes reality," includes several quotes that appear to be made up or misattributed. Author Steven Rosenbaum acknowledged he'd used AI in the writing process.

One of the quotes came, allegedly, from a book by data journalist and NYU professor Meredith Broussard. It was a critique of trusting algorithms to make decisions in medicine.

Here at “Marketplace Tech,” we have an unexpected connection to this story. We called up Broussard to discuss it.

Enforcement of the Take It Down Act began last month. If tech firms don’t comply and take down non-consensual intimate images — AI-generated or not — within 48 hours of being notified, they face financial and criminal penalties.

SpaceX is targeting a $1.77 trillion valuation, but some analysts think it's worth half that. Plus, Florida sues OpenAI — the first state to take legal action against an AI company.

But first, President Donald Trump signed an executive order this week, similar to the one he called off last month, asking AI companies to give the government a first look at advanced models that could have national security implications. It comes after models like Anthropic's Mythos have raised cybersecurity concerns for reportedly being too good at finding and exploiting software vulnerabilities.

When a store offers different shoppers different prices depending on factors like the weather, the time of day, and what the store knows about each buyer, it’s called dynamic pricing.

This spring, Maryland, became the first state to ban this practice in grocery stores. The state’s governor Wes Moore proposed the law.

Marketplace’s Stephanie Hughes spoke with Gov. Moore at the statehouse in Annapolis about why he wanted this ban, his administration’s plans to train the state’s workforce for a future AI economy, and more.
