It's the Brian Lairn Show on WNYC.

I'm Amina Serna, a producer for the Brian Lairn show, filling in for Brian today, who is off taking care of a family member who's dealing with a health

issue. Coming up on today's show, we're going to talk about grocery prices. The high cost of

food shopping was a part of Mayor Zora Mamdani's affordability themed campaign. He even proposed a pilot

says will bring prices down, making it easier to build new grocery stores. Plus, for our Health

and Climate Tuesday series, we're going to talk with New York Times Global Health

Reporter, Aborva Mandivili, about how the United States may be about to lose its measles-free

are continuing, right as vaccinations are lagging. And we'll wrap today's show with a question, how cold is it?

If you've been outside today, well, you know it's freezing.

We want to hear your tips too on how to stay warm and safe when the high temperature for today is in the low to mid-20s.

countries until the U.S. has had a deal to acquire Greenland. Trump proposed a 10% tariff starting

February 1st, which he says he will raise to 25% in June if Europe doesn't capitulate. Those countries

are all members of NATO and have said they stand with NATO member Denmark and its autonomous territory, Greenland.

And in multiple social media posts overnight, Trump shared private messages from world leaders,

including one from French President Emmanuel Macron that reads,

I do not understand what you're doing on Greenland.
