I am so incredibly thrilled to say that my book is coming out in January!

Shelter from the Storm is a deep, sprawling overview of the ways that climate change is creating a new era of human migration

For the first time in about 70 years, net immigration to America could be zero. Beneath the noise of tariff and budget fights, migration may well be the biggest economic story of 2025.

My latest for @economist.com: Welcome to Zero Migration America

"the effort in Washington shows how migrants stopped by local law enforcement for low-level infractions can swiftly be detained by ICE — a boost for an agency struggling to meet the White House’s demands for higher arrest numbers."

ICE had made only 85 arrests in Washington from Jan. 20 through the end of July. But from early August until mid-September, ICE made around 1,200 arrests, according to officials with knowledge of the data.

We detail how that happened:

"While many of those detained have immediately declared their U.S. citizenship to officers, they have routinely been ignored.." In some cases citizens were handcuffed and held in detention overnight

As immigration agents have escalated their tactics, US citizens, many of them Latino men, have been stopped and in some cases taken into custody by law enforcement officers. Allison, Jenny and I took a closer look at the encounters. www.nytimes.com/2025/09/29/u...

Very smart and kind people whom I respect very much called Shelter from the Storm "troubling and powerful," "forceful and vivid," "with masterful storytelling and insightful explanations."

"A must read for everyone concerned with climate change and migration."

But the book isn't sensationalist

People have always moved for all sorts of reasons, and will continue to do so. What's new about climate change is not that people are moving, but that many are doing so in a harried, haphazard manner for which our legal systems are entirely unprepared

I've been working on the book for several years. It's got reporting from multiple continents, including drought-stricken Guatemalan coffee farmers & Bangladeshi families whose houses were wiped out by cyclones

Many have already begun to move somewhere more accommodating

🚨NEW: For the first time in history, the single largest group of people arrested in the interior and sent to ICE detention is people with NO criminal record.

As of yesterday's data release, 40%(!) of those arrested in the interior and detained by ICE had no prior conviction or pending charges.
Chart shows Detention Population, Among Those Arrested by ICE in the Interior, by Criminal Record. The chart shows three lines; Prior conviction, pending criminal charges, and no criminal record. From 2019 through September 2025, the largest group is people with criminal convictions, with much further down people with pending charges. But starting in January, those without criminal records spikes dramatically. In July it crossed pending charges and in the latest data it jumps above criminal convictions.

EXCLUSIVE: A new analysis by The Xylom's @alexip718.com shows for the first time just how much America’s top research institutions have grown to depend on H-1B skilled workers — and how this delicate balance might be disrupted by U.S. President Donald Trump’s crackdown on legal immigration.

one reason these courthouse arrests/confrontations are so common now is bc authorities do administrative two-steps to toss out ongoing deportation cases (which take a long time) & deport people thru fast-track expedited removals (which can take a couple hours)

The costly failure of the CBP Home self-deportation app

According to an NBC News analysis, in the five weeks following its implementation, only 356 people used it to voluntarily leave the country, and no further data has been published since then

President Trump channels Jerry Seinfeld in bizarre, way-late post.

"Some neighborhoods will retreat and others will be protected, and still others – often lower-income communities – may be left behind."

This is, in essence, the story of climate migration worldwide at every scale: Some people get new seawalls, other people move, and the worst off get stuck in place

40% of shadow docket cases under Trump have been about immigration

A significant factor for everything that has happened the last 9 months
kathleenbush.bsky.social
That makes 10 SCOTUS orders on immigration from the emergency docket under Trump 2.0, out of 25 orders total, per @stevevladeck.bsky.social 's chart

(birthright citizenship consolidated 3 cases, btw)

Here's my updated chart of #SCOTUS's rulings to date on emergency applications from the Trump administration.

Even before the start of President Trump's surge, D.C. had the most police per-capita of any U.S. city. By a quite a bit.

And that's just counting the city's force, not the huge array of other police agencies here. The Capitol Police, also in D.C., is bigger than Baltimore's police department.

Bowser starts with talking about MPD's staffing, currently at 3,200. "We have a lot of room to grow our department," she says. Her goal is to get to 4,000 eventually. "We need to add hundreds more police." There are 135 recruits this year, she says.
