In a report released in July, the Migration Policy Institute offers a comprehensive catalog, by topic, of changes made by the Trump administration to the U.S. immigration system since entering office in January 2017.

The report, “Dismantling and Reconstructing the U.S. Immigration System: A Catalog of Changes under the Trump Presidency,” was written by Sarah Pierce, a Policy Analyst for the U.S. Immigration Policy Program at MPI, and Jessica Bolter, an Associate Policy Analyst with the U.S. Immigration Policy Program at MPI.

Local news station KCCI of Des Moines, Iowa, reports that hundreds of refugee families in eastern Iowa are homeless after a recent derecho.

“Cedar Rapids remains one of the worst-damaged Iowa cities in need of recovery. It’s a need felt especially by refugees and immigrant families,” writes KCCI’s Kayla James in a story posted online.

Local resident Nancy Mwirotsi is leading an effort to help the refugees. Mwirotsi and several others “have made continuous trips from Des Moines to Cedar Rapids. They’ve brought food, clothing and any other supplies they could get,” James reported.

If Joe Biden wins the presidency in November, he is expected to use executive powers to reverse President Trump’s changes related to immigration and refugee policy “and even end some immigration enforcement measures that have been in place for decades,” reports Michelle Hackman in a recent Wall Street Journal article.

“Many of Mr. Biden’s policy plans would require legislation to enact—but immigration is an issue where the former vice president would have the ability to enact much of Democrats’ desired agenda through regulatory changes and other executive actions,” Hackman notes in the story.

Biden has “also said he would pursue a bill providing a pathway to citizenship for the 11 million immigrants in the country who lack permanent legal status, a task made easier if Democrats take back control of the Senate.”

Also, Biden would restore the annual cap on refugees to 125,000 people “from a record-low 18,000, and end a program that sends asylum seekers back across the border to Mexico to await their immigration hearings.”

Migration researchers have found “climate’s subtle fingerprints almost everywhere,” writes Abrahm Lustgarten in a recent article for the New York Times Magazine.

“As the mechanisms of climate migration have come into sharper focus — food scarcity, water scarcity and heat — the latent potential for large-scale movement comes to seem astronomically larger,” writes Lustgarten.

The New York Times Magazine and ProPublica joined with the Pulitzer Center in an effort to model, for the first time, how people will move across borders.

While the model is not definitive, “every one of the scenarios it produces points to a future in which climate change, currently a subtle disrupting influence, becomes a source of major disruption, increasingly driving the displacement of vast populations,” Lustgarten reported.

A worst-case scenario could be “one in which America and the rest of the developed world refuse to welcome migrants but also fail to help them at home. As our model demonstrated, closing borders while stinting on development creates a somewhat counterintuitive population surge even as temperatures rise, trapping more and more people in places that are increasingly unsuited to human life,” writes Lustgarten.
