Human composting offers an environmentally friendly end. Some are pushing to legalize it in Illinois. This green approach avoids the release of smoke from cremation and the leaking of fluids from burying embalmed bodies.

At one time, Illinois was a top oil producer. Today, that legacy is a $160M problem. Abandoned oil and gas wells pose environmental and public health risks. For three decades, the state has mismanaged funds earmarked for minimizing the threat.

A snowy, cold start to winter follows a very warm fall. How are Illinois seasons changing? In Chicago, fall is the second fastest-warming season after winter, and outliers, like this week’s cold, don’t lessen the impact of climate change, experts say.

Chicago just had its snowiest start to the season since 1978. But predicting how much snow it'll get over the next few months can be tricky. Here's what's happening to seasons in Illinois — including increasingly warming falls, like the one we just had. For @chicagotribune.com:

Illinois lawmakers urged to ‘step up’ and ‘fight like hell’ as EPA moves to cut wetlands protections New U.S. EPA rule would strip protections from 72% of the state’s remaining wetlands, which play a crucial role in mitigating flooding and filtering drinking water.

I'm in the @chicagotribune.com today calling on @govpritzker.illinois.gov to protect the Illinois wetlands that keep floods out of our basements & our water clean.

EPA's new rule would strip the vast majority of Illinois wetlands of Clean Water Act protections.

Muskrats fight invasive cattails and help restore biodiversity in Great Lakes wetlands, Loyola study finds Dam-building beavers are known for changing their ecosystems; muskrats can substantially alter vegetation structure.

"In areas densely packed with tall cattails," @adrianaperez.bsky.social reports, "muskrats create a 'patchwork' of small openings that allow plants of different heights to grow. That, in turn, creates habitat for diverse native wildlife."

Roughly 20 bystanders and passersby started following the officers through downtown Chicago, chanting “ICE, go home!”

The crowd of protesters around them grew bigger, yelling “shame.”

Reportedly some ICE detainees are held for days, even up to a week. Our room stank of sweat & pepper ball powder after just a few hours. Their room appeared dirty, filled with men dressed for labor, trying to get comfortable to sleep in chairs or on the cold floor in the cinder block room.

I saw one man sitting in the room who had gauze wrapped around his head like he had a serious head wound. The room looked uncomfortably full at half "capacity." Keep in mind, this is seating capacity. Imagine a conference room with max capacity 80, and then holding people in there for days.

Their rooms were maybe 30x30. Each room was marked with a sign reading "Capacity: 83" (I think, it was low 80s). There were roughly 40 men in one room, with an open bathroom area to the side. It was harder to get a look at the women's holding room, but looked like 10-12 women.

Yes, arresting a journalist for doing their job is a big flashing red light. But I don't want people to forget the whole reason everyone is out there.

This is what I saw inside:

Four holding rooms. Two smaller rooms were being used for holding protesters. Two larger rooms held ICE/CBP captives.

I’m out, I'm sore. I'll have more later, but right now I have to say a couple of things. First, walking out of there to learn about the kindness, support, and quick action from so many of you all has meant the world to me, my wife, and co-founder, Raven. Thank you.
