And that goes for Texas, too, where many are still tempted to shrug and claim, 'This is Texas. It's always been hot.'

Deceleration’s Marisol Cortez speaks with Anel Flores about their new novel Curtains of Rain/Cortinas de Lluvias (Jaded Ibis Press, 2025), a queer coming-of-age story that explores the intersections of homophobia and transphobia with environmental racism in South Texas, specifically the industrial contamination inflicted on Mission, Texas, for decades by companies like Monsanto.

It’s the hottest year ever…again. Heat-related deaths have been spiking year over year. As Deceleration wrote recently, there were nearly 600 heat-related deaths in Texas last year. In Bexar County, 12 local residents died from the heat that same year, according to data released to the Texas Tribune. Border counties have seen hundreds die from the heat since 2010, according to data released to Deceleration. So how are cities respon...

Boca Chica, the “little mouth” of the Rio Grande/ Rio Bravo is increasingly the epicenter of NewSpace new colonizing impulses bridged by an explosion of billion-dollar LNG projects seeking to feed Texas-fracked methane to the world market. It’s here in the lower Texas coast that has so far avoided much of the spoilage of the upper and middle coasts, themselves awash with petrochemical and fossil fuel facilities and all the risk and...

We've heard that this summer has been one of the hottest the Earth has seen since long before official record-keeping began. But policymakers and public health officials too often strain to understand how that heat is impacting people. Medical anthropologist Rose Jones has called the systems of tracking and understanding heat a “train wreck.” Here in dialogue with Deceleration Jones explains why our understanding of heat'...

In the shadow of the port shipping most of all US crude oil to the rest of the world, four 'Clean Slate' candidates are running for local City Council seats.

They also show clearly why they are log...

    Saskia Inwood woke up one morning, knowing her life would never be the same. The night before, she learned the unimaginable – that the husband she knew in the light of day was a different person after dark. This season unpacks Saskia’s discovery of her husband’s secret life and her fight to bring him to justice. Along the way, we expose a crime that is just coming to light. This is also a story about the myth of the “perfect victim:” who gets believed, who gets doubted, and why. We follow Saskia as she works to reclaim her body, her voice, and her life.
