It was midday on a Saturday, and Simonetta led me from the open front door of her home in southeast Chicago to her sitting room and settled next to her husband, Christopher, on the couch. In the 1980s, Christopher had worked a few blocks away at U.S. Steel South Works, earning three times the minimum wage with a high school diploma – more than enough to buy a house near Simonetta’s parents before their first baby arrived. Like their neighbors in southeast Chicago, Simonetta and Christopher’s expectations for work and home were set by the steel industry. Between 1875 and 1990, the employment offered here by eight steel mills created a dense network of working-class neighborhoods on the marshlands 15 miles south of downtown Chicago. For the tens of thousands of employees who lived and worked in this region, steel was a rare breed of work: unionized, blue-collar jobs that paid middle-class wages, with starting salaries in the 1960s at nearly three times the minim...

Modern buildings tend to take electricity and air conditioning for granted. They often have glass facades and windows that can’t be opened. And when the power goes out for days in the middle of a heat wave, as the Houston area experienced in July 2024 after Hurricane Beryl, these buildings can become unbearable. Yet, for millennia, civilizations knew how to shelter humans in hot and dry climates. As an architectural designer and researcher studying urban resilience, I have examined many of the techniques and the lessons these ancient civilizations can offer for living in hotter and drier conditions. With global temperatures rising, studies show that dangerously hot summers like those in 2023 and 2024 will become increasingly common, and intense storms might result in more power outages. To prepare for an even hotter future, designers today could learn from the past. Sumerians: Keeping cool together The Sumerians lived about 6,000 years ago in a hot and dry climate that...

The North Atlantic Ocean has been running a fever for months, with surface temperatures at or near record highs. But cooling along the equator in both the Atlantic and eastern Pacific may finally be starting to bring some relief, particularly for vulnerable coral reef ecosystems. This cooling comes from two climate phenomena with similar names: La Niña, which forms in the tropical Pacific, and the less well-known Atlantic Niña. Both can affect the Atlantic hurricane season. While La Niña tends to bring conditions ideal for Atlantic hurricanes, the less powerful Atlantic Niña has the potential to reduce some of the hurricane risk. Cooling in the tropical Atlantic along the equator is a sign an Atlantic Niña may be forming. NOAA Climate.gov We’re ocean and atmospheric scientists who study this type of climate phenomenon. It’s rare to see both Niñas at the same...

Climate change has been in the news for more than 40 years. It’s typically covered as a scientific or political issue. However, social scientists like me have found that feelings and values are what drive people toward broad, collective change – not charts, graphs or images. Surveys confirm that the majority of Americans now believe that climate change is real. But many adults seem to feel too exhausted, defeated or powerless to do anything about it. I am leading a large multiyear research project funded by the National Science Foundation that examines how to tap into morals, ethics and spirituality to create enduring behavioral shifts on this issue. In the pilot study for this project, which has not been published yet, we recently surveyed 275 U.S. adults to understand their relationship with and feelings toward the natural world. This is a first step toward understanding how to start communicating differently about climate change. Climate change is altering weat...

My favorite place in the world isn’t a fixed location. It’s the JOIDES Resolution, an internationally funded research ship that has spent its service life constantly on the move, from deep in the Antarctic to high in the Arctic. Since 1985, scientific expeditions on this one-of-a-kind oceangoing laboratory have drilled 230 miles (370 kilometers) of sediment and rock cores – long cylindrical samples that provide a unique view of the ocean floor. The cores come from a thousand different locations, enabling scientists from many universities around the world to explore changes within the Earth. They also provide a window into our planet’s history. The ocean floor preserves a geological library that documents millions of years of climate change and evolution. The JOIDES Resolution leaves Honolulu in 2009. IODP/Wikipedia, CC BY Sadly, the JOIDES Resolution, also known as the JR...

When the World Health Organization declared COVID-19 a pandemic on March 11, 2020, humans had been the only species with reported cases of the disease. While early genetic analyses pointed to horseshoe bats as the evolutionary hosts of SARS-CoV-2, the virus that causes COVID-19, no reports had yet surfaced indicating it could be transmitted from humans to other animal species. Less than two weeks later, a report from Belgium marked the first infection in a domestic cat – presumably by its owner. Summer 2020 saw news of COVID-19 outbreaks and subsequent cullings in mink farms across Europe and fears of similar calls for culling in North America. Humans and other animals on and around mink farms tested positive, raising questions about the potential for a secondary wildlife reservoir of COVID-19. That is, the virus could infect and establish a transmission cycle in a different species than the one in which it originated. Researchers have documented this phenomenon of human-...

“Hey Rupam, open the door. Take this fish,” a woman yelled from outside. I was sitting in the kitchen at my friend Rupam’s house in rural northeast India. It was the heart of monsoon season, and rain had been falling since morning. The woman must have been shouting because the noise of the rain on the tin roof muted everything else. The aunty who lived next door stood outside with a large bowl of Boriala fish. Her husband had gone fishing on the Subansiri River, which flows next to the village, and he had fished all evening. “My husband cannot stay indoors in this weather,” she said in Assamese, the local language. “You can catch a lot of fish during this time.” The monsoon season has long brought a bounty of fish from May to September for people living downstream. However, this is likely to change once the Subansiri Lower Hydroelectric Project, one of the largest hydropower dams in India, is completed upstream. Expected to be fully op...
