Hotter summers could be making us sicker in unexpected ways
As the earth experiences hotter and hotter summers, new research using data from California emergency departments shows that the heat may be making us sicker than we know, and in ways we may not anticipate. A study published Wednesday in the journal Science Advances tracked emergency department visits and fatalities in the state over the course of 11 years and found that while deaths increased both in cold and hot temperatures, especially among older adults, emergency room visits steadily increased as temperatures did - particularly among young children. Subscribe to The Post Most newsletter for the most important and interesting stories from The Washington Post. The findings underscore the impact that a hotter planet has on lives, health and medical infrastructure. While scientists have spent decades covering how extreme heat and cold lead to death, 'we have a relatively poor understanding of whether those relationships are the same for morbidity - rates of disease and poor health,' said Carlos Gould, the paper's lead author and an environmental health scientist at the University of California San Diego. The focus on fatalities could be because of how deadly heat is - it's the most lethal form of extreme weather. High temperatures have been linked to cardiovascular deaths, chronic kidney disease mortality and respiratory failure. Heat can put undue stress on organs: The heart pumps faster to get blood flow to the skin; kidneys work harder to preserve the body's water. Those with preexisting conditions are more at risk in hot weather. The cold kills more people than heat does. As Earth warms, some projections indicate that temperature-related fatalities could decrease, but the effects would be unequal: Hotter and poorer countries would see an increase in deaths, while colder, wealthier countries would see a decrease. Some researchers contend it's a fraught comparison to begin with. 'It remains problematic to trade off mortality and morbidity from hot versus cold temperature extremes,' said Kristie Ebi, a professor at the Center for Health and Global Environment at the University of Washington. 'People are not fungible. The goal of public health is to prevent as much morbidity and mortality as possible.' Gould said deaths are just the tip of the iceberg when it comes to temperature's effects on society. Between 2006 and 2017, more people in California visited emergency rooms as temperatures went up, further burdening public health systems as the world got hotter. 'It is helpful to have more detailed analyses of temperature-morbidity relationships, to help identify interventions that could decrease hospitalizations during heat waves,' said Ebi. Gould added that while he was reluctant to generalize beyond the data from California, its rates of mortality to extreme temperatures were in line with those from across the country. The study found that as temperatures increased, more people visited emergency rooms for illnesses including those linked to poison, respiratory symptoms and nervous system problems. Data also showed that children under 5 visited emergency rooms at a higher rate than any other age group. 'Hot days can worsen our health far before they lead to deaths,' said Gould. 'And it can be a large range of things that we get sick from.' In some cases, it's difficult to know how these illnesses are linked to heat, said Robert Meade a research fellow at the Harvard T.H. Chan School of Public Health who studies heat's impacts on the human body. It could be an error in how the data was analyzed, or it could further highlight the challenge of anticipating heat's indirect effects on our health. For example, researchers cautioned against using the data to draw a direct link between hotter temperatures and more poison-related illness. 'The mechanisms might not be clear to us, but it still could reflect a very complex interaction between heat and people's behavior that causes this rise,' Meade added. Ebi also noted that the analyses didn't consider other factors, such as wildfires, which are drivers of cardiovascular and respiratory illnesses and mortality, especially in California. 'Climate change is increasing the numbers of wildfires, which could have influenced the results because wildfires are often associated with hot days,' she said. She also pointed out that the data ends in 2017, which means it missed many large, extreme heat waves over the last 7½ years that could have altered the way we respond to heat exposure. Gould hopes the data will help public health officials broaden their understanding of who needs to be protected during heat waves. 'Deaths are of course the most severe outcome, and protecting deaths is one of the single largest priorities of public health,' he said. 'But these illnesses can affect kids, working families, reduce our productivity and strain our hospitals and communities.' 'Even when heat doesn't kill,' said Gould, 'it hurts a lot.' - - - Kevin Crowe contributed to this report.

Fact Check: Probing claim that interstellar object is 'most likely' an alien ship heading towards Earth
Claim: In July 2025, scientists discovered a mysterious intergalactic object that was "most likely" an alien ship that could reach Earth by November 2025. Rating: Rumors of an incoming alien attack invaded some social media feeds in late July 2025 after the New York Post published an article about a potential "alien probe." While the article only said the object in question "could" be an alien probe, posts on social media described the situation with far more alarm. For example, an Instagram post (archived) with 15,000 likes warned of an "intergalactic object" that was "most likely" an alien ship heading toward Earth. A Facebook post (archived) with 12,000 reactions sarcastically said an astrophysicist was "certain" the object was an alien ship, a claim many in the comments appeared to take at face value. An X post (archived) viewed more than 1.4 million times claimed a hostile alien ship was headed for Earth within the next three months. A TikTok video (archived) claimed that scientists said a "dangerous alien ship" was heading toward Earth and would arrive within the year. A Snopes reader asked us to fact-check the claim. The claim was false. Scientists did not warn that an "intergalactic" object was "most likely" or "certainly" an alien ship heading toward Earth. The overwhelming scientific consensus was that the object was likely an interstellar comet. A few scientists published a paper analyzing a theoretical argument that it could be an alien ship, but even the paper's authors believed it to most likely be a comet. On July 1, 2025, scientists discovered 3I/ATLAS, an interstellar object both NASA and the European Space Agency have called a comet. (An "interstellar" object is one that travels between star systems, hundreds of billions of which can be found in the Milky Way galaxy alone. An "intergalactic" object travels between galaxies, and therefore such an object by definition must originate outside the Milky Way.) The idea that the object was an alien ship came from misunderstandings and misrepresentations of a paper titled "Is the Interstellar Object 3I/ATLAS Alien Technology?" by Harvard astrophysicist Abraham "Avi" Loeb and two researchers from the United Kingdom. But despite the title of the paper, which had not been peer-reviewed by the time it spread on social media, the paper's authors did not believe the answer to the question in the title was "yes." "By far the most likely outcome will be that 3I/ATLAS is a completely natural interstellar object, probably a comet, and the authors await the astronomical data to support this likely origin," wrote the scientists in the paper's conclusion. In the paper's introduction, the authors wrote that one of the reasons for analyzing the hypothesis that the comet could actually be alien technology was that "The hypothesis is an interesting exercise in its own right, and is fun to pursue, irrespective of its likely validity." The scientists wrote that if the object was alien technology, its intentions would be either harmless, malicious or somewhere in between. Because humanity would need to do nothing if an alien craft had harmless intentions, according to the paper's authors, the possibility that it could be malicious would be of more concern. Thus, the paper assumed the object would be dangerous to humans if it were an alien ship. After its discovery of the object, NASA said on an informational webpage that 3I/ATLAS would "remain far away" and pose "no threat to Earth." The hypothesis that 3I/ATLAS could reach Earth by November wasn't based on the current projected path of the object. Instead, the authors of the paper estimated the arrival time based on maneuvers a theoretical alien ship could make using the gravity of the Sun or Jupiter to launch such a ship in the direction of Earth. This was not the first time that Loeb, the Harvard astrophysicist, tried to encourage other scientists to consider the unlikely hypothesis that an interstellar object could be of artificial origin. In 2017, after the discovery of the first recorded interstellar object to enter the solar system, Loeb told The Guardian, "Most likely it is of natural origin, but because it is so peculiar, we would like to check if it has any sign of artificial origin, such as radio emissions."
