Most US Christian leaders believe climate change is real: Study
A mammoth 90 percent of American Christian leaders — from Catholics to evangelicals — believe in the reality of human-induced climate change, a new study has found.
However, these same leaders are typically silent in their beliefs and fail to share that understanding with their congregants, according to the study, recently published in the Proceedings of the National Academy of Sciences.
'Because of leadership's silence on the matter, rank-and-file Christians think most of their leaders do not believe,' senior author Gregg Sparkman, an assistant professor at Boston College, said in a statement.
As a result, Sparkman explained, those same congregants 'feel hesitant to even discuss climate change with their fellow churchgoers.'
Sparkman and author Stylianos Syropoulos, now an assistant professor at Arizona State University, drew their conclusions based on a survey of 1,600 Christian leaders across the country.
Of these leaders, they found that nearly 90 percent said they believed in anthropogenic climate change to at least some degree.
Some 60 percent of the leaders replied that humans play a major role, while 30 percent said they felt that people have had more minor impacts, according to the survey.
Breaking the data down further, the researchers observed that more than 80 percent of evangelical or fundamentalist Christian leaders believe that humans have contributed to climate change.
Nonetheless, the authors also found that about half of the respondents have never discussed this issue with their congregants — and that only a quarter have mentioned it more than once or twice.
A second survey included in the study showed that U.S. Christians broadly underestimate the prevalence of their leaders who believe in climate change. Although these participants guessed that about half of their leaders were climate-change deniers, only about 10 percent truly fell into that category, per the study.
In a third set of survey results, about half of 1,000 respondents were informed that 90 percent of Christian leaders believe in manmade climate change. That newfound awareness then increased their perception that other church members believe in or are opening to discussing this fraught issue.
As such, more respondents answered that taking climate action would be consistent with church values, while voting for politicians who oppose doing so is not, according to the findings.
'We find that informing Christians that the majority of their religious leaders believe in man-made climate change leads them to realize that climate action is in line with their morals, and voting for politicians who deny climate change may be at odds with their faith,' Sparkman said.
Noting that every year, droughts, fires, floods and other extreme weather events become more common, he stressed that 9 out of 10 Christian leaders already believe that humans have a role to play in these phenomena.
'If this truth gets out and they break their silence, it will help Christian Americans come to faith on this dire issue,' Sparkman added.

'Diving into a different world': Why an ASU professor studies the ocean in the desert
When Susanne Neuer closed her eyes, she could see it: the crystal clear waters of the Mediterranean. A smile broke out on her face as she reminisced about the times her family visited the coastline of Ibiza. She has fallen in love with the ocean over and over, each time her family visited when she was young. She pictured a life on a boat fitted with all sorts of research equipment, salt in her face and the waves beneath her feet. No land for miles and miles. And she had that life, for a little bit. Her research cruises were far from luxurious. Neuer said they were "spartan" in a way. But they were exactly what she wanted. "Just the sea in all its different states," she said. "The terrible waves that make me seasick or a smooth ocean and beautiful sunsets, and then the animals, the dolphins that come about and play in the wake of the ship," Neuer said, her cadence speeding up with excitement. "It's really diving into a different world." Neuer's life took a sharp left turn to the desert in 2000 when she landed in Arizona after her husband got a job at Arizona State University. The desert landscape was a stark difference from the glittering blue waves dotted with bioluminescent plankton. She eventually found her place in Arizona, becoming a world-renowned researcher studying the role of ocean life in the carbon cycle. In 2022, Neuer was named the founding director of Arizona State University's School of Ocean Futures, a unique position to teach desert dwellers about the ocean. Neuer, 62, grew up in southern Germany, hundreds of miles away from the ocean in all directions. But her family vacationed in Ibiza, a Spanish island, and the ocean waves lapped at the edges of her mind. She wanted to learn more about the ocean. So, she turned to the ponds and streams that surrounded her hometown, flipping over rocks and digging into the dirt and mud. When she was in her early teens, she worked one summer at a garden shop to buy her own microscope so she could uncover the mysteries in the water. It changed her life. She knew it then, that she would study the ocean and the microorganisms that were only revealed to her through the microscope on those summer days. Her university studies took her first to the University of Heidelberg in west Germany, then north to the University of Kiel on the Baltic Sea, a far cry from the warm embrace of the Mediterranean. It was one of the only places Neuer could study marine science, she said. Then, she found out about the Fulbright Program, and she was accepted at the University of Washington to study oceanography. She planned to only stay in the U.S. for a year until she met her husband on a trip to California with other Fulbright students. "I realized that, you know, that this was probably serious," Neuer said. She and her husband, who was from Spain, decided to stay and finish out their studies in the U.S. They had a daughter, finished their doctoral degrees and moved back to Germany for postdoctoral work. The family stayed in Germany for six years. "There was, back then, no way we could stay both and get both permanent positions in Germany," she said. "We said the first one who would get at tenure track offer would take the other one along." Her husband beat her to the punch. He landed a job at ASU in the middle of the Sonoran Desert, perfect for his career as a microbiologist focused on desert soil. Not so perfect for Neuer's career in oceanography. When Neuer arrived in Arizona in 2000, she was lonely. The lone oceanographer in a sea of sand and hours away from the brilliant blue ocean — again. She followed her husband's lead and got a job at ASU. She taught oceanography through the geology department and spent more time with geologists than biologists. She tried teaching as many courses about marine life as possible and ended up pioneering degrees focused on environmental and marine sciences. She fell in love with teaching, even if it meant being in the desert. She said that's a benefit, not a detriment. "You can't really understand our planet and how our planet works without the oceans," Neuer said. "(The ocean) is so intricately engrained in our climate and our weather. ... Here in Arizona, you know, we receive water that enables life in the desert, and that water has come evaporated from the ocean." As the years dragged on, she was still the only oceanographer at the university. Sure, there were biologists and geologists and other "ologists," but none focused solely on the ocean, like Neuer. She eventually found a home in the School of Life Sciences, where her programs lived for 20 years. She developed curricula for students and led the graduate program. That's how she met Jesse Senko. Senko was at ASU as a doctoral candidate studying biology in 2011. Senko, from Connecticut, had planned on staying in Arizona for four years, just long enough to get his degree. His dream was to study marine life, specifically sea turtles. He wasn't sure if he was going to make it if not for Neuer. "She provided a safe space for me," Senko said. "If it wasn't for her, I definitely would've left the school, and I don't even know if I would've gotten a Ph.D." More than 10 years later, Senko hasn't left Arizona. He hasn't even left ASU, all because of Neuer. After years of being the lone oceanographer, Neuer founded a home for people like her. Like Senko. Those passionate about the ocean while loving the desert. Neuer was named the director of ASU's School of Ocean Futures in 2022, a "180-degree turn from being the lonely oceanographer to becoming the founding director of that school," she said. The school opened in 2023 and began offering degree programs in 2024. Students are able to study from across the world, from Hawaii to Bermuda. Senko teaches at the school and leads students on research trips to Baja California in northwest Mexico to study sea turtles. "We are connected," Neuer said, "considering the ocean as a home."

Art-eating fungus attacks Rome's ancient underground frescoes
A devastating infestation of microbugs is damaging the treasured underground frescoes that decorate the labyrinths of ancient catacombs beneath Rome. A vast network of tunnels, dug into the soft, porous tufa rock that underlies much of the city, was created in the early Christian era for the burial of the dead. They were also used as clandestine meeting places at a time when Christians were persecuted by Rome's emperors. But the colourful frescoes that adorn the ceilings and walls of the catacombs are being eaten away by microorganisms, a phenomenon that experts say is being accelerated by climate change. Rising temperatures have increased humidity levels inside the underground burial sites, encouraging the growth of bacteria, moss and fungus. The alarm about the rampant art-eating fungus has been raised by a Vatican department, the Pontifical Commission for Sacred Archaeology. 'The survival of frescoes which were created 2,000 years ago is at risk,' said Monsignor Pasquale Iacobone, the head of the department. 'There is an increase in the proliferation of vegetation and the damage is unprecedented. It's the effect of climate change and the increase in outside temperatures.' Ancient Romans, who cremated their dead, banned Christians from burying corpses within the walls of the capital. So the Christians instead dug underground passageways for the interment of their dead, eventually excavating around 300kms of tunnels beneath Rome. They wrapped the dead in shrouds and laid them to rest in rectangular niches that were carved out of the tunnel walls. Among the treasures under threat are striking frescoes in the San Callisto Catacomb, which mark some of the earliest surviving examples of Christian art. San Callisto, the biggest and most famous of Rome's catacombs, was established in the second century AD and contained the remains of about half a million people, as well as seven popes who were martyred in the third century AD. 'Along with the six catacombs that are open to the public, the problem is affecting all 400 of the decorated chambers that exist in Rome's 60 catacombs. We are seeing an unexpected increase in biological infestations,' Barbara Mazzei, an archaeologist and an expert on the catacombs, told Corriere della Sera newspaper. While the problem underground is high humidity, the issue above ground is a lack of moisture – high temperatures and drought conditions mean that trees are sinking their roots deeper, breaking through the ceilings of the catacombs and penetrating the frescoes. The confined, subterranean nature of catacombs and the lack of ventilation mean that it is hard for experts to use chemicals such as biocides to combat the growth of bacteria and mould. Instead, they are experimenting with natural products that are not harmful to humans, including essential oils made from lavender, thyme and cinnamon. The threats faced by the catacombs were revealed at a seminar in Rome organised by the International Institute for Conservation of Historic and Artistic Works. Many of the catacombs lie beneath the Appian Way, the 'regina viarum' or 'queen of roads' that once ran from Rome to the distant port of Brindisi on the Adriatic coast. In 2010, the earliest known icons of four of Christ's apostles were discovered on the ceiling of an elaborately decorated chamber in a catacomb beneath the streets of Rome. Scientists used advanced laser technology to remove a hardened crust of dirt and calcium deposits in order to bring to light the brightly coloured fourth century paintings of Saints John, Paul, Andrew and Peter. The images adorn the ceiling of a vault, carved out of volcanic rock, which provided the last resting place of a rich Roman noblewoman who converted to Christianity. Archaeologists also found an early image of Christ, a painting of a naked Daniel with lions at his feet and a sketch of Jesus raising Lazarus from the dead. The catacombs of Santa Tecla, a labyrinth of tunnels, galleries and burial chambers, lie hidden beneath a five-storey office in Ostiense, a residential area of Rome.

A surprising study revealed biological activity on a distant planet. Weeks later, scientists say there's more to the story
Sign up for CNN's Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more. A tiny sign revealed in April seemed like it might change the universe as we know it. Astronomers had detected just a hint, a glimmer of two molecules swirling in the atmosphere of a distant planet called K2-18b — molecules that on Earth are produced only by living things. It was a tantalizing prospect: the most promising evidence yet of an extraterrestrial biosignature, or traces of life linked to biological activity. But only weeks later, new findings suggest the search must continue. 'It was exciting, but it immediately raised several red flags because that claim of a potential biosignature would be historic, but also the significance or the strength of the statistical evidence seemed to be too high for the data,' said Dr. Luis Welbanks, a postdoctoral research scholar at Arizona State University's School of Earth and Space Exploration. While the molecules identified on K2-18b by the April study — dimethyl sulfide, or DMS, and dimethyl disulfide, or DMDS — are associated largely with microbial organisms on our planet, scientists point out that the compounds can also form without the presence of life. Now, three teams of astronomers not involved with the research, including Welbanks, have assessed the models and data used in the original biosignature discovery and got very different results, which they have submitted for peer review. Meanwhile, the lead author of the April study, Nikku Madhusudhan, and his colleagues have conducted additional research that they say reinforces their previous finding about the planet. And it's likely that additional observations and research from multiple groups of scientists are on the horizon. The succession of research papers revolving around K2-18b offers a glimpse of the scientific process unfolding in real time. It's a window into the complexities and nuances of how researchers search for evidence of life beyond Earth — and shows why the burden of proof is so high and difficult to reach. Located 124 light-years from Earth, K2-18b is generally considered a worthy target to scour for signs of life. It is thought to be a Hycean world, a planet entirely covered in liquid water with a hydrogen-rich atmosphere, according to previous research led by Madhusudhan, a professor of astrophysics and exoplanetary science at the University of Cambridge's Institute of Astronomy. And as such, K2-18b has rapidly attracted attention as a potentially habitable place beyond our solar system. Convinced of K2-18b's promise, Madhusudhan and his Cambridge colleagues used observations of the planet by the largest space telescope in operation, the James Webb Space Telescope, to study the planet further. But two scientists at the University of Chicago — Dr. Rafael Luque, a postdoctoral scholar in the university's department of astronomy and astrophysics, and Michael Zhang, a 51 Pegasi b / Burbidge postdoctoral fellow — spotted some problems with what they found. After reviewing Madhusudhan and his team's April paper, which followed up on their 2023 research, Luque and Zhang noticed that the Webb data looked 'noisy,' Luque said. Noise, caused by imperfections in the telescope and the rate at which different particles of light reach the telescope, is just one challenge astronomers face when they study distant exoplanets. Noise can distort observations and introduce uncertainties into the data, Zhang said. Trying to detect specific gases in distant exoplanet atmospheres introduces even more uncertainty. The most noticeable features from a gas like dimethyl sulfide stem from a bond of hydrogen and carbon molecules — a connection that can stretch and bend and absorb light at different wavelengths, making it hard to definitively detect one kind of molecule, Zhang said. 'The problem is basically every organic molecule has a carbon-hydrogen bond,' Zhang said. 'There's hundreds of millions of those molecules, and so these features are not unique. If you have perfect data, you can probably distinguish between different molecules. But if you don't have perfect data, a lot of molecules, especially organic molecules, look very similar, especially in the near-infrared.' Delving further into the paper, Luque and Zhang also noticed that the perceived temperature of the planet appeared to increase sharply from a range of about 250 Kelvin to 300 Kelvin (-9.67 F to 80.33 F or -23.15 C to 26.85 C) in research Madhusudhan published in 2023 to 422 Kelvin (299.93 F or 148.85 C) in the April study. Such harsh temperatures could change the way astronomers think about the planet's potential habitability, Zhang said, especially because cooler temperatures persist in the top of the atmosphere — the area that Webb can detect — and the surface or ocean below would likely have even higher temperatures. 'This is just an inference only from the atmosphere, but it would certainly affect how we think about the planet in general,' Luque said. Part of the issue, he said, is that the April analysis didn't include data collected from all three Webb instruments Madhusudhan's team used over the past few years. So Luque, Zhang and their colleagues conducted a study combining all the available data to see whether they could achieve the same results, or even find a higher amount of dimethyl sulfide. They found 'insufficient evidence' of both molecules in the planet's atmosphere. Instead, Luque and Zhang's team spotted other molecules, like ethane, that could fit the same profile. But ethane does not signify life. Arizona State's Welbanks and his colleagues, including Dr. Matt Nixon, a postdoctoral researcher in the department of astronomy at the University of Maryland College Park, also found what they consider a fundamental problem with the April paper on K2-18b. The concern, Welbanks said, was with how Madhusudhan and his team created models to show which molecules might be in the planet's atmosphere. 'Each (molecule) is tested one at a time against the same minimal baseline, meaning every single model has an artificial advantage: It is the only explanation permitted,' Welbanks said. When Welbanks and his team conducted their own analysis, they expanded the model from Madhusudhan's study. '(Madhusudhan and his colleagues) didn't allow for any other chemical species that could potentially be producing these small signals or observations,' Nixon said. 'So the main thing we wanted to do was assess whether other chemical species could provide an adequate fit to the data.' When the model was expanded, the evidence for dimethyl sulfide or dimethyl disulfide 'just disappears,' Welbanks said. Madhusudhan believes the studies that have come out after his April paper are 'very encouraging' and 'enabling a healthy discussion on the interpretation of our data on K2-18b.' He reviewed Luque and Zhang's work and agreed that their findings don't show a 'strong detection for DMS or DMDS.' When Madhusudhan's team published the paper in April, he said the observations reached the three-sigma level of significance, or a 0.3% probability that the detections occurred by chance. For a scientific discovery that is highly unlikely to have occurred by chance, the observations must meet a five-sigma threshold, or below a 0.00006% probability that the observations occurred by chance. Meeting such a threshold will require many steps, Welbanks said, including repeated detections of the same molecule using multiple telescopes and ruling out potential nonbiological sources. While such evidence could be found in our lifetime, it is less likely to be a eureka moment and more a slow build requiring a consensus among astronomers, physicists, biologists and chemists. 'We have never reached that level of evidence in any of our studies,' Madhusudhan wrote in an email. 'We have only found evidence at or below 3-sigma in our two previous studies (Madhusudhan et al. 2023 and 2025). We refer to this as moderate evidence or hints but not a strong detection. I agree with (Luque and Zhang's) claim which is consistent with our study and we have discussed the need for stronger evidence extensively in our study and communications.' In response to the research conducted by Welbanks' team, Madhusudhan and his Cambridge colleagues have authored another manuscript expanding the search on K2-18b to include 650 types of molecules. They have submitted the new analysis for peer review. 'This is the largest search for chemical signatures in an exoplanet to date, using all the available data for K2-18b and searching through 650 molecules,' Madhusudhan said. 'We find that DMS continues to be a promising candidate molecule in this planet, though more observations are required for a firm detection as we have noted in our previous studies.' Welbanks and Nixon were pleased that Madhusudhan and his colleagues addressed the concerns raised but feel that the new paper effectively walks back central claims made in the original April study, Welbanks said. 'The new paper tacitly concedes that the DMS/DMDS detection was not robust, yet still relies on the same flawed statistical framework and a selective reading of its own results,' Welbanks said in an email. 'While the tone is more cautious (sometimes), the methodology continues to obscure the true level of uncertainty. The statistical significance claimed in earlier work was the product of arbitrary modeling decisions that are not acknowledged.' Luque said the Cambridge team's new paper is a step in the right direction because it explores other possible chemical biosignatures. 'But I think it fell short in the scope,' Luque said. 'I think it restricted itself too much into being a rebuttal to the (Welbanks) paper.' Separately, however, the astronomers studying K2-18b agree that pushing forward on researching the exoplanet contributes to the scientific process. 'I think it's just a good, healthy scientific discourse to talk about what is going on with this planet,' Welbanks said. 'Regardless of what any single author group says right now, we don't have a silver bullet. But that is exactly why this is exciting, because we know that we're the closest we have ever been (to finding a biosignature), and I think we may get it within our lifetime, but right now, we're not there. That is not a failure. We're testing bold ideas.'
