Sudden loss of key US satellite data could send hurricane forecasting back ‘decades'
The Department of Defense will halt a critical atmospheric data collection program at the end of June and has given weather forecasters just days to prepare, according to a public notice sent this week. Scientists that the Guardian spoke with say the change could set hurricane forecasting back 'decades', just as this year's season ramps up.
In a National Oceanic and Atmospheric Administration (Noaa) message sent on Wednesday to its scientists, the agency said that 'due to recent service changes' the Defense Meteorological Satellite Program (DMSP) will 'discontinue ingest, processing and distribution of all DMSP data no later than June 30, 2025'.
Due to their unique characteristics and ability to map the entire world twice a day with extremely high resolution, the three DMSP satellites are a primary source of information for scientists to monitor Arctic sea ice and hurricane development. The DMSP partners with Noaa to make weather data collected from the satellites publicly available.
Noaa said the changes would not impact the quality of forecasting.
However, the Guardian spoke with several scientists inside and outside of the US government whose work depends on the DMSP, and all said there are no other US programs that can form an adequate replacement for its data.
'We're a bit blind now,' said Allison Wing, a hurricane researcher at Florida State University. Wing said the DMSP satellites are the only ones that let scientists see inside the clouds of developing hurricanes, giving them a critical edge in forecasting that now may be jeopardized.
'Before these types of satellites were present, there would often be situations where you'd wake up in the morning and have a big surprise about what the hurricane looked like,' said Wing. 'Given increases in hurricane intensity and increasing prevalence towards rapid intensification in recent years, it's not a good time to have less information.'
The satellites also formed a unique source of data for tracking changes to the Arctic and Antarctic, and had been tracking changes to polar sea ice continuously for more than 40 years.
'These are some of the regions that are changing the fastest around the planet,' said Carlos Moffat, an oceanographer at the University of Delaware who had been working on a research project in Antarctica that depended on DMSP data. 'This new announcement about the sea ice data really amounts to blinding ourselves and preventing us from observing these critical systems.'
Researchers say the satellites themselves are operating normally and do not appear to have suffered any errors that would physically prevent the data from continuing to be collected and distributed, so the abrupt data halt might have been an intentional decision.
'It's pretty shocking,' Moffat said. 'It's hard to imagine what would be the logic of removing access now and in such a sudden manner that it's just impossible to plan for. I certainly don't know of any other previous cases where we're taking away data that is being collected, and we're just removing it from public access.'
The loss of DMSP comes as Noaa's weather and climate monitoring services have become critically understaffed this year as Donald Trump's so-called 'department of government efficiency' (Doge) initiative has instilled draconian cuts to federal environmental programs.
A current Noaa scientist who wishes to remain anonymous for fear of retaliation said that the action to halt the DMSP, when taken in context with other recent moves by the Trump administration, amounted to 'a systematic destruction of science'.
The researcher also confirmed that federal hurricane forecasters were left unprepared for the sudden change with only a few days of notice.
'It's an instant loss of roughly half of our capabilities,' said the scientist. 'You can't expect us to make accurate forecasts and warnings when you take the useful tools away. It frankly is an embarrassment for the government to pursue a course with less data and just pretend everything will be OK.'
Scientists said the decision to halt the DMSP will result in immediately degraded hurricane forecasts during what is expected to be an above-average season as well as a gap in monitoring sea ice – just as Arctic sea ice is hitting new record lows.
'This is a huge hit to our forecasting capabilities this season and beyond, especially our ability to predict rapid intensification or estimate the strength of storms in the absence of hurricane hunters,' said Michael Lowry, a meteorologist who has worked at Noaa's National Hurricane Center and with the Federal Emergency Management Agency. 'The permanent discontinuation of data from these satellites is senseless, reckless and puts at risk the lives of tens of millions of Americans living in hurricane alley.'
The DMSP dates back to 1963, when the Department of Defense determined a need for high-resolution cloud forecasts to help them plan spy missions. The program, which had been the longest-running weather satellite initiative in the federal government, has since evolved into a critical source of information not just on the inner workings of hurricanes, but also on polar sea ice, wildfires, solar flares and the aurora.
In recent years, the DMSP had struggled to maintain consistent funding and priority within the Department of Defense as it transitioned away from its Cold war mission. The only other nation with similar satellite capability is Japan, and messages posted earlier in June indicate that scientists had already been considering a switch to the Japanese data in case of a DMSP outage – though that transition will take time.
Neither Noaa nor the Department of Defense specified exactly which service changes may have prompted such a critical program to be so abruptly halted.
In a statement to the Guardian, Noaa's communications director, Kim Doster, said: 'The DMSP is a single dataset in a robust suite of hurricane forecasting and modeling tools in the National Weather Service portfolio. This routine process of data rotation and replacement would go unnoticed in past administrations, but the media is insistent on criticizing the great work that Noaa and its dedicated scientists perform every day.
'Noaa's data sources are fully capable of providing a complete suite of cutting-edge data and models that ensure the gold-standard weather forecasting the American people deserve.'
One Noaa source the Guardian spoke to said the loss of DMSP's high-resolution data could not be replaced by any other existing Noaa tool.
The Guardian has also reached out to the Department of Defense for further explanation and will update this story with any response.

Mark Zuckerberg's charity backing away from DEI and political spending after Trump criticisms and staff tensions: report
The Chan Zuckerberg Initiative, the multi-billion-dollar philanthropy led by Meta CEO Mark Zuckerberg and his wife Dr. Priscilla Chan, is reportedly moving away from political spending, following criticism from Republicans and internal tensions with liberal staff members. The initiative, founded in 2015, always invested in a combination of social and scientific causes, but has recently rebranded as 'science-first,' and has ended internal diversity programs, housing initiatives, and diversity-focused funding for scientists. This spring, a school for low-income students that Chan founded also closed. The shift, which has also included an overall slowdown in spending, with $336 million in grants, less than half the group's average, came after a series of bruising encounters with politics, The New York Times reports. Chan and Zuckerberg were reportedly frustrated after getting criticism from Trump and his allies for efforts like donating $400 million to nonpartisan election infrastructure in the 2020 race, an effort MAGA derided as 'Zuckerberg bucks.' Trump, for his part, threatened the Meta boss with 'life in prison' during the 2024 campaign if he intervened in the election. Political fatigue reportedly began even earlier, according to the Times, with Zuckerberg growing frustrated with criticisms from liberal staff members at the philanthropy in the wake of the 2020 racial justice protests. The Independent has contacted the Chan Zuckerberg Initiative for comment. The organization has explained the changes as a combination of new strategy and a shifting political landscape. In a June letter, Chan, a pediatrician, emphasized the group's long-running commitment to curing disease, a cause she became attached to as a doctor in San Francisco. 'It was there that I saw the limits of medicine and science up close, working with children with rare diseases,' she wrote in a June blog post. 'For those families, expanding the limits of what we know — advancing basic science research — is their only hope for a better life for their child. In a February post, the initiative explained its decision to cut its DEI teams as a response to the ' shifting regulatory and legal landscape.' In recent years, the Supreme Court has struck down race-based affirmative action in higher education admissions, and the Trump administration has sought to end DEI in both the public and private sector. At the same time, as the Republican has returned to power, Meta has repositioned itself with moves seen by some as an attempt to remain in the administration's good graces, including ending diversity programs, eliminating fact-checkers, putting Trump ally Dana White on the Meta board, and attending the president's inauguration earlier this year. Shortly after Trump was elected, Zuckerberg was spotted at Trump's Mar-a-Lago estate, where senior White House official Stephen Miller said the tech billionaire had 'been very clear about his desire to be a supporter of and a participant in this change that we're seeing all around America, all around the world, with this reform movement that Donald Trump is leading.'

The American women who are making Elon Musk's doomsday prediction a reality
Elon Musk has warned for years that 'population collapse' is a bigger threat to civilization than climate change. Now, new research has suggested that American women may be quietly proving him right. The study looked at the fertility intentions of over 41,000 women aged 15 to 44, finding that 50 percent of them were uncertain if they would have children in the future, even though they desired to be a mother. Researchers found that economic pressures, social shifts, and emotional uncertainty are driving a growing disconnect. The data also showed that uncertainty about having children isn't the same for all, and younger women are experiencing the biggest changes. Women aged 15 to 29 became increasingly unsure not only about whether they would have children, but also how strongly they felt about wanting them. In contrast, women aged 30 to 44 showed relatively stable levels of certainty over time. The data was collected from 2002 through 2019, which the team speculated revealed why US birth rates have been on a steady decline since the 2007 Great Recession. The fertility rate has decreased by 21 percent between 2007 and 2024. Musk, the billionaire father of 14 children, has often pointed to declining fertility as a sign that modern societies are forgetting how to survive. He previously said that low birth rates mean few workers, increased debt, strained healthcare and pension systems, and total social unrest. The US fertility rate was stable at about 2.0 children per woman in the 1990s and early 2000s, reaching a peak of 2.12 in 2007, statistics show. But the fertility rate steadily declined in the aftermath of the Great Recession, falling to 1.62 in 2023. Sarah Hayford, co-author of the study and professor of sociology at The Ohio State University, told Ohio State News: 'People's feelings about having children are complicated, and we found there are a lot of nuances. 'It suggests that there is no simple answer to the declining birth rate in the US.' The study used data from the National Survey of Family Growth, a federally funded survey conducted by the National Center for Health Statistics. Over the years studied, the team found that 62 percent of women said they intended to have a child and 35 percent did not intend to, with only a small percentage saying they didn't know. But up to half of the participants who intended to have children said they were only 'somewhat sure' or 'not sure at all' that they would realize their intention to have a child. The team found that women with higher incomes and education levels were more inclined to report 'very sure' that they would have children than those on the opposite side of the spectrum. Levels of certainty among women considering having children, showing the percentage who said they were not at all sure, somewhat sure, or very sure. Data includes confidence intervals and is grouped by parental status (b) and age (c). However, women with a bachelor's degree who gave that answer declined from 65 percent in 2014 to 54 percent in 2018. The data revealed another pattern holding women back from having children -the actual desire to be a mother. Up to 25 percent of childless women wouldn't be bothered if they never had kids. 'This not being bothered was especially high among younger women, and it increased over time among those who were younger,' Hayford said. 'They are open to different pathways and different kinds of lives. If they don't become parents for whatever reason, it doesn't seem that upsetting to many of them.' One commonly suggested reason for the declining birth rate is that young people today feel uncertain about the future, both of the country and the world, which may be causing them to delay or avoid having children. The team conducted a second study, surveying 3,696 people, which found that the more disassified they were with their own lives, the less likely they were to want a child. 'It was a bit of a surprise to us, but it was only their personal situation that mattered in whether they expected to have children,' Hayford said. 'It wasn't so much what was going on in society that predicted their fertility goals.'

Jannik Sinner's three-month drugs ban from tennis felt all too convenient, too light on the fading principle of strict liability... excuse those of us rooting for Carlos Alcaraz at Wimbledon, writes RIATH AL-SAMARRAI
This is a true story - a dog once ate my homework. Well, he clawed a couple of pages into a state of disrepair, but my geography teacher didn't quite buy that a border collie was solely responsible for late submission. Nor did a different teacher when the same pet peed on my sister's English essay. I miss that dog, a good boy mostly, but I also wonder what those teachers might have brought to the arbitration of doping disputes in elite sport.
