Data Crucial to Hurricane Forecasts Will Continue, but for One Month Only
The National Atmospheric and Oceanic Administration announced last week that data from three satellites jointly run by NOAA and the Defense Department would become unavailable for researchers and forecasters no later than June 30. 'Recent service changes' was the only explanation provided.
An announcement from NOAA on Monday cites a 'significant cybersecurity risk' as the reason for taking the data offline. The decision to continue supplying the data came in response to a request from a NASA scientist, according to the update.
Meteorologists and other climate scientists responded to the original announcement with confusion and dismay. Losing access to the data would immediately degrade the quality of hurricane forecasts, increasing risk to life and property in the United States and elsewhere, experts said.
The Department of Defense did not immediately respond to questions about the reason for the data cancellation, the reason for the delay or the reason for the timeline. NOAA declined to comment.
'The extension of this crucial data through July by direct NASA order speaks to how blindsided government forecasters were by the DoD's sudden decision to terminate the data,' said Michael Lowry, a hurricane expert who has worked at the National Hurricane Center and the Federal Emergency Management Agency.
'It unfortunately doesn't get us to the peak months of hurricane season in August, September and October when our strongest hurricanes typically form and rapid intensification is most common,' he said.
Hurricanes forecasts would not be the only important climate research affected.
The canceled data services are critical for researchers studying changes in sea ice in the Arctic and Antarctic since the 1970s, said Sharon Stammerjohn, a senior research associate at the University of Colorado Boulder's Institute of Arctic and Alpine Research.
Sea ice in the Earth's polar regions melts in the summer and refreezes in the winter, helping the planet cool down by reflecting solar energy into space. At the planet warms, satellite imagery allows scientists to track the seasonal decline of sea ice.
'Without that record, especially for the Antarctic, because it's so remote, we wouldn't be able to observe these changes that are so critical to our global climate,' Dr. Stammerjohn said. 'Most people are much more aware of hurricanes than they are of polar sea ice.'While other satellite products, including ones maintained by the European Space Agency and the Japan Aerospace Exploration Agency, may be able to fill the gap, Dr. Stammerjohn said, there are challenges in accounting for variations in the data, such as differently-calibrated sensors and resolutions.

Congressionally mandated climate reports have disappeared from their federal websites
Legally mandated national climate assessments disappeared this week from the federal websites built to display them, making it harder for state and local governments and the public to learn what to expect in their backyards from a warming world. Scientists said the peer-reviewed authoritative reports save money and lives. Websites for the national assessments and the US Global Change Research Program were down Monday and Tuesday with no links, notes or referrals elsewhere. The White House, which was responsible for the assessments, said the information will be housed within NASA to comply with the law, but gave no further details. Searches for the assessments on NASA websites did not turn them up. NASA did not respond to requests for information. The National Oceanic and Atmospheric Administration, which coordinated the information in the assessments, did not respond to repeated inquiries. 'It's critical for decision makers across the country to know what the science in the National Climate Assessment is. That is the most reliable and well-reviewed source of information about climate that exists for the United States,' said University of Arizona climate scientist Kathy Jacobs, who coordinated the 2014 version of the report. 'It's a sad day for the United States if it is true that the National Climate Assessment is no longer available,' Jacobs said. 'This is evidence of serious tampering with the facts and with people's access to information, and it actually may increase the risk of people being harmed by climate-related impacts.' Harvard climate scientist John Holdren, who was President Obama's science advisor and whose office directed the assessments, said after the 2014 edition he visited governors, mayors and other local officials who told him how useful the 841-page report was. It helped them decide whether to raise roads, build seawalls and even move hospital generators from basements to roofs, he said. 'This is a government resource paid for by the taxpayer to provide the information that really is the primary source of information for any city, state or federal agency who's trying to prepare for the impacts of a changing climate,' said Texas Tech climate scientist Katharine Hayhoe, who has been a volunteer author for several editions of the report. Copies of past reports are still squirreled away in NOAA's library. NASA's open science data repository includes dead links to the assessment site. The most recent report, issued in 2023, included an interactive atlas that zoomed down to the county level. It found that climate change is affecting people's security, health and livelihoods in every corner of the country in different ways, with minority and Native American communities often disproportionately at risk. The 1990 Global Change Research Act requires a national climate assessment every four years and directs the president to establish an interagency United States Global Change Research Program. In the spring, the Trump administration told the volunteer authors of the next climate assessment that their services weren't needed and ended the contract with the private firm that helps coordinate the website and report. Days later, two of the biggest and most reputable Earth science societies announced they will pick up the slack and pursue a collection of reports in its place. Additionally, NOAA's main website was recently forwarded to a different NOAA website. Social media and blogs at NOAA and NASA about climate impacts for the general public were cut or eliminated. 'It's part of a horrifying big picture,' Holdren said. 'It's just an appalling whole demolition of science infrastructure.' The national assessments are more useful than international climate reports put out by the United Nations every seven or so years because they are more localized and more detailed, Hayhoe and Jacobs said. The national reports are not only peer reviewed by other scientists, but examined for accuracy by the National Academy of Sciences, federal agencies, the staff and the public. Hiding the reports would be censoring science, Jacobs said. And it's dangerous for the country, Hayhoe said, comparing it to steering a car on a curving road by only looking through the rearview mirror: 'And now, more than ever, we need to be looking ahead to do everything it takes to make it around that curve safely. It's like our windshield's being painted over.'

A giant glowing X and V will appear on the Moon's surface tonight
Two unusual formations will be visible on the Moon on Wednesday night, with a giant X and V appearing on the lunar surface. The rare celestial event will be observable for around four hours as the Moon approaches its first quarter moon phase, with both letters forming from sunlight hitting crater's on the Moon's surface at just the right angle. The lunar V appears when light illuminates the Ukert crater, while the lunar X is formed from the Bianchini, La Caille and Purbach craters. The lunar X and lunar V will only be observable through a telescope or binoculars pointed at the Moon's terminator – the line separating its light and dark side. This line is typically the most interesting part of the Moon for amateur astronomers to observe, as the shadows help to emphasize the topography. 'The lunar surface appears different nearer the terminator because there the Sun is nearer the horizon and therefore causes shadows to become increasingly long,' Nasa's website explains. 'These shadows make it easier for us to discern structure, giving us depth cues so that the two-dimensional image, when dominated by shadows, appears almost three-dimensional. 'Therefore, as the Moon fades from light to dark, shadows not only tell us the high from the low, but become noticeable for increasingly shorter structures. For example, many craters appear near the terminator because their height makes them easier to discern there.' The lunar X and lunar V phenomenon will appear from 4:41am on 3 July (11:41pm EDT on 2 July). The skies over the British Isles are expected to be mostly clear at this time, according to the latest weather forecast from the Met Office, though parts of Wales and the west coast of Ireland will be obscured by cloud. 'The Werner X does not leap out all at once but gradually appears over an interval of two hours and 20 minutes as the Sun rises on the spot,' astronomer David Chapman noted in a paper on the subject. 'Watching this is either excruciatingly slow (if you are in a hurry) or exceedingly quick (if you are attempting to sketch the scene). Remember, the Sun rises about 30 times slower on the Moon.'

HRT ‘can raise breast cancer risk' in younger women
Hormone replacement therapy can raise the risk of breast cancer in some younger women, a Lancet study suggests. An international team of researchers found the treatment was not linked to young onset breast cancer overall. But oestrogen plus progestin therapy appears to increase breast cancer risk by 10 per cent. Meanwhile, oestrogen hormone therapy use appeared to decrease breast cancer risk by 14 per cent. Hormone replacement therapy is a treatment used to help menopause symptoms. There are different types of HRT, which is used to treat menopause symptoms, available. They contain different hormones: some are oestrogen products; others contain progestogen and other types have both. These medicines can be taken or used in different ways and work by replacing the hormones oestrogen and progesterone, which can fall to lower levels as women approach the menopause. Most studies examining links between hormone therapy and breast cancer risk have been explored in older women. Previous work, which has focused on women who have already been through the menopause, suggest that oestrogen plus progestin hormone therapy is a risk factor for breast cancer. The researchers, led by academics from the National Institute of Environmental Health Sciences in the US, wanted to explore the risks among younger women on hormone therapy – who may take these drugs after gynaecological surgery or during perimenopause. The new meta-analysis published in the journal, Lancet Oncology, examined data drawn from previous studies of 459,476 women aged 16 to 54 years old. Some two per cent of this group (8,455) developed young-onset breast cancer, which means the disease was diagnosed before they were 55 years old. And 15 per cent of women involved in the study reported using hormone therapy, with oestrogen plus progestin hormone therapy and oestrogen being the most common types. 'Although the strength of these associations might vary by age at first use, duration of use, gynaecological surgery status, and other factors, unopposed oestrogen hormone therapy use appears to decrease breast cancer risk and oestrogen plus progestin therapy appears to increase breast cancer risk,' the authors wrote. 'The findings can be used to augment clinical recommendations for hormone therapy use in young women, for whom guidance was previously scarce.' Dr Kotryna Temcinaite, the head of research communications at Breast Cancer Now, said: 'These results are largely in line with what we already know about taking HRT for menopausal symptoms and its effects on breast cancer risk – for most people, the risk of developing breast cancer because of taking HRT is small and is outweighed by the benefits. 'Taking HRT is a very personal decision and, as such, it's vital that everyone has the information they need on the benefits and risks, discusses them with their GP or specialist team and is supported to make the choice that's right for them.'
