Congressionally mandated climate reports have disappeared from their federal websites
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 climate.gov 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.'

Scientists tracking ‘interstellar' object that has come to us from another solar system
Astronomers may have just discovered a new interstellar object passing through our solar system. The object, a celestial body from another star system, was discovered on Tuesday by the University of Hawaii's Asteroid Terrestrial-impact Last Alert System, or ATLAS, team. At this point, it remains unclear what the object may be or look like as it moves near Jupiter. Now, scientists are checking to confirm their findings. 'ESA's Planetary Defenders are observing the object, provisionally known as #A11pl3Z, right now using telescopes around the world,' the European Space Agency said in a social media post on Wednesday. The National Aeronautics and Space Administration told The Associated Press that it is monitoring the situation. David Rankin, of the University of Arizona's Catalina Sky Survey, said in posts on BlueSky that follow-up observations were made not long after the discovery. A precovery — observations from archival images in which the object was not originally discovered — from CalTech's Zwicky Transient Facility hinted at the presence of an interstellar object. 'After a few more precovery observations, and follow-ups, it became clear this object is on a hyperbolic trajectory through the solar system,' Rankin wrote. Since then, new observations have been 'rolling in,' helping astronomers to better determine its orbit. Rankin noted that the first known interstellar object to visit our solar system was 'Oumuamua, which was spotted in 2017. Up to one-quarter mile-long and 10 times as long as it is wide, its resembles a rocky cigar with a reddish hue. Its aspect ratio, which is greater than that of any asteroid or comet observed in our solar system to date, even led to speculation that it could be an alien spacecraft. Observations then suggested that it had been wandering through our Milky Way galaxy for hundreds of millions of years before its encounter with our star system, according to NASA. The second known object was Comet 2I/Borisov, found in 2019. It is the first confirmed interstellar comet, and was later captured by the Hubble Space Telescope. Scientists believe that many more such objects regularly pass by the Earth, with a number of them flying relatively near to us each year. However, many of them go undetected because they are hard to spot and it is difficult to know for sure where they have come from. Researchers hope to eventually learn more about them and even use them as evidence for distant star systems and planets. They also hope to find more of them in the years to come, thanks to new and more powerful telescopes, such as the recently switched-on Vera C Rubin Observatory.

NASA's skywatching tips for July include an ‘eagle'
NASA is back with its monthly roundup on what to look out for in the skies over the coming weeks. And there's plenty to enjoy. The planets take center stage this month, with July offering a great chance to view Mercury, Mars, Saturn, Venus, and Jupiter. You'll be able to see Mercury for a brief period following sunset during the first week of July. Cast your gaze very low in the west 30 to 45 minutes after sundown. Mercury sets within the hour after that, so be sure to carefully pinpoint it before it vanishes from view. Next up, Mars. The red planet will be visible for the first hour or two after it gets dark. 'You'll find it sinking lower in the sky each day and looking a bit dimmer over the course of the month, as our two planets' orbits carry them farther apart,' NASA says in its latest roundup video (top), adding that the crescent moon will appear right next to Mars on July 28. The space agency also notes that July marks the 60th anniversary of the first successful flyby of Mars, by NASA's Mariner 4 spacecraft. During the mission, Mariner 4 also became the first spacecraft to beam back photos of another planet. Saturn — the sixth planet from the sun and the second largest planet in our solar system — rises late in the evening this month, and by dawn appears high overhead to the south. Meanwhile, Venus — our brightest planet — will be shining brightly throughout the month, making it easy to spot. However, you'll have to wake up early as it's only viewable a couple of hours before sunrise, toward the east. Last but not least, Jupiter — the largest planet in our solar system — will be rising in the hour before sunrise and appearing a little higher with each passing day. NASA also points out that July and August is an excellent chance to view the constellation Aquila, also known as the eagle as its star pattern resembles an eagle in flight. 'This time of year, it soars high into the sky in the first half of the night,' NASA says. adding that to find it, first locate its brightest star, Altair. 'It's one of the three bright stars in the Summer Triangle, which is super easy to pick out during summer months in the Northern Hemisphere. Altair is the second brightest of the three, and sits at the southernmost corner of the triangle.' Check out the video for more details — including helpful images — on how to view Aquila and also the planets.

Look up! What's going on in the July night sky?
Eyes to the sky for the month of July to see the Buck Moon, two different meteor showers crisscrossing the night, and the waning phases of the Moon appearing near some of the brightest planets in the sky. Here is the Astronomical Guide for July 2025: July 2 — First Quarter Moon July 10-11 — Full Buck Moon July 12 — delta Aquariid meteor shower begins July 15-16 — Saturn near Gibbous Moon (after midnight) July 17 — Perseid meteor shower begins July 18 — Last Quarter Moon July 21 — Venus near Crescent Moon, Jupiter nearby (predawn) July 23 — Jupiter near Crescent Moon, Venus nearby (predawn) July 24 — New Moon July 28 — Mars near Crescent Moon (evening) July 28-29 — delta Aquariid Meteor Shower peaks The astronomical events for July 2025, including the phases of the Moon, planetary conjunctions, and meteor showers. (Scott Sutherland, moon graphics from NASA's Scientific Visualization Studio, conjunctions courtesy Stellarium) The Waxing Crescent Moon will be in the western sky during the evening hours on the first night of the month, with the First Quarter Moon rising on the second. We will see the Waxing Gibbous Moon from the 3rd through the 9th, with the Full Buck Moon — the first Full Moon of Summer 2025 — crossing the sky from the evening on the 10th through until the morning on the 11th. However, the Moon will appear full (over 99 per cent illuminated by the Sun) from just after midnight on the morning of the 10th through until the evening of the 11th. The Waning Gibbous Moon will shine in the sky from the 11th to the 16th. Look for it near Saturn in the hours after midnight on the night of the 15th to the 16th. The Last Quarter Moon rises on the 17th, with the Waning Crescent Moon visible in the eastern predawn sky each morning from the 18th to the 23th. See it pass by bright Venus on the 21st, then nestled between Venus and Jupiter on the 22nd, and finally passing Jupiter on the 23rd. The night of the 24th could be the best time to look for meteors (see below), as the New Moon gives us the darkest skies of the month. Then, once the Waxing Crescent Moon reappears in our evening skies, look for it near the planet Mars just above the western horizon after sunset on the 28th. DON'T MISS: When we hear about meteor showers, often only the peak of the event gets any solid mention. It's certainly understandable, since that is when the greatest number of meteors from that particular shower are visible to us. However, meteor showers are not limited to just one night. For the dozen or so notable ones we follow each year, the shortest lasts for around 4 days, while the longest goes on for over two months! During the month of July, we see the start of two different meteor showers, both of which are remarkable in some way. The first begins on the night of July 17. Appearing to streak out of the constellation Perseus, in the northeastern sky, this meteor shower is known as the Perseids, and it is one of the best of the entire year. Originating from a comet known as 109P/Swift-Tuttle, the Perseids typically deliver between 50-75 meteors per hour during the shower's mid-August peak. It also produces the greatest number of fireballs out of all the meteor showers of the year. Fireballs are meteors of exceptional brightness, many of which can be seen even through urban light pollution. While most Perseid meteors result from miniscule specks of space dust hitting the atmosphere, the fireballs are due to comet debris ranging from a grain of sand up to a pebble in size. The Perseids start off slowly in July. For the first week or so after the shower begins, we may see just a few meteors each hour, flashing out of the northeastern sky. However, by the end of the month, it typically is already producing around 15-20 meteors per hour. Even though that's still around two weeks before the Perseid's peak, that's still equivalent to the peak of a moderate meteor shower, like the April Lyrids! Just one night after the Perseids start, we encounter a second stream of debris in space, resulting in the Southern delta Aquariid meteor shower. While this one tends to put on a better display for those located in the southern hemisphere, skywatchers across Canada should still get a decent show out of it. As with the Perseids, the delta Aquariids start off at a rate of just one or two meteors per hour on the nights of the first week or so. During the last few nights of July, though, this meteor shower reaches its peak, with the rate jumping up to around 20 per hour. Overlapping with Perseids at that time, the sky could be filled with crisscrossing meteors at the end of the month. Astronomers aren't quite sure exactly which comet or asteroid the delta Aquariids come from, but right now, the most likely 'parent body' is an oddball comet called 96P/Machholz. Discovered in 1986, Comet Machholz has a strange orbit and chemical composition compared to other similar comets. One hypothesis for this is that it could be an alien comet from some distant star system that was ejected and then captured by the gravity of our Sun. Thus, each delta Aquariid meteor could represent a piece of some distant solar system burning up in our atmosphere! READ MORE: The summer constellations shine this month. In the south, Leo leads the way as the constellations cross the sky, with Virgo, Libra, Scorpius, Serpens/Ophiuchus, and Aquila in a loose lineup just after sunset. Higher up in the sky we will see Boötes, Hercules, and Cygnus. The constellations in the southern sky at midnight on July 15-16, 2025. (Stellarium) After midnight, Sagittarius, Capricornus, Aquarius, Pisces, and Cetus follow, with Taurus rising predawn and the "bow" of Orion poking up above the horizon just before sunrise. High up, Pegasus, Andromeda and Perseus swing around from the north. Meanwhile, if you are facing north, Pegasus, Andromeda, and Perseus will be near the northern horizon at the start of the night. Cygnus, Cepheus, Cassiopeia, and Camelopardalis ("The Camel") will be visible low in the evening sky, along with Lynx to the northwest. Ursa Major ("The Big Dipper"), Ursa Minor ("The Little Dipper"), and Draco will be circling the north celestial pole. The constellations in the northern sky at midnight on July 15-16, 2025. (Stellarium) After midnight, Auriga and Taurus will rise in the northeast, with Orion showing up before dawn.
