İstanbul Üniversitesi-Cerrahpaşa (İÜC) Cerrahpaşa Tıp Fakültesi Dahili Tıp Bilimleri Bölümü Çocuk Sağlığı ve Hastalıkları Ana Bilim Dalı Başkanı Prof. Dr. Haluk Çokuğraş, Çocuk Göğüs Hastalıkları, Çocuk Acil ve Çocuk Enfeksiyon Hastalıkları ana bilim dallarından öğretim üyeleriyle yaptığı bilgilendirme toplantısında, her sağlıklı çocuğun mevsimsel olarak hastalanabildiğini, okula giden çocukların bu enfeksiyonları daha fazla yaşayabildiğini ve yılda 6-8 kez solunum yolu enfeksiyonu geçirilebildiğini anlattı.
Son dönemde arka arkaya enfeksiyonlara yol açan bir salgın yaşandığını ancak bunun normal bir süreç olduğunu belirten Çokuğraş, "Bu sene influenza, grip çok yaygın. Onun dışında RSV (Respiratuvar Sinsitiyal Virüs), Adenovirüs gibi 200 civarında virüs var. Bunlar arka arkaya çocuklarda enfeksiyona yol açıyor. Hangi virüs hangi belirtiye yol açıyor bunu söylemek mümkün değil." bilgisini verdi.
Çokuğraş, virüslerin ortak belirtilerinin, öksürük, ateş, burun akıntısı, halsizlik, baş ağrısı, boğaz ağrısı olduğunu kaydetti.
"Acile 150 hasta geliyordu şimdi 400'lere yaklaşmaya başladı"
Acil serviste vakaların arttığına dikkati çeken Prof. Dr. Çokuğraş, "Normal koşullarda acil servisimize 150 hasta geliyordu şimdi bu sayı 400'lere yaklaşmaya başladı. Bu ailelere sorun yaratmakla kalmıyor bizler için de ciddi bir sorun haline geliyor. Çünkü kapasitemiz belli. Acil servis belli bir sayının üzerinde hastayla karşılaştığı zaman buna cevap verecek ne yeteri kadar doktor oluyor ne de yatak oluyor ve dışarıda kuyruklar oluşuyor. Biz çocuk hekimleri de ciddi bir şekilde bu salgından yorulduk." diye konuştu.
Çokuğraş, bazı bulaşıcı hastalıklara karşı aşı olmanın önleyici bir yöntem olduğunu vurgulayarak, şöyle devam etti:
"Kovid-19'da Türkiye'de 12 yaşın üzerindeki çocuklar için aşımız var, bir de influenza, gribe karşı bir aşımız var. 6 aylıktan itibaren çocukları aşılarsak yüzde 100 değilse bile yüzde 70-80 oranında korunma sağlıyoruz. En azından hastalık daha hafif geçiyor. Ama diğer virüslere karşı onlar için bir aşı maalesef yok. Onun için yapabileceğimiz şey, Kovid-19 pandemisinin başında yaptığımız şeyleri tekrarlamaktan ibaret. Mümkün olduğu kadar kalabalık yerlere girdiğimizde çocuklar için konuşuyorsak, okullarda maske takmak koruyucu bir önlem olabilir ya da sinema tiyatro gibi kalabalık kapalı alanlarda maske takmak bir çözüm olabilir."
Toplu bulunulan yerlerden kaçınmak gerektiğini belirten Çokuğraş, el yıkamanın da bu virüslerin bulaşması açısından önleyici bir tedbir olacağını söyledi.
"İki senedir pasif halde olan virüslerin hepsi aynı anda geldi"
Çocuk Göğüs Hastalıkları Bilim Dalı Öğretim Üyesi Doç. Dr. Ayşe Ayzıt Kılınç Sakallı, beslenme ve sıvı desteğine dikkat ederek, antibiyotik kullanımına gerek kalmadan viral enfeksiyonların üstesinden gelinebileceğini vurguladı.
Toplum olarak maske kullanmanın koruyucu önlem olduğunu belirten Sakallı, "Özellikle bebeklerde, altta yatan birtakım kronik hastalığı olanlarda, yaşlılarda, tansiyon, kalp, şeker hastalığı olanların biraz daha dikkatli davranması gerekiyor. Solunum yolu enfeksiyon semptomları olan kişilerin maske takmaları gerekirse diğer sağlıklı kişilerle aynı ortamda bulunmaması gerekiyor." önerisinde bulundu.
Çocuk Acil Bilim Dalı Öğretim Üyesi Uzman Dr. Sinem Oral, iki senedir pasif halde olan virüslerin hepsinin aynı anda geldiğine vurgu yaparak, özellikle ailelerin kendilerini korumaları gerektiğine dikkati çekti.
Oral, "Son iki senede o kadar iyi korunduk ki son iki yılda doğan çocukların çoğu gerçek bir enfeksiyonla tam anlamıyla karşılaşmadılar, o yüzden de vücutları daha antrenmansız. Özellikle 3 ayın altındaki bebeklerde ağır solunum yolu enfeksiyonları görüyoruz. Bu çocuklar hastalıkları bizlerden kapıyorlar o yüzden önce aileler olarak kendimizi korumayı öğrenmeliyiz ki çocuklar daha az hasta olsunlar. Pandeminin başındaki önlemlere o kadar katı olmasa da dönmemiz gerektiğini düşünüyorum." dedi.

“It’s true that both plants are not yet operating at the capacity we originally targeted,” said the Climeworks spokesperson.
<a href=https://tripscan.biz>трипскан</a>
“Like all transformative innovations, progress is iterative, and some steps may take longer than anticipated,” they said.
The company’s prospective third plant in Louisiana aims to remove 1 million tons of carbon a year by 2030, but it’s uncertain whether construction will proceed under the Trump administration.
A Department of Energy spokesperson said a department-wide review was underway “to ensure all activities follow the law, comply with applicable court orders and align with the Trump administration’s priorities.” The government has a mandate “to unleash ‘American Energy Dominance’,” they added.
Direct air capture’s success will also depend on companies’ willingness to buy carbon credits.

Currently companies are pretty free to “use the atmosphere as a waste dump,” said Holly Buck, assistant professor of environment and sustainability at the University at Buffalo. “This lack of regulation means there is not yet a strong business case for cleaning this waste up,” she told CNN.
Another criticism leveled at Climeworks is its failure to offset its own climate pollution. The carbon produced by its corporate activities, such as office space and travel, outweighs the carbon removed by its plants.
The company says its plants already remove more carbon than they produce and corporate emissions “will become irrelevant as the size of our plants scales up.”
Some, however, believe the challenges Climeworks face tell a broader story about direct air capture.
This should be a “wake-up call,” said Lili Fuhr, director of the fossil economy program at the Center for International Environmental Law. Climeworks’ problems are not “outliers,” she told CNN, “but reflect persistent technical and economic hurdles faced by the direct air capture industry worldwide.”
“The climate crisis demands real action, not speculative tech that overpromises and underdelivers.” she added.
Some of the Climeworks’ problems are “related to normal first-of-a-kind scaling challenges with emerging complex engineering projects,” Buck said.
But the technology has a steep path to becoming cheaper and more efficient, especially with US slashing funding for climate policies, she added. “This kind of policy instability and backtracking on contracts will be terrible for a range of technologies and innovations, not just direct air capture.”
Direct air capture is definitely feasible but its hard, said MIT’s Buck. Whether it succeeds will depend on a slew of factors including technological improvements and creating markets for carbon removals, he said.
“At this point in time, no one really knows how large a role direct air capture will play in the future.”

NASA scientists are in a state of anxious limbo after the Trump administration proposed a budget that would eliminate one of the United States’ top climate labs – the NASA Goddard Institute for Space Studies, or GISS – as a standalone entity.
<a href=https://kra34c.cc>kra34 cc</a>
In its place, it would move some of the lab’s functions into a broader environmental modeling effort across the agency.
Career specialists are now working remotely, awaiting details and even more unsure about their future at the lab after they were kicked out of their longtime home in New York City last week. Closing the lab for good could jeopardize its value and the country’s leadership role in global climate science, sources say.
“It’s an absolute sh*tshow,” one GISS scientist said under condition of anonymity because they were not authorized to speak to the media. “Morale at GISS has never been lower, and it feels for all of us that we are being abandoned by NASA leadership.”
“We are supposedly going to be integrated into this new virtual NASA modeling institute, but (we have) no idea what that will actually look like,” they said.
NASA is defending its budget proposal, with a nod toward the lab’s future.
“NASA’s GISS has a significant place in the history of space science and its work is critical for the Earth Science Division, particularly as the division looks to the future of its modeling work and capabilities,” NASA spokesperson Cheryl Warner said in a statement.
“Fundamental contributions in research and applications from GISS directly impact daily life by showing the Earth system connections that impact the air we breathe, our health, the food we grow, and the cities we live in,” Warner said.
GISS has a storied history in climate science on the global scale.
James Hansen, a former director, first called national attention to human-caused global warming at a Senate hearing during the hot summer of 1988. The lab, founded in 1961, is still known worldwide for its computer modeling of the planet that enable scientists to make projections for how climate change may affect global temperatures, precipitation, extreme weather events and other variables.

Study reveals how much energy AI uses to answer your questions
<a href=https://tripscan.biz>tripskan</a>
Whether it’s answering work emails or drafting wedding vows, generative artificial intelligence tools have become a trusty copilot in many people’s lives. But a growing body of research shows that for every problem AI solves, hidden environmental costs are racking up.
Each word in an AI prompt is broken down into clusters of numbers called “token IDs” and sent to massive data centers — some larger than football fields — powered by coal or natural gas plants. There, stacks of large computers generate responses through dozens of rapid calculations.
The whole process can take up to 10 times more energy to complete than a regular Google search, according to a frequently cited estimation by the Electric Power Research Institute.

So, for each prompt you give AI, what’s the damage? To find out, researchers in Germany tested 14 large language model (LLM) AI systems by asking them both free-response and multiple-choice questions. Complex questions produced up to six times more carbon dioxide emissions than questions with concise answers.
In addition, “smarter” LLMs with more reasoning abilities produced up to 50 times more carbon emissions than simpler systems to answer the same question, the study reported.
“This shows us the tradeoff between energy consumption and the accuracy of model performance,” said Maximilian Dauner, a doctoral student at Hochschule Munchen University of Applied Sciences and first author of the Frontiers in Communication study published Wednesday.
Typically, these smarter, more energy intensive LLMs have tens of billions more parameters — the biases used for processing token IDs — than smaller, more concise models.
“You can think of it like a neural network in the brain. The more neuron connections, the more thinking you can do to answer a question,” Dauner said.
What you can do to reduce your carbon footprint
Complex questions require more energy in part because of the lengthy explanations many AI models are trained to provide, Dauner said. If you ask an AI chatbot to solve an algebra question for you, it may take you through the steps it took to find the answer, he said.
The CO2 that is extracted…
The CO2 that is extracted from the water is run through a purification process that uses activated carbon in the form of charred coconut husks, and is then ready to be stored.
[url=https://tripscan.biz]tripscan[/url]
In a scaled up system, it would be fed into geological CO2 storage. Before the water is released, its acidity is restored to normal levels, making it ready to absorb more carbon dioxide from the air.
“This discharged water that now has very low carbon concentrations needs to refill it, so it’s just trying to suck CO2 from anywhere, and it sucks it from the atmosphere,” says Halloran. “A simple analogy is that we’re squeezing out a sponge and putting it back.”
While more tests are needed to understand the full potential of the technology, Halloran admits that it doesn’t “blow direct air capture out the water in terms of the energy costs,” and there are other challenges such as having to remove impurities from the water before releasing it, as well as the potential impact on ecosystems. But, he adds, all carbon capture technologies incur high costs in building plants and infrastructure, and using seawater has one clear advantage: It has a much higher concentration of carbon than air does, “so you should be able to really reduce the capital costs involved in building the plants.”

Mitigating impacts
One major concern with any system that captures carbon from seawater is the impact of the discharged water on marine ecosystems. Guy Hooper, a PhD researcher at the University of Exeter, who’s working on this issue at the SeaCURE site, says that low-carbon seawater is released in such small quantities that it is unlikely to have any effect on the marine environment, because it dilutes extremely quickly.
However, that doesn’t mean that SeaCURE is automatically safe. “To understand how a scaled-up version of SeaCURE might affect the marine environment, we have been conducting experiments to measure how marine organisms respond to low-carbon seawater,” he adds. “Initial results suggest that some marine organisms, such as plankton and mussels, may be affected when exposed to low-carbon seawater.”
To mitigate potential impacts, the seawater can be “pre-diluted” before releasing it into the marine environment, but Hooper warns that a SeaCURE system should not be deployed near any sensitive marine habitats.
There is rising interest in carbon capture from seawater — also known as Direct Ocean Capture or DOC — and several startups are operating in the field. Among them is Captura, a spin off from the California Institute of Technology that is working on a pilot project in Hawaii, and Amsterdam-based Brineworks, which says that its method is more cost-effective than air carbon capture.
According to Stuart Haszeldine, a professor of Carbon Capture and Storage at the University of Edinburgh, who’s not involved with SeaCURE, although the initiative appears to be more energy efficient than current air capture pilot tests, a full-scale system will require a supply of renewable energy and permanent storage of CO2 by compressing it to become a liquid and then injecting it into porous rocks deep underground.
He says the next challenge is for SeaCURE to scale up and “to operate for longer to prove it can capture millions of tons of CO2 each year.”
But he believes there is huge potential in recapturing carbon from ocean water. “Total carbon in seawater is about 50 times that in the atmosphere, and carbon can be resident in seawater for tens of thousands of years, causing acidification which damages the plankton and coral reef ecosystems. Removing carbon from the ocean is a giant task, but essential if the consequences of climate change are to be controlled,” he says.
A nuclear fusion power plant…
A nuclear fusion power plant prototype is already being built outside Boston. How long until unlimited clean energy is real?
<a href=https://vk.com/wall799627835_164>русское порно жесток</a>
In an unassuming industrial park 30 miles outside Boston, engineers are building a futuristic machine to replicate the energy of the stars. If all goes to plan, it could be the key to producing virtually unlimited, clean electricity in the United States in about a decade.
The donut-shaped machine Commonwealth Fusion Systems is assembling to generate this energy is simultaneously the hottest and coldest place in the entire solar system, according to the scientists who are building it.
It is inside that extreme environment in the so-called tokamak that they smash atoms together in 100-million-degree plasma. The nuclear fusion reaction is surrounded by a magnetic field more than 400,000 times more powerful than the Earth’s and chilled with cryogenic gases close to absolute zero.
The fusion reaction — forcing two atoms to merge — is what creates the energy of the sun. It is the exact opposite of what the world knows now as “nuclear power” — a fission reaction that splits atoms.
Nuclear fusion has far greater energy potential, with none of the safety concerns around radioactive waste.
SPARC is the tokamak Commonwealth says could forever change how the world gets its energy, generating 10 million times more than coal or natural gas while producing no planet-warming pollution. Fuel for fusion is abundant, derived from deuterium, found in seawater, and tritium extracted from lithium. And unlike nuclear fission, there is no atomic waste involved.
The biggest hurdle is building a machine powerful and precise enough to harness the molten, hard-to-tame plasma, while also overcoming the net-energy issue – getting more energy out than you put into it.
“Basically, what everybody expects is when we build the next machine, we expect it to be a net-energy machine,” said Andrew Holland, CEO of the Fusion Industry Association, a trade group representing fusion companies around the globe. “The question is, how fast can you build that machine?”
Commonwealth’s timeline is audacious: With over $2 billion raised in private capital, its goal is to build the world’s first fusion-fueled power plant by the early 2030s in Virginia.
“It’s like a race with the planet,” said Brandon Sorbom, Commonwealth’s chief science officer. Commonwealth is racing to find a solution for global warming, Sorbom said, but it’s also trying to keep up with new power-hungry technologies like artificial intelligence. “This factory here is a 24/7 factory,” he said. “We’re acutely aware of it every minute of every hour of every day.”

‘Extraordinary rainstorm’ floods Nebraska city, triggers water rescues
<a href=https://tripscan.biz>трипскан</a>
An entire June’s worth of rain fell in just a few hours over Grand Island, Nebraska, Wednesday night, triggering life-threatening flash flooding that inundated neighborhoods, stranded motorists and forced water rescues.
Crews have responded to dozens of calls to assist motorists stuck in flooded roads since torrential rain began Wednesday night, according to Spencer Schubert, the city’s communications manager. The flooding has also displaced an unspecified number of residents from their homes.

“At this time we have no injuries to report,” Schubert said early Thursday morning, noting some rescues were ongoing.
Torrential rain caused sewers to back up into several homes and sent floodwater running into basements, according to a Thursday news release from the city. Some affected residents took shelter at local hotels or with friends and family.
“This was an extraordinary rainstorm and is very similar to the historic rains seen in the 2005 floods,” Jon Rosenlund, the city’s emergency director said. “We will be actively monitoring rivers, creeks and other drainage areas over the next few days for future flooding issues.”
Flooding in 2005 turned streets into rivers in Grand Island. At one point, the city tore up a major road to open up a channel to drain flooding away from homes, CNN affiliate KHGI reported.
The central Nebraskan city is home to around 53,000 people and is about 130 miles southwest of Omaha. The rain came to an end around sunrise Thursday, but the danger remains, with a flood warning in effect until 7 p.m. CDT.

(environmental) cost of generating a response, people would maybe start thinking, ‘Is it really necessary to turn myself into an action figure just because I’m bored?’ Or ‘do I have to tell ChatGPT jokes because I have nothing to do?’” Dauner said.
Additionally, as more companies push to add generative AI tools to their systems, people may not have much choice how or when they use the technology, Luccioni said.
“We don’t need generative AI in web search. Nobody asked for AI chatbots in (messaging apps) or on social media,” Luccioni said. “This race to stuff them into every single existing technology is truly infuriating, since it comes with real consequences to our planet.”

With less available information about AI’s resource usage, consumers have less choice, Ren said, adding that regulatory pressures for more transparency are unlikely to the United States anytime soon. Instead, the best hope for more energy-efficient AI may lie in the cost efficacy of using less energy.
“Overall, I’m still positive about (the future). There are many software engineers working hard to improve resource efficiency,” Ren said. “Other industries consume a lot of energy too, but it’s not a reason to suggest AI’s environmental impact is not a problem. We should definitely pay attention.”

These preppers have ‘go bags,’ guns and a fear of global disaster. They’re also left-wing
<a href=https://tripscan.biz>tripscan top</a>
The day after President Donald Trump was elected in 2016, Eric Shonkwiler looked at his hiking bag to figure out what supplies he had. “I began to look at that as a resource for escape, should that need to happen,” he said.
He didn’t have the terminology for it at the time, but this backpack was his “bug-out bag” — essential supplies for short-term survival. It marked the start of his journey into prepping. In his Ohio home, which he shares with his wife and a Pomeranian dog, Rosemary, he now has a six-month supply of food and water, a couple of firearms and a brood of chickens. “Resources to bridge the gap across a disaster,” he said.

Margaret Killjoy’s entry point was a bleak warning in 2016 from a scientist friend, who told her climate change was pushing the global food system closer than ever to collapse. Killjoy started collecting food, water and generators. She bought a gun and learned how to use it. She started a prepping podcast, Live Like the World is Dying, and grew a community.
Prepping has long been dominated by those on the political right. The classic stereotype, albeit not always accurate, is of the lone wolf with a basement full of Spam, a wall full of guns, and a mind full of conspiracy theories.
Shonkwiler and Killjoy belong to a much smaller part of the subculture: They are left-wing preppers. This group is also preparing for a doom-filled future, and many also have guns, but they say their prepping emphasizes community and mutual aid over bunkers and isolationism.
In an era of barreling crises — from wars to climate change — some say prepping is becoming increasingly appealing to those on the left.
The roots of modern-day prepping in the United States go back to the 1950s, when fears of nuclear war reached a fever pitch.
The 1970s saw the emergence of the survivalist movement, which dwindled in the 1990s as it became increasingly associated with an extreme-right subculture steeped in racist ideology.
A third wave followed in the early 2000s, when the term “prepper” began to be adopted more widely, said Michael Mills, a social scientist at Anglia Ruskin University, who specializes in survivalism and doomsday prepping cultures. Numbers swelled following big disasters such as 9/11, Hurricane Katrina in 2005 and the 2008 financial crisis.
A watershed moment for right-wing preppers was the election of Barack Obama in 2008, Mills said. For those on the left, it was Trump’s 2016 election.
Preppers of all political stripes are usually motivated by a “foggy cloud of fear” rather than a belief in one specific doomsday scenario playing out, Mills said. Broad anxieties tend to swirl around the possibility of economic crises, pandemics, natural disasters, war and terrorism.
“We’ve hit every one of those” since the start of this century, said Anna Maria Bounds, a sociology professor at Queens College, who has written a book about New York’s prepper subculture. These events have solidified many preppers’ fears that, in times of crisis, the government would be “overwhelmed, under-prepared and unwilling to help,” she said.

Two huge plants in Iceland operate like giant vacuum cleaners, sucking in air and stripping out planet-heating carbon pollution. This much-hyped climate technology is called direct air capture, and the company behind these plants, Switzerland-based Climeworks, is perhaps its most high-profile proponent.
But a year after opening a huge new facility, Climeworks is straining against strong headwinds. The company announced this month it would lay off around 20% of its workforce, blaming economic uncertainties and shifting climate policy priorities.

“We’ve always known this journey would be demanding. Today, we find ourselves navigating a challenging time,” Climeworks’ CEOs Christoph Gebald and Jan Wurzbacher said in a statement.
This is particularly true of its US ambitions. A new direct air capture plant planned for Louisiana, which received $50 million in funding from the Biden administration, hangs in the balance as President Donald Trump slashes climate funding.
Climeworks also faces mounting criticism for operating at only a fraction of its maximum capacity, and for failing to remove more climate pollution than it emits.
The company says these are teething pains inherent in setting up a new industry from scratch and that it has entered a new phase of global scale up. “The overall trajectory will be positive as we continue to define the technology,” said a Climeworks spokesperson.
For critics, however, these headwinds are evidence direct air capture is an expensive, shiny distraction from effective climate action.

Despite prepping’s reputation as a form of doomerism, many left-wing preppers say they are not devoid of hope.

Shonkwiler believes there will be an opportunity to create something new in the aftermath of a crisis. “It begins with preparedness and it ends with a better world,” he said.
Some also say there’s less tension between left- and right-wing preppers than people might expect. Bounds, the sociology professor, said very conservative preppers she met during her research contacted her during the Covid-19 pandemic to offer help.

There is a natural human solidarity that emerges amid disaster, Killjoy said. She recalls a cashier giving her a deep discount on supplies she was buying to take to Asheville post-Helene. “I have every reason to believe that that man is right-wing, and I do think that there is a transcending of political differences that happens in times of crisis,” she said.
As terrifying events pile up, from the wars in Ukraine and the Middle East to deadly extreme weather, it’s hard to escape the sense we live in a time of rolling existential crises — often a hair’s breadth from global disaster.
People are increasingly beginning to wonder whether their views on preppers have been misconceived, Mills said. “There is a bigger question floating in the air, which is: Are preppers crazy, or is everyone else?”
Killjoy has seen a huge change over the last five years in people’s openness to prepping. Those who used to make fun of her for her “go bag” are now asking for advice.
It’s not necessarily the start of a prepping boom, she said. “I think it is about more and more people adopting preparedness and prepper things into a normal life.”
Evidence already points this way. Americans stockpiled goods in advance of Trump’s tariffs and online sales of contraceptives skyrocketed in the wake of his election, amid concerns he would reduce access. Shows like “The Walking Dead,” meanwhile, have thrust the idea of prepping into popular culture and big box stores now sell prepping equipment and meal kits.
People are hungry to learn about preparedness, said Shonkwiler. “They have the understanding that the world as we knew it, and counted on it, is beginning to cease to be. … What we need to be doing now is figuring out how we can survive in the world that we’ve created.”
Many left-wing preppers also…
Many left-wing preppers also have guns.
<a href=https://tripscan.biz>tripskan</a>
Killjoy is open about the fact she owns firearms but calls it one of the least important aspects of her prepping. She lives in rural Appalachia and, as a transgender woman, says the way she’s treated has changed dramatically since Trump’s first election. For those on the left, guns are “for community and self-defense,” she said.
Left-wing preppers consistently say the biggest difference between them and their right-wing peers is the rejection of “bunker mentality” — the idea of filling a bunker with beans, rice, guns and ammo and expecting to be able to survive the apocalypse alone.
Shonkwiler gives an example of a right-wing guy with a rifle on his back, who falls down the stairs and breaks a leg. If he doesn’t have medical training and a community to help, “he’s going to die before he gets to enjoy all his freeze-dried food.”
“People are our greatest asset,” Killjoy said. When Hurricane Helene carved a path of destruction through Asheville, North Carolina in 2024, Killjoy, who used to live in the city, loaded her truck with food and generators and drove there to help.

Inshirah Overton also subscribes to the idea of community. The attorney, who came to prepping after enduring Hurricane Irene in 2011, owns a half-acre plot of land in New Jersey where she grows food and has beehives.
She stores fruit, vegetables and honey but also gives them to friends and neighbors. “My plan is to create a community of people who have a vested interest in this garden,” she said.
At one point, Overton toyed with the idea of buying a “bug-out” property in Vermont, somewhere to escape to, but desire for community for her and her two daughters stopped her. In Vermont, “no one knows me and I’m just a random Black lady, and they’ll be like: ‘Oh, OK, right, sure. You live here? Sure. Here’s the barrel of my shotgun. Turn around.’”
This focus on community may stem in part from left-wing preppers’ growing fears around the climate crisis, predicted to usher in far-reaching ecological, social and economic breakdown. It cannot be escaped by retreating to a bunker for a few weeks.
As Trump guts weather agencies, pledges to unwind the Federal Emergency Management Administration and slashes climate funding — all while promising to unleash the fossil fuel industry — climate concerns are only coming into sharper focus.
They’re top of mind for Brekke Wagoner, the creator and host of the Sustainable Prepping YouTube channel, who lives in North Carolina with her four children. She fears increasingly deadly summer heat and the “once-in-a-lifetime” storms that keep coming. Climate change “is just undeniable,” she said.
Her prepping journey started during Trump’s first term. She was living in California and filled with fear that in the event of a big natural disaster, the federal government would simply not be there.
Her house now contains a week’s worth of water, long-term food supplies, flashlights, backup batteries and a solar generator. “My goal is for our family to have all of our needs cared for,” she said, so in an emergency, whatever help is available can go to others.
“You can have a preparedness plan that doesn’t involve a bunker and giving up on civilization,” she said.

‘Like wildfires underwater’: Worst summer on record for Great Barrier Reef as coral die-off sweeps planet
<a href=https://tripscan.biz>tripskan</a>
Great Barrier Reef, Australia
CNN
—
As the early-morning sun rises over the Great Barrier Reef, its light pierces the turquoise waters of a shallow lagoon, bringing more than a dozen turtles to life.
These waters that surround Lady Elliot Island, off the eastern coast of Australia, provide some of the most spectacular snorkeling in the world — but they are also on the front line of the climate crisis, as one of the first places to suffer a mass coral bleaching event that has now spread across the world.
https://tripscan.biz

The Great Barrier Reef just experienced its worst summer on record, and the US-based National Oceanic and Atmospheric Administration (NOAA) announced last month that the world is undergoing a rare global mass coral bleaching event — the fourth since the late 1990s — impacting at least 53 countries.
The corals are casualties of surging global temperatures which have smashed historical records in the past year — caused mainly by fossil fuels driving up carbon emissions and accelerated by the El Nino weather pattern, which heats ocean temperatures in this part of the world.
CNN witnessed bleaching on the Great Barrier Reef in mid-February, on five different reefs spanning the northern and southern parts of the 2,300-kilometer (1,400-mile) ecosystem.
“What is happening now in our oceans is like wildfires underwater,” said Kate Quigley, principal research scientist at Australia’s Minderoo Foundation. “We’re going to have so much warming that we’re going to get to a tipping point, and we won’t be able to come back from that.”

Bleaching occurs when marine heatwaves put corals under stress, causing them to expel algae from their tissue, draining their color. Corals can recover from bleaching if the temperatures return to normal, but they will perish if the water stays warmer than usual.
“It’s a die-off,” said Professor Ove Hoegh-Guldberg, a climate scientist at the University of Queensland in Australia and chief scientist at The Great Barrier Reef Foundation. “The temperatures got so warm, they’re off the charts … they never occurred before at this sort of level.”
The destruction of marine ecosystems would deliver an effective death sentence for around a quarter of all species that depend on reefs for survival — and threaten an estimated billion people who rely on reef fish for their food and livelihoods. Reefs also provide vital protection for coastlines, reducing the impact of floods, cyclones and sea level rise.
“Humanity is being threatened at a rate by which I’m not sure we really understand,” Hoegh-Guldberg said.
“We’re asking everyone to…
“We’re asking everyone to take it slow, avoid driving through standing water, and use alternate routes when possible,” Rosenlund urged.

Rainfall in Grand Island began Wednesday afternoon but the intensity picked up quickly after dark, falling at more than an inch per hour at times.
A total of 6.41 inches of rain fell by midnight, which made it the rainiest June day and the second rainiest day of any month in the city’s 130-year history of weather records.
The National Weather Service issued a flash flood emergency — the most severe form of flood warning — at 11:45 p.m. CDT Wednesday for Grand Island that continued for several hours into Thursday morning, continuously warning of “extensive flash flooding.”

Multiple rounds of heavy storms tracked over the area late Wednesday into early Thursday morning and ultimately dumped record amounts of rainfall. A level 2-of-4 risk of flooding rainfall was in place for Grand Island at the time, according to the Weather Prediction Center.
More than a month’s worth of rain – nearly 4.5 inches – fell in only three hours between 10 p.m. CDT Wednesday and 1 a.m. CDT Thursday. Rainfall of this intensity would only be expected around once in 100 years, according to National Oceanic and Atmospheric Administration data.
Climate change is making heavy rainfall events heavier. As the world warms due to fossil fuel pollution, a warmer atmosphere is able to soak up more moisture like a sponge, only to wring it out in heavier bursts of rain.
Hourly rainfall rates have intensified in nearly 90% of large US cities since 1970, a recent study found.
“AI expends a lot of energy…
“AI expends a lot of energy being polite, especially if the user is polite, saying ‘please’ and ‘thank you,’”
<a href=https://tripscan.biz>tripscan войти</a>
Dauner explained. “But this just makes their responses even longer, expending more energy to generate each word.”
For this reason, Dauner suggests users be more straightforward when communicating with AI models. Specify the length of the answer you want and limit it to one or two sentences, or say you don’t need an explanation at all.
Most important, Dauner’s study highlights that not all AI models are created equally, said Sasha Luccioni, the climate lead at AI company Hugging Face, in an email. Users looking to reduce their carbon footprint can be more intentional about which model they chose for which task.
“Task-specific models are often much smaller and more efficient, and just as good at any context-specific task,” Luccioni explained.

If you are a software engineer who solves complex coding problems every day, an AI model suited for coding may be necessary. But for the average high school student who wants help with homework, relying on powerful AI tools is like using a nuclear-powered digital calculator.
Even within the same AI company, different model offerings can vary in their reasoning power, so research what capabilities best suit your needs, Dauner said.
When possible, Luccioni recommends going back to basic sources — online encyclopedias and phone calculators — to accomplish simple tasks.
Why it’s hard to measure AI’s environmental impact
Putting a number on the environmental impact of AI has proved challenging.
The study noted that energy consumption can vary based on the user’s proximity to local energy grids and the hardware used to run AI models.
That’s partly why the researchers chose to represent carbon emissions within a range, Dauner said.
Furthermore, many AI companies don’t share information about their energy consumption — or details like server size or optimization techniques that could help researchers estimate energy consumption, said Shaolei Ren, an associate professor of electrical and computer engineering at the University of California, Riverside who studies AI’s water consumption.
“You can’t really say AI consumes this much energy or water on average — that’s just not meaningful. We need to look at each individual model and then (examine what it uses) for each task,” Ren said.
One way AI companies could be more transparent is by disclosing the amount of carbon emissions associated with each prompt, Dauner suggested.

Deep below the surface of…
Deep below the surface of the ground in one of the driest parts of the country, there is a looming problem: The water is running out — but not the kind that fills lakes, streams and reservoirs.
<a href=https://kra34c.cc>kraken</a>
The amount of groundwater that has been pumped out of the Colorado River Basin since 2003 is enough to fill Lake Mead, researchers report in a study published earlier this week. Most of that water was used to irrigate fields of alfalfa and vegetables grown in the desert Southwest.
No one knows exactly how much is left, but the study, published in the journal Geophysical Research Letters, shows an alarming rate of withdrawal of a vital water source for a region that could also see its supply of Colorado River water shrink.
“We’re using it faster and faster,” said Jay Famiglietti, an Arizona State University professor and the study’s senior author.
In the past two decades, groundwater basins – or large, underground aquifers – lost more than twice the amount of water that was taken out of major surface reservoirs, Famiglietti’s team found, like Mead and Lake Powell, which themselves have seen water levels crash.
The Arizona State University research team measured more than two decades of NASA satellite observations and used land modeling to trace how groundwater tables in the Colorado River basin were dwindling. The team focused mostly on Arizona, a state that is particularly vulnerable to future cutbacks on the Colorado River.
Groundwater makes up about 35% of the total water supply for Arizona, said Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University, who was not directly involved in the study.
The study found groundwater tables in the Lower Colorado River basin, and Arizona in particular, have declined significantly in the last decade. The problem is especially pronounced in Arizona’s rural areas, many of which don’t have groundwater regulations, and little backup supply from rivers. With wells in rural Arizona increasingly running dry, farmers and homeowners now drill thousands of feet into the ground to access water.
Scientists don’t know exactly how much groundwater is left in Arizona, Famiglietti added, but the signs are troubling.
“We have seen dry stream beds for decades,” he said. “That’s an indication that the connection between groundwater and rivers has been lost.”

Climeworks, which launched…
Climeworks, which launched in 2009, is among around 140 direct air capture companies globally, but is one of the most high-profile and best funded.
<a href=https://tripscan.biz>tripscan top</a>
In 2021, it opened its Orca plant in Iceland, followed in 2024 by a second called Mammoth. These facilities suck in air and extract carbon using chemicals in a process powered by clean, geothermal energy.
The carbon can then be reused or injected deep underground where it will be naturally transformed into stone, locking it up permanently. Climeworks makes its money by selling credits to companies to offset their own climate pollution.
The appeal of direct air capture is clear; to keep global warming from rising to even more catastrophic levels means drastically cutting back on planet-heating fossil fuels. But many scientists say the world will also need to remove some of the carbon pollution already in the atmosphere. This can be done naturally, for example through tree planting, or with technology like direct air capture.
https://tripscan.biz

The advantage of direct air capture is that carbon is removed from the air immediately and “can be measured directly and accurately,” said Howard Herzog, senior research engineer at the MIT Energy Initiative.
But there are big challenges, he told CNN. The concentration of carbon dioxide in the atmosphere has been shooting upward, but still only makes up about 0.04%. Herzog compares removing carbon directly from the air to needing to find 10 red marbles in a jar of 25,000 marbles of which 24,990 are blue.
This makes the process energy-intensive and expensive. The technology also takes time to scale.
Climeworks hasn’t come anywhere close to the full capacity of its plants. Orca can remove a maximum of 4,000 tons of carbon a year, but it has never captured more than 1,700 tons in a year since it opened in 2021. The company says single months have seen a capture rate much closer to the maximum.
The company’s Mammoth plant has a maximum capacity of 36,000 tons a year but since it opened last year it has removed a total of 805 tons, a figure which goes down to 121 tons when taking into account the carbon produced building and running the plants.
