Yoğun bakımdaki başarının sırrı: Fedakârlık

medikritik Sa, 28/04/2020 - 07:04

Hastanelerde yoğun bakım ünitesi sayısı arttı. Diğer servislerden hemşireler yoğun bakımda hizmet vermeye başladı. Deneyimli hemşire oranı yüzde 25’e düştü. Deneyimli hemşireler, zamanı unuttu. Yoğun bakım hemşireleri meslektaşlarına rehberlik için çalışma saatlerinin ötesine geçti.

Covid-19 salgınında pandemi hastaneleri, mevcut yoğun bakım ünitelerine yenilerini ekledi. Mevcut sağlık personeli yetersiz kalınca diğer servislerden yoğun bakım ünitelerine takviye yapıldı. Türk Yoğun Bakım Hemşireleri Derneği’nin raporuna göre, yoğun bakımlardaki deneyimli yoğun bakım hemşiresi oranı yüzde 25’e düştü. Derneğin başkanı Ebru Kıraner, deneyimli hemşirelerin rehberlik etmek için mesai saatlerini uzattıklarını belirterek, "Türkiye'nin yoğun bakımdaki başarısında sağlık personelinin üstün gayretinin payı var. Deneyimli hemşireler, hastalarını yalnız bırakmamak için mesai saatinin dışında da saatlerce çalışıyor" dedi. 

HEMŞİRELERİN YARISININ YOĞUN BAKIM EĞİTİMİ YOK

Yoğun bakım, hastanelerin en hassas alanı. Yoğun bakım hemşireleri, temel hemşirelik eğitiminin yanı sıra bir de yoğun bakım hemşireliği için eğitim alıyorlar. Bu eğitimi almak da yetmiyor. Yoğun bakım hemşireliği deneyim gerektiriyor. Pek çok ülke yoğun bakım hemşiresi sıfatını beş yıllık deneyimin ardından veriyor. Yoğun Bakım Hemşireleri Derneği’nin raporunda salgın döneminde deneyimli yoğun bakım hemşirelerinin ünitedeki oranının yüzde 25’e düştüğü belirtildi. Dernek Başkanı Ebru Kıraner, yoğun bakım hemşirelerinin çok özel bir eğitimden geçtiğini anlattı: “Lisans mezunları yoğun bakımlarda çalışmak için Sağlık Bakanlığı’nın sertifika programına katılıyor. Yoğun bakımlarda çalışan hemşirelerin yaklaşık yarısının sertifikası yok. Dünyada bu eğitimle ilgili öneri bin 200 saatin altına düşmemesi. Türkiye’deki koşullarda bu eğitim 240 saat. Eğitime katılanlar bir sınava giriyorlar ve kazanmaları halinde sertifika hakkı elde ediyorlar. Sağlık Bakanlığı 2019 bitmeden bütün hemşirelerin bu sertifikaya sahip olmasını hedefledi ancak bu hedef gerçekleşmedi. Hemşireler bu programda, yoğun bakımda kullanılan solunum cihazı, karaciğer destek, böbrek destek cihazlarıyla ilgili ve normal hastane servislerinde olmayan yüksek riskli ilaçların kullanımıyla ilgili eğitim alırlar. Kendini hiç ifade edemeyen, bütün ihtiyaçlarının hemşireler tarafından karşılandığı hastalardan söz ediyoruz. Sonuç olarak temel hemşirelik eğitiminin üstüne kritik hastaya nasıl bakılır eğitimi de yoğun bakım için gerekiyor.”

TEMEL İHTİYAÇLAR İÇİN BİLE ZAMAN YOK

Salgın döneminde hemşireler, eğitim almaksızın yoğun bakım ünitelerinde görevlendirildi. Ebru Kıraner, bu hemşirelerin desteğe ihtiyacı olduğunu söyledi. “Yetkin hemşireler, diğer servislerden yoğun bakıma gelen meslektaşları için de çaba harcamak zorunda. 8 hastalı bir ünitede bir tek deneyimli hemşire var. Bu hemşire, yemek, tuvalet gibi insani ihtiyaçlarını karşılayamayacak durumda. Çünkü, yoğun bakım şartlarında her an ani ve acil bir durum gelişebilir. Deneyimsiz hemşire, cihazdan alarm sesi geldiğinde doğru olanı yaptığını sanarak aslında hata yapabilir.”

'TEMELİMİZ SAĞLAM'

Deneyimli yoğun bakım hemşireleri çözüm için fedakarlığa hazır. Derneğin raporunda “Başka kliniklerden görevlendirilen hemşirelerin en az 40 saatlik süre ile yoğun bakım ünitelerine oryantasyonları sağlandıktan sonra, ‘ünitede yeterli sayıda deneyimli/rehber hemşire varsa’ deneyimli/rehber yoğun bakım hemşirelerine esnek mesai uygulamasının yapılmasını öneriyoruz” ifadesi yer aldı. Ebru Kıraner, yoğun bakım hemşireliğinin temelinde fedakarlık kültürünün olduğuna dikkat çekti. “Yıllardır böyle ciddi sorunlarla bu mesleği sürdürüyoruz. İhtiyacı olan insanların iyileştiğini görmekten başka maddi ve manevi hiçbir getirisi yok. 15-20 yıldır bu yalnızca bu motivasyonla çalışan hemşireler var. O temel çok sağlam. Esnek çalışma sadece hemşireler için değil hasta güvenliği açısından da riskleri daha aza indirebilir. Ama bu kadar sınırlı sayıda deneyimli hemşire ile bunun çok da mümkün olamayacağını biliyoruz. Dünya Yoğun Bakım Hemşireleri Federasyonu’nun hazırladığı rehberde onların da aynı sorumları yaşadığını gördük.”

'SAAT KAVRAMI YOK'

Kıraner’e “Yoğun bakımlarda bunca sorun Türkiye’nin başarısının nereden kaynaklanıyor?” diye sorduk. “Bu sonuç deneyimli yoğun bakım hemşirelerinin üstün gayretiyle alınıyor. Haftada 40 saat çalışması gereken deneyimli hemşireler 48 saat, 56 saat çalıştılar. Yoğun bakım bir ekip işi. Bugüne kadar da bütün yokluklara, sıkıntılara rağmen dünyadaki pek çok ülkeden iyi iş çıkarıyorduk. İnsanlar aynı kültüre sahip çıktılar. Başka kliniklerden gelen hemşirelere de rehberlik için büyük gayret gösterdiler. Saat kavramı yok oldu.”

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>kra34 cc</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.”

UK project trials carbon capture at sea to help tackle climate change
<a href=https://tripscan.biz>tripskan</a&gt;
The world is betting heavily on carbon capture — a term that refers to various techniques to stop carbon pollution from being released during industrial processes, or removing existing carbon from the atmosphere, to then lock it up permanently.

The practice is not free of controversy, with some arguing that carbon capture is expensive, unproven and can serve as a distraction from actually reducing carbon emissions. But it is a fast-growing reality: there are at least 628 carbon capture and storage projects in the pipeline around the world, with a 60% year-on-year increase, according to the latest report from the Global CCS (Carbon Capture and Storage) Institute. The market size was just over $3.5 billion in 2024, but is projected to grow to $14.5 billion by 2032, according to Fortune Business Insights.
https://tripscan.biz
трипскан вход
Perhaps the most ambitious — and the most expensive — type of carbon capture involves removing carbon dioxide (CO2) directly from the air, although there are just a few such facilities currently in operation worldwide. Some scientists believe that a better option would be to capture carbon from seawater rather than air, because the ocean is the planet’s largest carbon sink, absorbing 25% of all carbon dioxide emissions.

In the UK, where the government in 2023 announced up to ?20 billion ($26.7 billion) in funding to support carbon capture, one such project has taken shape near the English Channel. Called SeaCURE, it aims to find out if sea carbon capture actually works, and if it can be competitive with its air counterpart.

“The reason why sea water holds so much carbon is that when you put CO2 into the water, 99% of it becomes other forms of dissolved carbon that don’t exchange with the atmosphere,” says Paul Halloran, a professor of Ocean and Climate Science at the University of Exeter, who leads the SeaCURE team.

“But it also means it’s very straightforward to take that carbon out of the water.”

Pilot plant
SeaCURE started building a pilot plant about a year ago, at the Weymouth Sea Life Centre on the southern coast of England. Operational for the past few months, it is designed to process 3,000 liters of seawater per minute and remove an estimated 100 tons of CO2 per year.

“We wanted to test the technology in the real environment with real sea water, to identify what problems you hit,” says Halloran, adding that working at a large public aquarium helps because it already has infrastructure to extract seawater and then discharge it back into the ocean.

The carbon that is naturally dissolved in the seawater can be easily converted to CO2 by slightly increasing the acidity of the water. To make it come out, the water is trickled over a large surface area with air blowing over it. “In that process, we can constrict over 90% of the carbon out of that water,” Halloran says.

MichaelPrats (doğrulanmamış) Cu, 27/06/2025 - 14:48

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.
<a href=https://tripscan.biz>трипскан вход</a>
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.

This company says its technology can help save the world. It’s now cutting 20% of its staff as Trump slashes climate funding
<a href=https://trip-scan.top>трипскан сайт</a>
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.

These preppers have ‘go bags,’ guns and a fear of global disaster. They’re also left-wing
<a href=https://tripscan.biz>трип скан</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.

(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.”

Many left-wing preppers also have guns.
<a href=https://tripscan.biz>трипскан вход</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.

‘Extraordinary rainstorm’ floods Nebraska city, triggers water rescues
<a href=https://tripscan.biz>трипскан вход</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.
https://tripscan.biz

“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.

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.”

“It’s true that both plants are not yet operating at the capacity we originally targeted,” said the Climeworks spokesperson.

“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.”

‘Like wildfires underwater’: Worst summer on record for Great Barrier Reef as coral die-off sweeps planet
<a href=https://tripscan.biz>трипскан сайт</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.

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 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.
