A liquid nitrogen leak at a poultry plant northeast of Atlanta killed six workers and sent 11 more to the hospital Thursday.

First we just thought there was something wrong with the freezer, then they started saying get out," Fareed said. "I just saw the fog and when I couldn't see down the steps, I turned around. But I didn't feel anything."

Liquid nitrogen is colorless, odorless and extremely cold. It can cause serious damage and quick death with no warning. The gas can cause extensive tissue damage or burns. Inhaling large amounts of nitrogen can cause dizziness, nausea, vomiting, loss of consciousness and death.

The electric light, one of the everyday conveniences that most affects our lives, was not “invented” in the traditional sense in 1879 by Thomas Alva Edison, although he could be said to have created the first commercially practical incandescent light.

Edison is often credited with the invention because his version was able to outstrip the earlier versions because of a combination of three factors: an effective incandescent material, a higher vacuum than others were able to achieve and a high resistance that made power distribution from a centralized source economically viable.

In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp.

Each year we spew more than 100 times as much CO2 into the air as volcanoes do, and we’re currently overseeing the biggest disruption to the planet’s nitrogen cycle in 2.5 billion years. But despite this incredible effort, all is vanity. Very little of our handiwork will survive the obliteration of the ages

At the end of all their travels—after cataloging all the bedrock of the entire planet—they might finally be led to an odd, razor-thin stratum hiding halfway up some eroding, far-flung desert canyon

Unless we fast learn how to endure on this planet, and on a scale far beyond anything we’ve yet proved ourselves capable of, the detritus of civilization will be quickly devoured by the maw of deep time.

The coronavirus pandemic is shutting down industrial activity and temporarily slashing air pollution levels around the world, satellite imagery from the European Space Agency shows.

Readings from ESA’s Sentinel-5P satellite show that over the past six weeks, levels of nitrogen dioxide (NO2) over cities and industrial clusters in Asia and Europe were markedly lower than in the same period last year.

While not a greenhouse gas itself, the pollutant originates from the same activities and industrial sectors that are responsible for a large share of the world’s carbon emissions and that drive global heating.

Dr. Clapham and his co-author, Jonathan L. Payne, a Stanford geochemist, concluded that animals with skeletons or shells made of calcium carbonate, or limestone, were more likely to die than those with skeletons of other substances. And animals that had few ways of protecting their internal chemistry were more apt to disappear. Being widely dispersed across the planet was little protection against extinction, and neither was being numerous. The deaths happened throughout the ocean. Nor was there any correlation between extinction and how a creature moved or what it ate. Instead, the authors concluded, the animals died from a lack of dissolved oxygen in the water, an excess of carbon dioxide, a reduced ability to make shells from calcium carbonate, altered ocean acidity and higher water temperatures. They also concluded that all these stresses happened rapidly and that each one amplified the effects of the others. That led to a wholesale change in the ocean’s dominant animals within just 200,000 years, or perhaps much less, Dr. Clapham said.

So what happened 252 million years ago to cause those physiological stresses in marine animals? Additional clues from carbon, calcium and nitrogen isotopes of the period, as well as from organic geochemistry, suggest a “perturbation of the global carbon cycle,” the scientists’ second paper concluded — a huge infusion of carbon into the atmosphere and the ocean.

scientists suspect that the answer lies in the biggest volcanic event of the past 500 million years — the eruptions that formed the Siberian Traps, the stairlike hilly region in northern Russia. The eruptions sent catastrophic amounts of carbon gas into the atmosphere and, ultimately, the oceans; that led to long-term ocean acidification, ocean warming and vast areas of oxygen-poor ocean water

But there is something peculiarly German about the chasm between professed moral rectitude and reckless wrongdoing, between high culture and low conduct, between angels’ wings and nitrogen oxides; and there is something peculiarly German about the devastating impact this has.

It’s time for some serious German soul-searching. Leadership demands that.

Energy “will give us serious and sustained problems” over the next 50 years as we make the transition from hydrocarbons — oil, coal, gas — to solar, wind, nuclear and other sources, but we’ll muddle through to a solution to Peak Oil and related challenges. Peak Everything Else will prove more intractable for humanity. Metals, for instance, “are entropy at work . . . from wonderful metal ores to scattered waste,” and scarcity and higher prices “will slowly increase forever,” but if we scrimp and recycle, we can make do for another century before tight constraint kicks in.

Agriculture is more worrisome. Local water shortages will cause “persistent irritation” — wars, famines. Of the three essential macro nutrient fertilizers, nitrogen is relatively plentiful and recoverable, but we’re running out of potassium and phosphorus, finite mined resources that are “necessary for all life.” Canada has large reserves of potash (the source of potassium), which is good news for Americans, but 50 to 75 percent of the known reserves of phosphate (the source of phosphorus) are located in Morocco and the western Sahara. Assuming a 2 percent annual increase in phosphorus consumption, Grantham believes the rest of the world’s reserves won’t last more than 50 years, so he expects “gamesmanship” from the phosphate-rich.

he rates soil erosion as the biggest threat of all. The world’s population could reach 10 billion within half a century — perhaps twice as many human beings as the planet’s overtaxed resources can sustainably support, perhaps six times too many.

At the rate things are going, the Earth in the coming decades could cease to be a “safe operating space” for human beings.

The paper contends that we have already crossed four “planetary boundaries.” They are the extinction rate; deforestation; the level of carbon dioxide in the atmosphere; and the flow of nitrogen and phosphorous (used on land as fertilizer) into the ocean.

“What the science has shown is that human activities — economic growth, technology, consumption — are destabilizing the global environment,” said Will Steffen, who holds appointments at the Australian National University and the Stockholm Resilience Center and is the lead author of the paper.

Something unique makes humans the top species of the planet. It’s not our exceptional brain size, but our ability to imagine the future. This skill trains us to think unlike other animals and ultimately triumph over them. And, yet, a limitation of this unique ability might also spell our doom.

At a meeting in Paris, world leaders are scratching their heads about how we can deal with the imminent threat posed by global warming. Our energy-thirsty civilization is guzzling fossil fuels at an unsustainable rate and we are soon to run out our carbon budget. If we don’t act now, disastrous consequences are predicted: rising sea levels, extreme weather events, easy-to-spread infections and so on.

But, as Arnold Schwarzenegger makes it clear, despite our ability to dream up dystopia, “Stuff that happens in the future does not mean anything to people.” It’s a limitation that could seriously hinder a successful outcome in Paris.

A long-established San Francisco fertility clinic experienced a liquid nitrogen failure in a storage tank holding thousands of frozen eggs and embryos for future use, jeopardizing tissue hundreds of women had stored in hopes of having children.

“We can’t say definitively nothing like this has ever happened, but we are certainly not aware of anything,” said Sean Tipton, the association’s chief policy, advocacy and development officer. “Now that we have a second incident, it becomes very important that we learn as much as we can about both, to search for commonalities and see if there are . . . risks that have now come to light that need to be addressed.”

On Saturday night, the half-dozen doctors who work at Pacific Fertility were finally able to begin making phone calls to some 400 patients who had all their eggs or embryos stored in storage tank No. 4.

The Earth was formed around 4.54 billion years ago. If you condense that huge swath of prehistory into a single calendar year, then the 3.95-billion-year-old graphite that the Tokyo team analyzed was created in the third week of February. By contrast, the earliest fossils ever found are 3.7 billion years old; they were created in the second week of March.

Those fossils, from the Isua Belt in southwest Greenland, are stromatolites—layered structures created by communities of bacteria. And as I reported last year, their presence suggests that life already existed in a sophisticated form at the 3.7-billion-year mark, and so must have arisen much earlier. And indeed, scientists have found traces of biologically produced graphite throughout the region, in other Isua Belt rocks that are 3.8 billion years old, and in hydrothermal vents off the coast of Quebec that are at least a similar age, and possibly even older.

“As far back as the rock record extends—that is, as far back as we can look for direct evidence of early life, we are finding it. Earth has been a biotic, life-sustaining planet since close to its beginning.”

I was dismissive of the Anthropocene, a proposed new epoch of Earth history that has long since escaped its geoscience origins to become a dimly defined buzzword and, as such (I argued), serves to inflate humanity’s eventual geological legacy to those unfamiliar with deep time.

Wing is on the Anthropocene Working Group, a group of scientists working to define just such an epoch. He hated my essay. In his manner, though, he was extremely nice about it.

the essence of a lot of Faulkner is, before you can be something new and different, slavery is always there, the legacy of slavery is not erased, ‘The past is never dead. It’s not even past,’

Thiel’s unique role in the American political ecosystem. He is the techiest of tech evangelists, the purest distillation of Silicon Valley’s reigning ethos. As such, he has become the embodiment of a strain of thinking that is pronounced—and growing—among tech founders.

why does he want to cut off politicians

But the days when great men could achieve great things in government are gone, Thiel believes. He disdains what the federal apparatus has become: rule-bound, stifling of innovation, a “senile, central-left regime.”

After around two decades of government support, China now boasts the world's largest market for e-buses, making up more than 95% of global stock. At the end of 2022, China's Ministry of Transport announced that more than three-quarters (77% or 542,600) of all urban buses in the country were "new energy vehicles", a term used by the Chinese government to include pure electric, plug-in hybrids, and fuel cell vehicles powered by alternative fuels such as hydrogen and methanol. In 2022, around 84% of the new energy bus fleet was pure electric.

. In 2015, 78% of Chinese urban buses still used diesel or gas, according to the World Resources Institute (WRI). The NGO now estimates that if China follows through on its stated decarbonisation policies, its road transport emissions will peak before 2030.

China is also home to some of the world's biggest electric bus manufacturers, such as Yutong, which has been raking up orders across China, Europe and Latin America.

While a number of factors aided what many have called a miracle at Haneda Airport — a well trained crew of 12; a veteran pilot with 12,000 hours of flight experience; advanced aircraft design and materials — the relative absence of panic onboard during the emergency procedure perhaps helped the most.

“Even though I heard screams, mostly people were calm and didn’t stand up from their seats but kept sitting and waiting,” said Aruto Iwama, a passenger who gave a video interview to the newspaper The Guardian. “That’s why I think we were able to escape smoothly.”

Experts said that while crews are trained — and passenger jets are tested — for cabin evacuations within 90 seconds in an emergency landing, technical specifications on the 2-year-old Airbus A350-900 most likely gave those on the flight a bit more time to escape.
