The fast shift toward clean energy technologies means global greenhouse gas emissions may fall in 2024. Recent analysis from the International Energy Agency (IEA), based on the public     1     of governments, suggests emissions may in fact have peaked last year. The finding is supported by analysis from Climate Analytics, which found a 70% chance of emissions falling from 2024 if the current growing     2     in clean technologies continues.

A growing number of major economies have already passed their period of    3     emissions, including the United States, the European Union, the United Kingdom and Japan. Compared with them, China now is the most     4    in emitting greenhouse gases, contributing 31% of the global total last year. But explosive growth in clean energy    5    means China’s emissions are set not only to fall in 2024, but to go into structural    6    . What’s more, China is currently    7     a boom in clean energy production and a historic growth of renewable energy — especially solar. Similarly,     8     is expected for batteries and electric vehicles.

A peak in global emissions is cause for optimism — but it is far from     9     the problem. More greenhouse gases will still be    10     in the atmosphere and drive severe warming, until we bring the emissions as close to zero as possible.

In an age of rapidly growing urbanization, rooftop farming has emerged as a sustainable response     1     the challenge of creating green space in cities. This innovative practice transforms rooftops into mini farms, where vegetables, fruits, and even flowers     2     (plant), providing local residents with fresh produce and adding a touch of nature to urban environments.

Rooftop farming, also     3     (refer) to as vertical agriculture, is more than just a trend; it’s a step towards environmental conservation. Green roofs with vegetation help to absorb sunlight and release moisture, cooling the air and reducing the demand for air conditioning,     4     in turn lessens energy     5     (consume) and carbon emission. Meanwhile, rooftop farms serve as educational platforms,     6     (teach) city dwellers about sustainable agriculture practices and the importance of locally     7     (source) food.

As urban populations continue to grow, rooftop farming fosters community engagement     8     promotes healthier lifestyles by providing access to fresh and organic produce. When we look towards     9     future where environmental consciousness and sustainable practices become increasingly vital, rooftop farming stands as a testament to our ability to cultivate more than just food—we cultivate hope for a     10     (green) and more resilient world.

“When a snow leopard follows its prey (猎物) among the mountain walls, it moves... softly, slowly,” explains Indian biologist Raghunandan, who has studied animals for years. “If it knocks a stone loose, it will     1     out a foot to stop it from falling and making noise.” One might be moving right now,     2     silent, maybe close by. But where?

Best known for its     3     coat and long distinctive tail, the snow leopard is one of the world’s most secretive animals. These big cats can only be found high in the remote,     4     regions of Central Asia. For this reason, and because they hunt     5     at night, they are very rarely seen.

Snow leopards have been officially protected since 1975, but enforcing this law has proven difficult. Many continue to be killed for their fur and body parts, which are     6     a fortune on the black market. In recent years, though, conflict with local herders (牧人) has also led to a number of snow leopard deaths. This is because the big cats kill the herders’ animals, and drag the bodies away high up in the mountains to eat. Thus, the herders’ animals are in danger of snow leopard attacks, which can push those herders into desperate poverty. To address this problem, local religious leaders have called for an end to snow leopard killings, saying that these wild animals have the     7     to exist peacefully. They’ve also tried to     8     people that it is of great importance to protect those big cats.

As a result of these pressures, the     9     snow leopard population is estimated at only 4,000 to 7,000, and some fear that the actual number may already have dropped below 3,500．The only way to     10     this trend and bring these cats back from their threatened status, say conservationists, is to make them more valuable alive than dead.

The Curious World of Bats

Not all bats are unbelievably adorable, like the one below. Many of them have     1     faces and large ears that help them “see” in the dark, using echo location (回声定位). But all bats are, without a doubt,     2     creatures.

Scientists are typically reluctant to     3     about bats because they make up such a large and diverse group of winged animals. With nearly 1, 500 species, bats     4     about one-fifth of all mammal (哺乳动物) species on Earth. But one thing that can be said about them as a group is that they are, in not- so-scientific terms, very odd. “They break all the     5    ,” said Cori Lausen, a bat expert at the environmental group Wildlife Conservation Society Canada.

Being able to fly is just one of their     6    , since mammals rarely fly. Apart from that, bats can also push their heart rate to extreme highs and lows-as slow as one beat per minute. Many bat species can go into a period of deep sleep, known as “torpor”, for a few hours a day or even for weeks to     7     energy when it’s cold or food is unavailable. And while most small mammals have short lives and lots of babies, some bats can live for two decades or more and typically have just one baby per year.

For how much energy they need, it’s also surprising that many bat species, including most of those in the US, rely on insects alone for food. They have to eat ridiculous quantities of them. A mom that is     8     a baby can catch more than 4,000 insects in one night.

Oddly, although bats can fly, they can’t easily take off from a(n)     9     position, like most birds and insects do. That’s one reason why they hang upside down-bats have to gain the momentum they need by falling. “For them, it’s not upside down,” Frick said. “It’s flight-side ready!”

While bats remain highly understudied relative to birds and other mammals, scientists are     10     the alarm. In North America, more than half of all bat species are at risk of severe population decline. Climate change, they say, threatens to only speed up their extinction.

Oyster mushrooms feature in cuisines around the world, but they should be off the menu for hungry worms -- which these delicious mushrooms will kill and eat. Now researchers finally know how they do it.

A study published in Science Advances details how oyster mushrooms use a particular poisonous substance to freeze and get rid of mushroom-eating roundworms called nematodes (线虫). The mushrooms, which grow on nutrient-poor dead wood, then     1     the worms for nutrition.

“Nematodes happen to be the most     2     animals these mushrooms encounter. So I think,     3    , this cross-kingdom interaction is very interesting,” says study senior author.

The study team of geneticists, biochemists and biologists had previously found that oyster mushrooms release an unidentified poisonous substance that will somehow     4     the worms within minutes and cause a chemical element to flow into their cells, killing them. This     5     differs from those used by other meat-eating mushrooms and could be unique to oyster mushrooms.

For their new work, the researchers grew and analyzed samples of the mushroom’s tissue, finding no noticeable poison even when they broke it up. They reasoned that whatever was killing the worms must be a kind of     6     compound that disappears into air when disturbed. When they damaged the oyster mushroom tissue again and     7     analyzed the nearby air, they finally found a nerve gas that turned out to be contained with tiny, special-shaped structures on the mushroom surface. When nematodes touch the mushrooms, these structures     8     their gas, disturbing the worms’ cell walls to cause immobility and death. The worm is then digested by the mushrooms.

Before this study, “we underestimated the     9     to which wild mushrooms defend against or consume nematodes,” notes Nick Talbot, a geneticist at Sainsbury Laboratory in Norwich, England. The study demonstrates “a very     10     approach,” he adds. “These organisms are really difficult to work on, and Dr. Hsueh is showing that you can do some really amazing work with them.”

A team of scientists led by Alejandro Arteaga, grantee of The Explorers Club Discovery Expeditions and researcher at Khamai Foundation, discovered three new cryptozoic (living underground) snakes dwelling under graveyards (墓地) and churches in remote towns in the Andes region of Ecuador.

It was an exploration that led to the most     1    of places.

First published in the journal, Zookeys, Arteaga and his team named the small brown color-patterned snakes in honor of institutions or people supporting the exploration and    2     of remote cloud forests in the tropics.

The Discovery Ground Snake (Atractus discovery) was found underground in a small graveyard. Two     3    new species were found near an old church and inside a small school. Destruction of the snake’s native forest habitat may have forced them to     4     to these people-less areas according to Arteaga’s findings.

Atractus discovery was named to honor The Explorers Club Discovery Expedition Grants     5    , a program seeking to foster scientific understanding for the betterment of humanity and all life on Earth and beyond. The grant program supports researchers and explorers from around the world in their quest to ease the climate change crisis, prevent the extinction of species and cultures, and    6    the health of the Earth and its inhabitants.

Atractus zgap was named in honor of the Zoological Society for the Conservation of Species and Populations (ZGAP), a(n)     7     seeking to conserve unknown but highly endangered species and their natural environment.

Atractus michaelsabini was named in honor of Michael Sabin, grandson of American philanthropist and conservationist Andrew Sabin. Through conservation organization Re:wild, the Sabin family has supported field research of threatened reptiles and has protected thousands of acres of     8     habitat throughout the world.

“The discovery of these new snakes is only the first step towards a much larger conservation project,” says Arteaga. “We have already started the process of establishing a nature     9     to protect the ground snakes. This action would not have been possible without first unveiling the existence of these unique and cryptic reptiles, even if it meant     10     disturbing the peace of the dead in the graveyard where they lived.”

A new way to reduce poaching

Researchers are working on a pilot program backed by Russia’s Rosatom Corp to inject rhino horns (犀牛角) with radioactive material, a strategy that could discourage consumption and make it easier to detect illegal trade.

Poachers (偷猎者) killed 394 rhinos in South Africa for their horns last year, government data shows, with public and private game     1     lacking the resources needed to monitor vast tracts of land and protect the animals that live there. While the toll was a third lower than in 2019 and the sixth     2     drop, illegal hunting remains the biggest threat to about 20,000 of the animals in the country — the world’s biggest population.

Thousands of     3     sensors along international borders could be used to detect a small quantity of radioactive material     4     into the horns, according to James Larkin, a professor at the University of Witswatersrand in Johannesburg, who has a background in radiation protection and nuclear security. “A whole new     5     of people could be able to detect the illegal movement of rhino horn,” he said. Some alternate methods of discouraging poaching, including poisoning, dyeing and removing the horns, have raised a variety of opinions as to their virtue and efficacy.

Known as The Rhisotope Project, the new anti-poaching     6     started earlier this month with the injection of an amino acid (氨基酸) into two rhinos’ horns in order to detect whether the compound will move into the animals’ bodies. Also,     7     studies using computer modeling and a replica rhino head will be done to determine a safe dose of radioactive material. Rhino horn is used in traditional medicine, as it is believed to cure disease such as cancer,     8     as a show of wealth and given as gifts.

“If we make it radioactive, these people will be hesitant to buy it,” Larkin said. “We’re pushing on the whole supply chain.”

Besides Russia’s state-owned nuclear company, the University of Witwatersrand, scientists and private rhino owners are involved in the project. If the method is     9     feasible, it could also be used to curb illegal trade in elephant ivory.

“Once we have developed the whole project and got to the point where we completed the proof of concept, then we will be making this whole idea     10     to whoever wants to use it,” Larkin said.

The nature is part of us. Therefore, it holds a mysterious     1     for me. In my memory, the valley was quiet and calm, only to see the wheat all over the mountains waving together in rhythm when the wind blew through, like a ballet troupe. The sun rose every morning as usual, sweeping across the valley and ultimately falling behind the peaks. The snow that falls in winter always melts in spring, bringing new hope to this nature where everything was pleasant and beautiful.

Led by fate, I have became an environmentalist and had the honor of being invited to address students about my green lifestyle for a long time. The students were surprised at my lifestyle and maybe they thought my lifestyle was no longer suitable for modern life. Fortunately, they were still listened to whole lecture, saluting or     2     me——to some extent the applause implied their encouragement to me. As I began to interact with them under the stage, I was     3     by kids’ lack of knowledge of nature so that they had little knowledge of protecting environment.

After the address, I put up a stand in the     4     offering green food, hoping them interested in it to get the     5     experiencing a first-hand feeling of the green lifestyle no one shows any interest in. So I decided to team up with the concert     6     to run a campaign: “anyone who can answer a(n)     7     environmental question is qualified to attend the concert. Soon the music can     8     them coming here”.

Since then , I have been considering why kids today do not have the same deep appreciation for nature that I do. One of the significant factors may be that the former rural civilization has been replaced by the urban civilization. In the past, the poor played the     9     role in the nature, so they cleared the wasteland, planted crops and reproduced civilization. With the massive invasion of industrialization and urbanization, people were forced to move away from nature. The struggle between tradition and modernity, the confrontation between humans and nature has led people to believe that they are the masters of the universe. Is this really the case? It is time to think about who     10     us to destroy nature.

One of the British royal traditions is that the king or queen can     1     ownership of any unmarked mute swan in open water in Britain. For many years, this tradition was     2     with Queen Elizabeth II. Every summer, the swans on the River Thames would be counted for Her Majesty. Now, with Britain having King Charles III on the throne, this centuries-old tradition known as the Swan Upping will continue to be     3     over five days during the third week of every July.

Several years ago, when I was living in London, I went along to     4     the tradition for myself. It was a completely enjoyable experience. School kids and elderly watchers gathered ahead of the day’s launch in Marlow (马洛，一个英国城镇) to meet the Royal Swan Marker — Queen Elizabeth II’s     5     in her absence — David Barber, and other Swan Uppers, or catchers.

The Uppers themselves are a mix of old boys and younger men-all dressed in uniforms. They paddle their way upriver in a fleet of wooden boats, shiny with gold detailing. Flags flutter behind them in the     6    .

The small fleet is     7     by an armada (舰队) of watchers. A boatload of journalists is there for the     8    . Hug e passenger boats cruise alongside, trying to get a view of each catch.

Not long after, the traditional call goes out: “All up!” it’s the first catch of the day. The Uppers carefully     9     their boats around the birds, moving closer, before catching and tying them. The young swans are taken ashore and     10    , measured and recorded with rings attached to their legs. And the adult swans are checked against the records. Then the young birds are released with their family, unharmed.
