Human activities have caused severe narrowness in over half of the world’s largest lakes in the past 30 years, causing risks to health, economies, and the environment, according to a study in the journal Science. The global decline in water storage equals to 17 times the capacity of Lake Mead, the largest lake in the U.S. Overuse of water for agriculture, development, and human-caused climate change are the main factors driving the decline, particularly in natural lakes. The accumulation of dirt and sand behind dams also contributes to the fall of water levels in lakes.
The findings showed “significant declines,” stated Fangfang Yao, the lead author of the study. “Roughly one-quarter of the world’s population lives in a basin with a drying lake,” Yao said. “So the potential impact could be significant.”
At least half of the decline in natural lakes was driven by human-caused climate change and overconsumption, which should remind water managers to improve protection and water efficiency, according to Yao. “If you know a lake is falling and that loss resulted from human activities, can we attach more importance to protection and improving water efficiency?” she said.
A climate change-driven drought and an ever-growing human thirst have continued to consume the two largest lakes in the U.S. Lake Powell and Lake Mead, which the Colorado River feeds. Lake Chad, one of Africa’s largest freshwater lakes which supplies nearly 40 million people with water, has shrunk (收缩) by an estimated 90% since the 1960s.
The United Nations regards access to safe drinking water as a universal human right, yet around 2 billion people lack access to it, and half of the global population experiences severe water shortage annually.
“Uncertainties are increasing,” said Richard Connor, the editor-in-chief of a U.N. water report published earlier this year at a press conference in late March, where world leaders met to try and find better strategies for managing the planet’s rare freshwater. “If we don’t address it, there will definitely be a global disaster.”

【推荐1】The good news is that more people bought electric vehicles (EVs) in 2020. The bad news is that sport utility (多用途的)vehicles (SUVs) continued to grow in popularity, too. “The fall in oil consumption due to the first trend was completely canceled out by the second," said Laura Cozzi, an officer at the International Energy Agency (JEA),
Between 2010 and 2020, global carbon dioxide emissions (排放)from conventional cars fell by nearly 35 billion Lons, due to reasons such as fuel efficiency improvements as well as the switch to electric cars. Emissions from SUVs rose by more than 50 billion tons. "While the growth in EVs is encouraging, the boom in SUVs is heart-breaking," says Peters at the Cicero Climate Research Centre in Norway.
There are many reasons for the growing popularity of SUVs. For example, rising economic boom in many countries means more people are able to afford them. Some people see them as status symbols. Also, SUVs are heavily advertised by car-makers, whose profit is higher on these vehicles. Some countries, including France, have introduced plans under which more taxes are paid on heavier cars. But Peters thinks that people who are rich enough to afford SUVs won't be deterred by slightly higher taxes. "There are now some electric SUVs available, but 1 hope one day you will see more electric vehicles brought to the SUV market," says Peters.
Even if it happens, switching to electric SUVs isn't a good solution. Due to their size and bigger batteries, it takes more resources to build electric SUVs, and they consume around 15 percent more electricity. That means higher emissions unless the electricity comes entirely from renewable sources, and higher electricity demand makes it harder to green the electricity supply.
1. What can we infer from Paragraph 2?A.Scientists should devote themselves to improving fuel efficiency. |
B.The emission of carbon dioxide of motor vehicles has hit a new low. |
C.Electric vehicles will certainly take the place of sport utility vehicles. |
D.The popularity of SUVs destroys some efforts at environmental protection. |

A.SUVs are discounted heavily. |
B.SUVs are often advertised by car producers. |
C.SUVs are taxed at a lower rate in some countries. |
D.SUVs consume fewer resources than other vehicles. |
A.The electric SUVs should be made smaller and lighter. |
B.The electric SUVs are a good guarantee for less pollution. |
C.More electric SUVs don’t necessarily mean "environment-friendly". |
D.Future electric SUVs will be powered with completely green energy. |
【推荐2】Which is better for Earth: an electric or gas-powered vehicle? The answer to this question might seem blindingly obvious: Of course electric cars must be better for the environment, because they don’t give off greenhouse gases as people drive. However, electric vehicles (EVs) aren’t perfect, and they come with their own set of polluting problems. Their batteries require a large amount of energy to produce.
Battery production is just one part of an electric car’s life span. A study looked at the entire life cycle of an EV’s emissions (排放), from mining the metals for the batteries to producing the electricity needed to power them, and then compared this with the average emissions of a gas-powered vehicle. The team found that when EVs are charged with coal-powered electricity, they’re actually worse for the environment than gas-powered cars.
“Only when connected to the dirtiest, coal-heavy electric grids (电网) do gas-powered cars become comparable to EVs on a greenhouse gas basis,” said Colin Sheppard, an expert in energy and transportation systems. That’s why more and more countries are decreasing the power supply from coal. In China, the national grid is improving with more investments in renewable energy. For example, it has twice as much wind energy capacity as the U.S. and it builds more solar panels per year than any other countries.
Sheppard modelled a future in which all cars were electric. “We wanted to understand what it might be like if all passenger vehicles are electrified.” For example, Sheppard calculated that if all vehicles in the U.S. were electric, it would reduce greenhouse-gas emissions by 46% every year. This reduction could be increased even further if those vehicles were using a technique known as “smart charging” in which cars are recharged at chosen times (often at night) to reduce the cost of electricity.
In short, it’s far easier to argue in favor of buying an EV than a gas-powered vehicle. But what about the cost? Aren’t electric vehicles too expensive for most people?

【推荐3】Minh Anh Ho is sitting beside a microscope. Many people are busy with other tasks. One is interviewing the mayor for a TV news station. Another is running the electric company. As a researcher for a company that repurposes plastic, Minh Anh Ho is studying a sheet of cling wrap (保鲜膜). “It’s a really important job,” she says. “Plastic takes a really long time to disappear, so it would be good to come up with something else to do with it and not just throw it away.”
The learning center where Minh Anh Ho and her class are spending their day is designed to introduce kids to working life. Students run an imaginary town, with each kid doing a different job in a different business. Each year, about 83% of all sixth graders in Finland go through the program. It teaches them not just about business and working, but also, as Minh Anh Ho’s “job” makes clear, about the circular (循环) economy.
Most societies have linear (线性) economies, which operate on a “take, make, waste” model. Natural resources are taken from the Earth and made into products, which are usually thrown away if left over. In 2016, Finland became the first country to use a “road map” to a circular economy. This model focuses on the transformation of existing products. Businesses rely on recycled or repurposed materials and use less raw (未经加工的) material to make their products. That reduces the amount of waste going into landfills.
Education has always been a central part of Finland’s plan. Kindergarten director Liisa Woitsch is sitting on the floor with students and a broken wooden chair. “Do we just throw it away now,” she asks, “or can you think of anything else that can be done with it?” A little boy pounds on the chair. He says it can be used as a drum.
Anssi Almgren helped design the program. “Children have so many great ideas,” he says. “We want to enable them to think about solutions. But changing a society by educating its youth takes time.”

【推荐1】Even though people have been paralyzed (瘫痪的) playing sports like rugby and football, extreme sports take the whole ordeal (磨难) to the next level. Sports like downhill cycling are very dangerous because one would be going downhill, over rocky or dirt zone, through forests, even at potentially deadly speeds. A slip up could be your downfall.
Nobody who gets into extreme sports goes with the desire to do harm to themselves. With that, athletes train for years and years before they attempt anything extreme. To most people, extreme sports are extreme simply because they take more skill than what an average person has. An athlete with skill and training makes an extreme thing become a daily routine. That does not wipe out the danger, but it greatly reduces it.
Even when there is a lot of skill involved, things might not go the athlete’s way, not at all. Luck and circumstances have a lot to do with how things develop, whether above 8000 meters or in a wood, going downhill. In some places, crossing the street is an extreme sport, considering how wild traffic can get.
Some view parkour — the sports of running, jumping and climbing under, around and through buildings — as an extreme sport, while it is more of a life philosophy, where the athlete does not have to do anything remotely dangerous. Free soloing, which means climbing a rock or ice face without safety gear, is absolutely deadly, where one slip means almost certain death, depending on the height, of course. Skateboarding is relatively safe, but if you constantly find ridiculous places to practice on, like the fence of a bridge, then things can get very complicated. The extreme part depends on the athlete.
To summarize, yes, extreme sports are dangerous, but the danger depends on the athlete, their choice of sport, direction in which they take it, as well as the circumstances. Some things are out of our reach of control, while others we can influence through exercise and healthier risk choices.

【推荐2】New research added brain degradation such as Alzheimer’s disease (阿尔茨海默氏病)to the growing list of effects of fine particles (微粒). A study of 63 million adults older than 65 in the United States showed that from 2000 to 2016, firsttime hospital admissions for Alzheimer’s disease and related diseases rose by 13 percent with every 5microgram (per cubic meter of air) increase in annual concentrations of PM2.5. Such particles are produced mainly during the burning of fossil fuels, especially coal and oil. The risk remained high even when concentrations were below 12 micrograms per cubic meter of air, a level the U. S. Environmental Protection Agency currently considers safe.
“Our study builds on the small but clear evidence indicating that longterm PM2.5 exposure is associated with an increased risk of worsening brain health, even when PM2.5 concentrations are well below the current national standards,” said Xiao Wu, a doctoral student in Harvard.
Antonella Zanobetti, a coauthor of the study, said the new research results showed that the current U. S. regulations are inadequate to protect the aging American population, highlighting the need for stricter standards and policies that help further reduce PM2.5 concentrations and improve air quality overall.
Women and urban populations, particularly those in the northeast, were particularly at risk, the research showed. The researchers figured that the increasing effects on urban populations might be due to the “abundance of metalbearing particles in the urban atmosphere, which have very small size and can access the brain directly”. They owed the increased risk to women to longer life, which meant the probability of death from other causes before developing Alzheimer’s disease was higher in men.

【推荐3】Female role models are having a moment. In the United States, there is a female vice president. The women’s soccer team is fighting a public, uphill battle for equal pay. Women are even making their way into what had seemed a permanent men’s club: the senior operation ranks of the armed forces.
Role models inspire people by showing what is actually possible. Research supports that it works: these pioneers not only help us imagine where we might go but also map out the path there. Role models have also been shown to have a bigger impact on women and underrepresented communities—those who have not easily achieved their goals. Seeing more women in the world of science, girls of today are more likely, when asked to draw a scientist, to draw a woman than those in past decades. Even one role model can benefit a child, helping them perform better in school and maintain a positive attitude.
However, the idea of “good role models” needs an update, especially when it comes to girls; otherwise the endless stream of shining snapshots of achievement they see can actually lead to self-doubt. In addition to role models, our work on girls and the process of building confidence has found that what girls really need are “work in progress” models. Girls tend to judge themselves harshly and suffer from perfectionism. They need to see the struggles and failures in their role models, as well as great perseverance. Anything that suggests success effortlessly achieved can be discouraged rather than inspired, playing into girls’ worst self-doubt thinking patterns.
Helping girls see the extraordinary in the seemingly ordinary is a good solution to unrealistic expectations. “Everyday heroes have a special impact,” said the child psychologist Bonnie Zucker. “Take a young girl who has to shoulder-the-responsibility for raising her brothers or sisters for some reason. She might not have attractive social media presence, but her bravery, devotion, and emotional labor are, in fact, heroic.”

【推荐2】Back in 2011,archaeologists first discovered a lost highway littered with Viking artifacts(古器物)—sleds, horse bones, walking sticks, a 1,700—year—old sweater and heap after heap of horse dung.
But now archaeologists have discovered so much more. They've published new research describing hundreds of items that have been found along Lendbreen pass: shoes, parts of sleds, and bones from packhorses. It would have remained hidden forever had the ice not rapidly begun melting, revealing all that roadside Viking litter.
The highway winds its way over the Lendbreen ice patch(流冰区) in Norway's Jotunheim Mountains, about 200 miles north of Oslo. "The pass was at its busiest during the Viking Age around 1,000 A.D., a time of high mobility and growing trade across Scandinavia and Europe," study co—author James Barrett said.
According to researchers, the highway was possibly built around the year 300. At the time, heavy snow covered rocks underfoot. Trading posts were built along the nearby Otta River. The road may have thrived for many more centuries.
“The decline of the Lendbreen pass was probably caused by a combination of economic changes, climate change and late medieval pandemics(中世纪流行病), including the Black Death,” study co—author Lars Pilo explained. “When the local area recovered, things had changed, and the Lendbreen pass was lost to memory.”
“The objects are amazingly well preserved,” study co—author Espen Finstad added. “It is like they were lost a short time ago, not centuries or millennia ago.”
For archaeologists, the Lendbreen ice patch seems like a gift from the ancient past. But it's alarming that it's unwrapping itself so rapidly. "Global warming is leading to the melting of mountain ice worldwide," said Pilo. “Trying to save the remains of a melting world is a very exciting job—the finds are just an archaeologist's dream—but at the same time, it is also a job you cannot do without deep worry.”

【推荐3】For many animals in the ocean, crabs are food. That’s a problem for crabs. How can they stay off the dinner menu? One type of crab, known as the decorator crab, has found a clever solution. It “decorates” itself. Decorator crabs use seaweed to change their appearances so that predators (捕食者) will not recognize them.
More than 100 species of decorator crabs are found all over the world. One species, commonly called the longnose spider crab, takes decorating to a whole new level. The ocean floor was covered in seaweed, but these crabs wouldn’t use just any kind they found. “They were very, very picky, and things they pick were quite uncommon.” says Dr. Stachowicz of the University California.
He noticed that longnose spider crabs would grab a piece of seaweed and take a little bite. Sometimes they would just eat the seaweed. Other times, they would reach back and attach the piece to the small hairs on their back. These crabs were choosing to decorate themselves with seaweed that has a peppery-tasting (胡椒味) chemical in it. Most fish find this chemical unappetizing. “If the crabs just decorated to look like the background, they would be giving their predators a little side salad with the main course.” says Dr. Stachowicz. But by carefully choosing the peppery seaweed, these decorator crabs look less tasty and predators avoid them.
Once a longnose spider crab has put together a good suit to protect itself, it is set for a while. The seaweed continues to grow even while it’s stuck to the crab’s back. When a crab sheds (去除) its old shell, it has to redecorate, often using seaweed from its old shell. Basically, the crab recycles.

【推荐1】A huge block of ice has collapsed from the Marmelada mountain in Daly, leaving at least 5 dead and 10 wounded. All the mountain rescue stations in the area have been activated and the injured have been hospitalized in several hospitals, the national Rai TV reported, citing the Alpine Rescue.
“This summer risks being the perfect storm for glaciers(冰川),” said Ginvanni Baccolo. He is an environmental scientist and glacier expert at Milan-Bicocca University. Baccolo noted a lack of winter snow and a hot start to the summer affecting glaciers. “Nobody could have expected a glacier like the Marmolada to react like this,” he told Reuters. Temperatures on the normally freezing Marmolada reached 10 degrees Celsius on Saturday, Veneto area governor Luca Zaia said.
In fact, Italy has experienced early and severe summer heat. Glaciers in Europe’s Alpine Mountains, including the Dolomite Mountains, are becoming more unstable and dangerous because of rising temperatures linked to climate change.
“High altitude glaciers such as the Marmolada are often steep(陡峭的) and relying on cold temperatures below zero degrees Celsius to keep them stable.”said Poul Christoffersen. He is a professor at the University of Cambridge who studies glaciers. Christoffersen said that climate change melts more water, which releases heat that warms up the ice if the water re -freezes. He added that a worse effect would be the lifting of the glacier forn the rock below, causing a sudden unstable collapse.
Baccolo made suggestions to the climbers heading into the mountains to escape the summer heat. “The invitation I want to make to those who go to the high mountains this summer is to use much more carefulness,” he said. “The problem is that it may no longer be enough to read the signs from the glacier that have been read so far,” he added.

【推荐2】Members of a native community in the arctic areas of Sweden say their reindeer (驯鹿) are facing possible starvation from unusual weather related to climate change. The Sami indigenous community takes care of about 8,000 reindeer throughout the year. The animals are moved between traditional feeding areas in high mountains bordering Norway in the summer and forests farther east in the winter.
Community member Niila Inga is worried about his reindeer. He said climate change has affected the area’s weather activity and created food shortages. “If we don’t find better areas for them where they can graze and find food, then the reindeer will starve to death,” Inga said. He demonstrated the problem by reaching down into the snow and pulling up a hard piece of ice close to the soil.
The area received unusual snowfall early in the fall, followed by rain that froze. Inga said this traps the plants that reindeer eat under a thick cover of ice. Some of the hungry reindeer have now moved away from their traditional migration areas in search of food.
Community members say half the reindeer moved towards the east as planned. But the rest headed back to the mountains, where they face the risk of attacks by other animals or being caught in an avalanche. Older members of the Sami community say that in the past, they only encountered bad winters about once every ten years. But now extreme and strange weather is getting more and more normal, happening several times a year.
Snowfall is normal for the area. But as temperatures increase, rain can also fall, creating a “rain-on-snow” effect. When this happens, food remains trapped underneath the ice where the reindeer cannot reach it. This causes the animals to grow weaker and struggle to make it through the winter. Weather changes have hit the Sami community hard.
Sanna Vannar is president of the Swedish Sami Youth organization. The group launched (发起) a legal action in 2018 to force the European Union (EU) to set better targets for reducing human-caused greenhouse gases.
“We’ve said we don’t want money because we can’t buy better weather with money,” Vannar said. “We’ve said we need the EU to take action and they need to do it now.”

【推荐3】Parts of East Asia could see “rivers in the sky” form due to climate change, bringing record-breaking levels of rainfall with them, a new study has revealed.
The team, from the University of Tsukuba, Japan, have already seen clear signs of global warming hitting parts of the country, so they wanted to see how bad things could get. “It’s been becoming more and more clear that global warming means more than just warmer temperatures,” they wrote.
One particularly-damaging extreme weather event is an increase in rainfall to unexpected and unprecedented (前所未有的) levels, which can result in flooding. To help predict rainfall events, researchers looked to one of the causes — the interaction of atmospheric rivers with mountain ranges.
“As the name suggests, atmospheric rivers are long, narrow bands of concentrated water vapour flowing through the atmosphere,” the team explained. “When one of these bands meets a barrier, such as a mountain range, it can produce extreme levels of rainfall or snowfall.”
Parts of East Asia have been subjected to (遭受) an increasing number of damaging, extreme weather events over the past decade.
To understand the impact, the team used high-resolution global atmospheric circulations model simulations (模拟) that virtually re-create the conditions in the atmosphere. They then looked at other regional climate models, comparing simulations based on real, meteorological data (气象数据) from 1951 to 2010 to predictions for 2090.
Authors used the climate scenario that would result in 4℃ of warming, compared to preindustrial levels — which is significantly more than 2℃ target set as part of Paris Climate Agreement.
First author, Professor Yoichi Kamae, said that their simulations predict strengthened water vapour transport, as well as increased rainfall at unprecedented levels. In simulations the greatest amounts of atmospheric river-related rainfall occurred on the southern and western slopes of mountains in East Asia, including in Japan, the Korean Peninsula, and northeastern China. They had to limit the study to East Asia due to computer time and processing limitations, but predict it would apply to other regions around the world.
