I was an extremely shy girl in primary school and couldn’t make friends easily. My teacher, Mr. Doocy, called my mother and explained that I hadn’t spoken a single word in class. And we were more than half way through the school year. Even as a little girl, I knew this was unusual. I watched the free and happy interaction of my classmates with envy.
Mom tried to excuse my behavior as something that I would outgrow. But Mr. Doocy was still quite concerned about me. He asked Mom if I had something at home that I liked. He said he would arrange a show-and-tell activity for the class if I brought it to school. My mom told him about my cat who had given birth to several baby cats about three weeks earlier. I was crazy about those baby cats.
Then Mr. Doocy suggested I bring the baby cats to school the next day and introduce them to my classmates. It seemed that Mom didn’t think this show-and-tell activity would help me and hoped to discourage Mr. Doocy. She explained that I would have to bring the mother cat along with the six baby cats because they were too young to be separated from their mother. She probably thought this would put an end to the plan. But Mr. Doocy said that was fine.
I normally walked to school, but my mother drove me the next morning along with a big brown cardboard box. I struggled to walk toward the classroom with the heavy load. In no time, the group of baby cats caught the attention of my classmates. Their eyes lit up in wonder when they caught sight of my tiny treasures. My heart beat quickly against my chest as pride swelled within me. I had never felt so important in my entire nine years of life!
Mr. Doocy instructed me to sit on the steps outside the classroom so everyone could get a good look inside the container. “Can I hold one?” a little girl asked aloud with excitement. Then all the other children chimed in like a choir, begging to hold one of the baby cats.

2 . Antarctica (南极洲) is a great, icy land, surrounded by the huge Southern Ocean. The ice in Antarctica doesn’t just cover the land. There’s also a large area of sea ice, which floats (漂浮) on the ocean’s surface.
Scientists have been measuring the area of the sea ice in Antarctica since 1979. For most of this time, Antarctica has seemed to be almost not influenced by the changing weather conditions experienced in other parts of the planet. In fact, until recent years, Antartica’s sea ice area mainly set records for growing.
That began to change around 2016. Now, for several years, the area of Antartica’s sea ice has been getting smaller. This year, the US National Snow and Ice Data Center (NSIDC) reported that Antartica’s sea ice reached its maximum on September 10 — almost two weeks earlier than normal. And the sea ice was at a new record low — not just by a little bit, but by a lot.
The last time Antartica’s low sea ice set a record at the end of winter was in 1986. And this year, there’s about 1.03 million square kilometers less sea ice than in 1986. It’s hard to picture such a large area, but it’s around 1.6 times the size of France.
Scientists are still trying to understand what is driving the change in Antarctica. Ted Scambos, a research scientist at the University of Colorado, says, “Antarctica’s ice levels have always changed some, but the situation this year is pointing towards warmer ocean conditions around the area.”
The new low record has scientists worried. The sea ice is important, because it helps cool the planet. When it’s frozen, sea ice reflects sunlight back out into space. But when the sea ice melts (融化), the water left behind is darker, and takes in and keeps more heat.

4 . Ocean temperature extremes are now normal, a new study reports. It has analyzed ocean surface temperatures for the past 150 years. It reveals that by 2019, 57 percent of the ocean’s surface was warming to temperatures rarely seen 100 years ago.
Ecologists wanted to learn how often modern extreme heat events occur. They also wanted to see how long they last. Kisei Tanaka was one of those ecologists. He now works for the National Oceanic and Atmospheric Administration (NOAA) in Honolulu, Hawaii. Tanaka teamed up with Kyle Van Houtan, who works at the Loggerhead Marinelife Center. The two analyzed monthly sea surface temperatures collected from 1870 through 2019. Then they mapped where and when extreme heat events had shown up, decade by decade.
By looking at monthly extremes instead of annual averages, the two found that over time, more and more patches (区域) of water were reaching extreme temperatures. Then, in 2014, the entire ocean hit a point of no return, Van Houtan says.
Heat waves harm ocean ecosystems. They can lead seabirds to starve... And animals—from fish and whales to turtles—may have to swim long distances in search of comfortable temperatures.
In May 2020, NOAA announced that it was updating what climates it now considered “normal”. These values are what the agency uses to put daily weather events in a historical context. The average values from 1991 to 2020 are now higher than those from 1981 to 2010, NOAA found.
Van Houtan says his new study shows extreme ocean warming is now the norm. Much discussion on climate change, he notes, has been about future events, and whether or not they might happen. But what the emerging data make clear, he says, is that extreme heat became common in our ocean in 2014. It’s a documented historical fact—not a future possibility.

5 . Lake Mary Jane in central Florida, where people living along the lake like to go boating and swimming and watch the wildlife, is under pressure from development. Orange County, which surrounds the lake, is one of the fastest-growing counties in Florida. A development planned for a site just north of Mary Jane would transform nineteen hundred acres of wetlands and cypress forest into homes.
In an effort to protect herself, Mary Jane is suing (起诉). The lake has filed a case (立案) in Florida state court, stressing that the development would negatively impact the lake, causing concrete, distinct, and visible injuries. Mary Jane’s case is the first in American history. Never before has a lifeless slice of nature tried to defend its rights in the court. “It is long past time to recognize that we are dependent on nature and the continued destruction of nature needs to stop,” Mari Margil, director of the Center for Democratic and Environmental Rights, said in a statement.
The concept that natural objects like woods and streams should have rights was first put forward half a century ago, by Christopher Stone, a law professor who was assigned to teach University of Southern California’s introductory course on property law in 1971. He explained how ownership rights had developed over time and why our natural objects like trees or even rocks should also be given rights. This little thought experiment set off a heated debate nationwide.
Each time there is a movement to give rights to some new things, the proposal is bound to sound odd or frightening or laughable. However, this extension of rights, Stone argued, was needed to address an unavoidable problem. So long as natural objects were valued only in terms of their worth to humans — for the use of humans they could, quite legally, be destroyed.
Despite the fact that the developer is pushing to have Mary Jane’s case dismissed, arguing that the rights the lake wants do not — and cannot — exist, people are starting taking Stone’s words seriously. Even Stone’s critics had fun with his idea. There’s no way to get back to the past. The lake’s wish is pretty clear: It just wants to be left alone.
1. What challenge is Lake Mary Jane facing?| A．The negative effect of the locals’ leisure activities. | B．The loss of the wetlands due to the climate change. |
| C．The ever-increasing wildlife population in the area. | D．The housing development affecting its environment. |
| A．Intolerant. | B．Unclear. | C．Approving. | D．Doubtful. |
| A．To inspire his students’ curiosity. | B．To evaluate the value of natural things. |
| C．To avoid being laughed at by his critics. | D．To keep people from destroying nature. |
| A．Stone will face more criticisms. |
| B．The influence of the case is great. |
| C．Lake Mary Jane is bound to win the case. |
| D．The claim of Lake Mary Jane is ridiculous. |
6 . The color of the ocean has changed greatly over the last 20 years and human-caused climate change is probably responsible, according to a new study.
More than 56% of the world’s oceans have changed color, and this cannot be explained by natural changes, said a team of researchers. Tropical (热带的) oceans close to the equator especially have become greener in the past two decades, reflecting changes in their ecosystems.
The color of the ocean is derived from the materials found in its upper layers. For example, a deep blue sea will have very little life in it, while a green color means there are ecosystems there. The ecosystems are based on plant-like small living things which include chlorophyll(叶绿素). The living things form the base of a food web which supports larger creatures such as fish, seabirds and some other sea animals.
It’s not clear exactly how these ecosystems are changing, said study author Stephanie Dutkiewicz. Ocean ecosystems are finely balanced and any change in the small living things will influence the food chain. “All changes are causing an imbalance in the natural organization of ecosystems. Such imbalance will only get worse over time if our oceans keep heating,”she said. It will also affect the ocean’s ability to act as a store of carbon(碳), Dutkiewicz said, as different living things take in different amounts of carbon.
The researchers are still working to find out exactly what the changes mean. However, what is clear, they said, is that the changes are being driven by human-caused climate change.
The researchers checked changes in ocean color from space by following how much greenor blue light was reflected from the surface of the sea. They studied the changes in color from 2002 to 2022. And then they used climate change models to see what would happen to the oceans both with additional(额外的) planet-heating pollution and without.
The color changes matched almost exactly what Dutkiewicz said would happen if greenhouse gases were added to the atmosphere — around 50% of our oceans would change color.

7 . Marine life (海洋生物) in Florida Keys is negatively influenced by two forces: human activity and climate change. The former involves fishing, tourism and diving while the latter causes a large increase in intense hurricanes. Fortunately, when the researchers of Florida Museum of Natural History started looking for sea urchins (海胆) on the ocean floor off the coast of Florida Keys in the summer of 2020, they uncovered their population had relatively been stable since the 1960s.
The researchers visited 27 sites along a 20-mile stretch of coast near Florida Keys looking for tracks that reflected the presence of burrowing echinoids (穴居海胆类动物). “The findings that burrowing echinoids have been highly resilient (有适应力的) against climate change and environmental pollution over the last 60 years was a huge discovery for us.” said study co-author Tobias Grun.
Grun said, “However, we know little about their current distribution, population size, and health. The reason is not the lack of interest by the scientific community but lies in that fieldwork is very expensive.”
As the climate crisis progresses, it’s important to understand why some marine creatures are more resilient in bearing the impacts of a worsening environment than others. Grun said, “Evolution may be at play. Some marine animals are very opportunistic. They can tolerate a wide range of abiotic factors like pH, temperature, and salinity, to name a few.”
Grun added, “At this point, our data show that burrowing echinoids are more resilient than many other marine species and are doing comparatively well. That does not mean that we can push our luck and keep going the way we are right now. Our study provides some hope that these creatures are resilient, but much more work is needed to translate our findings into a larger scale. The reasons for their resilience are also widely unknown.”

10 . Whether you call them feral pigs, boar, swine, hogs, or even razorbacks, wild pigs are one of the most damaging invasive species on Earth, and they’re infamous for damaging agriculture and native wildlife.
A big reason they’re so harmful is that they uproot soil at vast scales, like tractors ploughing a field. Our new research, published recently, is the first to calculate the global extent of this and its effects on carbon emissions.
Our findings were horrible. We discovered the total area of soil uprooted by wild pigs is likely the same area as Switzerland. This releases 4.9 million tonnes of carbon dioxide each year the same as one million cars. The majority of these emissions occur in Oceania. A huge portion of Earth’s carbon is stored in soil, so releasing even a small part of this into the atmosphere can have a huge impact on climate change.
It’s estimated that wild pigs destroy more than US$74 million worth of crops and grass each year in Australia, and more than US $270 million in just 12 states in the USA. Wild pigs have also been found to directly threaten 672 vertebrates (脊椎动物) and plant species across 54 different countries. This includes Australian ground frogs, tree frogs and multiple orchid species which are imperiled, as pigs destroy their habitats and hunt them for food.
Their geographic range is expected to expand in the coming decades, suggesting their threats to food security and biodiversity will likely worsen. But here, let’s focus on their contribution to global emissions.
One such study was conducted for three years in hardwood forests of Switzerland. The researchers found wild pigs caused soil carbon emissions to increase by around 23% per year. Similarly, a study in the Jigong Mountains National Nature Reserve in China found soil emissions increased by more than 70% per year in places disturbed by wild pigs.
