1 . The streets, sidewalks and roofs of cities all absorb heat during the day, making some urban areas across the United States up to 6 degrees Fahrenheit hotter than rural ones during the day—and 22 degrees F hotter at night. These “urban heat islands” can also develop underground as the city heat spreads downward, beneath the surface. And basements, subway tunnels and other underground infrastructure also constantly bleed heat into the surrounding earth, creating hotspots. Now the underground heat is building up as the planet warms.
According to a new study of downtown Chicago, underground hotspots may threaten the very same structures that emit the heat in the first place. Such temperature changes make the ground around them expand and contract (收缩) enough to cause potential damage. “Without anyone realizing it, the city of Chicago’s downtown was deforming,” says the study’s author Alessandro F. Rotta Loria, a civil and environmental engineer at Northwestern University.
The findings, published in Communications Engineering, expose a “silent hazard (危险)” to civil infrastructure in cities with soft er ground — especially those near water — Rotta Loria says. “There might have been structural issues caused by this underground climate change that happened, and we didn’t even realize,” he adds. While not an immediate or direct danger to human lives, this previously unknown effect highlights the impacts of a lesser-known component of climate change.
Similar to climate change above the surface, these underground changes occur over long periods of time. “These effects took decades, a century, to develop,” Rotta Loria says, adding that elevated underground temperatures would likewise take a long time to dissipate (逐渐消失) on their own.
But other researchers interviewed for this story all say this wasted energy could also be recycled, presenting an opportunity to both cool the subsurface and save on energy costs. Subway tunnels and basements could be updated with technologies to recapture the heat. For example, water pipes could be installed to run through underground hotspots and pick up some of the heat energy.

2 . A new project in the Caribbean is setting out to save coral reefs(珊瑚礁)- and the world. The Ocean-Shot Project, spearheaded by climate scientist Dr. Deborah Brosnan, launched in 2021 to develop a “massive, first-of-its-kind” coral reef restoration initiative in the Caribbean country Antigua and Barbuda.
“We lose more coral reefs in a day that we can restore in a decade,”Brosnan said. “Our progress towards protecting coral reefs——which ultimately protect us——is too slow. So Ocean- Shot Project is about literally rebuilding the reefs, the architecture of the reefs, for the future. ”
What sets this project apart from other coral reef restoration projects is its focus——the architecture of the reef itself. While many initiatives prioritize saving the corals, Ocean-Shot Project tacks on the additional focus of developing the base for those corals to grow and thrive.
“Coral secretes(分泌) calcium carbonate, creating a sort-of concrete around itself that becomes the structure for the reef. But that process can take hundreds and thousands of years,”Brosnan said. And with coral bleaching(白化) events only predicted to become more intense in the coming decades as global and ocean temperatures warm, this can be a problem for reefs that need to be able to recover.
“What we’re doing is we’re saying, ‘let’s learn from the corals, let’s learn from nature,’”Brosnan said. “And let’s make this happen quickly.”
To make that happen, her team is creating reef structures in a lab and then planting them in the ocean, a process that Brosnan likened to“gardening”. The team is also planting“resilient corals”among the structures that have already survived several bleaching events. Previously, her team deployed their first set of these structures, called modules, into the ocean around Antigua and Barbuda. And it’s already seeing significant success.
“We saw a whole ecosystem start to recognize these reefs as home and just move right on in. So what it told us is that if we provide the living structure, the ecosystem will respond in return,”Brosnan said.

4 . Bird populations in the UK continue to crash, new data shows, as campaigners predict the government will fail to meet its own nature targets unless radical (彻底的) changes are made. In 2021, on average the abundance of 130 breeding species was 12% below its 1970 value. Between 2015 and 2020, 24% of species increased, 28% showed little change and 48% declined. Wildlife experts agree that the decline in bird populations is largely driven by habitat loss.
The government passed the Environment Act into law in 2021, which requires a halt in species decline by 2030. Campaigners have said that radical changes to government policy are needed if it is to meet its targets. The problems were highlighted by the RSPB’s Big Garden Birdwatch this year, in which house sparrows remained the most frequently observed species in gardens for the 20th year in a row.
“The numbers speak for themselves when it comes to the astonishing declines of some of our once common birds,” said Beccy Speight, the RSPB’s chief executive. “We are in a nature and climate emergency and we’ve lost 38 million birds from our skies in the past 50 years. “This year, more than 500,000 people took part in the Big Garden Birdwatch, and more than 9 million birds were spotted. The results also identified problems faced by other common bird species, including chaffinches and greenfinches.
Richard Benwell, the chief executive of the environmental coalition Wildlife and Countryside Link, said: “Meeting the legal target to stop wildlife losses by the end of the next parliament (议会) can’t be achieved with a legal tweak (调整) here, some spare change there. Serious, sustained investment, proper punishment for pollution, and action in every department of government must be the features of any nature-positive manifesto (宣言).”

5 . Climate experts have warned about the many ways a warming planet can negatively affect human health.

Vibrio vulnificus (创伤弧菌) flourishes in salty or brackish waters above 68℉. Infections are currently rare in the U.S., but that’s likely to change. Using 30 years of data on infections, scientists at the University of East Anglia in the U.K. found that Vibrio vulnificusis
“We’re seeing the core
Based on the latest data on how much the world’s water and air temperatures will rise, the scientists predict that by 2081, Vibrio vulnificus infections could reach every state along the U.S. East Coast. Currently, only about 80 cases are reported in the U.S. each year; by 2081, that could go up to over three-fold, the authors say.
Such a proliferation could have serious health consequences. Vibrio vulnificus kills approximately 20% of the healthy people it infects, and 50% of those with weakened immune systems. There is little evidence that antibiotics can
Warming sea temperatures aren’t the only reasons behind the rise of Vibrio vulnificus. Hotter air also draws more people to the coasts and bays, bringing them into closer contact with the bacteria.

In a coastal village named Seaford, lived a courageous young woman named Amelia. Amelia was known throughout Seaford for her adventurous nature. From the moment she could walk, she would eagerly run towards the crashing waves, feeling the sand between her toes and the cool spray of the ocean mist on her face. She was a woman with a strong will and possessed a heart full of kindness. Amelia’s love for the ocean was intense, and she spent most of her days exploring the beautiful beaches and sparkling waters that surrounded her house.
One sunny morning, while Amelia was walking along the shore, she noticed a group of restless seagulls abnormally circling above the crashing waves. Their unusual calls echoed (回) through the air. Concerned for their well-being, she followed their flight pattern, her instincts guiding her toward danger.
As she approached a towering cliff, Amelia gasped in horror. On a narrow ledge (岩架), high above the violent waves, was a young dolphin trapped in a thick fishing net. Its shiny body shone under the golden rays of the sun, but its freedom was cruelly limited by the trap. With each struggle, the net tightened around its delicate body, leaving painful marks on its skin. Its tail flapped helplessly, each movement a request for help, while its desperate cries for assistance echoed through the air.
A sense of urgency filled her, pushing her forward with determination and resolve. Realizing that time was tight, Amelia knew she had to act instantly to free this innocent creature from its difficult position before it submitted to exhaustion or the force of the tides.

A child was standing on a street-corner. He leaned with one shoulder against a high board-fence and swayed the other to and fro, while kicking carelessly at the gravel.
Sunshine beat upon the cobbles (鹅卵石), and a lazy summer wind raised yellow dust which trailed in clouds down the avenue. Clattering trucks moved with indistinctness through it. The child stood dreamily gazing.
After a time, a little dark-brown dog came trotting with an intent air down the sidewalk. A short rope was dragging from his neck. Occasionally he trod upon the end of it and stumbled.
He stopped opposite the child, and the two regarded each other. The dog hesitated for a moment, but presently he made some little advances with his tail. The child put out his hand and called him. In an apologetic manner, the dog came close, and the two had an interchange of friendly pattings and waggles. The dog became more enthusiastic with each moment of the interview, until with his gleeful caperings he threatened to overturn the child. Whereupon the child lifted his hand and struck the dog with a blow upon the head.
This thing seemed to overpower and astonish the little dark-brown dog, and wounded him to the heart. He sank down in despair at the child’s feet. When the blow was repeated, together with an admonition (警告) in childish sentences, he turned over upon his back, and held his paws in a peculiar (奇怪的) manner. At the same time, with his ears and his eyes, he offered a small prayer to the child.
He looked so comical on his back, and holding his paws peculiarly, that the child was greatly amused and gave him little taps repeatedly, to keep him so. But the little dark-brown dog took this chastisement (惩罚) in the most serious way, and no doubt considered that he had committed some grave crime, for he wriggled contritely and showed his repentance in every way that was in his power. He pleaded with the child and petitioned him, and offered more prayers.
At last the child grew weary of this amusement and turned toward home. The dog was praying at the time. He lay on his back and turned his eyes upon the retreating form.
