1 . Plogging is a great way to make your little area of the world a little cleaner, brighter, and safer while boosting your own health, fitness, and mood. This up and coming environmental activity began in Sweden in 2016.
Because plogging typically involves jogging or running, there are many health benefits to this eco-friendly fitness trend. However, the benefits extend beyond just improving heart health.
Before you start, you’ll need to outfit yourself with the right gear to get the job done. If you’re already running or jogging, you should have a good pair of running shoes and running apparel (装备).
Theoretically, you can go plogging almost anywhere you have permission to be. Depending on where you live, you may encounter trash along the side of the roads, parks, school playgrounds, trails, parking lots, town squares and bike paths.
A.How to do plogging |
B.Where to go plogging |
C.It has since spread around the world |
D.Here are some of the top benefits of plogging |
E.It’s important that you have the right footwear |
F.Beyond that, you’ll need a good pair of gloves to protect your hands |
G.Plogging is not, in fact, a compound word of “plodding” and “jogging” |
2 . Soot (烟灰) pollution is speeding up climate-driven melting in Antarctica, a new study suggests, raising questions about how to protect the delicate continent from an increasing number of humans who want to visit the place.
“It really makes us question, ‘Is our presence really needed?’” says Alia Khan, one of the authors of the new study. “We have quite a large black carbon footprint in Antarctica, which is enhancing snow and ice melt.”
Black carbon is the leftover thing from burning plants or fossil fuels. Soot in Antarctica comes primarily from waste gases of cruise ships (游轮), vehicles and airplanes, although some pollution travels on the wind from other parts of the globe. The dark particles (微粒) coat white snow and absorb heat from the sun the way a black T-shirt does on a warm day. The blanket of dark bits speeds up melting, which has already been happening more quickly because of global warming.
When snow and ice are uncovered, they reflect an enormous amount of sunlight before it can turn into heat. “These are the mirrors on our planet,” says Sonia Nagorski, a scientist at the University of Alaska Southeast. “When those mirrors are covered in a film of dark bits, they don’t send back that much light and heat. That means more heat is trapped on Earth, speeding up melting and contributing to global warming.”
As a scientist who personally visits Antarctica every year, Khan says she is troubled by her own research results. On the one hand, she goes to Antarctica to collect crucial data about how quickly the snow and ice there are disappearing. “But then when we come to conclusions like this, it really does make us think twice about how frequently we need to visit the continent,” she says, “and what kinds of regulations should be placed on tourism as well.” That could mean requiring that cruise ships and vehicles be electric, for example, or limiting the number of visitors each year.

3 . July was the world’s hottest month on record. Wildfires this summer destroyed a Hawaiian city and caused evacuations (疏散) in Canada, Greece, and Thailand. Floods devastated towns in Vermont in July and killed thousands of Libyans in September.
John Vaillant’s new book Fire Weather aims to shake us out of this with a tale of terror from a climate change frontline: the city of Fort McMurray, in northern Canada’s vast forest, where an uncontrollable wildfire during an exceptionally warm spring in 2016 flooded entire communities within days.
Vaillant tells his story at disaster-movie pace, starting with the glimpse of smoke on the horizon and assurances from the authorities that all will be fine. Mounting misfortune follows as the flames lick golf courses on the city’s edge. By the end, 90,00 people had been evacuated, 2,500 structures destroyed, another 500 damaged. The energy generated by the fire created its own weather system, with hurricane force winds and lightning strikes.
What attracts me most is the book’s central irony. The story takes place in Fort McMurrary, which is the industrial centre of northern Alberta’s tar sands, one of the world’s largest fossil fuel deposits. It is a city whose existence depends on the hydrocarbons whose burning caused climate change; but whose existence almost ended in a climate-caused burning.
Fire Weather isn’t a typical disaster book. Vaillant’s references to Nassim Taleb, Lucretius, Seamus Heaney, The Lord of the Rings, Xerxes, and Moby-Dick can grant. But Vaillant’s theme is also catching my eyes. Our industrial world is releasing carbon at a rate 10 times faster than scientists can find in the geological record for the past 250mn years, he writes. “Thanks to fire and our appetite for boundless energy, we have evolved into a geologic event that will be measurable a million years from now.”

4 . Artificial intelligence (AI) is showing promise in earthquake prediction, challenging the long-held belief that it is impossible. Researchers at the University of Texas, Austin, have developed an AI algorithm(算法) that correctly predicted 70% of earthquakes a week in advance during a trial in China and provided accurate strength calculations for the predicted earthquakes.
The research team believes their method succeeded because they stuck with a relatively simple machine learning approach. The AI was provided with a set of statistical features based on the team’s knowledge of earthquake physics, and then instructed to train itself using a five-year database of earthquake recordings. Once trained, the AI provided its prediction by listening for signs of incoming earthquakes within the background rumblings(隆隆声) in the Earth.
This work is clearly a milestone in research for AI-driven earthquake prediction. “You don’t see earthquakes coming,” explains Alexandros Savvaidis, a senior research scientist who leads the Texas Seismological Network Program (TexNet). “It’s a matter of milliseconds, and the only thing you can control is how prepared you are. Even with the 70% accuracy, that’s a huge result and could help minimize economic and human losses and has the potential to remarkably improve earthquake preparation worldwide.”
While it is unknown whether the same approach will work at other locations, the researchers are confident that their AI algorithm could produce more accurate predictions if used in areas with reliable earthquake tracking networks. The next step is to test artificial intelligence in Texas, since UT’s Bureau TexNet hastions and over six years worth of continuous records, making it an ideal location 300 earthquake sta for these purposes.
Eventually, the authors hope to combine the system with physics-based models. This strategy could prove especially important where data is poor or lacking. “That may be a long way off, but many advances such as this one, taken together, are what moves science forward,” concludes Scott Tinker, the bureau’s director.

6 . Saving Us: A Climate Scientist’s Case for Hope and Healing in a Divided World—Katherine Hayhoe’s new book, proposes to fight climate change through better communication. It is a follow-up to her awesome TED talk in 2018, when she declared the most important thing any individual can do to fight climate change is to talk about it.
Of many refreshing aspects of this book, one is that Hayhoe recounts both her successes and her failures to communicate, through which she has gathered evidence about what works and what does not. Much of the book’s advice is common sense, all backed up not just by Hayhoe’s experience but also with convincing research by psychologists and social scientists.
Hayhoe advises against trying to engage with a small minority, the “Dismissives”, who angrily reject the idea that human-caused climate change is a threat. Hayhoe pays special attention to Dismissives early on, noting that their aggressive posture online may create the impression that they’re everywhere. However, she argues, Dismissives account for only 7% of all American adults. The other 93% are more receptive by degree.
The book includes amusing examples of her encounters with the “Dismissives”, including an engineer who was unconvinced about the evidence but with whom she was able to establish mutual (相互的) respect through a shared passion for knitting (打毛线衣). It is also packed with inspiring accounts of how she has won over even the crowds who are the most suspicious. Her motto is “bond, connect and inspire”, which represents her approach of always looking for point s of common ground.
She also tells of a man who approached her after an event in London in 2019. Inspired by her TED talk, he had started to speak to everybody he could in his neighborhood of Wandsworth. He showed her details of 12,000 conversations that had taken place, claiming that they had helped to convince the council to declare a climate emergency and to switch investments from fossil fuels to renewable energy.
And so, while it may feel difficult to influence the outcome of the COP26, Hayhoe’s uplifting book makes a persuasive case that we can all do our bit to bring about success just by talking about the issue.

7 . The California sea otter (海獭), once hunted to the edge of extinction, has staged a thrilling comeback in the last century. Now, scientists have discovered that the otters’ success story has led to something just as remarkable: the restoration of their declining coastal marsh (沼泽) habitat.
Elkhorn Slough, a coastal marsh within Monterey Bay, had been experiencing severe damage. The root cause was a growing population of shore crabs, which fed heavily on the marsh plants, weakening the structural integrity of the habitat. Coastal marshes like these are not only natural defenses against storm waves but also serve as important carbon storage areas and water-cleaning systems.
The conservation-driven comeback of the sea otter has been crucial. California’s coastlines were once alive with sea otters. Sadly, they were nearly wiped out at the hands of fur traders. In the 1980s, conservation efforts aided these otters in re-occupying large areas of their former range. Now, Elkhorn Slough has the highest concentration of sea otters in California, with a population of about 100. By naturally feasting on crabs, the otters have helped a significant regrowth of plant life. Brent Hughes, a scientist working alongside Angelini, led a three-year study. Their findings were clear: in areas with sea otters, crab numbers fell markedly. This led to a resurgence in plant growth, which in turn stabilized the soil and lowered the rate of soil washing away.
As the sea otter population continues to restore, their positive impact on coastal ecosystems is likely to increase. It not only showcases the sea otter as a central species—a species that has a significant effect on its natural environment—but also highlights the essential nature of top predators (捕食者) in preserving ecological harmony. “My honest reaction was—this could become a classic in the literature,” says scientist Lekelia Jenkins. She reveals marsh restoration also helps people by reducing flooding. “Suddenly, sea otters go from just cute things we like to something that can protect our livelihoods and our properties.”

9 . If you look at the dynamic “Global Temperatures” map on NASA’s website, you can see the historic temperature change over time across the planet as the timeline goes from 1880 to the modern day. By 2019, the entire planet is in red, orange, and yellow colors, indicating temperatures much higher than the historical average in every country and human inhabitance.
If the timeline went to 2023, the map would look even worse. That’s because the summer of 2023 was the hottest ever, according to ocean monitors. July was the hottest month in recorded history. Next July could be worse. Unless we do something quickly, we face dealing with more and more dangerous and expensive natural disasters in the future.
Forest fires sent smoke from Canada across the North American continent, causing New York City to have the worst air quality in its recorded history. Heavy rainstorms fell on Vermont and the Northeastern United States in just a couple of days in the middle of July, which exceeded the amount that area would usually receive in two months and caused extreme damage to homes and businesses. Around the same time, flash flooding in Bucks County, Pennsylvania — north of Philadelphia — killed nearly a dozen people.
Erich Fischer, a researcher specializing in climate studies at the Swiss Federal Institute of Technology, is concerned that natural disasters could get much worse in the future—and in ways we cannot predict. He called for a “strike for climate justice,” which actually took place on Sept. 15, 2023. “The strategy needs to be twofold (双重的) . We need to decrease carbon emissions as much as realistically possible. That is already happening with people using electric cars and other green technologies. At the same time, we also need to find ways to predict the risk of natural disasters ahead of time,” said Erich Fischer.
