1 . Thanks to the 1999 Environment Protection and Biodiversity Conservation Act, 26 endangered species in Australia have seen their populations recover.
It seems like that we're always hearing about new animals that have become endangered, but there's some good news in Australia: 26 animal species no longer meet the criteria to be listed as threatened. Australia’s biodiversity has been in decline, with more than 1, 700 species and ecological communities known to be on the line. In 1999, the Environment Protection and Biodiversity Conservation (EPBC) Act was passed to introduce protections for endangered animals. The burrowing bettong is one of 26 Australian species that have returned from the edge of extinction.
Seemingly these are working, as a recent study published in the journal Biological Conservation reviewed the animals that were previously or currently listed as threatened between 2000 and December 2022, and discovered that 26 species had recovered to no longer meet the criteria. Species that have seen improvement include the charmingly named burrowing bettong, the golden bandicoot and the bulloo grey grasswren.
Factors behind this improvement include habitat management, control of introduced predators (捕食者) and translocation of endangered animals to predator-free islands. However, the species have not been officially delisted at this time. The EPBC Act only allows species to be delisted if doing so will not have a negative effect on their survival, and researchers believe that conservation gains could be lost should management efforts be stopped.
Dr Michelle Ward, a conservation scientist at WWF Australia, told The Guardian, “The key problem with delisting species is that then they no longer have monitoring and no longer need certain funding plans.”
However, it is promising that researchers have found signs of improvement. Hopefully this will continue among these and other species!

5 . A huge section of the Milne Ice Shelf, located on Ellesmere Island in the northern Canada, collapsed into the Arctic Ocean, according to the Canadian Ice Service. This created an “ice island” which is about 30 square miles in size. As a comparison, Manhattan Island is about 23 square miles.
“Entire cities are that size. These are big pieces of ice,” Luke Copland, a glaciologist at the University of Ottawa who was part of the research team studying the ice shelf, told Reuters. “This was the largest remaining intact (完整的) ice shelf, and it’s collapsed, basically. ”
The Canadian Ice Service said on Twitter that “above-normal air temperatures, offshore winds and open water in front of the ice shelf are all part of the recipe for the ice shelf to break up.” A huge section of the Milne Ice Shelf has collapsed into the Arctic Ocean, producing a 30-square-mile ice island.
The ice shelf has now been reduced in area by about 43%. An ice shelf is a thick slab of ice, attached to a coastline and extending out over the ocean, according to the National Snow and Ice Data Center. “Some shelves have existed for thousands of years,” the center said.
So what’s going on up there? Though the planet is warming worldwide due to climate change, the Arctic has been warming at a rate twice that of the rest of the world. This summer has been particularly warm: Arctic sea ice melted to its lowest July level on record and in June, a town in Siberia soared (急升) to 100.4 degrees Fahrenheit, believed to be a record high for the Arctic.
“When I first visited those ice caps, they seemed like such a permanent fixture of the landscape,” Mark Serreze, director of the NSIDC and geographer at the University of Colorado, Boulder, said in a statement. “To watch them die in less than 40 years just blows me away.”

7 . There are two distinctive types of electric buses making their way along Nanjing Xi Lu, one of Shanghai’s busiest roads. The first is a fleet of blue trolleybuses that serve bus route number 20, a line set up by a British-run transport company in 1928. They use poles to receive electricity from wires overhead and have kept the route running in this way for nearly a century. But while the historic electric buses are a reminder of Europe’s past technological innovation, the new buses traveling alongside them are symbols of China’s contemporary net-zero ambition. These modern electric buses powered by lithium batteries (锂电池) , were introduced in Shanghai in 2014. They offer a smoother ride, especially during starts and stops. Widely used across China, these buses are key to the country’s EV transition and are influencing the global shift towards green transportation.
The most recent data available shows that China in 2018 was still the second largest source of carbon dioxide emissions in the global transport sector, responsible for 11%, and behind only the United States, which accounted for 21%. After around two decades of government support, China now boasts the world’s largest market for e-buses, making up more than 95% of global stock. At the end of 2022, China’s Ministry of Transport announced that more than three-quarters (77% or 542, 600) of all urban buses in the country were new energy vehicles. The speed of this transition was remarkable.
So far, however, the Chinese cities with the most successful e-bus introduction — such as Shenzhen, Beijing and Shanghai — all have moderate weather and are relatively flat. To take its e-bus campaign to the next level, China faces challenges. For one thing, it is difficult to bring fleets to cities such as Hong Kong, which — like London — have double-deckers. These two-storeyed vehicles are “very hard” to electrify, because they are heavier, use more energy, and so need bigger batteries, reducing the number of passengers they can carry. Cold weather is a problem, too, as it can make a battery’s charging time longer and its range shorter. The reason China has not achieved 100% electrification for its buses is its northern regions, which have cold winters, says Xue Lulu, a transportation expert at the World Resources Institute China.

8 . It has been over 150 years since the Great Chicago Fire. The 1871 fire killed an estimated 300 people. It turned the heart of the city, wood-frame buildings quickly constructed on wooden sidewalks, into ruins, and left 100,000 people homeless. Like the Great Fire of London in 1666, the San Francisco Earthquake of 1906, and Hurricane Katrina in 2005, the Great Chicago Fire reminds us that big cities can still be frail.
But that same night, about 250 miles north of Chicago, more than 1,200 people died in and around Peshtigo. It was the deadliest wildfire in U.S. history. Survivors said the fire moved like a hurricane, jumping across Green Bay to light forests on the opposite shore.
Chicago’s fire came to be seen as a disaster that also led to the invention of steel skyscrapers, raised up on the city’s ashes. It has overshadowed the Peshtigo Fire. And for years, the two were seen as separate disasters. However, many of those houses and sidewalks that burned in Chicago had been built with trees grown around Peshtigo.
Chicago’s fire was long blamed - falsely - on an Irish-immigrant family’s cow kicking over a lantern. Some people thought the Peshtigo Fire started when pieces of a comet (彗星) landed in the forest, which has never been proven.
What we understand better today was that the Midwest was historically dry in the summer of 1871. When a low-pressure front with cooler temperatures rolled in, it produced winds, which can fan sparks (火星) into wildfires. The fires themselves generated more winds. Several parts of nearby Michigan also burned during the same few days ; at least 500 people were killed there.
At present, all of those fires on an autumn night in 1871 might help us see even more clearly how rising global temperatures and severe droughts, from Australia to Algeria to California, have made forests easier to burn, and people more likely to be harmed by the climate changes we’ ve helped create.

9 . The opening of California’s commercial crab season, which normally starts in November, is delayed once again to protect whales searching for their prey (猎物) along the coast.
California has been affected by a marine heat wave since May. The Blob, as this mass of warm water has become known, is squeezing cooler water preferred by whales and their prey close to shore, where fishermen set their traps. This crowding can lead to tangle (缠结) between whales and fishing equipment, endangering the animals’ lives and requiring rescue missions.
In a new study, scientists say they can now use global temperature models, commonly used in climate science, to predict up to a year in advance when hot ocean temperatures raise the risk of tangles between whales and fishing equipment.The tool analyzed in the new study, called the Habitat Compression Index, works by feeding sea-surface temperature measurements into an equation (方程式) that estimates the likelihood of whale habitat shrinking closer to shore.Regulators and fishermen agree that the new forecasting research could help them walk the tightrope between protecting whales and protecting local livelihoods (生计).
Mr Ogg, a commercial fishing boat captain, describes himself as a conservationist who doesn’t want to see whales harmed.“Fishermen have a big motivation to protect the natural environment,” he said, “because that’s where they make their living.” Previously, the challenge was adapting to changing conditions and fishing regulations on short notice, especially for smaller business owners and their crews.“One of the biggest problems we had was the unpredictability,” Mr Ogg said, “We were living from week to week then.”
Though scientists have shown the Habitat Compression Index can now forecast months in advance, state officials would probably wait to see conditions in real time before making decisions about the crab fishery, said Ryan Bartling, an environmental scientist at the California Department of Fish and Wildlife.

10 . My kitchen may be the best kitchen on the planet. That is because when I look out of its window can see the west side of Grandeur Peak. Grandeur Peak is one of the most attractive mountains in central Wasatch, with its animals, trees, morning clouds, evening sunset, and the mountain’s paragliders (滑翔伞运动员).
The number of paragliders flying above Grandeur Peak has grown over the past 15 years, so much so that they have become part of the mountain. But during the past year they have largely disappeared. Some paragliders told me that the wind became too strong to fly in. The wind is too strong! Is this another character of our changing climate (气候)? Will paragliding be a sport affected by a warming planet? Utah has been much windier in the past few years. For me, a scientist who studies living things, it is easy to believe that our future will be windier. This year it’s getting super-hot, and the planet is warming faster than scientists expected. I can’t help but worry that the future of paragliding in Utah is not bright.
I’m writing to the brave people who fly from Grandeur Peak with beautiful wings. I want you to join Clean The Dam Air, a group that’ s working hard to fight climate change and air pollution — I’m part of it too. We are introducing a measure, which aims to remove the state sales tax (税) on grocery store food and put a carbon tax on fossil fuels (化石燃料) in its place: gas, electricity produced from fossil fuels, and natural gas. The goal isn’t to make taxes higher. The idea is to encourage everyone to reduce their use of fossil fuels. So, paragliders, join us. Now is the time to take care of our planet. If we succeed, then Utah can be an example to others in fighting climate change.
