1 . The world’s coral reefs do more for the planet than provide underwater beauty. They protect shorelines from the effects of hurricanes. An estimated 500 million people earn their livelihood from the fishing stocks and tourism opportunities reefs provide. The tiny animals that give rise to reefs are even offering hope for new drugs to treat cancer and other diseases.
Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. So now scientists around the world are looking for all kinds of ways to protect and maybe even revive(复苏) corals. In the Bahamas, Ross Cunning, a research biologist at Chicago’s Shedd Aquarium, is focusing on corals with genes that could make them natural candidates for restoration projects. He recently published a study of two Bahamian reefs, one that seemed to survive an intense 2015 heat wave, and one that didn’t.“It sets the stage to find out which genes are responsible for thermal tolerance,” says Cunning, adding that he hopes discovering those genes will help scientists one day breed more heat-tolerant coral.
In Massachusetts, Cohen’s research has found two key elements that seem to protect corals. The first: internal(内部的) waves beneath the ocean’s surface that bring cooler currents to heat-struck corals, essentially air-conditioning them as temperatures rise. The second: adaptation, a quality that corals found in Palau’s warm lagoons(环礁湖) seem to display.On average, these lagoons submerge(淹没) coral in water that is two degrees Celsius warmer than the water outside the lagoons. “We think the fact that they can deal with these higher temperatures is built into their genetics and allows them to deal with the heat waves.”
She’s also found evidence of corals evolving more quickly in the past two decades to withstand rapidly warming temperatures. The big question scientists are now enquiring into, says Cohen, is whether there’s a cap on how much more heat corals can adapt to. Cohen calls these regions with heat-adapted corals as “super reefs,” and like Friendlander, advocates for using marine reserves to protect them.

2 . New Zealand plans to put a price on sheep and cow burps (打嗝) to reduce greenhouse gas emissions (排放). If the plan is passed, New Zealand will become the first country to tax (征税) farmers on each burp of their cattle, since the burps give out methane (甲烷) into the atmosphere.
“There is no question that we need to cut the amount of methane we are putting into the atmosphere, and an effective emissions pricing system for agriculture will play a key part in how we achieve that,” Climate Change Minister James Shaw said.
Animal agriculture is one of the leading causes of global warming. It is reportedly responsible for at least 14.5% of the world’s emissions. Moreover, cows are by far the biggest contributors. This is so because they produce 40% of global methane when they burp, fart (放屁) and produce waste. Also, methane is 80 times more warming than CO2 although it’s shorter-lived in the atmosphere.
New Zealand, which has a population of five million people, has around 10 million cattle and 26 million sheep. “Almost half the country’s total greenhouse gas emissions come from agriculture, mainly methane,” the draft plan explained.
The “burp tax” is expected to take effect in 2025. Mr. Shaw wants farming to be more environmentally friendly. He also wants farmers to change the way they farm. He wants them to feed their animals on seaweed instead of grass. This will produce fewer emissions. Mr. Shaw also said farmers can reduce the tax they pay by planting more trees. Another suggestion is for cows to wear special masks.
New Zealand’s farmers support the government. They want to do their bit to help the environment.

5 . Overlooking the Davis—Gant Varsity Soccer Field, a bed of overturned soil waits for further development. In a few years, this area will become a natural habitat and a playground for animals and residents. This peaceful area didn’t appear naturally, but through planning and action taken by Catlin Gabel’s Tiny Forest project launched by teacher Patrick Walsh.
Forests typically take hundreds of years to mature, with four stages of growth. “Tiny forests flatten out time through the planting of all four layers (层),” Walsh explained. The end result is a fast-growing, native forest in about 20 years. Over 600 plants from 43 species will be planted in the tiny forest, the first one in Oregon.
Walsh was inspired to build a tiny forest after hearing about this idea, which emerged in Japan and has taken hold in North America. He shared his vision with seniors in his class. The seniors researched tiny forests and made a proposal resulting in Clean Water Services donating 60 trees and $5,000 from the National Oceanic and Atmospheric Administration. Armed with these resources, Walsh and the students started working. “Something I didn’t really expect was the outpouring of students’ enthusiasm. Seeing students from all grades volunteered to contribute to the ‘dirty work’ really blew me away,” Walsh said.
Senior Megan Cover has been at the school since the first grade. “I’ll graduate after working on this project, which is surely sad, but it’s really rewarding and great to be a part of this project and to do my bit. We’re creating this educational space for many young kids,” Cover said.
Walsh summed up his goal of the project, which is to build a place where students can enjoy and learn about nature. “The forest will obviously not solve climate change, but it will deserve the efforts if the kids think about climate change and remember the importance of reforestation and trees when they look outside at the forest.”

6 . This summer we witnessed interview teams at the North Pole wearing short sleeve shirts due to the warm weather. A study published on Aug 29 revealed more concerning issues in the supposedly coldest area of the world. Zombie ice from a massive Greenland ice sheet was confirmed to be melting, which would eventually raise global sea levels by at least 10 inches (27centimeters) on its own, reported Associated Press ( AP).
Zombie ice is the kind of ice that is still attached to thicker areas of ice, but is no longer getting fed by larger glaciers. Since glaciers are getting less snow to complement the amount of ice melted, once the zombie ice is melted, it cannot be re-formed.
Scientists decided to look at the balance of the ice. In perfect equilibrium, snow in the mountains of Greenland flows down and thickens the sides of glaciers, balancing out what’s melting on the edges, according to AP. But in the last few decades, there is less refill and more melting, creating an imbalance.
Study co-author William Colgan at the Geological Survey of Denmark and Greenland told AP that 3.3 percent of Greenland’s total ice volume will melt eventually. “Starving would be a good phrase for what’s happening to the ice,” Colgan added.
With a great number of natural resources buried under the earth, areas of melted ice revealed treasures that attracted the world’s richest men. According to CNN, in early August, there was a “treasure hunt” in Greenland. Billionaires, including Bill Gates and others, financially backed KoBold Metals, a US - based mineral exploration company, to explore the rare metals under the glaciers in Greenland. The company told CNN that since there were enough minerals to power hundreds of millions of electric vehicles, the critical resource is capable of powering the green energy transition.
While investors are taking advantage of global warming, experts express their concerns that the mineral exploration is likely to worsen the local environment, draining up the world’s resources at a faster rate.

8 . After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.
The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.
As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.
