2 . In the middle of the night, a baby chimpanzee (黑猩猩) is having nightmares. Chantal, his caretaker, tries to calm him down. She works at the Tchimpounga Chimpanzee Rehabilitation Center, in the Republic of the Congo, in Africa. The chimp’s name is George. He was taken from his mother by hunters. Finally, he was rescued and taken to the sanctuary (鸟兽保护区), where Chantal helped him make friends with other chimpanzees. “We rescue chimps from terrible conditions and help them to live in the wild like other chimpanzees,” Chantal said, “They need to learn chimp behavior.”

Chimpanzees meet a lot difficulties because people cut down forest and illegal (非法的) wildlife trade. Their population, numbering in the millions a century ago, could be down to 172,000. This makes the work of the Tchimpounga Sanctuary even more important.

When opening in 1992, Tchimpounga had space for 60 chimpanzees. It has been made larger to the size of a hundred football fields, and provide home around 150 chimps. Many live on islands with thick forest in the Kouilou River. In that environment, the chimps are prepared for a possible return to the wild. The sanctuary also works with the government to reduce illegal trade in animals. Tchimpounga’s head veterinarian (兽医) Rebeca Atencia said, “We have effectively reduced the arrival of orphan (孤儿) chimpanzees to Tchimpounga. We’ve received only one orphan chimp over the past three years.”

The chimps have shown that they understand the sanctuary staff’s efforts. “Saving the life of a chimpanzee is very gratifying,” Atencia says. “Chimpanzees know when you’re helped them or saved their life. Sometimes, they thank you with a hug.”

As the leader of Jane Goodall Institute (JGI), Atencia also works with people who live near the sanctuary. These people depend on the forest for food and building houses, and their growing population is a danger to chimps. JGI helps the people in these places get healthcare, clean water, and others. This makes them less dependent on the area’s natural resources and reduces illegal trade in chimps. At present, there are islands within the sanctuary where the chimps can be safe from wild chimpanzees and hunters. And they’ re still under the care of the sanctuary staff.

4 . Construction of Project Nexus is scheduled to be completed by the end of 2023. The 5-megawatt project will consist of three sites along canals in central California with widths ranging from 20 feet to 100 feet.

If the pilot project proves solar canopies(檐篷) are a cost-effective way to produce clean energy and save water, scores of similar installations could be built atop California’s canal network-one of the world’s largest water distribution systems.

“This is a really exciting project,” California Natural Resources Secretary Wade Crowfoot said last month. “It connects our efforts in California to improve water conservation and build drought resilience(抗旱能力) with the clean energy transition we're driving across California.”

Project Nexus was inspired by a 2021 study by University of California researchers that was published in the journal Nature Sustainability. Typically, 1%to 2% of the water that circulates through California's canals evaporates(蒸发), a number that is expected to increase due to the climate crisis.

Using data from satellites, climate models, and automated weather stations, the peer-reviewed study estimated that covering all of the approximately 4, 000 miles of California’s canals could extremely reduce evaporation, saving 63 billion gallons of water annually —comparable to the amount of water required to irrigate 50, 000 acres of farmland or meet the water needs of more than 2 million people.

Governor Gavin Newson has allocated additional funds to help local communities cope with water scarcity and encourage Californians to use less water. “Research and common sense tell us that in an age of intensifying drought, it's time to put a lid on evaporation,” said Jordan Harris, CEO of Solar AquaGrid, the company that is building the solar canopies.

The study found solar canals would be able to generate 13 gigawatts of clean power, equal to approximately one-sixth of the state's current installed solar capacity. This additional generation could help California achieve its goal of supplying at least 60% of its electricity from renewable sources by 2030 and 100% by 2045.

9 . Nearly every nation is coming up short — most of them far short — in their efforts to fight climate change, and the world is unlikely to hold warning to the internationally agreed-upon limit, according to a new scientific report.

Gambia, a tiny country in Africa, is the only nation that is cutting emissions (排放) and taking up its share of actions to keep the world from exceeding the Paris Agreement’s goal of limiting warming to 1.5℃ above preindustrial times, according to the report. Only one industrialized nation — the United Kingdom—is even close to doing what it should to cut emissions of heat-trapping gases and finance clean energy for poorer nations, the Climate Action Tracker(CAT)reported.

Enough nations promised big enough carbon pollution cuts that the CAT said the “emissions gap” — the difference between emissions projections (预测) with the promises and what’s required to meet the 1.5-degree goal — dropped by 11%.

“That momentum (势头) has not been maintained,” said Bill Hare, report co-author and CEO of Climate Analytics. “We’re running short of countries stepping up with additional emission commitments to close the gap.”

Unlike its previous reports, which just looked at promises to cut carbon pollution and policy changes, the new ratings include money issues. Finance is critical to climate negotiations this fall in Scotland, so the report examined commitments by rich nations to help pay for clean energy for poor nations, according to Hare.

That hurt the United States and European Union rankings. The report called efforts by the United States, the European Union, Germany and Japan “insufficient” and more in line with global warming of 3℃ since the late 19th century. The world has already warmed by 1.1℃ since that time, so these countries will make the world 1.9℃ warmer than it is now.

Hare said Brazil and Mexico “went backwards” on their fight to control warming. The report lists Iran, Russia, Saudi Arabia, Singapore and Thailand at the bottom.

10 . All types of marine life are important. Seaweed (海藻) and corals both play vital roles in the health of the ocean and the health of our communities.

However in the same way that a mountain lion. Which provides a valuable service by hunting diseased or elderly deer, wouldn’t be helping anyone if it took up residence in an office building. Seaweed largely prevents corals from performing their key function in the ecosystem, just like the lion would prevent any of the terrified office workers from doing their work.

There is long-standing competition between seaweed and corals and this competition has been influenced heavily for over a century by overfishing climate change, and coral discases, which resulted in corals being now too weak to compete with seaweed.

Seaweed too often is blocking sunlight from reaching baby corals, while releasing chemicals that prevent corals from reproducing-as well as making them marc likely to be attacked by diseases.

The researchers from Florida International University supposed that if sufficiently distributed, the Caribbean king crab (蟹), lovingly called the “reef (礁)goat”, could make coral reefs free of seaweed fast, so they conducted a case-control study where they released the crabs on some reefs and let some others remain crab-less.

Eating seaweed at a rate higher than any other grazer (食草动物), the crabs were able to reduce seaweed cover by 80%, while a 3 to 5 fold increase of both baby corals and fish species added to the successful outcome.

On dry land, goats have been used as ground clearers for thousands of years, as they eat everything from clover and grasses to poison oak and invasive blackberry thorns. Hopefully, the results of this study can solidify Caribbean king crabs as their equivalent at the bottom of the sea.
