A composting (堆肥) program at The Wesley School in Los Angeles is helping students get hands-on experience and ways     1     (handle) human-driven climate change. For the past year, all the leftover food waste from the school has gone into composting containers rather than a landfill     2     it would be buried and would produce planet-warming gases.

The school’s composting program     3     (come) into being in 2022, and this year, the school held a     4    （celebrate) to reveal what happened inside a series of five-foot-tall containers. Steven Wynbrandt, a local farmer     5     composting consultant who has helped the school with its program, broke the ties that held the container closed. Rich black compost spilled out from the container.

The school will use the compost on plants around campus. Some will     6     (offer) to families that want to use it at home, and whatever is left will be donated.

It takes two hours for the container to be emptied and prepared to receive     7     next day’s lunch leftovers. The other containers remain full of food waste that is in the process of     8     (break) down. Decorated     9     (poster) on the outside of each container indicate when they can be opened so that the next generation of plants on campus can benefit     10     the rich soil.

China drives world renewables capacity addition in 2023

China was the major driving force behind the world’s rapid     1     (expand) of renewable power generation capacity last year, which grew by 50 percent to 510 gigawatts, the International Energy Agency said.

    2     (drive) by rapid growth in China, renewable energy capacity surged globally last year, generating green power faster than at any time during the last few decades. China, which has become     3     dominant force in the field of renewable energy,     4     (see) its position further consolidate in the next five years, as lower costs make utility-scale solar power generation more attractive compared to coal and gas power generation.     5     (additional), China has outlined and clarified regulations for green power certificates,     6     will bring additional income for solar and wind energy developers, and further accelerate its renewable energy development.

China’s installed capacity of renewable energy exceeded 1.45 billion kilowatts in 2023,     7     (account) for more than 50 percent of the country’s total installed power generation capacity. Power generated from renewable energy sources such as wind and solar now accounts for more than 15 percent of China's total electricity consumption.

China has several advantages that others do not possess, including the ability     8     (approve) and build transmission grids and renewable energy projects     9     (efficient) and finance projects more easily thanks    10     policy priorities.

5 . Using CRISPR genome (基因组) editing on a few common crops, a team of plant and soil scientists seeks to greatly increase and speed up carbon storage to help fight climate change.

To prevent dangerous levels of global warming, scientists say it won’t be enough to just stop burning fossil fuels that release carbon into the air. Because it’s nearly impossible for humanity to do that as fast as is now required, we will also need to pull carbon out of the air and secure it.

Plants are among the best tools we have to do this, since these living solar collectors already capture billions of tons of carbon dioxide each year from the atmosphere through photosynthesis (光合作用). About half of that carbon winds up in roots and eventually the soil, where it can stay for hundreds to thousands of years.

But what if we could create plants and soils that are better at capturing carbon? With CRISPR genome editing—a new molecular (分子的) biology tool that allows scientists to make edits to the DNA code that underpins all life—that might be possible.

Last month, the Innovative Genomics Institute (IGI), a research team founded by CRISPR pioneer Jennifer Doudna, began to explore the idea. With an $11-million donation from the Chan Zuckerberg Initiative, a team of researchers made a three-year effort using CRISPR to create new crop varieties that photosynthesi ze more efficiently and transport more carbon into the soil. Eventually, the researchers hope to create gene-edited rice and sorghum seeds that could—if planted around the globe--pull more than a billion extra tons of carbon out of the air annually.

It’s an ambitious goal, and the team is likely to face numerous challenges in the lab before its CO2-cleaning plants can be put in the ground. Additional social, policy, and ethical considerations will determine whether those crops are widely accepted by farmers. But the researchers believe their ambitious project is beneficial to cope with climate crisis.

6 . From solar panels to electric cars, clean energy has become a bigger part of our lives in recent years. A new report from the International Energy Agency (IEA) predicts that it will only develop a stronger foothold in the decades to come, with more solar panels, electric cars, and renewable energy by 2030.

The IEA analyzed the current policies and added that there will likely be two-thirds more clean energy ten years from now with a decreased dependence on fossil fuels. “The transition to clean energy is happening worldwide and is unstoppable. It’s not a question of ‘if’, but a matter of ‘how soon’—and the sooner, the better for all of us,” says the IEA Executive Director Fatih Birol.

“Governments, companies, and investors must support clean energy transitions rather than hinder them. There are immense (巨大的) benefits on offer, including new industrial opportunities and jobs, greater energy security，cleaner air, universal energy access and a safer climate for everyone. Considering the ongoing strains and volatility (波动) in traditional energy markets today, claims that oil and gas represent safe or secure choices for the world’s energy and climate future look weaker than ever,” Biral adds.

Although this is welcome news for many, the IEA stresses that more improvement will be needed for the 200 countries in the Paris Agreement to meet the goal of limiting global warming to 1.5 degrees Celcius (34.7 degrees Fahrenheit). Governments must triple renewable capacity, reduce methane emissions from fossil fuel operations by 75%, and triple clean energy in developing economies.

“Every country needs to find its own pathway, but international cooperation is crucial for accelerating clean energy transitions,” Birol asserts. “In particular, the speed at which emissions decline will be largely determined by our ability to finance sustainable solutions to meet rising energy demand from the world’s fast-growing economies. This all points to the importance of redoubling cooperation, not retreating (逃避) from them.”

Ar Horqin Grassland Nomadic System in the Inner Mongolia autonomous region, listed on the list of Globally Important Agricultural Heritage Systems by the United Nations,     1     (demonstrate) the wisdom of herdsmen to work in harmony with nature.

The     2     (season) movement of herds among different pastures (牧场) plays an important role in maintaining the self-renewal and recovery     3     (capable) of the grasslands. While keeping soil fertility from degrading, the nomadic lifestyle can protect vegetation and make good use of water resources,     4     the growing population of people and livestock, still puts much pressure     5     the grassland resources. Locals have, therefore, come up with ways to avoid overgrazing. With ancestral wisdom     6     (root) in a time of relatively small societies, it may be unable to solve issues today. This is     7     modern planning can help with.

For example, since 2015, under the guidance of the local government of Ar Horqin Banner, the number of sheep and goats in the nomadic system     8     (reduce) from 390,000 to 190,000, while the number of cattle has been increased from 40,000 to 81,000 head. No more than 100,000 sheep are allowed to migrate to the summer camps every year. With     9     (scientific) designed grazing patterns ensuring sustainable development of the grasslands, herdsmen can maintain     10     more balanced relationship with nature.

8 . A new study by the Zoological Society of London has found that nearly one in five of the world’s 10,000 species of reptiles (爬行动物) are threatened with extinction. The study, which has been printed in the journal Biological Conservation, was carried out by more than 200 experts who assessed the risk of extinction of 1,500 reptiles selected at random from around the globe.

The primary author of the paper, Monika Bohm, explained to the Zoological Society:” Reptiles are often associated with extreme habitats and tough environmental conditions, so it is easy to assume that they will be fine in our changing world. “However, that’s far from the truth:” Many species are very high specialized in terms of habitat use and the climatic conditions they require for day to day functioning, “Bohm said.” This makes them particularly sensitive to environmental changes. “The paper highlights three critically endangered species in its research, including the jungle runner lizard Ameiva vittata, which has only ever been spotted in the Cochabamba region of the Bolivian jungle—an area under threat from the growth of agriculture and logging. The two most recent searches for the species have been unsuccessful. Meanwhile in Haiti, six of the nine species of Anolis lizard in the country risk extinction due to increasing deforestation (毁林).

Also at risk are freshwater turtles, with 50% of all species at risk of extinction from hunting; turtle parts are in high demand as ingredients in traditional medicine. According to the study 30% of freshwater reptile species are also in danger of completely disappearing.

Reptiles have a long evolutionary history: snakes, lizards, crocodiles and tuataras first appeared on earth around 300 million years ago. They are an important part of many ecosystems. ”This is a very important step towards assessing the conservation status of reptiles globally, “Philip Bowles from the IUCN Species Survival Commission said in response to the study.” Tackling the identified habitat loss is key conservation priorities in order to transfer declines in these reptiles.”
