1 . Nature has the power to alter an element’s identity with time and space. This is evident by the transformative effect Britain’s deep coal mines have been showing after decades of being one of the biggest reasons for pollution. Now, they’re being employed to supply green energy to the town of Gateshead. The town is the first place to experience something like this in the country, but the success of the phenomenon has encouraged the authorities to apply it to other towns.

In 2021, coal was just producing 2% of electricity in the UK. Most of the electricity in the country is being supplied through oil and gas. This has resulted in massive abandoned coal mines all across the country. As years went by, these mines were flooded with water, making it a source of geothermal（地热的） energy, which is used to generate heat and electricity. Gateshead hosts such a mine in its town, whose council, therefore, launched a mine water project in March 2023.

The authorities put in a large central heat pump in the mine. Mine water can often sit with a temperature of 45℃. The water is then pumped using appliances to home heat pumps. The process increases the temperature further. The water then goes ahead and warms up the interior space and home water supply. After the heat from the water has been used, it’s sent back to the mine where it again goes through the same process. The project has been successful in supplying low-carbon heating to 350 high-rise buildings, a college and several office buildings.

“Recovering heat from mine water below the ground within abandoned coal mines provides an exciting opportunity to generate a low-carbon secure supply of heat, benefitting people living or working in buildings on the coalfields,” said Gareth Farr, head of heat and by-product innovation at the Coal Authority.

The water resources through the mines are estimated to be two billion cubic meters or half the amount of water in Loch Ness. Farr added, “With many millions of people living upon abandoned coalfields in Great Britain, the potential for mine water heat could be significant.”

2 . “The era of global warming has ended and the era of global boiling has arrived,” the UN secretary general, Antonio Guterres, said after scientists confirmed July 2023 was the world’s hottest month on record.

“Humanity is in the hot seat,” Guterres told a press conference on Thursday. “For vast parts of North America, Asia, Africa and Europe, it is a cruel summer. For the entire planet, it is a disaster. And for scientists, it is clear that humans are to blame. Climate change is here, it is terrifying, and it is just the beginning. The era of global warming has ended; the era of global boiling has arrived.”

Guterres urged politicians to take swift action. “The air is unbreathable, the heat is unbearable, and the level of fossil fuel profits and climate inaction is unacceptable. Leaders must lead. No more hesitancy, no more excuses, and no more waiting for others to move first. There is simply no more time for that.”

“It is still possible to limit global temperature rise to 1.5℃and avoid the very worst of climate change but only with dramatic, immediate climate action. We have seen some progress, but none of this is going far enough or fast enough. Accelerating temperatures demand accelerated action.”

The WMO secretary general, Petteri Taalas, said, “The need to reduce greenhouse gas emissions is more urgent than ever before. Climate action is not a luxury but a must.”

Other climate scientists confirmed the findings. Karsten Haustein at Leipzig University found the world was 1.5℃ hotter in July 2023 than in the average July before industrialisation.

Marina Romanello, a climate and health researcher at University College London, said, “We have data showing how the very foundations of health are being undermined by climate change. But we still have time today to turn the tide and to ensure a liveable future for us and our children.”

3 . Sounds from human activity flood across the oceans, causing trouble to ocean creatures. And climate (气候) change may make some places even louder.

Researchers have expected the oceans to get noisier because of increasing human activity. “The more goods you buy, the more shipping you have, so the more noise you have.” says Luca Possenti, a scientist studying sound in the ocean at the Royal Netherlands Institute. But Possenti and his co-worker realized that climate change might also influence how sound travels through the water.

Human-caused climate change is changing ocean temperatures, salt levels and acidity (酸度). So Possenti’s team used computers to model how those factors (因素) influence noise levels across the world’s oceans.

When waters become more acidic, they can’t take in sound at some wavelengths as well, so those sounds can travel further, adding to the noise in some areas. This effect is relatively small. Other changes impact the sound level more, the researchers found. Changes to temperature and salt levels can change how well different layers (层) of the ocean mix, which, in turn, impacts how sound travels.

The team predicted (预测) models of the world in about 70 years if climate change continues. And then they compared them with models of the world now. In the North Atlantic, they saw an increase in sound levels in the upper 125 meters of the ocean. This was caused mostly by ice melting (融化) off of Greenland, forming a cold layer of water near the ocean’s surface. Sound traveling through water tends to go toward the coldest area. As a result, sound waves tended to get stuck in the cold top layer-spreading further out across the water, instead of traveling deeper. That increased the noisiness at this depth in the North Atlantic. The models suggested that a single ship could sound about five times as loud underwater because of this. Considering all the ship traffic between Europe and North America, that may stress animals, many of which communicate, and catch food with sound.

4 . Low-effort things you can do to live sustainably

You might think you need to change a lot of your daily habits to live sustainably but, in fact, becoming more eco-friendly is much easier than it might seem. Below are some easy steps towards becoming more sustainable.

Shop at farmer markets.

Getting your daily fruit and vegetables from a local farmer market is an easy way to reduce your carbon footprint while eating healthily. It cuts out lengthy stays of the products in refrigerated storage and up to thousands of miles of fossil-fueled transportation.     1    

Practice meatless Mondays.

Global meat production is a big contributor to greenhouse gasses.     2     It isn’t necessary either. Many people reducing their meat consumption by a small amount would still have a great impact. According to a study, you could reduce your carbon footprint by as much as 8 pounds each week just by practicing meatless Mondays only.

Dispose of unused medications properly.

Flushing (冲) unused medications down the drain (下水道) can pollute water supplies affecting everything downstream. You shouldn’t throw medications away either as they can be dangerous for others to find.     3     Leftover medications can be chemically dealt with and disposed of in a safe and secure way there.

It is easy to understand that buying something used is more environmentally friendly than buying something new and clothes are no exception.     5     According to the United Nations, the fashion industry is responsible for 2% - 8% of global carbon emissions (排放量). Buying something used keeps things out of landfills and reduces demand for new items.

9 . 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 has 300 earthquake stations and over six years worth of continuous records, making it an ideal location 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.

10 . When Hurricane Ian hit Florida, Karen Lauder refused to leave her home because she was wrong about the intensity(强度) of the storm. Karen is 84 years old and depends on a wheelchair to get around because she is missing a leg. Her son, Johnny Lauder, tried repeatedly to get her to leave, but she refused.

Johnny and his whole family live within a few blocks of one another. They kept in touch with Karen as the storm continued violently(猛烈地) outside, watching the water rising dangerously all around them. When Karen reported that the water in her house had reached her bottom, Johnny knew he had to take action.

First, Johnny ensured his sons and their pets were taken care of. Then, he jumped out of a window and began to swim. Johnny used to work as a rescue swimmer. He is obviously a strong swimmer, but the flood water was filled with dangerous materials. There was also a strong current (水流), and he had to swim against it for most of his trip to Karen’s. As he made his way through the water, Johnny stopped periodically to snap selfies(自拍) to show his worried family that he was okay.

Johnny was racing against the clock. He knew he only had a short period of time to get there before the water rose above Karen’s head. It took him 40 minutes to swim four blocks. The sound of Karen shouting inside was music to his ears!

“If it would’ve been 20 minutes later, she wouldn’t be here,” Johnny said.“She’s never been happier to see me.”

Karen is now safe, although she is in the hospital being treated for infections(感染) she got in the water. The family have all lost everything they owned, including their houses, but they’re grateful just to be here.
