2 . Massive snowstorms and a blast of chilly air swept across northern China in the first week of November, leaving many people shivering(颤抖)in the freezing cold.
At the same time, a global conference on climate change-COP 26-was held in Glasgow, Scotland, where the key topic was how to curb(抑制)the trend of global warming. So why are we experiencing such a frigid(寒冷的)winter on a warming planet? The cold snap(寒潮)and global warming, two seemingly opposing forces, are not contradictory, Zhou Bing, chief expert at the China Meteorological Administration’s National Climate Center, told China Daily.
Against the backdrop of a warming planet, China has seen a growing average temperature in winter, which has increased by 0.41°C every decade since 1961, according to Zhou. But in some cases, the country has also experienced freezing cold-for instance, the icy weather that hit the country in early 2008. Global warming does not appear evenly, but triggers more extreme heat and cold, Zhou explained. Global warming has changed the patterns of Earth’s atmospheric circulation, affecting the local climate via sea-air or land-air interaction. In October, La Nina, the periodic(周期的)cooling of ocean surface temperatures in the central and east-central equatorial(赤道的)Pacific, started to affect China, bringing more cold air to the country, said the National Climate Center. Between 1951 and 2020, a total of 15 La Nina events occurred in China. Ten of them brought lower-than-average winter temperatures, according to the National Climate Center.
Another reason for the chilly weather is the warming Arctic, according to the BBC. The Arctic is warming two to three times as fast as any other place on Earth, said Zhou, adding that the polar vortex, a rotating(旋转的)pool of cold, dense air weakens as the temperature goes up, pushing the cold Arctic air southward. So will this winter be particularly cold? Unlike a series of cold waves that cool down the nation gradually, people will experience the quick-freeze effects several times, and a cold winter is likely, a Beijing-based climate expert told the Global Times.
The official forecast also said that northern China will see more snow than average and southern China less rainfall than average.

5 . Millions of migratory(迁徙的)birds occupy seasonally favorable breeding(繁殖)grounds in the Arctic, but scientists know little about the formation, maintenance and future of the migration routes of Arctic birds and the genetic determinants of migratory distance. In a new study, a multinational team of researchers under the leadership of Dr. ZHAN Xiangjiang from the Institute of Zoology of the Chinese Academy of Sciences integrated two state-of-the-art techniques-satellite tracking and whole genome sequencing(基因排序)-and established a continental-scale migration system of peregrine falcons in Eurasian Arctic.
The researchers tracked 56 peregrine falcons from six Eurasian Arctic breeding populations and sequenced 35 genomes from four of these populations to study the migration of this species. They found that the birds used five migration routes across Eurasia, probably established between the last Ice Age 22, 000 years ago and the middle-Holocene 6, 000 years ago. “Peregrine falcons initiated their autumn migration mainly in September, and arrived at their wintering areas mainly in October, " said Professor Mike Bruford, an ecologist at Cardiff University. “Peregrine falcons that depart from different breeding grounds use different routes, and winter at widely distributed sites across four distinct regions. Individual birds that were tracked for more than one year exhibited strong path repeatability during migration, complete loyalty to wintering locations and limited breeding dispersal(扩散). ”
The researchers quantified the migration strategies and found that migration distance is the most significant differentiation. They used whole genome sequencing and found a gene-ADCY8, which is known to be involved in long-term memory in other animals in previous research- associated with differences in migratory distance. They found ADCY8 had a variant at high frequency in long-distance migrant populations of peregrine falcons, indicating this variant is being favorably selected because it may increase powers of long-term memory thought to be essential for long-distance migration.
“Previous studies have identified several candidate genomic regions that may regulate migration-but our work is the strongest demonstration of a specific gene associated with migratory behavior yet identified, ”Professor Bruford said. The researchers further looked at models of likely future migration behavior to predict the impact of global warming. If the climate warms at the same rate as it has in recent decades, they predict peregrine populations in western Eurasia have the highest probability of population decline and may stop migrating altogether.
“Our work is the first to begin to understand the way ecological factors may interact in migratory birds, ” said Dr. ZHAN Xiangjiang. “We hope it will serve as a cornerstone to help conserve migratory species in the world. ”

6 . The cumulative rainfall in Henan province during the four days was the highest since the province has records, the provincial meteorological service said. The rain was heaviest in the provincial capital, Zhengzhou, for a short period on Monday and Tuesday. Northern, western and central parts of Henan also experienced downpours, the service said. Zhengzhou's biggest one-hour precipitation (降水量) —201. 9 mm between 4 and 5 pm on Tuesday—was also the highest on the Chinese mainland. The previous record was 198. 5 mm in the village of Linzhuang in Zhumadian in August 1975, the National Meteorological Center said. The city's precipitation during the four days exceeded that of its average annual precipitation, the center said.
Chen Tao, chief forecaster at the National Meteorological Center, said abundant water vapor (水蒸气) brought by Typhoon In-Fa and the province's special geographical features led to Henan's rain. “Partly affected by the typhoon, large amounts of water vapor have been transported to China's inland areas, including Henan,” he said.
From Thursday to Monday, rain was forecast to continue in Henan. However, rainfall will gradually subside in Zhengzhou and the province's northern and central regions, though the storms will increase the risk of mountain torrents and other geological disasters. By Monday, lighter rain is forecast for parts of Henan, the provincial weather service said. However, local authorities are still urged to be vigilant and prepare to prevent or cope with flooding and other possible disasters.
Predicting such weather events remains a challenge worldwide because it involves many meteorological phenomena, the center said. “The formation of this kind of extreme weather, including rainstorms and high temperatures, is complex,” Chen said. “We still lack effective solutions and methods for such forecasting”, he said. “We are now putting a lot of effort into tackling the difficulty. We believe that as the technology improves, we can better forecast the events.”

7 . In January 1958, Rachel Carson received a letter from her fiend Olga Owens Huckins. Huckins lived in an area of Massachusetts where the state was trying to get rid of mosquitoes. They had used planes to spray a mixture of fuel oil and DDT (a pesticide, which can kill pests such as insects, weeds and rodents) all over the area around Huckins home. DDT was supposedly harmless but the morning after the spraying. Huckins found several of her favorite birds dead outside her house. And the spraying did not even kill all of the mosquitoes, in fact that summer there were more of them than ever before. Huckins asked Carson if she knew someone in Washington that could help prevent future spraying.
Carson had been hearing about DDT since a Swiss chemist discovered it could be used to kill insects in 1939. To many people, DDT seemed like a miracle substance. Farmers were excited about saving their crops from pests. Doctors and others were excited about saving people's lives by killing disease-carrying insects. But to Carson. DDT appeared to be dangerous to all living creatures.
The more Carson found out about DDT and other pesticides, the more she realized that she needed to help stop future spraying. Carson decided to write a book about pesticides. She said, “There would be no future peace for me if I kept silent.” She called her book Silent Spring.
Carson had spent her life studying, observing, and writing about nature. She was a trained biologist and a talented writer who knew how to present scientific information in compelling stories. Before Silent Spring, she had written other books from the perspective of fish birds, islands and oceans. Carson knew that all things in nature exist in a delicately balanced ecosystem. In Silent Spring, Carson wrote that. although the ecosystem can adjust to changes, it needs time. Carson believed that people u the 1950s were using pesticides carelessly Nature didn’t have time to adjust, wrote Carson, because so any pesticides had been used in such large quantities in such short tame.
