CHINA EMERGES AS TOP EMITTER CHALLENGING GLOBAL CLIMATE RESPONSIBILITY

For years, wealthy nations like the U.S. and Europe have been primarily responsible for global warming, but China’s rapid growth is shifting that dynamic. Over the past three decades, China has become the largest emitter of greenhouse gases, surpassing Europe as the second-largest historical emitter. Although the U.S. has released more emissions over time, China’s emissions are quickly catching up. China has pledged to peak emissions this decade and invest heavily in renewable energy, but its historical emissions will soon match the U.S. As global leaders meet at the UN climate summit, there’s debate about climate finance responsibility. Wealthy nations have traditionally provided aid, but China, now a major economy, is being asked to contribute more. While China points to its existing aid contributions, critics argue for more transparency. Emissions per capita also factor into the debate, with poorer nations like India asking for more time to develop. (New York Times)

SCIENTISTS CAN REBUILD PUBLIC TRUST WITH INTELLECTUAL HUMILITY

A study published in Nature Human Behavior suggests that scientists can rebuild trust lost during the COVID-19 pandemic by displaying intellectual humility. Public trust in scientists has declined since 2000, with Pew Research showing a drop from 87% to 73% by October 2023. The study, which includes five sub-studies, explores how intellectual humility—the acknowledgment of one’s knowledge limitations and openness to others’ ideas—affects public trust. Researchers found that scientists perceived as intellectually humble were more trusted and their views on topics like climate change, vaccinations, and genetically modified foods were more supported. Furthermore, the study showed that scientists’ willingness to admit gaps in knowledge increased trust, while overconfidence or unwillingness to revise views led to distrust. The study concludes that while more research is needed, intellectual humility can be a key strategy for regaining public confidence in science. (Ars Technica)

WYOMING JUDGE STRIKES DOWN ABORTION BAN IN VICTORY

A Wyoming state judge, Melissa Owens, struck down the state’s ban on abortion and its prohibition on abortion medication, marking a victory for abortion rights advocates. The laws, which were challenged by women and nonprofit organizations, restricted abortion to cases where a woman’s life is at risk or in instances of rape and incest, and banned abortion pills. Owens ruled that these laws violated women’s rights under the state constitution, specifically an amendment granting residents the right to make their own health care decisions. The decision follows a series of victories for abortion rights supporters in various states, including Missouri, Arizona, and Colorado, while some states like Florida and South Dakota upheld abortion bans. This ruling is part of a larger legal battle over abortion rights after the U.S. Supreme Court overturned Roe v. Wade in 2022, leading to stricter abortion laws in many Republican-controlled states.

MAYOR ADAMS DECLARES DROUGHT WARNING AS NYC FACES WATER SHORTAGES

Mayor Eric Adams declared a drought warning for New York City on Monday due to persistently dry conditions, which have left upstate reservoirs at 60% capacity, 19% below normal. The city has experienced a rainfall deficit of over 8 inches in the past three months. The drought warning, which follows a drought watch declared earlier in November, triggers water-saving plans from city agencies, including reduced bus and train washing by the MTA, outreach to restaurants by the Department of Health, and water restrictions for park fountains. The dry conditions have also led to an increase in brush fires, with over 300 reported in the past month. To address water shortages, work to repair a leak in the Delaware Aqueduct, which supplies 90% of the city’s drinking water, has been postponed. Officials urged residents to conserve water and take steps to minimize exposure to smoke from local fires. (The City)

DELHI SEEKS CLOUD SEEDING TO COMBAT SEVERE AIR POLLUTION CRISIS

As Delhi faces “severe” air quality levels, with the air quality index reaching nearly 500 in some areas, the Delhi Government has requested permission from the Centre to use cloud seeding to combat pollution. Cloud seeding is a weather modification technique that involves adding substances like silver iodide, dry ice, or potassium iodide to clouds to induce rainfall. These agents help water droplets form or ice crystallize, leading to precipitation. While experts believe artificial rain could help wash away pollutants, the effectiveness in Delhi is uncertain. SN Tripathi, Dean of Kotak School of Sustainability at IIT Kanpur, cautioned that cloud seeding requires optimal weather conditions, significant experimentation, and numerous clearances. He doubts it will provide immediate relief, especially with Delhi’s current air quality crisis, suggesting the process has a low probability of success at this stage. (NDTV)

EUROPEAN TECH STARTUP FUNDING PROJECTED TO DECLINE FOR THIRD YEAR

Venture capital investment in European tech startups is projected to decline for the third consecutive year, with an expected $45 billion in funding by the end of 2024, slightly lower than last year’s $47 billion. Despite this, Atomico’s “State of European Tech” report indicates that the region’s tech funding has stabilized, even amid global economic challenges. Over the past decade, European startups have secured $426 billion, far exceeding the $43 billion raised in the prior decade. However, Europe still faces challenges in areas like regulation, access to capital, and scaling across its fragmented market. Pension funds in Europe, for example, invest only 0.01% of their $9 trillion assets in venture capital, limiting exposure to fast-growing startups. Atomico is optimistic about the future, predicting that by 2034, Europe’s tech ecosystem could be worth $8 trillion and will produce its first $1 trillion tech company, similar to the U.S. tech giants.

RESEARCHERS DISCOVER PRESERVED SABER-TOOTHED KITTEN IN SIBERIA

For the first time, researchers have discovered a preserved saber-toothed kitten, providing new insights into these iconic predators. Found in Siberia’s permafrost in 2020, the frozen carcass of the Homotherium latidens kitten, which lived 35,500 to 37,000 years ago, contains its head, forelimbs, and front body. Radiocarbon dating shows the kitten was about 3 weeks old when it died. The body, remarkably well-preserved, still has thick, soft fur, broken whiskers, footpads, and sharp claws. This discovery offers valuable information about the soft tissue anatomy of these prehistoric big cats, which had a similar build to modern African lions but with shorter bodies and longer limbs. Notably, the kitten’s neck was much thicker than that of a modern lion, providing further insights into its adaptation to a snowy environment. This find helps to better understand the appearance and anatomy of saber-toothed cats that had previously been speculated from fossil bones. (Science)

GOOGLE SCHOLAR MARKS 20TH ANNIVERSARY AMIDST AI COMPETITION

Google Scholar, the largest scholarly search engine, celebrates its 20th anniversary this week. It has become an essential tool for researchers due to its vast database, free access, and ability to locate full-text articles behind paywalls. However, recent years have seen the rise of AI-powered competitors like Semantic Scholar, OpenAlex, and Consensus, which offer advanced features such as AI-generated summaries and the ability to download data, which Google Scholar does not provide. Despite these advancements, Google Scholar’s size and comprehensive coverage keep it entrenched in the scientific community. Critics point to its lack of transparency, particularly regarding its algorithms and search content, and the restriction of bulk downloads. While Google Scholar has integrated some AI capabilities, like semantic search and AI-generated article outlines, it hasn’t yet solved the challenge of providing concise, AI-generated overviews of search results. Despite emerging competitors, Google Scholar’s dominance in scholarly searches remains strong. (Nature)

NASA AND ROSCOSMOS DISAGREE OVER CAUSES OF ISS AIR LEAKS

NASA and Russia’s space agency, Roscosmos, are at odds over the causes and risks of persistent air leaks in the International Space Station’s (ISS) Russian Zvezda service module. The leaks, first identified in 2019, have increased in severity, leading to the highest risk classification in the ISS risk management system. NASA believes the cracks are caused by a combination of factors like pressure, mechanical stress, and material properties, while Roscosmos attributes them to high cyclic fatigue from micro-vibrations. Despite ongoing repairs, the leak rate has not been fully eliminated, and there are disagreements about the potential for catastrophic failure. While Roscosmos maintains operations are safe, NASA has expressed concerns about the structural integrity of the PrK transfer tunnel. If the leak becomes unmanageable, the crew may have to permanently seal the hatch, eliminating one of the Russian docking ports. Both agencies are working to resolve the issue, with NASA bringing in independent experts for further analysis. (Ars Technica)
