‘Feels like summer’: Warm winter breaks temperature records in Europe

January 5, 2023126 Views

Record-high winter temperatures swept across parts of Europe over the new year, bringing calls from activists for faster action against climate change while offering short-term respite to governments struggling with high gas prices. Hundreds of sites have seen temperature records smashed in the past days, from Switzerland to Poland to Hungary, which registered its warmest Christmas Eve in Budapest and saw temperatures climb to 18.9 degrees Celsius (66.02°F) on Jan. 1. In France, where the night of Dec. 30-31 was the warmest since records began, temperatures climbed to nearly 25C in the southwest on New Year's Day while normally bustling European ski resorts were deserted due to a lack of snow. A cable car is seen on mountain Jahorina in Sarajevo, Bosnia and Herzegovina January 4,...

Skiing over Christmas holidays no longer guaranteed – even with snow guns

For many people, holidays in the snow are as much a part of the end of the year as Christmas trees and fireworks. As global warming progresses, however, white slopes are becoming increasingly rare. Researchers at the University of Basel have calculated how well one of Switzerland’s largest ski resorts will remain snow reliable with technical snowmaking by the year 2100, and how much water this snow will consume. The future for ski sports in Switzerland looks anything but rosy – or rather white. Current climate models predict that there will be more precipitation in winter in the coming decades, but that it will fall as rain instead of snow. Despite this, one investor recently spent several million Swiss francs on expanding the Andermatt-Sedrun-Disentis ski resort. A short-sighted decis...

Uneven wetting affecting Tibetan Plateau

Climate change is causing diverse variations in the thawing of frozen ground The Tibetan Plateau has experienced prominent warming and wetting since the mid-1990s that has altered the thermal and hydrological properties of its frozen ground. In a new study, published in Advances in Atmospheric Sciences, scientists used the Community Land Surface Model to uncover that the dual effect of this wetting and the projected increase in precipitation over the Tibetan Plateau in the future is becoming a critical factor in determining the thermodynamics of the frozen ground. The lead author of the study, Dr Xuewei Fang from the School of Atmospheric Sciences at Chengdu University of Information Technology in China, explains that “In the face of the greatest increase in the occurrence frequ...

Climate change threatens centuries-old oases in Morocco

Residents of the oasis of Alnif say they can’t remember a drought this bad: The land is dry. Some wells are empty. Palm groves that date back more than 100 years are barren. Home to centuries-old oases that have been a trademark of Morocco, this region about 170 miles southeast of Marrakesh is reeling from the effects of climate change, which has created an emergency for the kingdom’s agriculture. Nomadic herders guide their sheep in search for food to graze near Tinghir, Morocco, Monday, Nov. 28, 2022. (AP Photo/Mosa'ab Elshamy) Among those affected is Hammou Ben Ady, a nomad in the Tinghir region who leads his flock of sheep and goats in search of grazing grass. The drought forced him to rely on government handouts of fodder. November is usually a cold, wet month in Alnif, b...

New cause of melting Antarctic ice shelves identified

Existing conservation efforts insufficient to protect Antarctic ecosystems Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic. An international team of scientists found that adjacent ice shelves play a role in causing instability in others downstream. The study, led by the University of East Anglia in the UK, also identified that a small ocean gyre - a system of circulating ocean currents - next to the Thwaites Ice Shelf can impact the amount of glacial-meltwater flowing beneath it. When that gyre is weaker, more warm water can access the areas beneath the ice shelf, causing it to melt. Meanwhile, another study says that existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are...

Palau’s Rock Islands harbor heat-resistant corals

Finding could help reef managers to develop new defenses against ocean warming Ocean warming is driving an increase in the frequency and severity of marine heatwaves, causing untold damage to coral reefs. Tropical corals, which live in symbiosis with tiny single celled algae, are sensitive to high temperatures, and exhibit a stress response called bleaching when the ocean gets too hot. In the last 4 decades, marine heatwaves have caused widespread bleaching, and killed millions of corals. Because of this, a global search is underway for reefs that can withstand the heat stress, survive future warming, and act as sources of heat-tolerant coral larvae to replenish affected areas both naturally and through restoration. Now, scientists studying reefs in Palau, an archipelago in th...

Target to protect 30% of nature on Earth by 2030 A United Nations summit approved on Monday a landmark global deal to protect nature and direct billions of dollars toward conservation but objections from key African nations, home to large tracts of tropical rainforest, held up its final passage. The Kunming-Montreal Global Biodiversity Framework, reflecting the joint leadership of China and Canada, is the culmination of four years of work toward creating an agreement to guide global conservation efforts through 2030. There was widespread support for the final text put forward after two weeks of UN biodiversity negotiations to agree this decade’s targets for protecting nature, which included protecting 30% of the planet for nature by the end of the decade, reforming $500bn (£410bn...

Scientists freeze Great Barrier Reef coral in world-first trial

Scientists working on Australia's Great Barrier Reef have successfully trialled a new method for freezing and storing coral larvae they say could eventually help rewild reefs threatened by climate change. Scientists are scrambling to protect coral reefs as rising ocean temperatures destabilise delicate ecosystems. The Great Barrier Reef has suffered four bleaching events in the last seven years including the first ever bleach during a La Nina phenomenon, which typically brings cooler temperatures.

Glacier melting linked to shifting westerlies and likely to accelerate

The combination of global atmospheric warming and westerly winds shifting toward the poles will likely speed up the recession of mountain glaciers in both hemispheres, according to a UMaine study. Mountain glaciers freeze and gain mass when the climate cools, and melt and lose mass when the climate warms. The extent to which the fluctuations in mountain glaciers are reflective of local, regional and even hemispheric climate variations, however, is less clear, which has made it more difficult for scientists to use glacial data to interpret past climate dynamics and make predictions for the future. A team of researchers from the University of Maine conducted a National Science Foundation-funded study evaluating how atmospheric conditions are reflected in the mass fluctuations of m...
