Europe experienced second-warmest winter on record

March 9, 20231069 Views

Europe is emerging from its second-warmest winter on record, European Union scientists said on Wednesday, as climate change continues to intensify. The average temperature in Europe from December to February was 1.4 degrees Celsius above the 1991-2020 average for the Boreal winter season, according to data published by the EU's Copernicus Climate Change Service (C3S).

Europe experienced a severe winter heatwave in late December and early January, when record-high winter temperatures hit count...

Human-wildlife conflicts rising worldwide with climate change

Research on the impacts of climate change often considers its effects on people separately from impacts on ecosystems. But a new study is showing just how intertwined we are with our environment by linking our warming world to a global rise in conflicts between humans and wildlife. The research, led by scientists at the University of Washington’s Center for Ecosystem Sentinels and published Feb. 27 in Nature Climate Change, reveals that a warming world is increasing human-wildlife conflicts. “We found evidence of conflicts between people and wildlife exacerbated by climate change on six continents, in five different oceans, in terrestrial systems, in marine systems, in freshwater systems – involving mammals, reptiles, birds, fish and even invertebrates,” said lead author Briana Abra...

Warm Canadian winter threatens Algonquin ice-fishing traditions

Most winters, at least once a week, Mike Diabo will snowmobile to the shores of one of his local lakes in southern Quebec, carry his fishing gear across the frozen surface, and drill down through the ice to reveal the dark water beneath. There he'll fish for northern pike, bass, trout, and whitefish to supplement his family's diet, continuing the traditions of his Anishinabe ancestors, part of the Algonquin First Nation of eastern Canada. But this year ice-fishing season started late, delayed by a warm winter and fluctuating temperatures that left the ice on Bitobi and Cedar Lakes - his two favourite haunts - slushy and dangerously thin until a cold snap finally arrived in early February. This winter is on track to be among the five warmest in southern Quebec since records began ...

Chilean wildfires destroy hundreds of homes, endanger world's smallest deer As his parents fought wildfires threatening their home in southern Chile, 13-year-old Lucas Cespedes decided to take action, ferrying firefighters across the local river in a small yellow rowing boat to help them put out the flames. The Andean country is battling some of the worst wildfires in years that have claimed 24 lives and burned through over 340,000 hectares (840,158 acres), affecting more than 5,400 people, destroying over a thousand homes and burning up the habitats of vulnerable woodland animals. Lucas Cespedes, 13, rows his boat during an interview with Reuters, close to his house on the shores of the river Futa, on the outskirts of Valdivia, Chile February 9, 2023.

Record low sea ice cover in the Antarctic

Sea ice extent in the Southern Ocean now the lowest since the beginning of satellite observation forty years ago There is currently less sea ice in the Antarctic than at any time in the forty years since the beginning of satellite observation: in early February 2023, only 2.20 million square kilometres of the Southern Ocean were covered with sea ice. Researchers from the Alfred Wegener Institute and the University of Bremen analyse the situation for the Sea Ice Portal. January 2023 had already set a new record for its monthly mean extent (3.22 million square kilometres), even though the melting phase in the Southern Hemisphere continues until the end of February. The current expedition team on board RV Polarstern has just reported virtually ice-free conditions in its current research...

Moving species emerges as last resort as climate warms

In a desperate effort to save a seabird species in Hawaii from rising ocean waters, scientists are moving chicks to a new island hundreds of miles away. Moving species to save them — once considered taboo — is quickly gaining traction as climate change upends habitats. Similar relocations are being suggested for birds, lizards, butterflies and even flowers. Concerns persist that the novel practice could cause unintended harm the same way invasive plants and animals have wreaked havoc on native species.

Climate change likely to uproot more Amazon trees

New study connecting extreme thunderstorms and tree deaths suggests the tropics will see more major blowdown events in a warming world Tropical forests are crucial for sucking up carbon dioxide from the atmosphere. But they’re also subject to intense storms that can cause “windthrow” – the uprooting or breaking of trees. These downed trees decompose, potentially turning a forest from a carbon sink into a carbon source. Members of NGEE-Tropics visit what they named “Blowdown Gardens,” an area that experienced windthrow near one of their field sites in the Amazon. Photo Credit: Jeff Chambers/Berkeley Lab A new study finds that more extreme thunderstorms from climate change will likely cause a greater number of large windthrow events in the Amazon rainforest. This is one of the fe...

Vulnerability, resilience, and hopeful potential in world’s tallest trees

Redwoods and Climate Change Scientists from Cal Poly Humboldt conducted a rangewide analysis of coast redwood (Sequoia sempervirens) to examine growth trends and understand how these trees are responding to recent environmental changes. They found that redwoods have varying sensitivity to drought, and that rising temperatures may affect tree performance in unexpected ways—results that are both concerning and hopeful. Coastal fog helps alleviate drought stress. Nighttime fog, in particular, is one of the best predictors of redwood growth efficiency. Phot Credit: (Courtesy of Steve Sillett) The study, published in Forest Ecology and Management, was led by Cal Poly Humboldt Forestry Professor Stephen C. Sillett, the Kenneth L. Fisher Chair in Redwood Forest Ecology. Sillett’s team w...

Uneven wetting affecting Tibetan Plateau

December 27, 2022806 Views

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...

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.
