Early jacaranda bloom sparks debate about climate change

February 25, 2024571 Views

Every spring, the streets of Mexico's capital are painted purple with the flowering of thousands of jacaranda trees. Their spectacular colors not only attract the eyes of residents and tourists, but also birds, bees and butterflies that find food and shelter in them. But this year something changed. Some jacarandas began blooming in early January, when they normally awaken in spring. The early onset bloom has set off alarm bells among residents and scientists in Mexico City, where the trees have become an iconic, photogenic mainstay of city streets. Local scientists have begun investigating how widespread the early-bloom phenomenon is, but they point to climate change as the first culprit. People walk near a jacaranda tree at Plaza Cibeles in Mexico City, Mexico. February 22, ...

Climate change clouds future of winter sports

Pietro Casartelli always dreamed of becoming a professional athlete, but the alpine skier, 18, says climate change is making his goals harder and much more expensive to achieve. Last year, as his usual high altitude summer ski slopes were melted by record-high temperatures, he had planned to join a training camp in Chile. But the trip was cancelled as too few would-be participants could afford the fees. Warming weather systems and a shorter season are threatening winter sports and testing the resolve of professionals and amateurs alike, across Europe.

# First 12-month period above 1.5C threshold # World just had hottest January on record # Climate change, El Nino push up temperatures # Scientists urge rapid action to cut emissions The world just experienced its warmest January on record, marking the first 12-month period in which temperatures averaged more than 1.5C (2.7F) above pre-industrial times, the European Union's climate change monitoring service said on Thursday. Already 2023 was the planet's hottest year in global records going back to 1850, as human-caused climate change and El Nino, the weather pattern that warms the surface waters in the eastern Pacific Ocean, pushed temperatures higher.

Swiss ski spot left snowless, deserted by mild January

The once-popular ski runs of Dent-de-Vaulion in the Swiss Jura Mountains are now deserted as unusually mild weather has driven away winter sport enthusiasts and forced ski resorts to close across the country. Abandoned pole rods of the ski lift sway in the wind. Crusty snow dots stretches of yellowed grass. Lift pylons stand alone in rocky terrain where cheerful crowds once puffed steam in frigid temperatures. A view shows the closed Dent-de-Vaulion ski lift amid lack of snow at altitudes below 1500 m due to high winter temperatures induced by climate change, in Vaulion, Switzerland, February 2, 2024.

Glacier melting destroys important climate data archive

As part of the Ice Memory initiative, PSI researchers, with colleagues from the University of Fribourg and Ca’ Foscari University of Venice as well as the Institute of Polar Sciences of the Italian National Research Council (CNR), analysed ice cores drilled in 2018 and 2020 from the Corbassière glacier at Grand Combin in the canton of Valais. A comparison of the two sets of ice cores published in Nature Geoscience shows: Global warming has made at least this glacier unusable as a climate archive. Reliable information about the past climate and air pollution can no longer be obtained from the Corbassière glacier in the Grand Combin massif, because alpine glacier melting is progressing more rapidly than previously assumed. This sobering conclusion was reached by researchers led by Margit...

Alpine glaciers to shrink by more than a quarter by 2050, whatever happens

Even if global warming were to stop completely, the volume of ice in the European Alps would fall by 34% by 2050. If the trend observed over the last 20 years continues at the same rate, however, almost half the volume of ice will be lost as has been demonstrated by scientists from the University of Lausanne (UNIL, Switzerland) in a new international study. By 2050, i.e. in 26 years' time, we will have lost at least 34% of the volume of ice in the European Alps, even if global warming were to stop completely and immediately. This is the prediction of a new computer model developed by scientists from the Faculty of Geosciences and Environment at the University of Lausanne (UNIL), in collaboration with the University of Grenoble, ETHZ and the University of Zurich. In this scenario, devel...

Scientists reveal how Greenland Ice Sheet has shrunk over past four decades

The Greenland Ice Sheet lost 5,091 sq km (1930 sq miles) of area between 1985 and 2022, according to a study in the journal Nature published on Wednesday, the first full ice-sheet wide estimate of area loss on that scale. This shrinkage reflected the 1,034 gigatonnes (1.034 trillion kg.) of ice that have been lost as glaciers retreated, shedding ice through "calving" - when ice chunks break off from a glacier - at their terminating ends. FILE PHOTO: The edge of the ice sheet is pictured south of Ilulissat, Greenland, September 17, 2021. REUTERS/Hannibal Hanschke The study is also the first to fully estimate how much ice Greenland has lost due specifically to glacial retreat. It suggests previous estimates of changes to the Greenland Ice Sheet's mass balance - how much snow and ic...

2023 was world’s hottest year on record

Scientists knew it would make history — but not by this much Last year was the planet's hottest on record by a substantial margin and likely the world's warmest in the last 100,000 years, the European Union's Copernicus Climate Change Service (C3S) said on Tuesday. Scientists had widely expected the milestone, after climate records were repeatedly broken. Since June, every month has been the world's hottest on record compared with the corresponding month in previous years. "This has been a very exceptional year, climate-wise... in a league of its own, even when compared to other very warm years," C3S Director Carlo Buontempo said.

Heat of climate change in a sacred forest and valley

Majestic cedar trees towered over dozens of Lebanese Christians gathered outside a small mid-19th century chapel hidden in a mountain forest to celebrate the Feast of the Transfiguration, the miracle where Jesus Christ, on a mountaintop, shined with light before his disciples. The sunset’s yellow light coming through the cedar branches bathed the leader of Lebanon’s Maronite Church, Patriarch Beshara al-Rai, as he stood at a wooden podium and delivered a sermon. Then the gathering sang hymns in Arabic and the Aramaic language. For Lebanon’s Christians, the cedars are sacred, these tough evergreen trees that survive the mountain’s harsh snowy winters. They point out with pride that Lebanon’s cedars are mentioned 103 times in the Bible. The trees are a symbol of Lebanon, pictured at t...

November is the sixth straight month to set a heat record The last half year has truly been shocking, scientists are running out of adjectives to describe this European Union scientists said on Wednesday that 2023 would be the warmest year on record, as global mean temperature for the first 11 months of the year hit the highest level on record, 1.46 degrees Celsius (2.63 degrees Fahrenheit) above the 1850-1900 average. For the sixth month in a row, Earth set a new monthly record for heat, and also added the hottest autumn to the litany of record-breaking heat this year, the European climate agency calculated. And with only one month left, 2023 is on the way to smashing the record for hottest year. FILE PHOTO: Manuel Flores walks on a dry area that shows the drop in the level...
