Whales, dolphins in American waters are losing food and habitat to climate change

October 8, 2023845 Views

Whales, dolphins and seals living in U.S. waters face major threats from warming ocean temperatures, rising sea levels and decreasing sea ice volumes associated with climate change, according to a first-of-its-kind assessment. Researchers with the National Oceanic and Atmospheric Administration examined more than 100 stocks of American marine mammal species and found more than 70% of those stocks are vulnerable to threats, such as loss of habitat and food, due to the consequences of warming waters. The impacts also include loss of dissolved oxygen and changes to ocean chemistry. FILE PHOTO: A harbor seal surfaces in Casco Bay on July 30, 2020, off Portland, Maine. (AP Photo/Robert F.

A Swiss Academy of Sciences panel is reporting a dramatic acceleration of glacier melt in the Alpine country, which has lost 10% of its ice volume in just two years after high summer heat and low snow volumes in winter. Switzerland — home to the most glaciers of any country in Europe — has seen 4% of its total glacier volume disappear in 2023, the second-biggest decline in a single year on top of a 6% drop in 2022, the biggest thaw since measurements began, the academy’s commission for cryosphere observation said.

Fisherman Vancho Vasilevski's boat frequently runs aground when he sails on Lake Prespa, one of Europe's oldest lakes and home to more than 2,000 species of fish, birds, mammals and plants, in a sign of how much water the lake is losing. "In the last two, three months the water has dropped 36 centimetres and in last days probably another two or three centimetres," said Vasilevski, who is in his late 60s.

There is no rain, no winter, no snow, no rivers. Only one river is coming into the lake... This is a disaster, a natural disaster." The decline has continued over decades - the water at Lake Prespa...

Summer 2023 was hottest on record, scientists say

The summer of 2023 was the hottest on record, according to data from the European Union Climate Change Service released on Wednesday. The three-month period from June through August surpassed previous records by a large margin, with an average temperature of 16.8 degrees Celsius (62.2F) - 0.66C above average. Last month was the also the hottest August on record globally, the third straight month in a row to set such a record following the hottest ever June and July, the EU said on Wednesday.

Recent heat wave threatens severe glacier melt again in Switzerland

September 1, 2023822 Views

A top glacier watcher has warned that a warm early summer combined with a heat wave last week may have caused severe glacier melt in Switzerland, threatening to make 2023 its second-worst year for ice loss after a record thaw last year. Matthias Huss of the GLAMOS glacier monitoring center said full data won’t be in until late September and a precipitous drop in temperatures and high-altitude snowfall in recent days could help stem any more damage. But early signs based on readings from five sites and modeling results across Switzerland suggest considerable damage may already be done. “We can definitely say that we had very high melting in Switzerland and in Europe in general because the temperatures, they were extremely high for a long time — a more than one week heat wave,”...

Loss of Antarctic ice killed thousands of emperor penguin

The loss of ice in one region of Antarctica last year likely resulted in none of the emperor penguin chicks surviving in four colonies, researchers reported Thursday. Emperor penguins hatch their eggs and raise their chicks on the ice that forms around the continent each Antarctic winter and melts in the summer months. Researchers used satellite imagery to look at breeding colonies in a region near Antarctica’s Bellingshausen Sea. The images showed no ice was left there in December during the Southern Hemisphere’s summer, as had occurred in 2021.

Changing climate pushes migrating birds from parched Tunisian wetlands

Tunisia's lakes and coastal lagoons are parched and overheating, endangering a delicate ecosystem and disrupting the vast flocks of migrating birds that use the wetlands as a way station between Africa and Europe. Ariana lagoon just outside the capital Tunis has been left a cracked expanse of dry mud, its small islands where birds usually nest now surrounded by sand and bereft of life after months of drought and a ferocious heatwave.

Even in Antarctica — one of the most remote and desolate places on Earth — scientists say they are finding shattered temperature records and an increase in the size and number of wacky weather events. The southernmost continent is not isolated from the extreme weather associated with human-caused climate change, according to a new paper in Frontiers in Environmental Science that tries to make a coherent picture of a place that has been a climate change oddball. Its western end and especially its peninsula have seen dramatic ice sheet melt that threatens massive sea level rises over the next few centuries, while the eastern side has at times gained ice. One western glacier is melting so fast that scientists have nicknamed it the Doomsday Glacier and there’s an international effort tryin...

Crammed with tourists, Alaska wonders what happens as its magnificent glacier recedes

August 6, 2023878 Views

Thousands of tourists spill onto a boardwalk in Alaska’s capital city every day from cruise ships towering over downtown. Vendors hawk shoreside trips and rows of buses stand ready to whisk visitors away, with many headed for the area’s crown jewel: the Mendenhall Glacier. A craggy expanse of gray, white and blue, the glacier gets swarmed by sightseeing helicopters and attracts visitors by kayak, canoe and foot. So many come to see the glacier and Juneau’s other wonders that the city’s immediate concern is how to manage them all as a record number are expected this year. Some residents flee to quieter places during the summer, and a deal between the city and cruise industry will limit how many ships arrive next year. But climate change is melting the Mendenhall Glacier. It is re...

Largest lake in South America is drying up

Unusual heat wave turns winter upside down in southern hemisphere The parched shoreline and shrinking depths of Lake Titicaca are prompting growing alarm that an ago-old way of life around South America's largest lake is slipping away as a brutal heat wave wreaks havoc on the southern hemisphere's winter. Like many places suffering deadly consequences of climate change, the sprawling freshwater lake nestled in the Andes mountains on Bolivia's border with Peru now features a water level approaching an all-time low.
