Loss of Antarctic ice killed thousands of emperor penguin

August 25, 2023894 Views

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 frozen Antarctica is being walloped by climate extremes

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

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.

World’s biggest permafrost crater in Russia’s Far East thaws as planet warms

Stunning drone footage has revealed details of the Batagaika crater, a one kilometre long gash in Russia's Far East that forms the world's biggest permafrost crater. In the video two explorers clamber across uneven terrain at the base of the depression, marked by irregular surfaces and small hummocks, which began to form after the surrounding forest was cleared in the 1960s and the permafrost underground began to melt, causing the land to sink.

Antarctic ice levels undergo ‘massive decrease’, data shows

Antarctic sea ice levels reached record lows last month, the World Meteorological Organization (WMO) said on Monday, a development climate change experts described as worrisome. WMO said that Antarctic sea ice levels last month - the hottest June ever recorded -- were at their lowest since satellite observations began, at 17% below average. The Thwaites Glacier in Antarctica is seen in this undated NASA image. REUTERS/NASA/Handout via Reuters "We're used to seeing these big reductions in sea ice in the Arctic, but not in the Antarctic. This is a massive decrease," Michael Sparrow, Chief of World Climate Research Programme, told reporters in Geneva. Global sea surface temperatures were at record high for the time of the year in May and June, according to WMO, which warned that ...

Earth keeps breaking temperature records due to global warming On Monday, the global average temperature was the highest it’s ever been. It was even hotter on Tuesday. June was hottest June on record globally Global temperatures have smashed through records this week, underscoring the dangers of ever-increasing greenhouse gas emissions generated from burning fossil fuels. The average worldwide temperature reached 17C (63F) on Monday, just above the previous record of 16.9C in August 2016, according to data from the National Centers for Environmental Prediction. The threshold only lasted a day. On Tuesday, July 4, 2023, the average temperature hit 17.2C. This past June was also the hottest June globally on record in terms of sea and air temperatures, according to a statement by ...

Temperatures are expected to soar across large parts of the world after the El Nino weather pattern emerged in the tropical Pacific for the first time in seven years, the World Meteorological Organization said on Tuesday. El Nino, a warming of water surface temperatures in the eastern and central Pacific Ocean, is linked to extreme weather conditions from tropical cyclones to heavy rainfall to severe droughts. The world's hottest year on record, 2016, coincided with a strong El Nino - though experts says climate change has fuelled extreme temperatures even in years without the phenomenon.

Climate change fuels weather extremes in 2023 The target of keeping long-term global warming within 1.5 degrees Celsius (2.7 Fahrenheit) is moving out of reach, climate experts say, with nations failing to set more ambitious goals despite months of record-breaking heat on land and sea. As envoys gathered in Bonn in early June to prepare for this year's annual climate talks in November, average global surface air temperatures were more than 1.5C above pre-industrial levels for several days, the EU-funded Copernicus Climate Change Service (C3S) said.
