European climate agency says this will likely be the hottest year on record — again

November 9, 2024124 Views

For the second year in a row, Earth will almost certainly be the hottest it’s ever been. And for the first time, the globe this year reached more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming compared to the pre-industrial average, the European climate agency Copernicus said Thursday. “It’s this relentless nature of the warming that I think is worrying,” said Carlo Buontempo, director of Copernicus. Buontempo said the data clearly shows the planet would not see such a long sequence of record-breaking temperatures without the constant increase of greenhouse gases in the atmosphere driving global warming. He cited other factors that contribute to exceptionally warm years like last year and this one. They include El Nino — the temporary warming of parts of the Pac...

Mount Fuji is without its iconic snowcap in November for the first time in 130 years

Japan’s iconic Mount Fuji, known for its snowcap forming around this time of the year, is still snowless in November for the first time in 130 years, presumably because of the unusually warm temperatures in the past few weeks. The lack of snow on Mt. Fuji, a UNESCO World Heritage site, as of Tuesday breaks the previous record set on Oct. 26, 2016, meteorological officials said. Usually, the 3,776-meter- (nearly 12,300-foot-) high mountain has sprinkles of snow falling on its summit starting Oct. 2, about a month after the summertime hiking season there ends. Last year, snow fell on the mountain on Oct. 5, according to the Japan Meteorological Agency, or JMA. The snowless Mt. Fuji has captured attention on social media. People posted photos showing the bare mountain, some expr...

Is climate change lighting a fuse under Iceland’s volcanoes?

Scientists are racing to find out whether the rapid retreat of glaciers could drive a surge in eruptions as magma builds under the island nation — and if so, whether the same might occur at ice-covered volcanoes around the world, putting many lives at risk. Toxic sulphurous gas, carrying the telltale reek of rotten eggs, wafted through vents in the steep walls of Iceland’s Viti crater, while carbon dioxide bubbled to the surface of the milky blue crater lake. Veils of steam wreathed the landscape of loose rock in eerie half-light. Through this forbidding terrain – “Viti” is derived from the Icelandic for “hell” – Michelle Parks, a volcanologist with the Icelandic Meteorological Office, picked her way toward the water’s edge one day last August. With a monitor strapped...

COP16: From forests to oceans, nature in a dire state

Global destruction of nature has reached unprecedented extremes. As the United Nations two-week COP16 biodiversity summit kicks off on Monday in Cali, Colombia, here is what you need to know about nature's rapid decline - and its importance to the global economy. ANIMALS AND PLANTS Plants and animals play significant parts in keeping nature humming, from cycling nutrients throughout an ecosystem to aerating soils and engineering rivers. Without plants and animals, the world would not be habitable for humans. However, more than a quarter of the world's known species, or a total of about 45,300 species, are now threatened with extinction, according to the International Union for Conservation of Nature and Natural Resources (IUCN).

Vegetation is taking over snow in Antarctica

Lush landscape is spreading at an alarming rate in a place where temperatures are soaring A fast-warming region of Antarctica is getting greener with shocking speed. Satellite imagery of the region reveals that the area covered by plants increased by almost 14 times over 35 years — a trend that will spur rapid change of Antarctic ecosystems. “It's the beginning of dramatic transformation,” says Olly Bartlett, a remote-sensing specialist at the University of Hertfordshire in Hatfield, UK, and an author of the study, published recently in Nature Geoscience, that reports these results. From white to green Bartlett and his colleagues analysed images taken between 1986 and 2021 of the Antarctic Peninsula — a part of the continent that juts north towards the tip of South America.

Swiss glacier melt exceeds average in 2024 after hot summer

Swiss glaciers melted at an above-average rate in 2024 as a blistering hot summer thawed through abundant snowfall, monitoring body GLAMOS said on Tuesday. Earlier this year, glaciologists had celebrated heavy winter and spring snow dumps in the Alps, hoping this would signal a halt to years of hefty declines or even a reversal of losses.

Overall, GLAMOS said Swiss glaciers lost 2.5% of their volume this year which was abo...

Polar bears are now half the number of 40 years ago

In the gateway to the Arctic, fat, ice and polar bears are crucial. All three are in trouble Searching for polar bears where the Churchill River dumps into Canada’s massive Hudson Bay, biologist Geoff York scans a region that’s on a low fat, low ice diet because of climate change. And it’s getting lower on polar bears. A polar bear cub walks along rocks toward its mother, Wednesday, Aug. 7, 2024, near Churchill, Manitoba. (AP Photo/Joshua A. Bickel) There are now about 600 polar bears in the Western Hudson Bay, one of the most threatened of the 20 populations of the white beasts. That’s about half the number of 40 years ago, says York, senior director of research and policy at Polar Bears International. His latest study, with a team of scientists from various fields, shows tha...

As warming threatens polar bear tourism, a Canadian town adapts and thrives

Change has broken, remade and continues to reshape this remote town where tundra meets forest on the shore of Hudson Bay. The economic base collapsed when the military left town. Rail service and cargo ships — the lifeblood of supplies for a town not connected to the rest of the world by roads — blinked out. The weather is warming, signature animals are dwindling and even the ground is shifting. Through it all, Churchill has adapted. The town turned to tourism, luring people eager to see its plentiful polar bears. Leaders figured out ways to revitalize its port and railway. As climate change has edged into the picture, they’ve begun designing more flexible buildings and seeking to entice more varied visitors if, as scientists fear, shrinking sea ice crashes the bear population. T...

South America's Paraguay River, a key thoroughfare for grains, has hit a record low in Paraguay's capital Asuncion, with water levels depleted by a severe drought upriver in Brazil that has hindered navigation along waterways in the Amazon. A powerful drought in the Amazon rainforest led on Monday to the lowest water levels on the Paraguay River in more than a century, disrupting commerce on the major waterway, creating hazards for local transport and offering a grim warning for other parts of the world.

This year could be the warmest humanity has ever measured

Summer 2024 sweltered to Earth’s hottest on record, making it even more likely that this year will end up as the warmest humanity has measured, European climate service Copernicus reported Friday. And if this sounds familiar, that’s because the records the globe shattered were set just last year as human-caused climate change, with a temporary boost from an El Nino, keeps dialing up temperatures and extreme weather, scientists said. The northern meteorological summer — June, July and August — averaged 16.8 degrees Celsius (62.24 degrees Fahrenheit), according to Copernicus. That’s 0.03 degrees Celsius (0.05 degrees Fahrenheit) warmer than the old record in 2023. Copernicus records go back to 1940, but American, British and Japanese records, which start in the mid-19th century, show ...
