Swiss glaciers suffer rapid ice loss following weak winter snowfall
Glacier Loss Day (GLD) is marked every year by researchers in Switzerland. It represents the point when a glacier has melted away all the snow and ice it gained during the winter.
Depending on the glacier, it arrived as early as late June or early July this year.
'In some regions in north-eastern Switzerland, we've never had such a small amount of snow on the glaciers at the end of winter', researcher Andreas Bauder of ETH Zurich said of the mountain conditions going into the summer months. 'As long as there is snow on the ground, the ice won't melt. But this year, the snow melt began at the end of May and continued rapidly throughout June and into July', he said.
In Switzerland, snow and ice cover are measured in detail every spring and fall on about 20 of the country's roughly 1,400 glaciers. Between 10 and 15 of those are also monitored during the summer. These observations are used to determine the Glacier Loss Day.
Looking back to last year, the summer began with much larger snow reserves than this year, according to Bauder. Even so, glaciers still lost more mass in 2024 than they gained during the winter, leading them to shrink.
'In the past, Glacier Loss Day usually came at the end of August or early September-but we haven't seen that in the past 20 years', said Bauder. — dpa

Swiss glaciers suffer rapid ice loss following weak winter snowfall
GENEVA: Switzerland's glaciers are melting at an alarming pace this year, with scientists warning that the loss of ice cover began weeks earlier than usual due to a snow-poor winter.

World's richest 10% caused two thirds of global warming: study
The world's wealthiest 10 percent of individuals are responsible for two thirds of global warming since 1990, researchers said on Wednesday. How the rich consume and invest has substantially increased the risk of deadly heatwaves and drought, they reported in the first study to quantify the impact of concentrated private wealth on extreme climate events. "We link the carbon footprints of the wealthiest individuals directly to real-world climate impacts," lead author Sarah Schoengart, a scientist at ETH Zurich, told AFP. "It's a shift from carbon accounting toward climate accountability." Compared to the global average, for example, the richest one percent contributed 26 times more to once-a-century heatwaves, and 17 times more to droughts in the Amazon, according to the findings, published in Nature Climate Change. Emissions from the wealthiest 10 percent in China and the United States -- which together account for nearly half of global carbon pollution -- each led to a two-to-threefold rise in heat extremes. Burning fossil fuels and deforestation have heated Earth's average surface by 1.3 degrees Celsius, mostly during the last 30 years. Schoengart and colleagues combined economic data and climate simulations to trace emissions from different global income groups and assess their impact on specific types of climate-enhance extreme weather. The researchers also emphasised the role of emissions embedded in financial investment rather than just lifestyle and personal consumption. "Climate action that doesn't address the outsized responsibilities of the wealthiest members of society risk missing one of the most powerful levers we have to reduce future harm," said senior author Carl-Friedrich Schleussner, head of the Integrated Climate Impacts Research Group at the International Institute for Applied Systems Analysis near Vienna. - Billionaires tax - Owners of capital, he noted, could be held accountable for climate impacts through progressive taxes on wealth and carbon-intensive investments. Earlier research has shown that taxing asset-related emissions is more equitable than broad carbon taxes, which tend to burden those on lower incomes. Recent initiatives to increase taxes on the super-rich and multinationals have mostly stalled, especially since Donald Trump regained the White House. Last year, Brazil -- as host of the G20 -- pushed for a two-percent tax on the net worth of individuals with more than $1 billion in assets. Although G20 leaders agreed to "engage cooperatively to ensure that ultra-high-net-worth individuals are effectively taxed," there has been no follow-up to date. In 2021, nearly 140 countries agreed on work toward a global corporate tax for multinational companies, with nearly half endorsing a minimum rate of 15 percent, but those talks have stalled as well. Almost a third of the world's billionaires are from the United States -- more than China, India and Germany combined, according to Forbes magazine. According to anti-poverty NGO Oxfam, the richest 1 percent have accumulated $42 trillion in new wealth over the past decade. It says the richest one percent have more wealth than the lowest 95 percent combined. —AFP

Scientists record first evidence of shark making noise
Researchers have recorded what they believe to be the first evidence of sharks making noise, according to newly published research. The scientists recorded New Zealand rig sharks (Musteluslenticulatus), small sharks found in coastal waters all around the country, producing clicks when handled underwater, in what they believe is the "first documented case of active sound production by a shark." Ten juvenile rig sharks - five female and five male - were used for the study over the 11-month study. The sounds were recorded in an experimental plastic tank set up to record the sounds. The researchers, led by Carolin Nieder from the Woods Hole Oceanographic Institution in the US, found that on average "the sharks produced significantly more clicks" in the first 10 seconds of handling compared to the following 10 seconds. They believe that the forceful snapping together of the rig shark's flattened teeth is the likely source of the sound. They base the hypothesis on the rig shark's plated teeth morphology as well as the type of noise produced, specifically its short duration (48 milliseconds) and high peak frequencies (2.4-18.5 kHz),but said that more research is needed to confirm this. The biologists said that the purpose of the clicking sound "remains uncertain," but it may be produced "in response to disturbance or distress." Further behavioural research will be required to investigate this. The research was published in the journal Royal Society Open Science. —dpa
