South America’s rivers hit record lows as Brazil drought impact spreads

September 10, 2024183 Views

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 ...

Scientists in Chile question if Antarctica has hit a point of no return

Nearly 1,500 academics, researchers and scientists specializing in Antarctica gathered in southern Chile for the 11th Scientific Committee on Antarctic Research conference this week to share the most cutting-edge research from the vast white continent. Nearly every aspect of science, from geology to biology and glaciology to arts, was covered but a major undercurrent ran through the conference. Antarctica is changing, faster than expected. Extreme weather events in the ice-covered continent were no longer hypothetical presentations, but first-hand accounts from researchers about heavy rainfall, intense heat waves and sudden Foehn (strong dry winds) events at research stations that led to mass melting, giant glacier break-offs and dangerous weather conditions with global implications...

The worldwide catastrophe of rising seas especially imperils Pacific paradises

Highlighting seas that are rising at an accelerating rate, especially in the far more vulnerable Pacific island nations, U.N. Secretary-General Antonio Guterres issued yet another climate SOS to the world. This time he said those initials stand for “save our seas.” The United Nations and the World Meteorological Organization Monday issued reports on worsening sea level rise, turbocharged by a warming Earth and melting ice sheets and glaciers. They highlight how the Southwestern Pacific is not only hurt by the rising oceans, but by other climate change effects of ocean acidification and marine heat waves. Guterres toured Samoa and Tonga and made his climate plea from Tonga’s capital on Tuesday at a meeting of the Pacific Islands Forum, whose member countries are among those most impe...

Drought-threatened Amazon dolphins studied for climate change impact

A team of biologists, vets and fishermen temporarily captured rare freshwater dolphins in the Amazon this week to study their health in hopes of avoiding a repeat of the deaths of hundreds of the mammals last year due to a severe drought. The dolphins, that are in danger of extinction, were brought ashore for blood tests and other examinations and returned to Lake Tefé in the Amazon basin as soon as the researchers had finished their work. Fishermen were careful not to injure an adult female dolphin during capture and kept her close to her young offspring to avoid stressing the animals. Field researchers from the Mamiraua Institute of Sustainable Development capture a rare Amazon river dolphin, also known as the pink river dolphin, during an expedition in Tefe, Amazonas state, Br...

Tahiti’s rahui tradition has helped revive ecosystems

During their days on Tahiti’s turquoise ocean some years ago, fishers noticed their catches — and the fish inside — were getting smaller. With fishing being a vital part of the ways of Polynesian life, local leader Dominique Tehei, 51, and his fellow community members knew they needed to find a way to restore the ecosystem. They decided there was a customary Polynesian practice that could help them do it: creating a rahui. The traditional conservation method of regulating human activity to help replenish and protect maritime ecosystems resources is being revived and showing results in Tahiti, including the area near the Paris Olympics surfing venue. While local communities and leaders acknowledge that rahui aren’t a one-stop solution to all environmental issues, they’re working with...

Hungary’s famed white wine under threat due to heatwave

Hungary's hottest July on record has forced some of the country's winemakers to start harvesting grapes in early August, up to a month earlier than usual. Climate change is having a severe impact on Hungary's acclaimed winemaking industry, as rising temperatures could make the country too hot for producing white wine, including the renowned Tokaji, scientists say.

Kerek, who was harvesting grapes with his family in early August by hand, attributes the early harv...

Hottest oceans in 400 years endanger Great Barrier Reef, scientists say

Water temperatures in and around Australia's Great Barrier Reef have risen to their warmest in 400 years over the past decade, placing the world's largest reef under threat, according to research published on Thursday. The reef, the world's largest living ecosystem, stretches for some 1,500 miles (2,400 km) off the coast of the northern state of Queensland. A group of scientists at universities across Australia drilled cores into the coral and, much like counting the rings on a tree, analysed the samples to measure summer ocean temperatures going back to 1618.

Recent glacier retreat across the Andes is unprecedented in the history of human civilization, according to a new study published in the Science journal on Thursday. The discovery shocked scientists, who initially planned to study the current state of glaciers and how they had varied throughout human civilization.

REUTERS/Ivan Alvarado "We thought this result was decades away," said Andrew Gorin, lead author of the study, who first believed the initial results were a fluke, but were confirmed by later samples. "It goes to show you that this is happening faster than even those of us that think about this the mos...

Galapagos Islands and many unique creatures are at risk from warming waters

Warm morning light reflects from the remains of a natural rock arch near Darwin Island, one of the most remote islands in the Galapagos. In clear, deep blue water, thousands of creatures — fish, hammerhead sharks, marine iguanas — move in search of food. The 2021 collapse of Darwin’s Arch, named for the famed British naturalist behind the theory of evolution, came from natural erosion. But its demise underscored the fragility of a far-flung archipelago that’s coming under increased pressure both from climate change and invasive species. A piece of the edge of Darwin’s Arch is visible in the ocean above Pacific creolefish off of Darwin Island, Ecuador in the Galapagos on Thursday, June 13, 2024.
