Researchers recently found an "undiscovered landscape" beneath Antarctica's ice. But between 14 million and 34 million years ago, an ice sheet crept across the continent. It locked some of the lush landscape beneath over a mile of ice, per NBC News. This helped the researchers determine the height of peaks and depths of valleys that lay hidden beneath the ice. A rewarming AntarcticaIt's crucial to understand how warming temperatures will impact Antarctica's ice.

The Labor Day tragedy in 2019 spurred changes to maritime regulations, congressional reform and civil lawsuits. At the time of the fire, no owner, operator or charterer had been cited or fined for failure to post a roving patrol since 1991, Coast Guard records showed. The NTSB faulted the Coast Guard for not enforcing that requirement and recommended it develop a program to ensure boats with overnight passengers actually have the watchman. The Coast Guard has since enacted new regulations regarding fire detection systems, extinguishers, escape routes and other safety measures as mandated by Congress. Victims' families have sued the Coast Guard in one of several ongoing civil suits.

☆ Ancient landscape formed by rivers revealed deep under Antarctic ice

Researchers said on Tuesday they have detected buried under the continent's ice sheet a vast ancient landscape, replete with valleys and ridges, apparently shaped by rivers before being engulfed by glaciation long ago. Ancient palm tree pollen has been discovered from Antarctica, not far around the coast from our study site," Jamieson added. Some previous studies similarly have revealed ancient landscapes beneath Antarctica's ice including mountains and highlands, though the landscape discovered in the new study was the first of its type. Right before 34 million years ago, Antarctica's landscape and flora likely resembled today's cold temperate rainforests of Tasmania, New Zealand and South America's Patagonia region, Ross added. When that ice growth occurred, the conditions between the base of the ice and the landscape changed to become very cold - and in this way it was no longer able to erode our landscape.

☆ Climate change: Rapid melting of West Antarctica ice now 'unavoidable,' study finds
▼ + stars: | 2023-10-23 | by ( Rachel Ramirez | ) edition.cnn.com time to read: +5 min

CNN —Rapid melting of West Antarctica’s ice shelves may now be unavoidable as human-caused global warming accelerates, with potentially devastating implications for sea level rise around the world, new research has found. Even if the world meets ambitious targets to limit global heating, West Antarctica will experience substantial ocean warming and ice shelf melting, according to the new study published Monday in the journal Nature Climate Change. They act like buttresses, helping hold ice back on the land, slowing its flow into the sea and providing an important defense against sea level rise. While there has been growing evidence ice loss in West Antarctica may be irreversible, there has been uncertainty about how much can be prevented through climate policies. “The thing that’s depressing is the committed nature of sea level rise, particularly for the next century,” Scambos told CNN.

No matter how much the world cuts back on carbon emissions, a key and sizable chunk of Antarctica is essentially doomed to an “unavoidable” melt, a new study found. Researchers used computer simulations to calculate future melting of protective ice shelves jutting over Antarctica’s Amundsen Sea in western Antarctica. How much melting can still be prevented by reducing emissions?” said study lead author Kaitlin Naughten, an oceanographer at the British Antarctic Survey. In each case, ocean warming was just too much for this section of the ice sheet to survive, the study found. That part of Antarctica “is doomed,” said University of California Irvine ice scientist Eric Rignot, who wasn’t part of the study.

The study, published in the journal Nature Climate Change on Monday, found no matter the degree of warming this century, the melting of the West Antarctic Ice Sheet will speed up as warmer water in the Amundsen Sea erodes ice shelves bordering the ocean. These ice shelves buttress ice further inland, acting as a cork in a bottle that stops their flow into the ocean. The collapse of the West Antarctic Ice Sheet is one of nine global climate 'tipping points' scientists identified in 2009. If the ice sheet were to fully melt, average global sea levels would rise by more than a metre. Antarctic Sea ice saw its lowest maximum extent on record this winter.

Tiny but bountiful, Antarctic krill make up one of the planet’s largest biomasses, nourishing everything from fish to marine mammals and seabirds. At Steinberg’s lab, researchers are examining how warming oceans — Antarctic krill need water colder than 4 degrees Celsius (39 Fahrenheit) to survive — are altering krill’s life cycle. However, a leading marine biologist the industry once relied on to burnish its environmental credentials has since denounced krill fishing. She accepted with the hope that she could help mitigate the effects of krill fishing on the Antarctic ecosystem. Today, she believes that krill fishing should be banned.

AdvertisementAdvertisementAntarctic ice shelves lost about 8.3 trillion tons of ice in the last quarter-century — enough to cover the contiguous US in 3 feet of water. All told, Antarctic ice shelves lost about 8.3 trillion tons (7.5 trillion metric tons) of ice in the 25-year period, the study found. The largest of the Larsen ice shelves, Larsen C, has lost 1.8 billion tons (1.7 trillion metric tons) of ice, about one-eighth of its mass. The shelf has lost 70% of its mass since 1997 — about 4.1 trillion tons (3.7 trillion metric tons) — into the Amundsen Sea. The ice shelves on the east were growing slower than the shelves losing ice to the west.

Antarctica was once a pristine preserve, but humans are ruining it. And this past winter, the frozen continent reached record-low sea ice levels. USGS"This region is nearing a threshold of rapid landscape change," researchers noted in 2017. Pauline Askin/ReutersAnd depending on the location, that ice melt could turn up some pretty nasty stuff. What's even more worrisome is that "human impacts are disproportionately concentrated on the most environmentally significant areas of Antarctica," the researchers noted.

A German startup hoping to help put an end to plastic pollution has just raised 36.6 million euro (around $38.9 million) in a mixture of equity and debt. Hamburg-based Traceless, founded in 2020, has developed a plant-based biomaterial using agricultural waste to replace plastics. The startup material uses the existing natural polymers that are in its raw material, which requires up to 80% less energy to process compared to conventional plastics, Lamp said. Traceless produces its material as small pellets to provide to product manufacturers, which then mould it to their needs. The startup hopes to have replaced 1 million tonnes of plastic by 2030.

They believe an ancient ocean floor may be wrapped around our planet's mysterious core. The research suggests that Earth's core could be encased in an ancient ocean floor that features giant mountains five times the size of Mount Everest. Scientists have found looking at data from earthquakes that there may be a layer of ancient ocean floor coating the Earth's core. For them, the answer was clear: the layer was likely bits of ancient ocean floor, gobbled up over the ages from the surface as tectonic plates stretched and squished together. Due to its composition, the ocean floor is a perfect candidate for this layer, Hansen said.
