Antarctic ice shelves: Searching for clues on climate change

Chile's Escudero base on King George Island acts as a research hub for a frozen expanse that extends to the South Pole, with more than 300 international scientists taking turns to brave the bitter Antarctic temperatures. The Chilean Antarctic Institute (INACH) has supported research into a biomolecule called "Antartina," derived from a plant native to the region, which has shown positive early results in diminishing colorectal, liver and gastric cancers in mice. This month a multinational team...

Search for Shackleton's Endurance called off after loss of submarine

Weddell Sea expedition team loses contact with autonomous vehicle under ice sheetThe search for Sir Ernest Shackleton’s lost ship, Endurance, has been called off after extreme weather trapped an underwater vehicle under a sheet of ice.Explorers working on the Weddell Sea Expedition had hoped to find the Antarctic explorer’s vessel, which was crushed by ice and sank in 1915 during his ultimately unsuccessful attempt at a land crossing of the continent. But severe weather closed in and the sea ice...

When Warren Washington created the first climate model, he had no idea how necessary it was. He just won the 'Nobel Prize for the environment.'

Warren Washington, who's 89 years old, has been awarded the 2019 Tyler Prize for Environmental Achievement — an award sometimes described as the "Nobel Prize for the environment." The prize honors Washington's pioneering work modeling Earth's climate. Washington's climate models have been integral to the scientific community and general public because they've improved our ability study weather patterns and make predictions about the impacts of climate change. Washington is ...

Climate change to change the color of the oceans over the next 80 years

The color of the oceans is about to undergo some major changes. As a result of ongoing climate change, scientists are predicting that the color of the oceans will slowly become bluer over the next 80 years. The color difference is directly connected to microbial phytoplankton, which absorb sunlight near the surface of the ocean. As the acidity and temperature of the oceans rise, the number of phytoplankton is expected to decrease in certain regions. Once the phytoplankton populations drop off, ...

Global warming will melt over 1/3 of the Himalayan ice cap by 2100

Asia’s Himalayan mountain range is about to undergo some major changes. New research predicts that global warming will melt at least one-third or up two two-thirds of the glaciers in the region by the year 2100, significantly affecting the 2 billion people who call the mountainous area home. The alarming prediction will come to pass if global carbon emissions continue at their current rates. Even more disturbing is that one-third of the glaciers in the Himalaya and Hindu Kush range will still d...

Scientists Have Reduced the Forecast of Sea Level Rise Seven Times Due To Melting of the Antarctic (slashdot)

The destruction of the Antarctic ice sheet may not lead to such a catastrophic rise in the level of the oceans, as previously thought. In a new study, the authors calculated that instead of growing by a meter or more by 2100, a growth of 14-15 cm is likely, writes N + 1. At the same time, the melting of the ice of Greenland and Antarctica is not fully taken into account in modern climate models, as it will lead to even more destabilization of the regional climate. Both studies on this are publis...

Antarctic Seach for "Endurance" Shackleton ship

I know several users, myself included, recently read the book about this ship. "Antarctic search closes in on Endurance, the lost ship of explorer Ernest Shackleton. An ambitious expedition to locate explorer Sir Ernest Shackleton’s ship Endurance is closing in on the Antarctic wreck site. Endurance, which was lost in an ice floe off Antarctica more than 100 years ago, is one of the world’s most famous undiscovered shipwrecks. The search team, however, is conducting its work in one of the har...

Study of Arctic fishes reveals the birth of a gene -- from 'junk'

Though separated by a world of ocean, and unrelated to each other, two fish groups - one in the Arctic, the other in the Antarctic - share a surprising survival strategy: They both have evolved the ability to produce the same special brand of antifreeze protein in their tissues. A new study describes in molecular detail how the Arctic fishes built the gene for their antifreeze from tiny fragments of noncoding DNA, regions once considered ''junk DNA.''

European colonizers killed so many indigenous Americans that the planet cooled down, a new study reveals

Following Christopher Columbus' arrival in North America in 1492, violence and disease killed 90% of the indigenous population — nearly 55 million people — according to a new study. Diseases like smallpox, measles, and influenza, which colonizers brought to the Americas, were responsible for many millions of deaths. The new research also reveals that following this rapid population decline and the subsequent reduction in land use, there was a global cooling trend. Prior to Columbus's arrival ...

NASA finds cavity the size of Manhattan underneath Antarctic glacier

NASA just made a disturbing discovering underneath the Antarctic ice. A team led by the space agency found a huge cavity — around 1,000 feet high — under a glacier in Antarctica, and it is steadily expanding in size. Experts have predicted they would a large cavity somewhere underneath the Thwaites Glacier, which is located in West Antarctica, but they did not expect such a large one between the ice sheet and bedrock. NASA scientists discovered the expansive chamber using a mix of radar and sat...

In a hidden lake far below the Antarctic ice, scientists found the bodies of tiny creatures. Photos reveal how they accomplished the deep dive.

Scientists recently drilled 3,500 feet deep into the Antarctic ice to the subglacial Lake Mercer —a lake that had been untouched for thousands of years. They pulled up samples of water, ice, and lake mud from the depths for further study. When analyzing the mud, researchers found the carcasses of tiny crustaceans and a tardigrade. The research team has shared additional images and video from their foray into the icy depths. Take a look. Scientists know more about the surface of Mars than the...

Melting ice sheets may cause 'climate chaos': study

Billions of tonnes of meltwater flowing into the world's oceans from the Greenland and Antarctic ice sheets could boost extreme weather and destabilise regional climate within a matter of decades, researchers said Wednesday. Known as the Atlantic Meridional Overturning Circulation (AMOC), this liquid conveyor belt plays a crucial role in Earth's climate system and helps ensures the relative warmth of the Northern Hemisphere. "According to our models, this meltwater will cause significant disru...

The Colonization of the Americas Cooled the Earth

A new paper from researchers at University College London argues that the genocide of indigenous peoples in the Americans after Columbus’s landing in 1492 had a significant effect on the Earth’s global climate and was a major cause of the Little Ice Age, the dip in global temperatures from the 16th to the 19th centuries. They estimate that 55 million indigenous people died during Europe’s conquest of the Americas (~90% of the population), and the 56 million hectares of land that they had cleared...

House lawmakers finally let climate scientists set the record straight

For the past couple of years, the Republican-led U.S. House of Representatives Committee on Science, Space and Technology has publicly disparaged and disputed climate science.  The lawmaking committee's official Twitter account promoted blogs from Breitbart News arguing that the climate is cooling, called the government's own 2,000-page climate report "a press release from environmental pressure groups," and cited an article that labeled the historic Paris climate agreement a "fossil-f...

Melting ice sheets may cause 'climate chaos' according to new modelling

The weather these days is wild and will be wilder still within a century. In part, because the water from melting ice sheets off Greenland and in the Antarctic will cause extreme weather and unpredictable temperatures around the globe. A study published today in Nature is the first to simulate the effects, under current climate policies, that the two melting ice sheets will have on ocean temperatures and circulation patterns as well as on air temperatures by the year 2100.

Don’t forget about the colossal Himalayan glaciers. They’re rapidly vanishing, too.

The Himalayas pierce the sky. But they've been overshadowed.  The accelerated melting in the Arctic — the fastest warming region on Earth — and the Antarctic — home to the largest ice sheets on the planet — certainly demand widespread scientific and media attention. Yet beyond the continually grim news from the north and south poles is the melting of the "third pole," known as the Hindu Kush Himalaya region. Spreading over 2,000 miles across eight nations (from Afghanistan to Myanmar), thes...

A tiny dinosaur relative named the "Antarctic King” has been discovered at the South Pole

Paleontologists have unearthed a new dinosaur relative in the rocks near the South Pole.  They named it Antarctanax shackletoni, or "Antarctic king." It was a carnivorous reptile about the size of an iguana that lived roughly 250 million years ago. The fossil gives scientists new insight into what Antarctica (and the rest of the world) looked like during the time after a mass extinction. The Antarctica of 250 million years ago was a far cry from today's icy landscape. At the time, the contine...

Before There Were Dinosaurs, This Triassic 'Lizard King' Ruled Antarctica

Millions of years before the ground trembled under the footfalls of T. rex -- the so-called "king of the dinosaurs" -- a forested Antarctica was home to an iguana-size "lizard king." This ancient reptile was an archosaur -- part of the same group that would later include dinosaurs, pterosaurs and crocodilians. Scientists recently discovered a partial skeleton of the lizard dating to 250 million years ago, a time when Antarctica was bursting with plant and animal life. Not only does the fossil ...

Don’t worry, this rocket-launching Chinese robo-boat is strictly for science

It seems inevitable that the high seas will eventually play host to a sort of proxy war as automated vessels clash over territory for the algae farms we’ll soon need to feed the growing population. But this rocket-launching robo-boat is a peacetime vessel concerned only with global weather patterns. The craft is what’s called an unmanned semi-submersible vehicle, or USSV, and it functions as a mobile science base — and now, a rocket launch platform. For meteorological sounding rockets, of course...
