Penguins are seen on an iceberg as scientists investigate the impact of climate change on Antarctica's penguin colonies, on the northern side of the Antarctic peninsula, Antarctica January 15, 2022. There's no quick fix to replacing this ice," said Caroline Holmes, polar climate scientist at British Antarctic Survey and one of the study's co-authors. The precise impact of climate change on Antarctica and the surrounding ocean has been uncertain and scientists have struggled to measure how much global warming is affecting the thickness of Antarctic ice. "Antarctica is fragile as an environment, but extreme events test that fragility," he said. "What we're deeply concerned about is the increase in intensity and frequency of extreme events and the cascading influences that they have in other areas."

In Italy, which has been particularly hard hit, temperatures in many cities are expected to soar above 40 degrees Celsius (104 Fahrenheit). In Spain, temperatures in the cities of Seville, Cordoba and Granada have reached 40 degrees Celsius. Even the normally cooler region of Navarra in the north of the country is experiencing up to 40 degrees Celsius. Firefighters have controlled the fire and it’s not yet clear if the region’s high temperatures played any role. While in the US, California’s Death Valley reached nearly 52 degrees Celsius (125.6) on Sunday.

GENEVA, July 10 (Reuters) - Antarctic sea ice levels reached record lows last month, the World Meteorological Organization (WMO) said on Monday, a development climate change experts described as worrisome. WMO said that Antarctic sea ice levels last month - the hottest June ever recorded -- were at their lowest since satellite observations began, at 17% below average. "We're used to seeing these big reductions in sea ice in the Arctic, but not in the Antarctic. This is a massive decrease," Michael Sparrow, Chief of World Climate Research Programme, told reporters in Geneva. "Alarm bells are ringing especially loudly because of the unprecedented sea surface temperatures in the North Atlantic."

The WMO said there was a 90% probability of El Niño continuing during the second half of 2023 at moderate strength. Along with increased ocean warming, El Niño events are usually associated with increased rainfall in parts of southern South America, the southern United States, the Horn of Africa and central Asia. In India, a major rice producing nation, El Niño can weaken the monsoon that brings the rainfall the country relies on to fill aquifers and grow crops. El Niño this year could also dent US economic growth, potentially impacting everything from food prices to winter clothing sales, a recent study found. The study attributed $5.7 trillion in global income losses to the 1997-98 El Niño and $4.1 trillion in losses to the 1982-83 El Niño.

CNN —For the first time, astronomers have assembled a glowing portrait of the Milky Way galaxy using cosmic “ghost particles” detected by a telescope embedded in Antarctica’s ice. Over the years, astronomers have showcased stunning images of the Milky Way through electromagnetic radiation from visible light or radio waves. These tiny, high-energy cosmic particles are often referred to as ghostly because they are extremely vaporous and can pass through any kind of matter without changing. The IceCube detector is seen under a starry night sky, with the Milky Way appearing over low auroras in the background. Cosmic rays are mostly made up of protons or atomic nuclei that have been stripped from atoms, according to NASA.

Record high levels of carbon pollution in the atmosphere and record low levels of Antarctic ice. Several all-time heat records were also broken earlier this month in Siberia, as temperatures shot up above 100 degrees Fahrenheit. In 2022, the world’s oceans broke heat records for the fourth year in a row. In late February, Antarctic sea ice reached its lowest extent since records began in the 1970s, at 691,000 square miles. The decline in sea ice also poses severe harm to the continent’s species, including penguins who rely on sea ice for feeding and hatching eggs.

What do you call the arrival of events that have been predicted but, when predicted, were described as distressing or even terrifying? But some news from ocean science may prove more surprising still — perhaps genuinely paradigm-shifting. This key part of the circulation of the Southern Ocean “looks headed towards collapse this century,” study coordinator Matthew England told Yale Environment 360. “And once collapsed, it would most likely stay collapsed until Antarctic melting stopped. At current projections that could be centuries away.”Then, last week, some of the same researchers confirmed that the process was already unfolding — in fact, that the Southern Ocean overturning circulation had already slowed by as much as 30 percent since the 1990s.

The ocean is pulled down to Earth due to gravity, despite a viral post shared online falsely claiming that the planet’s oceans are held inside a “container,” with Antarctica forming the external ridge. The posts allude to flat earth conspiracies. OUR CONTAINER.”The ocean is pulled down to the irregular ellipsoid-shaped Earth due to gravity (here), however, and is not held together by containers on a flat surface.

☆ Greenland and Antarctic ice sheets are melting rapidly and driving sea level rise, new satellite data finds
▼ + stars: | 2023-04-20 | by ( Jack Guy | ) edition.cnn.com time to read: +4 min

CNN —The Earth’s ice sheets lost enough ice over the last 30 years to create an ice cube 12 miles high, according to new research. They found that ice sheet melting has increased six-fold over the past 30 years, as record levels of planet-heating pollution push up global temperatures. The worst year for ice sheet loss was 2019, the report found, when the ice sheets lost around 675 billion tons of ice. Ice sheet melting now accounts for a quarter of all sea level rise – a fivefold increase since the 1990s. Otosaka expects the Greenland ice sheet to continue losing ice, but said it’s not yet clear what might happen to the Antarctic ice sheet.

☆ Rising Antarctic ice melt will dramatically slow global ocean flows, study finds
▼ + stars: | 2023-03-29 | by ( David Stanway | ) www.reuters.com time to read: +3 min

REUTERS/Natalie Thomas/SINGAPORE, March 29 (Reuters) - Rapidly melting Antarctic ice is dramatically slowing down the flow of water through the world's oceans, and could have a disastrous impact on global climate, the marine food chain and even the stability of ice shelves, new research has found. The "overturning circulation" of the oceans, driven by the movement of denser water towards the sea floor, helps deliver heat, carbon, oxygen and vital nutrients around the globe. But deep ocean water flows from the Antarctic could decline by 40% by 2050, according to a study published on Wednesday in the journal Nature. Ocean overturning allows nutrients to rise up from the bottom, with the Southern Ocean supporting about three-quarters of global phytoplankton production, the base of the food chain, said a second study co-author, Steve Rintoul.

Melting ice that could tip sea level rise into catastrophic levelsSource: NASA Ice ViewerChart: Annie Fu/InsiderWhile it's easier to plan for a steady sea level rise, scientists are very concerned about what would happen if huge chunks of ice collapse and abruptly change sea levels. The Antarctic ice sheet is much bigger than the ice sheet on Greenland. If they were to melt totally, the Greenland ice sheet would contribute about 23 ft to the sea levels, while the Antarctic ice sheet holds enough ice to raise sea levels by 58 feet. Local sea level variationGlobal mean sea level rise is only a snapshot of the whole picture. Because sea levels are influenced by the local environment, the sea level rise can be much higher locally than it is on a global scale.

Martin Leonhard of the East Greenland Ice-Core Project (EastGRIP) operates snow blower putting a new snow floor for the winter-storage weather port tent at EastGRIP camp on August 9, 2022. EastGRIP is an international science station on the Greenland ice sheet, the second-largest ice body in the world after the Antarctic ice cap. The researchers described how hotter air temperatures, melting sea ice, shorter periods of snow cover, increased wildfire and rising levels of precipitation have forced wildlife and Indigenous people in the region to adapt. The Arctic's seven warmest years since 1900 have been the last seven years, and researchers pointed to a slew of signs that the region is undergoing a dramatic shift. Scientists also noted that maritime ship traffic is on the rise in the Arctic as sea ice declines, with the most notable increases in traffic occurring among ships traveling from the Pacific Ocean through the Bering Strait and Beaufort Sea.

Neutrinos are accelerating toward Earth from the center of a galaxy known as Messier 77, according to a new study. A gigantic observatory buried in the Antarctic ice has helped scientists trace elusive particles called neutrinos back to their origins at the heart of a nearby galaxy—offering a new way to study a supermassive black hole shrouded from view. According to a new study published Thursday in the journal Science, neutrinos are accelerating toward Earth from the center of a spiral-shaped galaxy known as Messier 77, which is about 47 million light years from Earth. There, a matter- and radiation-dense region surrounds a black hole many millions times as massive as our sun.

The agency’s review followed a 2011 petition by the environmental group Center for Biological Diversity to list the bird under the Endangered Species Act. Tuesday’s designation was described as a warning that emperor penguins need “urgent climate action” in order to survive by Shaye Wolf, the climate science director at the Center for Biological Diversity. The 1973 Endangered Species Act is credited with bringing several animals back from the brink of extinction, including grizzly bears, bald eagles, gray whales and others.

Alarming reports that the Antarctic ice sheet is shrinking misrepresent the science under way to understand a very complex situation. The ice sheet holds about 26.5 million gigatons of water (a gigaton is a billion metric tons, or about 2.2 trillion pounds). Much more modest ice loss is normal in Antarctica. The difference between the discharge and addition each year is the ice sheet’s annual loss. That figure has been increasing in recent decades, from 40 gigatons a year in the 1980s to 250 gigatons a year in the 2010s.
