But what's concerning about Pine Island Glacier is that it's calving icebergs more frequently than it used to, Lhermitte said. In West Antarctica, Pine Island Glacier and Thwaites Glacier have been melting at alarming rates, according to satellite imagery over the ice continent. Future US, Inc. 11 West 42nd Street, 15th Floor,
A new study from Northwell Health, the largest health system in New York State, aims to find out. The idea highlights a paradox in thermodynamics. Please refresh the page and try again.

Specifically, the accompanying image (from the website) illustrates how rifting (cracking) of the Pine Island Ice Shelf, PIIS, has increased from 1973 to 2011, while comparing the shape of the 2011 calving face with the current calving face (see prior posts in this thread), shows how rapidly the calving has accelerated in the past two years (as compared to the 1973 to 2011 period). That could set off unstoppable retreat of Pine Island Glacier. This phenomenon of calving isn't new for Pine Island Glacier, according to the ESA. Thus it would decrease its entropy, moving it further away from equilibrium.,
Ludwig Boltzmann. Around this time, Pine Island Glacier started to shed smaller icebergs more frequently. The Pine Island glacier in #Antarctica has finally calved, creating many large icebergs! Today, the glacier is observed to be losing mass by a combination of calving events together with strong basal melting, where warm ocean currents erode the underside of the floating ice shelf. While large calving events used to occur at Pine Island Glacier every four to six years, they've now become a near-annual occurrence, according to NASA. Pine Island Glacier (PIG) is a large ice stream, and the fastest melting glacier in Antarctica, responsible for about 25% of Antarctica's ice loss. It's doubly (trebly?!) Pine Island Glacier, one of the fastest-shrinking glaciers in Antarctica, has just lost another huge chunk of ice to the sea, continuing a troubling trend that has become a near-annual occurrence in the last decade. Scientists worry that this persistent retreat could be a sign that a runaway melting cycle is in effect: As comparatively warm sea water laps at the newly exposed edges of an ice shelf, melting accelerates, the ice shelf stretches and thins, and further calving becomes ever more likely. The irreversible collapse of the West Antarctic ice sheet would raise sea levels 20 feet, says the UN. On its own, the recent calving event is not entirely surprising or particularly threatening to global sea levels; calving is a normal part of life for ice formations with sections that float on the water, according to NASA's Earth Observatory. Published on Sep 25, 2017 Antarctica just lost another huge piece of ice. Thank you for signing up to Live Science.,
When we reframe [gun violence] as a public health issue, then we're able to use the same strategies that we've used to decrease car-crash deaths, decrease infections and deaths from HIV, and reduce injuries and deaths from a host of other problems.,
The paradox of the Boltzmann Brain can really pull the rug from under you if you follow it to all of its logical and illogical extents. Let's look at the underlying thinking.
Our Universe is extremely vast and complex, still filled with as much of the unimaginable as what we have already figured out. Pine Island's newest icebergs calved just days after scientists reported the hottest temperature ever recorded in Antarctica. There is a lot we don't know about psychedelics, but what we do know makes them extremely important. worrisome on the heels of the above UN IPCC report, which basically tells us we're screwed unless we take drastic actionâand, I mean drasticâin order to curb emissions and slow the inexorable drift into an Earth that looks like one of those terrifying science fiction novels. "There's a tremendous amount of insight that can be plumbed using these various substances. "So, how can we target screening if we don't even know the basic elements of a public health approach?"
The collected data will help health professionals develop better models for predicting who's most at risk of gun violence. However, over the past two decades, calving events have been occurring much more frequently at Pine Island Glacier and the neighboring Thwaites Glacier (also known as the "Doomsday Glacier") as the surrounding ocean warms due to global warming. The goal is to encourage firearm safety, educate at-risk patients on violence-prevention resources, and normalize doctor-patient conversations about gunsânot stigmatize gun ownership or infringe upon individual rights.What's even more concerning about the Pine Island Glacier's calving event is that it happened right next to the Thwaites Glacier, which is so at risk it's called the "Doomsday Glacier". It's the sixth large-calving event from this glacier since 2001. Recently, the frequency of Pine Island Glacier calving events has increased. Calving Icebergs Pine Island Glacier ice shelf periodically calves huge icebergs. miles in sizeâ4.5x the size of Manhattan. A large calving event on Pine Island Glacierâs ice shelf in February 2020, observed from the Corpernicus satellite.
- Do you have a gun at home?

These types of entities have been dubbed "Boltzmann Brains" by modern physicists Andreas Albrecht and Lorenzo Sorbo. They did not claim to such brains really being in existence but rather used the idea to point out the absurdities and limitations of taking the idea of thermodynamic fluctuations to their extent.
Boltzmann Brains have also been criticized as philosophical paradoxes that are experientially unprovable. About one year ago, in Antarctica, the Pine Island Glacier You will receive a verification email shortly. 1901,
From the physicist's work it follows that it would be more likely for random quantum fluctuations in nature to create something simpler than our astounding Universe â for example, a self-aware entity that believes it is a person in a world full of people, history, and particular physics. On Thursday (Feb. 6), temperatures near a research base on the continent's northern edge reached 64.9 degrees Fahrenheit (18.3 degrees Celsius), the World Meteorological Organization reported. Several experiments over the past decades have shown that, when used correctly, drugs like psilocybin and LSD can have positive effects on the lives of those take them. The ice block the core was taken from, still covered in ashes. How they work is not completely understood, but the empirical evidence shows promise in the fields of curbing depression, anxiety, obsession, and even addiction to other substances. And your sense of self is just a statistical fluctuation. Vote like your lives depend on it, folks. Pine Island Glacier: the movie. Dr. Sathya and Mr. Dowling are spearheading Northwell's gun-violence prevention efforts, including the "We Ask Everyone. Pine Island Glacier, along with its neighbour Thwaites Glacier, connect the centre of the West Antarctic Ice Sheet with the ocean â together discharging significant quantities of ice into the ocean. NASA reports that these events used to take place on four to six year intervals, however, calving of the glacier has become a yearly occurrence. It may be more likely for a Boltzmann Brain to come into existence than the whole Universe. The previous record was 63.5 F (17.5 C), set in March 2015. 5. The area of the iceberg poised to calve off the Pine Island Glacier is about 115 square miles, or 300 square kilometers. The goal is to destigmatize doctor-patient conversations about guns, and reframe gun violence as a public health issue. The calving mechanism of tabular icebergs is one of the major unknowns in glaciology and hence calving events at locations where the glaciological variables of ice shelves or ice tongues are well known are ideal natural setups for studying these mechanisms.Death in the past 2,000 years ice loss has substantially increased over last...
