August 2, 20214 yr Eternal Change for No Energy: A Time Crystal Finally Made Real (Don't know if this is reproduceable and it is subject to a peer review, but if accurate it will probably be the greatest discovery in our lifetime.) Quote In a preprint posted online Thursday night, researchers at Google in collaboration with physicists at Stanford, Princeton and other universities say that they have used Google’s quantum computer to demonstrate a genuine "time crystal.” In addition, a separate research group claimed earlier this month to have created a time crystal in a diamond. A novel phase of matter that physicists have strived to realize for many years, a time crystal is an object whose parts move in a regular, repeating cycle, sustaining this constant change without burning any energy. "The consequence is amazing: You evade the second law of thermodynamics,” said Roderich Moessner, director of the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany, and a co-author on the Google paper. That’s the law that says disorder always increases. Time crystals are also the first objects to spontaneously break "time-translation symmetry,” the usual rule that a stable object will remain the same throughout time. A time crystal is both stable and ever-changing, with special moments that come at periodic intervals in time. The time crystal is a new category of phases of matter, expanding the definition of what a phase is. All other known phases, like water or ice, are in thermal equilibrium: Their constituent atoms have settled into the state with the lowest energy permitted by the ambient temperature, and their properties don’t change with time. The time crystal is the first "out-of-equilibrium” phase: It has order and perfect stability despite being in an excited and evolving state..... https://www.quantamagazine.org/first-time-crystal-built-using-googles-quantum-computer-20210730/

August 6, 20214 yr Climate Change Could Shut Down A Vital Ocean Current, Study Finds https://www.yahoo.com/news/climate-change-could-shut-down-220313885.html Human-driven planetary warming threatens to collapse a system of currents in the Atlantic Ocean that regulate and impact weather across the globe, a new scientific study has found. The Atlantic Meridional Overturning Circulation, or AMOC, a section of the Gulf Stream, transports warm water from the tropics northward and cold water from the North Atlantic to the south. This natural redistribution of heat has long worked to stabilize regional climate and weather conditions; however, scientists have been warning that the system is slowing down. A 2019 United Nations report concluded that while the current is "very likely” to weaken this century, a total breakdown was unlikely. But the new study, published Thursday in the journal Nature Climate Change, indicates the situation could be far direr than previously thought. The current changes may be tied to "an almost complete loss of stability of the AMOC over the course of the last century,” the analysis states. "The findings support the assessment that the AMOC decline is not just a fluctuation or a linear response to increasing temperatures but likely means the approaching of a critical threshold beyond which the circulation system could collapse,” Niklas Boers, a researcher at the Potsdam Institute for Climate Impact Research in Germany and the study’s author, said in a statement. A crippled Atlantic current system could trigger catastrophic, potentially irreversible changes, from rising seas in North America to major disruptions to seasonal monsoon rains in Asia and South America. "The mere possibility that the AMOC tipping point is close should be motivation enough for us to take countermeasures,” Levke Caesar, a climate physicist at Ireland’s Maynooth University, told The Washington Post. "The consequences of a collapse would likely be far-reaching.” But Andreas Schmittner, a climate scientist at Oregon State University, is skeptical of the study’s conclusion. "The method used in the paper has been developed and tested in very simple models of dynamical systems, but then it is applied to observations of sea surface temperatures and salinities,” he told HuffPost in an email. "I think their method is brand new and needs to be tested by different investigators and explored more in complex climate models to see if it works with the data they used. I think it is premature to conclude that the AMOC is on the brink of collapse.” The study comes ahead of a major report from the United Nations’ Intergovernmental Panel on Climate Change, or IPCC, the leading consortium of researchers studying human-caused temperature rise. The assessment, due out Aug. 9 and authored by more than 200 scientists, will provide an up-to-date understanding of the crisis and its current and future effects around the globe. There’s no way to pinpoint the level of greenhouse gas emissions that would lock in a total collapse of the AMOC, Boers told The Guardian. "The only thing to do,” he said, "is keep emissions as low as possible. The likelihood of this extremely high-impact event happening increases with every gram of CO2 that we put into the atmosphere.”
August 9, 20214 yr https://www.yahoo.com/news/key-takeaways-u-n-climate-080000988.html?.tsrc=fp_deeplink Aug 9 (Reuters) - The U.N. climate panel has released its most comprehensive assessment https://www.ipcc.ch/report/ar6/wg1 of climate change yet. Here are some of the report's main conclusions: HUMANS ARE TO BLAME - FULL STOP The Intergovernmental Panel on Climate Change (IPCC) used its strongest terms yet to assert that humans are causing climate change, with the first line of its report summary reading: "It is unequivocal that human influence has warmed the atmosphere, ocean and land." The stark language marked a shift from previous IPCC reports, which had said it was "extremely likely" that industrial activity was to blame. "There is no uncertainty language in this sentence, because there is no uncertainty that global warming is caused by human activity and the burning of fossil fuels," said IPCC co-author Friederike Otto, a climatologist at University of Oxford. TEMPERATURES WILL KEEP RISING The report describes possible futures depending on how dramatically the world cuts emissions. But even the severest of cuts are unlikely to prevent global warming of 1.5 degrees Celsius above preindustrial temperatures. Without immediate steep emissions cuts, though, average temperatures could cruise past 2C by the end of the century. The scientists also looked at events considered less likely but still possible, and they could not rule out big impacts from so-called tipping points, such as the loss of Arctic ice loss or the dieback of forests. WEATHER IS GETTING EXTREME Weather extremes once considered rare or unprecedented are becoming more common — a trend that will continue even if the world limits global warming to 1.5C. Severe heat waves that happened only once every 50 years are now happening roughly once a decade. Tropical cyclones are getting stronger. Most land areas are seeing more rain or snow fall in a year. Severe droughts are happening 1.7 times as often. And fire seasons are getting longer and more intense. ARCTIC SUMMERS COULD SOON BE FREE OF ICE Summertime sea ice atop the Arctic Ocean will vanish entirely at least once by 2050, under the IPCC's most optimistic scenario. The region is the fastest-warming area of the globe - warming at least twice as fast as the global average. While Arctic sea ice levels vary throughout the year, the average lows during summer have been decreasing since the 1970s and are now at their lowest levels in a thousand years. This melting creates a feedback loop, with reflective ice giving way to darker water that absorbs solar radiation, causing even more warming. SEAS WILL RISE NO MATTER WHAT Sea levels are sure to keep rising for hundreds or thousands of years. Even if global warming were halted at 1.5C, the average sea level would still rise about 2 to 3 meters (6 to 10 feet), and maybe more. Sea level rise has picked up speed, as polar ice sheets melt and warming ocean water expands. Already, associated flooding has nearly doubled in many coastal areas since the 1960s, with once-in-a-century coastal surges set to occur once a year by 2100. Scientists could not rule out extreme rises of more than 15 meters by 2300, if tipping points trigger runaway warming. "The more we push the climate system ... the greater the odds we cross thresholds that we can only poorly project," said IPCC co-author Bob Kopp, a climate scientist at Rutgers University. RUNNING OUT OF TIME Meeting the Paris Agreement goal of limiting warming to 1.5C will require sticking to a "carbon budget," a term describing how much additional carbon can be pumped into the atmosphere before that goal is likely out of reach. The world is now on track to use up that budget in about a decade. With 2.4 trillion tons of climate-warming CO2 added to the atmosphere since the mid-1800s, the average global temperature has risen by 1.1C. That leaves 400 billion tons more that can be added before the carbon budget is blown. Global emissions currently total a little more than 40 billion tons a year.

The only thing that Gus possibly did wrong was arming the hatch, but unarmed, it isn't an escape, so I can understand why he armed it as soon as he could. It sure looks like when the helicopter approached, an arc of static caused the explosive hatch to blow. I am glad they are finally unsmearing poor Gus' reputation.
