A Changing Earth

"What is the reason for a decreased fertility rate? An environment poised by an exponential growing human society, a famine, a war for resources or self-determined family planing in an pieceful equal society?

An non-growing population requires fundamental changes in our society, just increasing the retirement age or pass the problem to the next generation are certainly not the structural changes we need for a peaceful society. Old people must life in dignity and the young generation must know for themselves, that they can get old in dignity. Scientific progress allows us to preserve our planet and create affluent societies, instead it seems that human societies are focused on the development of new deadly weapons and new information systems are used as tools for tax avoidence and social control, to create international organization, lobbying for there own purposes, whatever that might be.

Is the motion of the geomagnetic field an unstable physical process? Then collecting data will help, but it is not enough to understand this phenomenon. I think we need to understand the qualitative nature of the geomagnetic field changes. Maybe societies should not create atomic explosions in the earth mantle before they really understand this instability. The research could lead in the future to artificial magnetic fields for space ships.

Nice - but why not using an electrical leaf blower. They are not as noisy and won't add to the climate change, which replaces in the near future hardwood forests in southern parts of the U.S and Europe.

"Tiny solid and liquid particles suspended in the atmosphere are called aerosols. Windblown dust, sea salts, volcanic ash, smoke from wildfires, and pollution from factories are all examples of aerosols. Depending upon their size, type, and location, aerosols can either cool the surface, or warm it. They can help clouds to form, or they can inhibit cloud formation. And if inhaled, some aerosols can be harmful to people's health."

"These maps show average monthly aerosol amounts around the world based on observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite. Satellite measurements of aerosols, called aerosol optical thickness, are based on the fact that the particles change the way the atmosphere reflects and absorbs visible and infrared light. An optical thickness of less than 0.1 (palest yellow) indicates a crystal clear sky with maximum visibility, whereas a value of 1 (reddish brown) indicates very hazy conditions."

"According to the report, food production to meet the complex demands of an expanding human population is leading the race in the destruction of habitats and overexploitation of wildlife. At present, agriculture occupies about one-third of the Earth’s total land area and accounts for almost 70 per cent of water use."

"The report’s findings provide additional evidence that the planet is entering completely unchartered territory in its history in which humanity is shaping changes on the Earth, including a possible sixth mass extinction. Researchers are already calling this period the Anthropocene. Understanding why we are moving into this new epoch enables us to identify solutions for restoring the ecosystems we depend upon"


"Living Planet Report 2016 draws on leading research about the scale and impact of human activity on our planet. One such framework, developed by the Stockholm Resilience Centre in collaboration with partners, demonstrates that humanity has surpassed four out of nine Planetary Boundaries – safe thresholds for critical Earth system processes that maintain life on the planet."

....

"The report also features research from the Global Footprint Network that shows that while we only have one Earth, humanity is currently using the resources of 1.6 planets to provide the goods and services we use each year. "

"No matter how you add it up, the math does not look good. The more we continue to exceed Earth’s limits, the more damage we do to our own future,” said Lambertini. “We are at a decisive moment in time when we can seize the solutions to steer our food, energy and finance systems in a more sustainable direction.” 

.... and sieze peaceful solutions to seize or own population growth, which is the root of the problem.

"All the measurements in the world do not balance one theorem by which the science of eternal truths is actually advanced." - Carl Friedrich Gauss

"Understanding the Great Red Spot is not easy, and it’s mostly Jupiter’s fault. A planet a thousand times as big as Earth, Jupiter consists mostly of gas. A liquid ocean of hydrogen surrounds its core, and the atmosphere consists mostly of hydrogen and helium. That translates into no solid ground like we have on Earth to weaken storms. Also, Jupiter’s clouds obstruct clear observations of its lower atmosphere. While some studies of Jupiter have investigated areas in its lower atmosphere, orbiting probes and telescopes studying the Great Red Spot can only see clouds scattered high in the atmosphere."

"Amy Simon, an expert in planetary atmospheres at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, said learning more about Jupiter and its Great Red Spot could help scientists understand Earth’s weather system better. Jupiter’s weather functions under the same physics as Earth, she said, just millions of miles farther from the sun. Simon also said Jupiter studies could improve our understandings of worlds beyond our solar system. “If you just look at reflected light from an extrasolar planet, you’re not going to be able to tell what it’s made of,” Simon said. “Looking at as many possible different cases in our own solar system could enable us to then apply that knowledge to extrasolar planets.”"


I found an wonderful mathematical Ansatz for the description of cyclones. I think it will result in an explanation of the persistence of the Great Red Spot and even more important, in an better analytical understanding of cyclones on earth. Is there an scientific institute on earth, interested to support the write up?

"But the physics are so complex that scientists could only guess at how this actually works in the real world. Now, Adhikari has proposed a way to explain the process. The secret was discovering that it's not just shrinking glaciers that change Earth's mass distribution, as some scientists had thought. A lot of mass also gets moved around due to large-scale loss of liquid water from the land, the team reports this week in Science Advances."

Why not building (print) an small scale earth model for the International Space Station, which contains the essential ice shields and a ground water model? Let it rotate in zero gravity and see what happens to the rotation axis during changes of the ice sheets and the ground water model distribution.
The results can then be used to verify theoretical calculations, which I think are workable, at least qualitatively.

"Gavin Schmidt, a climate scientist with NASA's Goddard Institute for Space Studies in New York, commends the authors for adding to the discussion about climate science. Schmidt, who was not affiliated with the study, agrees that human activity has caused "detectable shifts in mass from ice sheet melt and groundwater extraction." "
