I’m back with the latest observations on sea level rise. !7-06-2023.
It’s not just the glaciers that are to blame. I have always been opposed to the consumption of the critical groundwater table, during periods of drought. The following are excerpts from a number of scientific data that I think may be of interest.
It is not just about the risk of groundwater shortages, but larger problems such as the earth’s rotation and angle!!
By pulling groundwater out of the ground and moving it elsewhere, humans have displaced a body of water so large that the Earth tilted almost 80 centimeters to the east between 1993 and 2010 alone.
Based on climate models, new research published in Geophysical Research Letters previously estimated that humans pumped 2,150 gigatons of groundwater, equivalent to more than 6 millimeters of sea level rise, between 1993 and 2010. But validating that estimate is difficult. .
One approach lies in the Earth’s pole of rotation, which is the point around which the planet revolves. It moves during a process called polar motion, which is when the position of Earth’s pole of rotation varies relative to the crust. The distribution of water on the planet affects how mass is distributed. Like adding a bit of weight to a spinning top, the Earth spins a bit differently as the water moves.
“Earth’s pole of rotation actually changes a lot,” Ki-Weon Seo, a geophysicist at Seoul National University who led the study, said in a statement. “Our study shows that, among climate-related causes, groundwater redistribution actually has the largest impact on rotational pole drift.”
The ability of water to change Earth’s rotation was discovered in 2016, and the specific contribution of groundwater to these rotational changes had not been explored until now. In the new study, the researchers modeled the observed changes in Earth’s pole rotation drift and water movement, first considering only ice sheets and glaciers, and then adding different groundwater redistribution scenarios.
Attempts by countries to reduce rates of groundwater depletion, especially in those sensitive regions, could theoretically alter the drift, but only if such conservation approaches are sustained for decades, Seo said.
The pole of rotation normally changes several meters in about a year, so changes due to groundwater pumping do not risk changing the seasons. But on geologic time scales, polar drift can have an impact on climate, Adhikari said.
The next step in this investigation could be to look into the past. “Observing changes in the Earth’s pole of rotation is useful for understanding variations in water storage on a continental scale,” Seo said. “Polar motion data has been available since the late 19th century. Therefore, we can use these data to understand variations in inland water storage over the last 100 years. Was there any change in the hydrologic regime as a result of global warming? climate? Polar movement could hold the answer.”
The importance of groundwater and how to maintain it.
Stormwater, and the importance of collection, by #Watersupply.es
Gathering:
Rainwater is collected from the roofs of buildings and from permeable soil
surfaces.
Storage:
The collected water is stored in underground storage tanks, (storm-tanks).
Filtration:
The system includes a filtration process to remove impurities from the water
before storage or use or will be directed to a final filtration (treatment) for
drinkable water.
Infiltration:
Some of the water infiltrates the soil through permeable pavements, which
reduces surface runoff and recharges aquifers, that finally gives groundwater.
Reuse:
The stored water can be reused for non-potable purposes such as irrigation,
cleaning or flushing toilets.
The importance of groundwater, by #Watersupply.es
Drinking water:
Groundwater is an important source of drinking water for many people
and communities.
Surface water:
Groundwater affects lakes, streams and wetlands by replenishing them
with water, especially during periods of low surface water flow.
Ecosystems:Groundwater-dependent ecosystems, such as wetlands and springs,
depend on groundwater levels and flows for their survival.
Infrastructure:
Groundwater levels can affect the stability of buildings and
infrastructure, and groundwater withdrawal can lead to subsidence.
Energy:
Groundwater can be used for heat pumps and energy wells, which
harness the energy stored in the soil and rocks.
Climate impact:
Groundwater is affected by precipitation patterns and evaporation and
can help mitigate the effects of droughts and floods.
Groundwater is an important resource that needs to be protected and
managed in a sustainable manner to ensure its continued importance
for society and the environment.
Logic and reasons:
“We cannot take out, more than we bring back to nature”. My father
told me. He also said; When you cut down one three, you must plant
five.
The word ECO-System has always been in the thoughts of humanity,
just look back to the Roman Empire, when water was transported
throughout the landscape without pumping systems.
Nowadays GREED has taken over modern thinking, without thoughts
about the consequences.
We need to look back and start using Logic and Reason to rebuild what
has been done wrong.
Water Positive; has started global groundwork to gather knowledge from experts and intellectuals, which has already yielded noticeable results, and we look forward to further development.
AI; can help with advanced solutions, but we should not forget the human factor. There are a lot of people with life experiences who can
in many cases gain knowledge from these, as well as develop for
modern use.
Watersupply; members can bring over 70 years of personal life experience from agriculture, shipping and experience from hurricane
affected areas, after visiting and experiencing over 52 countries. Also,
the knowledge from the latest in floating desalination plants (FOD) and
AWG (Atmospheric Water Generation).
Summary:
All of us who work in the water industry know how important it is to get
the message out to the political leaders of the world, but also to get the
attention of the world’s population. It is an enormous amount of work
that will take a long time to complete, but this is just the beginning of a
Windmush will be back with more #Groundwater information soon.
