Climate change, ocean currents, and an ice age

As glaciers melt at the polar regions the increase in warm water that is low in salt is likely to disrupt the currents that circulate ocean waters and which keep the United Kingdom and Europe fairly warm. (Ocean currents & circulation of heat is mentioned in: Anomalous Properties of Water) Historically a large flood is now believed to have preceded a thousand year ice age on the North American continent.

In case visualization is helpful, the climate scenario of a change in ocean currents leading to extreme cold in Europe and New York State was made into an action movie: The Day After Tomorrow, 2004.

The daily temperature around the globe is visualized in a color coded map at the site climatereanalyzer.org.

The most critical events that are occurring for our long term well being is the effects of pollution on the atmosphere and the oceans, and other human changes to the environment that lead to desertification or concrete instead of wetlands, both of which also increase flood risk. Climate change will be a variety of changes, erratic differences in extreme temperature and weather changes. Climate: A New Story is a book published this month which looks at the earth as a whole and discusses human effects on the atmosphere, the oceans, wetlands, soil health and other factors that all interact to  create the planet as we have known it. Geologically we have had fairly stable climate for thousands of years but over the longer eons there has been series of ice ages and more warm eras. The planet will go on, the question has more to do with how many other species, including humans, will live to see the next centuries. (Interview with Charles Eisenstein, the author of Climate: A New Story, available in a brief article: kellybroganmd.com.)

This decade is the time humans as a global whole need to seriously reduce our collective use of fossil fuels and other chemicals adding to climate change such as agricultural fertilizers in order to stop the most extreme changes in the atmosphere and ocean from occurring. Many of the chemicals involved will take decades to even centuries to breakdown. (previous post, Climate change is a 100,000 year change.) The changes in how we live and work could create more jobs and be an economic stimulus. More information is available in this article: It’s now or never on climate change, according to a new report. huffingtonpost.com/

Hotter temperatures can make it more difficult to learn or work and can increase risk of ill health in the very young or old and those with chronic illness. Building for a future with more extreme changes in temperature is a task that is already needed in some areas as seen with the heat waves and drought that have occurred this summer and in recent years. (Effects of heat on students.) (Previous post with links about Passive Energy Buildings – architecture for a more sustainable future.)

We all need to be heroes – one hero is not enough for the planet. It needs all of us to pitch in and help, if only in small ways. I care about our future and it starts today – everyday. I write about a variety of topics because life is complex and I care about all of life. We only have one planet and we and it are healthier when there is diversity of plants and animals.  Significant changes in our daily habits could help:

  • use less prepackaged foods, use a refillable water bottle;
  • walk, ride a bicycle, use public transport or carpool;
  • arrange virtual meetings and webinar conferences when possible instead of onsite meetings when people live in many different regions;
  • have virtual stay-cations and learn about interesting foreign areas online while enjoying local recreation and nature getaways;
  • work with local and state government and businesses to develop green parks and walkways that support wildlife and exercise or pedestrian travelers, and plan and fund sustainable architecture and energy resources;
  • take online courses about climate change and sustainability; such as: Act on Climate: Steps to Individual, Community and Political ActionCoursera.

My concern has nothing to do with me, I am but a drop of life in comparison to all the beautiful species who share this planet.

  • Free course on developing local water sources to help meet future water needs, starts September 24, 2018, Local Water Solutions for Global Challenges, (GaiaEducation.org).

I am serious, as serious as a melting glacier, which I saw in person one summer, when I was young, on a family trip throughout Alaska. Glaciers were really big then – they still are big, but they are smaller now. Our planet is a miracle and we are blessed to have such a paradise in which to live, let’s take care of it for all of us including our great grandchildren and their great grandchildren. Let’s not sacrifice tomorrow’s world for today’s quarterly profit or today’s comfort when we could build toward a more equitable future for all.

Phosphonutrients, infant formula, & brain health

Good news, work on a phosphoprotein (osteopontin), found naturally in human and other mammal milk, has been refined from bovine (cow) milk and successfully used in early clinical trials with human infant formula. Babies were found to have improved immune development and reduced days with fever. See (Pediatric Ingredients: Osteopontin, by Arla Foods Ingredients, 8) for more information on the potential benefits of osteopontin as an infant formula additive for the health and development of infants.

Productivity and priorities

The word quickly and read a neuroscience textbook do not really belong in the same sentence, however setting a difficult goal and sticking with it, is one way to increase productivity. Prioritizing which goals are the most important and setting aside the less important ones also can help productivity. I wrote about dance in my last post but it was the neuroscience that was interesting to me – dance is a hobby for me, to help keep my body healthy, reading about nutrition and how it may help promote and preserve health across the lifespan – prenatal through aging – is my priority.

Neurocognitive/mental illness conditions are now affecting 20% of adults in the United States and 22% of young adults – when will prevention become a priority instead of simply prescribing medication or talk therapy? Our bodies and our minds are made from nutrients, and the ability to make more complex biochemicals from the simple nutrients, not from medication and talk.

The neuroscience text (1) is an overview of how the brain and nervous system works and it includes the topics that I have been working on for several years in more specific detail. It has been helpful to get a larger picture of which topics are known and which are still on the edge of research or at least not in a mainstream medical textbook yet. The textbook about Magnesium and the Central Nervous System goes into far more detail regarding the beneficial role of magnesium for preventative or acute health care treatment. (Previous post with a link to the Mg & CNS text, free pdf & more info about magnesium sources and symptoms of deficiency.)

It is true that the more you learn, the more you learn how much you or the field of study has yet to learn. Better health is my personal goal and sharing information for individual or population use is also a goal. My priorities or goals also include improving my skills academically, possibly working towards a graduate degree, and continuing with my current work in the area of nutrition and lifestyle for improving or preventing autoimmune and inflammatory conditions.

More tips for increasing productivity: (How to effectively get the right work done) and quotes about productivity: (100 Powerful Quotes that will boost your productivity.) Setting goals that are difficult but within reason, and stretching your capability to meet them is a trait found in super-productive people, see this article for other traits in common among productive people: (7 Traits of Super Productive People).

Productivity at the business level is similar and strategic vision might be comparable to goal setting for an individual. Having a clear vision that is flexible in how it will be achieved considered the rapid pace of change is recommended by Donald Sull of MIT Sloan School of Management: How to turn strategic vision into reality.

Spinning 101 – Vestibular system

Pause for a dance break – I’m trying to quickly read a Neuroscience textbook, (1), to get a broader background understanding of myelin before getting back to the topic of protecting myelin, promoting regeneration, and preventing demyelination. The current section of the text is about our inner ear and sense of balance and it answered a question that I have heard somewhat frequently over the years – “How can you spin like that and not get dizzy or feel queasy?”

I did have a couple semesters of ballet training in high school. I didn’t get very good however I did learn the basic moves which include pirouettes (Youtube video: How to do a Pirouette) I have always enjoyed spinning and getting a little dizzy on the playground merry-go-round that you could get going fast if you pushed it around and then jumped on, was part of the fun of spinning, however I enjoyed learning the insider tips of how ballet dancers don’t get dizzy.

Vision is part of the dizziness and the inner ear is part of the queasiness of spinning. Ballet dancers are trained to keep a visual focal point on one wall and then half way through the spin quickly turn your head 180’/half way around a circle and find a new visual focal point on the opposite wall. Spin smoothly and gracefully at an even speed, slower for beginners, and picking up speed as you improve. Dancing with your eyes closed (page 320, 1) can be another way to remove the visual dizziness factor but then you can’t see where you’re going or if other dancers are nearby.

The Neuroscience textbook gives the real inside story – our inner ear senses acceleration and deceleration of sudden motions or change in motion. Nerves from the inner ear then send a strong nerve signal about those motions to the brain but in between the acceleration and deceleration the nerve signal returns closer to a normal level of relaxation or normal sense of motion. (pp 311-312, 1)

Spinning at an even pace can be very relaxing. Personally however I always felt more balanced in my body afterwards to ‘unspin’ – spin for awhile in the other direction. Likely it helped keep muscles strengthened evenly on both sides of my body as well as giving my inner ear a workout in both directions – each ear has a matching but in reverse/mirror image set of the tubules that include the vestibular system. (Figure 14.8, page 311, 1) (Spinning in both directions, smoothly with the knee in line with the foot can help strengthen muscles in the body evenly and protect the knees – additional note – spinning intensely without slippery dance shoes can twist the knee and may lead to injury. Stretching and strengthening exercise that focus on knee stability can also help reduce risk to the knees. (Dancers & Knee Pain).

Preventative health tip – listening to very loud music or having your ear buds set to a loud volume regularly is not only risking your sense of hearing but it may also be risking your sense of balance. Loud sounds and vibrations may over stretch the delicate hair cells which turn the vibrations of sound into electrical signals that can be sent along nerve signals to the brain and the vestibular system also uses hair cells to sense the changes in angle of the head or sudden acceleration or deceleration. Hair cells can not be regenerated once they are damaged which is why loss of hearing is a common risk of aging, one in three people tend to have hearing problems as they get older.

Problems walking, and increased risk of falling, and increased risk of developing dementia have been linked to hearing loss: The Hidden Risks of Hearing Loss. (2) The increased problems with walking and falling risk are not directly linked to vestibular changes, the two areas are separate, however sound is used to judge distance from objects and help orient us in our environment while walking. Social isolation due to not hearing well is thought to be involved with the increased risk for dementia.(2)(4) Hearing aids can help with some types of hearing loss.

Safety tips for preventing hearing or vestibular damage:

  • Wearing ear plugs or noise cancelling headphones around loud noises, (5), keeping the volume at a moderate level when listening to television or music can help protect hearing, (4) and not listening to ear buds with the volume set too loud can also help protect hearing. (5) Chronic exposure to loud noise as experienced by military personnel has found that symmetrical hearing loss may have correlated vestibular damage that isn’t clear due to the damage being equal on both sides. Asymmetrical hearing loss was found to be correlated with vestibular damage on the side with hearing loss. (6)
  • Avoiding head trauma can help both the inner ear vestibular hair cells and those involved in hearing.
  • Aminoglycoside antibiotics and a few other medications have an increased risk of causing hearing loss due to damage to the hair cells; mitochondrial DNA changes may be involved as the condition can then be passed on to children by a mother with aminoglycoside related hearing loss. Taking loop diuretics along with aminoglycoside antibiotics can increase the risk of deafness occurring and exeriencing loud noise levels while taking aminoglycoside medication can also increase risk of the hearing loss damage occurring.
