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. Historically a large flood is now believed to have preceded a thousand year ice age on the North American continent. Read more: Scientists may have solved a huge riddle in Earth’s climate past. It doesn’t bode well for the future. washingtonpost.com/

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 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.

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.

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.

Endocannabinoids, retrograde signaling, and learning.

The endocannabinoid system is involved in our ability to learn. Use of medical marijuana, in quantity, is known to reduce short term memory but it may also be helping the body form long term memories. However our natural endocannabinoid system wouldn’t primarily use the equivalent to the euphoria forming THC called anandamide. That is used to reduce nerve cell signaling. It is the non euphoria causing 2AG that is used within our brains to cause stronger nerve cell signals – practice more and the cells are more active in a certain order and that pathway is strengthened so next the cells will fire in that order more easily. (Endocannabinoids Performance through Retrograde Signaling).

More information about nerve signaling between brain cell synapses see Neuroscience, 6th Edition, pages 85-112, 169-189, and 571-593, (1), or summary information and short video explanations are available online for the previous edition: Synaptic Transmission, Synaptic Plasticity, Modification of Brain Circuits as a Result of Experience.

2AG is more similar to the non-euphoric cannabidiol (CBD) that is found in varying amounts in certain strains of medical marijuana. Both 2AG and CBD can activate both the Cannabinoid Receptor 1 and the Cannabinoid Receptor 2. It can have pain relieving and anxiety relieving benefits. (About the Endocannabinoid System)

Phospholipids and cannabinoids can be found in some legally and commonly available foods in addition to medical marijuana or the non-euphoric hemp kernel or hemp seed oil. See this post for more information about the nutrient group and other important nutrients, our bodies need all or most of them on a daily basis: Macro- and Micro-nutrients: Description and Food Sources.

Happy learning!
