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.

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:

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.

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.

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.

Climate change is a 100,000 year change

The buildup of greenhouse gases will take hundreds (link)  to possibly hundreds of thousands of years (link) to breakdown and return the atmosphere to levels that we have been used to during our years on earth as human civilizations. The climate changes are also likely to affect the oceans for hundreds of thousands of years. (link) The graph of the increase in the main greenhouse gases is fairly level and then exponentially increases in the recent past: The Big Picture Breakdown of Greenhouse Gases.

Passive Energy Buildings – building for a future with temperature extremes

Passive Energy Building, links for more information 

Climate change is not just about increased temperatures on a global average it is about increased extremes in temperature and increased risk of severe weather conditions. Architecture in many areas is not suited to extreme changes in outdoor temperatures and often glass is a major building material for aesthetic reasons. Glass walls and large windows can make buildings overly cold during cold weather and overly warm during hot sunny conditions. Passive energy architecture tends to use smaller windows that can be shaded during warm conditions and walls may be made of wider materials that provide better insulation during hot or cold weather. 

There is no question of the reality – human use of fossil fuels has been warming the atmosphere since the Industrial Revolution started over one hundred years ago. The ozone layer depletion was addressed successfully with more study and political bipartisan work in the 1970’s and 80’s. Increased use of solar power was also begun at that time but who to blame and loss of fossil fuel profits became more of a concern and disinformation and denial took place after the initial progress with reducing ozone depletion. The history in a long read is available, the introduction and epilogue discuss the current situation and possible directions we are headed as a species and planet inhabitants. “Losing Earth: The Decade We Almost Stopped Climate Change,” by Nathaniel Rich, The New York Times Magazine, August 2, 2018, (Losing Earth/NYTMagazine).

Summary points from the introduction: 

  • Limiting warming to two degrees: tropical reefs will become extinct, sea levels will rise several meters and we will lose the Persian Gulf. This “long term disaster” has become the best case scenario we can hope for if we manage to stop producing greenhouse gases.
  • Three degree warming, possibly the realistic minimum we can expect: “short-term disaster” – loss of forests in the Arctic and loss of most coast cities.
  • Four degree warming: permanent drought in Europe; desertification of large areas of China, India and Bangladesh; Polynesia covered by sea waters; Colorado River reduced to a tiny creek; American Southwest largely uninhabitable.
  • Five degree warming: some leading climate scientist’s consider this level to place human civilization at risk of survival.

Summary take home point – we need to change our civilization in revolutionary ways now – and invent ways to remove greenhouse gases from the air in addition to decreasing adding more to the atmosphere. We need to stop using modern agricultural methods that don’t recycle phosphorus and allow it and other chemicals to run-off into groundwater and coastal waters. (Losing Earth/NYTMagazine).

A free course was available that provides more information about climate change effects that are already occurring and strategies that have been found helpful around the globe: From Climate Science to Action, by The World Bank Group,, resources provided for additional reading are included at the end of this post. A course being offered on the site by the University of Michigan can be enrolled in now which begins August 20th: Act on Climate: Steps to Individual, Community, and Political Action,

This is an area of interest for me but not my area of expertise. Preventative health education is my area of expertise and treating a growing population of humans with more effective methods would also be good for planetary health. Toxic medications eventually add to groundwater pollution and medical equipment and supplies is also adding to pollution.

Reducing use of fossil fuels for air conditioning or heating will ultimately help protect against the long term risks of increasing levels of Carbon Dioxide and other greenhouse gases in the atmosphere.
