Precarious

As is my usual routine I took my dog Cosmo out for our walk to the mailbox yesterday. Along the way I had a thought about the precariousness of our existence on Earth. We live in this sort of illusion as our daily life is wrapped in an assumption of stability. For the most part our human brains encounter the same environment everyday. Most of us wake up in the morning and are active during the day. The light from our sun scatters in our atmosphere, heating and lighting and otherwise presenting a world around us that seems stable. Somedays are cloudy, others sunny, often a mix of the two. As we go about our days we see a mix of human and non-human species, natural and human environments. We eat and breath, work, play, and talk.

But our life on this planet exists on the thinnest of onion skins. The biosphere of our planet, the zone in which all life happens is remarkably thin. While the actual thickness of the biosphere is not easily measured it generally falls within a range of 6.5 miles. At the highest we have birds flying as high as 1.1 mile and at the depth we have fish 5.2 miles below the water. There are examples of higher flying birds and deeper dwelling organisms but they are exceptions to the general. The diameter of the earth is 7,918 miles. The radius is 3,959 miles. Almost all life on our planet lives on the outer 6.5 miles of that.

As an amateur astronomer I've spent a good bit of time viewing and contemplating space and distance. For all of the beauty of the stars in the night sky, space is mostly empty. The space between stars is vast. The space between galaxies even more so. If we just turn our attention to our own solar system and what exists here well, again, it's mostly empty space. Our Sun makes up 99.86% of the matter in our solar system. Our Earth, though it is the densest planet in the solar system, is only the tiniest proportion of the mass of our solar system. It barely registers. On the scale of our solar system our Earth is merely a tiny point separated from the sun and other planets by vast distances. To get a sense of it watch this amazing video by Wylie Overstreet in which three guys drove out to the desert of Nevada with a to-scale model to demonstrate the spacing of our solar system.

Our lived experience, our world, is just a precarious, thin layer on what amounts to a very tiny planet. On a clear, dark night I can lookup and see several thousand stars with my naked eyes. In remote locations such as mine there is little light pollution and the atmosphere disappears. It is in this star-lit darkness that I can begin to experience the Earth as a space ship of sorts. It really is a living space ship. In our orbit around the sun we move through space at 67,000 miles per hour. But remember, our solar system is also moving around the center of the Milky Way galaxy at 490,000 miles per hour. Of course we don't see it or feel it directly but it is happening nonetheless.

Life on Earth is precarious. It's stability is not permanent. Our sense of day-to-day continuity is something we're used to and something we assume will continue. I'd suggest that if more people had a better sense of how it all works, had a better sense of just how thin the envelope of safety is, perhaps they might be more inclined to take seriously the warning of science regarding climate change, habitat loss and other aspects of biosphere stability. It's too late to stop much of what we've set in motion but if we don't make real change very soon we will experience the worst case scenarios.

It’s up to us

So, Trump won the 2016 election. Yikes. Many are rightly concerned with what he and the Republican controlled congress will do. So many issues, far too many to cover here. No, this is a post about climate change because that’s one that affects us all and it’s the one that in the near and long term is causing significant damage to the ecosystems of our planet to the degree that our very survival is in question. For far, far too long people have looked to government for solutions. To technology and products for easy or even fun fixes. This must stop.

I think the real question is when will we all become the solution for the planet? I understand that laws can help, that federal funding can help. But each and every day every person on the planet makes choices, mostly going with the flow and the flow is harmful. This is especially true in the U.S. and other affluent nations where consumption of energy and goods have been far higher. It’s easier to go with the flow and so we do. We drive. We turn the thermostat to whatever makes us most comfortable. We buy food shipped in from across the country or world. We freeze our food, we refrigerate it. We buy new phones, tablets, and computers, big screen televisions, and huge houses to fill. New cars, new clothes, and the list goes on.

What. Are. We. Waiting. For? Must we really be told by the government how to behave? Forced? I get that corporations need such enforcement. The vast majority of them behave very badly in regards to the environment. But each of us? We can choose to do better. Every day we can choose to harm less but by and large we choose to harm more because its our way of life. Our way of life is based on consumption, comfort and convenience all of which are based on the burning of fossil fuels. That’s it. There’s no magic involved in fixing this.

DO LESS. CONSUME LESS. BE LESS COMFORTABLE. ACCEPT INCONVENIENCE.

A list of the things we can do everyday regardless of who is president:

Do the bare minimum in climate control of your home. If it’s cold outside be as cold inside as you can be. It was 30° today at sunrise. My tiny home was 50° because my heat was off. I was cozy because I was wearing warm clothes and was covered with blankets, a dog and a cat. I got up put on a jacket and made some coffee and oatmeal. In the summer I do the same. I do the best I can to deal with the heat. Eventually I turn on the AC just as this winter I will use heat. But I make a choice to cover up and to wear layers. I don’t assume it’s my right to crank my heat up to 70 or 75 or any other temperature.

Don’t drive unless you must. I work from home so it’s easy. I go to town once a week or less. I only go if I must and when I do I combine all my errands. If I forget something it waits until the next trip. When I lived in Memphis I walked and used a bike as much as possible. I did use a car when I needed to… and sometimes when it was convenient. But that’s when I made the wrong choice. Everyday our highways are full of cars most of which have only one person in them. That’s the wrong choice.

Take a train, not a plane. This is a big one. We fly the globe with little consideration of the climate change impact. If you’ve flown in the past year can you also say how much carbon your flight produced? Was it even on your radar? For some it may be but I’d guess that for most it never enters the equation. Why not? If we must travel we should travel by train as it is FAR more efficient.

Buy less. Buy used. Share. Make do. This is pretty straight forward. You don’t buy stuff unless you must. When you do buy you buy used if you can. Borrow first. Fix first. If you replace something and it is still useable (computers and gadgets especially) make sure it goes somewhere where it will be reused. Whether you sell it or donate it, be responsible for it because it’s not waste. It’s a resource with lots of energy bound up in it.

Reuse and recycle as much as possible. I stopped buying trash bags a long time ago. I use canvas bags for shopping but occasionally get the plastic bags that I use for trash. I throw away one of those plastic shopping bags filled with trash once every 2–3 weeks. Almost everything is recycled. When I do visit the dumpster it is always full of mostly recyclable materials that others are too lazy to recycle. Most “trash” isn’t trash at all.

Eat less meat, eat local food if possible. Food takes energy to produce and transport. Some takes more energy, beef and other raised livestock especially. This one can get complicated and probably requires it’s own post.

Do less in a general way. People are always on the go. Stop. Take a nap. Read a book. Take a walk. Just stay out of your car.

Last but not least, choose not to have children. This is another biggy that probably could do with it’s own post. Each human requires a lifetime of resources. There are 7+billion of us on the planet. We probably need to reduce that by lowering the birth rate.

This is just a partial list that covers some of the most obvious choices that also happen to have the most impact. I’ve had a thought in the past day that it would be great if we had a social media that combined aspects of FB, Instagram, Twitter etc but which was focused on making such changes. A website that offered an opportunity to commit to the most important, impactful choices that individuals can make. Such a site would include ways to share and document solutions and efforts. We should celebrate the effort and the change. Our social media hashtags should be about how we’re saving the planet. Our selfies should show our gardens and our produce. Our latest home improvement share should demonstrate practical repairs, re-uses and re-purposes. I think our use of social media has, to now, largely been about ego and status. That should change. It should be about supporting one another’s efforts to make the changes we must make if we are to survive.

Many of us were surprised by the election of 2016. Many upset. There’s much fear about the policies that will be enacted. The fears are valid. But much of the work we have to do would have existed regardless of the election. Especially in regards to the environment, much of what can happen, much of what needs to happen, much of what must happen, is in our own hands. We cannot wait for government to force us. We cannot wait for convenient technological fixes. We cannot wait. Me and you. We each make our choices. We must make better choices for ourselves and encourage others in our lives to do the same.

Off the Charts Heat

August might be a new record for hottest month ever recorded:

On Monday, the National Aeronautics and Space Administration announced that August 2016 has probably set a new record for the warmest absolute month ever measured, though it’s so close to July 2016 as to be in a statistically indistinguishable tie. That’s saying something, because Earth’s globally averaged temperature normally peaks in July — this year, that didn’t happen. Whichever month is a hair warmer, the conclusion is the same: When it comes to global warming, 2016 is something very special.

Effects of Climate Change Creeping In

The New York Times reports on already occurring climate change flooding of coast:

NORFOLK, Va. — Huge vertical rulers are sprouting beside low spots in the streets here, so people can judge if the tidal floods that increasingly inundate their roads are too deep to drive through.

 

Five hundred miles down the Atlantic Coast, the only road to Tybee Island, Ga., is disappearing beneath the sea several times a year, cutting the town off from the mainland.

 

And another 500 miles on, in Fort Lauderdale, Fla., increased tidal flooding is forcing the city to spend millions fixing battered roads and drains — and, at times, to send out giant vacuum trucks to suck saltwater off the streets.

Yet another example that this is not a problem of the future.

Our Gigaton Future

This is, without a doubt, the best climate change infographic I’ve ever seen. The perfect starting point for a conversation with friends or family that have not taken the time to consider the scope or time frame of the climate change crisis. How Many Gigatons of Carbon Dioxide? You should definitely swing over and check out the site. They give additional infographics as well as source information for this one.

The U.S. Political System is BROKEN

Worried about climate change? Don’t be! The US Senate voted 50-49 to reject “the scientific consensus that humans are causing climate change. So. Problem solved!

The Senate rejected the scientific consensus that humans are causing climate change, days after NASA and the National Oceanic and Atmospheric Administration declared 2014 the hottest year ever recorded on Earth.

Fools. No. Criminals.

Apple and the environment

Apple’s new solar farm and other environmental efforts:(null)

Apple’s been on a very impressive roll and I’m not talking about it’s ever evolving line of mobile devices and computers, but rather its continuing build-out of solar farms. In 2012 they completed their Maiden North Carolin data center with its own on-site solar power facility which is the largest privately owned solar array in the U.S. Since then they’ve completed work on a facility in Prineville Oregon that utilizes “micro-hydro” and another solar facility in Reno Nevada is set to come online in 2015. In locations where they do not generate power they are sourcing it from wind and other renewables.

National Climate Assessment for Agriculture

National Climate Assessment for Agriculture:

Climate disruptions to agriculture have increased. Many regions will experience declines in crop and livestock production from increased stress due to weeds, diseases, insect pests, and other climate change induced stresses.

The United States produces nearly $330 billion per year in agricultural commodities, with contributions from livestock accounting for roughly half of that value (Figure 6.1). Production of all commodities will be vulnerable to direct impacts (from changes in crop and livestock development and yield due to changing climate conditions and extreme weather events) and indirect impacts (through increasing pressures from pests and pathogens that will benefit from a changing climate). The agricultural sector continually adapts to climate change through changes in crop rotations, planting times, genetic selection, fertilizer management, pest management, water management, and shifts in areas of crop production. These have proven to be effective strategies to allow previous agricultural production to increase, as evidenced by the continued growth in production and efficiency across the United States.

Climate change poses a major challenge to U.S. agriculture because of the critical dependence of the agricultural system on climate and because of the complex role agriculture plays in rural and national social and economic systems (Figure 6.2). Climate change has the potential to both positively and negatively affect the location, timing, and productivity of crop, livestock, and fishery systems at local, national, and global scales. It will also alter the stability of food supplies and create new food security challenges for the United States as the world seeks to feed nine billion people by 2050. U.S. agriculture exists as part of the global economy and agricultural exports have outpaced imports as part of the overall balance of trade. However, climate change will affect the quantity of produce available for export and import as well as prices (Figure 6.3).

National Climate Assessment

A very nicely done website though it is a shame so little has been done to make real world changes: National Climate Assessment. Not that educating the public isn’t important. It certainly is. But far too little is happening in the way of real and drastic changes.

From the page:

U.S. average temperature has increased by 1.3°F to 1.9°F since record keeping began in 1895; most of this increase has occurred since about 1970. The most recent decade was the nation’s warmest on record. Temperatures in the United States are expected to continue to rise. Because human-induced warming is superimposed on a naturally varying climate, the temperature rise has not been, and will not be, uniform or smooth across the country or over time.
