How I eliminated junk mail

Several years ago, I decided to tackle my junk mail issue. My mailbox was filled with catalogs and other junk mail every day and I realize this amounted to an enormous amount of waste despite the fact that I recycled everything.   The idea of cutting down trees, printing catalogs and mailing them to a recipient who immediately disposes of them is the epitome of an unsustainable reality and I wanted no part of it.

I took several approaches to eliminating junk mail.   First, I subscribed to the TrustedID - one of several direct mail preference services and entered my preferences on their website.  This organization effectively handles the rest for you, here is what they say on their webpage:
We act on your behalf to protect your consumer rights and get your opt-outs processed. You can keep track of your opt-outs, and if you receive the mail again, we will follow up. We work with over 8,000 companies — and the largest data brokers — to honor your choices and protect your privacy. We have processed over 25 million opt-outs by over 1.7 million account holders. 

The direct mail industry also offers another option known as the National Do Not Mail List.  Both are good examples of an industry policing themselves in order to reduce their own costs.   Here is how they explain their service:
As direct marketers ourselves, we know that mail-order companies don't want to waste their money sending mail to people who don't want to receive it.

They'll gladly take your name off their lists when they're asked to do so. But with countless mail-order companies doing business today, you just can't contact enough of them on your own to make a difference. The postage alone would cost a fortune!

A similar option is available from DMAchoice.org  which also offers an option for reducing junk email.

Incidentally, if you have not already signed up with the National Do Not Call Registry - a service of the Federal Trade Commission, you can reduce the number of telemarketing phone calls that way.  I have signed up for that service, but still get solicitation phone calls.  The way to eliminate these is to refer to their caller ID and call them back, many of them offer an option of "press 1 to be removed from our calling list", and if not some of them will connect to an actual person who will remove you from their list if you ask nicely.  I feel that is important to be polite when asking to be removed - the person you are talking to is not the bad guy here, just an employee.

Finally, when all else fails I made a simple rubber stamp that prints the following:

please remove
from your mailing list
thanks

Of course you can also write this on their subscription form. This is particularly useful when they provide you with a postage free return envelope.  All I do is remove the return section, stamp it next to my address and stick it in their envelope.  They get the message eventually!

I also reduce mail in general by paying all my bills electronically either through direct debit or paying through the company's web portal. 

At this point I can honestly say that I rarely get any junk mail whatsoever.  I still do get a few catalogs and mailings from companies I do business with.

According to another junk mail reducing web site: www.41pounds.org: "The average adult receives 41 pounds of junk mail each year of which 44% goes to the landfill unopened" (or hopefully it is recycled).  They have more statistics that make the idea of reducing this waste very compelling.  They have a $35.00 one-time fee and use $10 to support effective non-profits like Habitat for Humanity.

If more of us took this simple action, we could have a significant impact.

On a slightly different topic, I have also subscribed to Incogni - a service that removes all of your personal information from the Internet.  From their website:
Data brokers collect your personal information and profit off it at the expense of your privacy. Let Incogni help you take back control of your data, reduce spam, and prevent scam attacks by opting you out of their databases automatically.
A one month or two months subscription should take care of everything, just be sure to cancel your subscription after two months.  After this it is largely unnecessary.

Conserving water with a circulation pump

Like many houses, our master bathroom is at the far end of the house from the water heater.  A total of about 45 feet of copper pipe that must be heated before hot water arrives at the faucet.  This takes from 80 seconds in the summer to over 2 minutes in the winter, and wastes a lot of water and energy used to heat it.  When I learned about a clever pump made by ACT, Inc., I decided to install it right away.

The principle is that a pump is installed under the sink that pulls hot water up to the pump, and returns it back down the cold water pipe to the water heater at the press of a button.  The 54 Watt pump shuts off as soon as sufficiently hot water is present.  Each time you need hot water you just press a button and wait half a minute while the water is sent back to the water heater tank instead of down the drain.  The pump shuts off at a pre-set temperature.

 

This system differs from other designs that constantly circulate hot water through the plumbing to keep it available at all the faucets constantly.  I don't  recommend that type of system as it actually wastes energy, both at the pump and due to radiated heat loss from the plumbing which acts as a defacto radiator in the walls of your house.
The D'Mand system reduces waste and saves energy in 3 ways:

• reduces the use of our 1500 Watt 240Volt  well pump.
• reduces the need to heat water that would just go to waste down the drain.
• reduces waste water entering our septic system.

The only drawback is that the pump requires electricity under the sink, which requires wiring in a new (GFCI protected) outlet in most cases.  The basic pump and controls sell for about $400, plus some plumbing parts.  So the installed parts cost was around $500.

The installation of the pump is quite simple.  After shutting off the water supply and draining the lines to the sink, the faucet shut offs are removed.  A tee is inserted, and the shut-off is replaced.  Then the 2 flexible lines to the pump are installed onto the new tee thread.  This took me about 20 minutes.

I am an experienced plumber so I had no trouble installing the pump.  Any plumber would also find this a simple installation.

The challenging part is that an electric outlet is required under the sink.  The nearest outlet in our bathroom is off to the right.  So I made a run to the hardware store to get a bunch of Wiremold (surface wiring conduit) parts.  Then I added a breakout box on top of the existing outlet and ran Wiremold channel across and down into the space under the sink where I installed a new outlet for the pump.  This part took over 3 hours!

 
I also made an attractive circular white acrylic switch plate, and used a stainless steel push button.

Once the button is pressed the pump turns on immediately and shuts off automatically as soon as it senses hot water at the pump.  This saves several gallons of water that would otherwise run down the drain, and reduces the usage of our tankless water heater.  In our home the cold line returns to the bottom our solar storage tank where the sun heats it up for free.

Before the pump was installed it would take 80 seconds for the hot water to arrive, now the pump brings it up in about 50 seconds after pressing the button, and the water runs hot from the faucet within a few seconds.  They also make a motion sensor that will turn the pump on automatically when you enter the bathroom (or kitchen).  Here is the accessories page.

This system is relatively expensive and I don't expect a payback any time soon.  This is something I did as part of my commitment to living sustainably using technology.  I admit it may not be for everyone.

Reviewing our renewable energy and efficiency investments.

Since my ex-wife and I purchased our home in Maine in 2001 I have been working at reducing our energy footprint as part of my commitment to live as sustainably as practical.  My strategy has been to reduce use of fossil fuel by improving things like building insulation and increasing efficiency in general. But also I have added renewable energy sources such as a solar heating system for the hot water in our home and the 5.8 kW solar array I installed, and the solar augmented heating system for my workshop.  I decided to review my progress so far since I have extensive data on all of our energy sources and costs.  This information is derived mostly from our utility bills.


We use propane to heat the house and also for cooking, clothes drying, and water heating.  The chart below shows our annualized usage and cost for propane per heating season.  As you can see we have reduced our use of propane by about 50% over the years.  The biggest impact was the solar water heating system installed in 2006.

Not factored into our relatively low propane costs is the fact that we burn up to 2 cords of firewood per year at a cost ranging from $300-$500 per year. In 2014 we spent $425 for firewood which brings our recent total heating cost to a little over $1400 which is less than half the Maine state average for home heating costs. 

Some of the things responsible for our diminishing usage are:

• Improved basement insulation added to exterior concrete walls.
• Tightening up the building envelope by foam insulating air gaps around window and door framing.
• Adding interior storm window panels and closing honeycomb insulating shades in the cold winter nights.
• Weatherstripping around exterior doors and improving attic insulation.

I built a solar augmented heating system for my super insulated 1260 sq.ft.workshop in 2001.  Since then I have reduced the use of propane to heat the building by 75% by lowering the thermostats and transitioning to burning (renewable) firewood that I mostly cut from my own 2.5 acre lot. 

Thanks to the solar power system I installed, our average electric bill would be around $10 if we did not have the Chevy Volt electric vehicle which adds approximately $45 per month to our monthly bill.

The $45 average monthly electric cost to charge the Chevy Volt is reducing our gasoline usage by about 26 gallons for that vehicle since we drive in electric mode about 60% of the time.  (The remaining 40% are driven in “range extender” mode at approximately 40 mpg.)  And since a large percentage of the charging power for the Volt comes from our solar array in the summer, we are driving for largely free and carbon neutral during those months.

One can look at all of the investments I have made in reducing our energy footprint in terms of return on investment. In actual dollars most of these investments have already paid for themselves, such as the solar hot water heating system I installed in 2006 which according to my calculations paid for itself in approximately 4.5 years and will save us an estimated $11,000 over 25 years:

 

In general investing in renewable energy yields a better return than investing in the stock market. Even my relatively expensive solar power installation that has cost me over $25,000 will pay for itself within 16 or 18 years (accounting for federal and state incentives) assuming it had been financed at below 5% interest.  Since I have already paid off that system, the energy savings is all pure profit at this point.

Garbage and recycling

My small town in rural Maine has a population of less than 3000 people and a few years ago we instituted a zero sort recycling pickup.  Prior to that all recycling had to be sorted and taken to a series of containers at the town office and only a few stalwart citizens made use of this system which was cumbersome.  It was particularly challenging during the heavy Maine winters.  Now we put out a single bin of mixed recyclables every two weeks, while our regular trash is picked up weekly.  Residents have been slow to commit to the recycling plan and in 2014 the numbers were not very encouraging.  922.8 tons were sent to either landfill or waste to energy facilities, while only 217.5 tons of recyclables were sent to a sort facility.  While we are charged for garbage and recycling pickup, there is no tipping fee (based on tonnage) for the recyclable pickup.  So you would think the town residents would see the incentive to recycle since it would reduce our local property taxes.

Being someone who is very committed to sustainability, my waste and recycling stream is minimal but I decided to measure my garbage and recycling output to see how well I am doing.  Before I take the bins to the curb I weigh them and subtract the weight of the container to get the net weight and enter it into a spreadsheet from which I can extract this chart:

chart will be updated weekly throughout the year

Not documented are redeemable cans and bottles (we get 5 cents each in Maine), but this amounts to only a few ounces a week.  Also I pick up roadside trash around my neighborhood in a 1/2 mile radius and that adds a pound or so a week of recyclables, redeemables and trash.

Throughout the winter my I recycle less paper and cardboard because I use those materials as kindling for my 2 wood stoves, so my numbers are a bit low to start with.  Most of what ends up in the garbage is food packaging and some office waste. 

Occasionally I dispose of some broken piece of equipment, but I usually strip out any parts that I can use before it goes in the garbage.  Larger electronic devices such as computer printers are taken to the local electronics store to be recycled rather than trashed.  And rechargeable batteries and old CF lamps go to the local drop-off bins in Lowe's hardware store.  Bulky thinks like old appliances or furniture are delivered to the land fill - but this happens very rarely.

I am pleased to see that I am averaging around 60-70% recycling to 30-40% trash.  Given the very small amount of actual materials I dispose of, all it will take is one large heavy item to skew the statistics.  So it will be interesting to see how I average out at the end of the year.For reference the EPA says an average American: "...recycled and composted 1.51 pounds of our individual waste generation of 4.38 pounds per person per day."  My weekly average so far is about 1/3 of that.  I do see a few neighbors that put out three or four garbage pails per week and very little in their recycling bins and it is hard for me to understand how a family can create that much garbage.  Our local landfill was supposed to have been closed a year or two ago but they somehow found more room to keep building a mountain of garbage there.  Maine is slowly moving toward a more sustainable waste stream with a number of waste to energy plants and biomass to energy plants for organic waste. 

The thing about garbage is once it leaves the curb most people do not think about it whereas I personally have visited both the local garbage dump and the recycling sorting facility that processes our recycling.  Both places are quite amazing.  The technology for sorting recyclables is so efficient that less than 1% comes out at the other end as garbage and this is mostly due to people putting things into the recycling bins that don't belong there due to ignorance or laziness.  

Zero sort recycling plant separating materials

Recycling plants operate at a profit and every month bidders show up to make offers on the spot market for all of the recycled materials.  One thing I learned from a tour of the plant was that all of the glass gets crushed into a single pile of mixed brown, green, and clear.  This is sold to the nearby Coors bottling plant because the average net color is quite close to the light brown color that they use for their bottles.  Here is an excellent video showing how the materials are sorted at the plant that processes our recyclables.

Here is my chart from 2015, the numbers are a little higher until October when my ex-wife moved out:

Solar panel seasonal tracking

My workshop with solar arrays

A couple of years ago after I had installed my west facing solar array, I realized there was still some space above my south facing solar collectors that are used to heat the building.  So I decided to install two additional 245W panels.  Each panel feeds an Enphase microinverter that converts the DC solar power to 240VAC that feeds into the main breaker panel.

Solar panels perform optimally when they are pointed directly at the sun and their energy output drops significantly when they are off by as much as 20°.   Since the sun elevation changes from 42° in the winter to 66° in the summer here in Maine (a change of 42°) I felt it would be wise to engineer the panels to track the seasonal changes.

I researched DC linear actuators and found one that had a 24 inch stroke, this means that it could change length from 28 inches to 52 inches.  This would allow me to lower the panel to meet the lowest sun angle in the winter and raise it relatively close to the 66° summer elevation angle.  I am more concerned with optimizing winter power since the days are so much shorter.

Progressive Automations PA-14

I used Google SketchUp to optimize the geometry of the installation.

In order to get the panels to accurately track the sun's position, I designed a servo control system (here is my schematic) and connected it to a timer that activates the electronics several times a day for a minute.  Here is a photo showing the timer mounted above my handmade control panel that allows me to operate it in automatic or manual modes.

Moving the panels in manual override

I designed a solar tracking sensor and built it into a small red plastic dome.  There are two small photocells mounted above and below a black painted metal divider.  When the sun shines unequally on the two sensors a signal is sent to my controller to move the motor until the brightness is equal on both sensors.

Sun tracking sensor with 2 photocells

It is early March now and the actuators are approaching their maximum extension in order to catch the higher angle of the sun.  Due to limitations of the length of throw of the actuators, they only actively track the sun from the fall solstice through the winter until the spring solstice.  This improves performance during the shortest solar days in the year.

Solar panels with linear actuators extended part way

To be honest, I am not sure how much more energy I am gaining by tracking the seasonal solar elevation changes, but it was a lot of fun to engineer this project.  I am reminded that this system is working because the linear actuators are loud enough that I can hear them when they move.  The timer is programmed to activate the system at noon and 2:00pm for a minute every day.

Adventures in EV charging

2012 Chevy Volt

When I purchased my 2012 Chevy Volt, I was aware that it came with its own charging cable that could plug into any regular 120 V outlet, but it would take almost 9 hours to fully charge the vehicle.  Faster Level II chargers could reduce the full charge time to below 4 hours.

Since I wanted to track energy usage for charging the vehicle, I pulled some heavy wire (Romex 10/3) from a 20Amp 240V breaker out to the front of the building and installed a separate Watt meter that I found on eBay, and installed a 120V outlet below it to start with.  (I read the meter weekly and post results to a chart on my web page.)

Me installing Watt meter

With an EV range of 27 to 38 miles, I thought it would be convenient to install a 240V Level II charging station that could charge the vehicle in less than four hours so that I could make several long trips in a single day if needed.  In doing my research I found that most charging stations available sold for over $1000 and up into the several thousands not including installation.  But I found that GM was subsidizing a charging station made by Bosch called the Voltec SPX, and I purchased one for around $500.  Being an electrical engineer and DIY inclined, I installed the charging station myself.  I have learned that if you hire a contractor to do this it can cost anywhere from $300 to almost $2000 depending on how much wire they need to pull for this job.  

The installation was relatively simple:

Voltec SPX charging station and Watt meter

At the time I considered this charging station to be a piece of competent German engineering with a good balance of form and function.  The round shape allows you to hang the coiled charging cord onto it for storage and it appeared to work just fine.

The trouble began 11 months later just before the charging station went out of warranty.  It stopped working and showed a red indicator light.  So I returned it to Bosch and they sent a replacement.  When it failed again a few weeks later I decided to open it up and have a look inside.   What I found was that the engineer who had designed this charging station had installed fuses on the circuit board that were soldered into the board making them completely un-replaceable to your average consumer.  However, as an electrical engineer it was relatively simple for me to remove and replace those blown 15 amp fuses with ones rated for 20A.  The original fuses were rather conservatively rated since the Chevy Volt draws just below 15A per leg of the 240V line.   In retrospect I think that my 240V table saw creates power surges that more than likely caused these fuses to blow.   Here is a close-up of the circuit board inside the charging station:

Fuses in Voltec SPX charging station

I became quite irritated when my replacement fuses blew a few weeks later since it is a pain to open up the charger.  So I installed 2 small 20A circuit breakers on pigtails and sited them where I could reset them from the outside:

2 - 20A circuit breakers added to Voltec SPX charging station

This fix worked, and I was able to re-set the breakers every so often when they tripped.  But a few weeks ago the charger stopped working and displayed an ominous blinking red idiot light.  This time I had had it!  So I went back to charging from a 120V outlet using the Volt charger that came with the vehicle while I researched affordable options. 

Chevy Volt charger

What I found was an affordable open source EV charging station made by Electric Motor Werks Inc. in California.  These guys had developed their product with a Kickstarter campaign in July 2013 and now had a well-designed product on the market that I was able to purchase for under $500.  This clever design is based on the popular Arduino microcontroller and it contains a very basic 240V relay for transferring power to the vehicle.  It is built into a plain-vanilla sealed metal box that can be mounted indoors or outdoors.

I decided to install the charger inside and reuse the charger cable and plug from the original charging station.  Here it is installed inside behind the Watt meter:

JuiceBox charging station

I installed a small green light on the side of the box so I could tell when the charging station was providing power to my vehicle at a glance.

In addition to reusing the original coiled charging cord and plug, I also took the plug holder out of the old charging station and mounted it to the wall under my carport.  This allows me to charge and store the connector in 2 locations which is convenient.

Charge plug holder

This new setup works perfectly and I am pleased to own a piece of open source hardware that I know that I can fix or upgrade myself in the future should it be necessary.  I did require some tech support via email during the installation, and found the guys at Electric Motor Werks Inc. to be very responsive, friendly and helpful.

Here is my Volt being charged under the carport, and you can see the other charge plug storage location below and to the right of the Watt meter out front where I often charge the vehicle in good weather.  I also put a 120V outlet on the left of the meter box for the Volt Charger.

Volt charging from JuiceBox (hidden inside building)

I hate to throw things in the garbage, so I am stripping out all of the parts that I can salvage from the original Voltec charging station including the circuit breakers I added, terminal strips, ribbon cable and even some screws.

Voltec SPX inside - mostly scrap.

Oh, did I mention that my Volt is charged from our 5.6kW solar array?  This means I am driving for free with zero carbon emissions for local driving most of the year.  More info can be found on my Chevy Volt web page.

Geeking out on thermal imaging

June 2017 update: I upgraded to the FLIR One thermal camera that plugs into my smart phone. Much better and less expensive!  http://mistersustainable.blogspot.com/2017/06/solving-mysteries-with-my-new-ir-vision.html

I am a geek and proud of it!  I enjoy using instruments to quantify physical properties and have an arsenal of electronic instruments ranging from voltmeters and oscilloscopes to data loggers, a tachometer, decibel meter, Geiger counter, light meter and Gauss meters and many more.  The most recent addition to my tool belt is a VT04 Visual IR Thermometer made by Fluke.

Fluke VT04 Visual IR Thermometer

This tool is a fraction of the cost of a thermal infrared camera at under $500 and has many features that I find more useful than the Flir brand of IR cameras.  The one feature I find most compelling is that this clever camera incorporates both an infrared imager and a regular camera and it allows you to blend those two images in various ratios.  Here is an example of the dining room windows with three different percentages of infrared overlay:

While the infrared overlay is not very high resolution, and shows as somewhat blurry compared to the professional cameras, it is perfectly sufficient for identifying cold spots inside buildings.  The temperature shown is taken from the center of the image.

The temperatures here in Maine are below 0°F outside tonight, so I used my new tool to study the exterior walls of our home from the inside looking for cold areas that indicate missing or poor insulation.

One of the first things that I suggest that people do when they start out to tighten up the heat leaks in their home is to install outlet covers to prevent cold air leaking in through the outlets in outside walls.  This is a quick inexpensive fix that can have a big effect. Here is a good example showing a normal image of an outlet with an electroluminescent nightlight blocking one outlet:

As you can see the uncovered outlet is leaking cold air and if it were covered with a plastic outlet cover this would reduce the cold air infiltration.  You can buy inexpensive kits that include gaskets and plugs to seal up these leaks.  Here's a how-to about insulating outlets.  I had already installed a foam gasket behind this outlet plate, so there is no cold air leaking around the edges, but I need to buy some more plastic plug-in covers for the actual outlets like this:

The coldest rooms in the house are the bathrooms and laundry room on the west wall. Here is a shot taken of the laundry room wall and ceiling.  The cold area indicates poor or missing insulation, and now I know exactly what needs attending to.  I will be looking into the crawl space above that part of the ceiling real soon!

Most houses do not have any insulation covering the rim joists between floors, and this may be part of the issue here.

The software that comes with the camera allows you to adjust the blend of normal vs IR after the images have been taken which can be very helpful in identifying what was in the shot.  Another feature is the ability to take time-lapse sequences automatically.  And you can set a temperature threshold so that the camera will automatically take a picture when it is exceeded.  Both are features that I have plans to use in the future.

The Fluke VT04 will see a lot of use as I work to identify heat losses and repair them!  It will also come in handy in my electronic design work so I can track overheating components.

Snow throwing

For those of you who like to read vicariously about my life in the frigid Northeast, I thought I would share what is involved in using a snow thrower.  The recent snowstorm was relatively light, but it blew some massive snowdrifts that were over 18 inches deep across our driveway that I had cleared previously.

Gearing up to go out and use the snow thrower makes me think of putting on a spacesuit.  I pull yellow waterproof slickers over my fleece lined jeansI, then put on full-length rubber boots with heavy cotton athletic hiking socks under and pull the slickers down over the boots.  Then a full-length Thinsulite insulated jacket is zipped up all the way to my chin.  Under the jacket I wear just a T-shirt and a plaid flannel shirt, any more than that and I would sweat too much and sweating is a bad idea in frigid temperatures because it makes you feel a lot colder.  I wear very thick Thinsulite insulated gloves with good rubber grips on them.  On my head I have a padded wool hat, and hearing protection that also serves to warm my ears.  (The snow thrower is quite loud).

I use a 5 hp craftsman snow thrower that incorporates all of the basic controls

There are 5 forward speeds, and 2 reverse speeds that are selected by a big lever.

a crank handle allows me to rotate the chute to direct the snow left and right.

 

The top end of the chute can be tilted to direct the snow further or closer to the thrower.

Squeezing the left handle clutches in the auger that sucks the snow into the impeller.

Squeezing the right handle engages the drive clutch.

  

 

Starting a snow thrower is just like starting a gasoline lawnmower.  I set the throttle to full speed, pump a little gas into the carburetor and then pull start it.  I also have the option of using an extension cord to start it electrically which can be convenient sometimes.  Like a lawnmower (or tractor) the engine runs at a constant rate set with a throttle lever, and you set a gear that is appropriate for the snow depth.  Drop it into gear and off we go!

On a day like today, the temperatures barely got up to 15°F with wind blowing at an average of 20 mph and wind chills down around 0°F in the gusts.  There are times where the fine snow blows back onto my face and freezes into my beard mixing with snotcicles from my running nose. 

There is a lot of strategy involved in planning where to throw the snow.  If you throw snow upwind it will just blow back in your face, and that is not only unpleasant but ineffective.   So every pass I have to adjust various aspects of the thrower to put the snow where I want it to go by turning the chute and selecting the appropriate gear and tilt angle for the chute.  For instance if there are only a few inches of snow on the ground I can cruise along in third or fourth gear.  But when the snow is at or above the height of the hopper, I slow to a crawl in first gear leaving the auger running and stopping and starting forward momentum using the right hand clutch handle.  I can hear the engine straining when it is chewing down on too much snow and that is a sign to either drop to a lower gear or pause to let the thrower catch up and chew through the snow in its hopper.

It takes me anywhere between one and two hours to clear our property depending on how much snow has landed.  I need to clear our driveway which is relatively small, but also a path between the house and my workshop.  Another path around to the back of the house so we can get to the woodpile from the rear basement door.  And another path around my workshop to make it easier to access my woodpile, and to clean snow off my collectors and solar panels.  All in all this amounts to hundreds of feet and tons of snow that need to be moved.

I have to admit that it is quite a bit of fun as this is the closest I will get to using heavy earth moving equipment.   Almost every boy/man idealizes having a job using big earth moving equipment I think.   For those of you in southern climates, I hope you have enjoyed this vicarious ride along with me and my snow thrower.

One of the impacts of climate change is an increase in the number of severe precipitation events.  

The jet stream is being severely affected by changes in the Arctic.  The result is that there is an "Atlantic conveyor" that draws moisture from the Gulf of Mexico and blows it up along the East Coast.  For the last several weeks, we have had a series of heavy snowstorms arriving a few days apart.   Any one of these storms by itself would not be an anomaly, but this consistent sequence of heavy storms is a clear indication of climate change. 

Cli-Fi and climate awareness

I have been reading science fiction since I was a kid in the 1960s.  Currently, I read two or three SF books every month on my Kindle and sometimes go back and re-read books that I had read in print years ago.  I particularly enjoy science fiction that takes an existing facet of our world or culture and extrapolates it into the future.  Some SF authors work in the new genre known as "climate fiction" (or Cli-Fi) in which the story focuses on climate change in the near future.

Several years ago I read Kim Stanley Robinson's science in the Capital trilogy that focus on abrupt climate change set in the present day.  Kim is one of Science Fiction's best authors and also one of my personal favorites.  His books tend to be long and wordy and filled with relevant and apparently well researched science, while his characters remain engaging throughout.  Beginning with "Fourty Signs of Rain", this trilogy left a profound impact on me and permanently changed the way I see the world.  Since then I have studied climatology and climate change and have come to believe that what he has portrayed in these books is quite likely to occur this century. 

If you enjoy reading fiction, or science fiction as a way to gain insights into our contemporary culture as I do, you will find these books a good read.  

I recently read John Barnes book "Mother of Storms" which sets a much more dramatic scenario in some ways than Robinson's books.  John is one of Science Fiction's "killer B's" that include other great authors such as Greg Benford, David Brin and Greg Bear - all favorites of mine.  The abrupt climate change scenario in this book is based on cutting-edge science and proposes the idea that enormous methane releases from clathrates buried under the Arctic could trigger a jump in global temperature which in turn could create massive hurricanes on a scale never seen before.  Given that this book was first published in July 1994 (I read a re-print from 2102), it reads as amazingly prescient even today given what we know about the methane trapped under the oceans in the Arctic.  This is known as the methane gun hypothesis in climate studies and is an issue of grave concern to climate scientists as a potential trigger for extremely abrupt climate change.  We are already beginning to see the impacts of increased ocean and air temperatures on moisture uptake into the atmosphere in the form of increasing numbers of severe rain and snowfall events.

Barnes's book follows several intriguing characters through the mayhem that ensues as a giant hurricane and its spawn devastates much of the planet.  This is no made-for-TV style novel, but one grounded deeply in reality and science.  The only thing I found uncomfortable was his penchant for portraying sexual deviance and torture, along with horrifying ways to die.  This is no book for the faint of heart, and portrays a dystopian future humanity.  Nonetheless it is a vivid and engaging read that puts the potential for abrupt climate change into a clear context of a near future human world scenario.

I am currently reading Kim Stanley Robinson's book "2312".  As the title would suggest it is set in the future long after the Earth has been impacted by climate change.  Humanity has become interplanetary and inhabits most of the moons and planets in the solar system.  His characters are deeply engaging and the story is rich and filled with wonderful science fiction technology insights and obscure cultural references.  This is yet another book which indirectly addresses climate change as a possible future for humanity and I highly recommend it as a good read even though I'm only about one third of the way through the book.

If you enjoy reading fiction, or science fiction and want to learn more about climate change, these books create an entertaining and yet factually based way of absorbing knowledge about this crisis that humanity will certainly be confronting in the foreseeable future.

Bye-bye beaches

Frenchman's Bay, Maine - looking northeast

Do you have a favorite ocean beach?  Well pretty soon it will be a memory only.

My extended family has a cabin on Frenchman’s Bay in “Downeast Maine”.  It is a stone’s throw from the beach with a spectacular view of the bay.  In the center of the image below is Mt. Cadillac (the hill in the center) which is the easternmost point of the continental United States where the sun first strikes the continent.

This is my sanctuary, the place where I go to rejuvenate and shut out the world for a while.  As beaches go it is not exactly your tropical island paradise, but the rocks are endlessly interesting and the tide moves so quickly you can actually watch it as it changes over 10 feet two times per day.  Watching the tide rising inexorably is a portent of things to come.

I am sharing this as a reminder to everyone who has a favorite beach somewhere in the world that most of these beaches will be permanently underwater before the end of the century.

Climatologists estimates of how high the ocean level will rise by 2100 continue to escalate, at present they are saying 6 to 13 feet but I suspect it may be more by the time they factor in all of the other feedbacks.  Take a moment to fully process this concept - the beaches will be gone, period.  This means that within your lifetime you will lose what cherished memories you have because we have so thoroughly screwed up the planet that the oceans will inevitably rise and take away many of our favorite places.

If this is not enough of a wake-up call, I do not know what is.
