On a glorious spring Monday I began spading the next garden plot. The soil was too wet to work so I stopped after four feet.
Excessive spring rain not only affects gardeners, farmers are feeling it too. Vegetable growers were either “mud-planting” or not planting at all. Less than half the anticipated corn crop was planted by May 12, according to Iowa Public Radio. It’s only the fifth time in the last 40 years that has happened.
I planted spring onions, Daikon radishes (KN-BRAVO, 49 days) and Rudolf round (24 days) and D’Avignon (21 days) radishes in three in-ground containers.
The apple blooms continue, although when the wind blows it is a snowstorm of petals creating drifts under the trees. This year has been one of the longer blooms I remember. There are so many blossoms it wouldn’t be bad if some of them didn’t pollinate, sparing me the chore of thinning the buds once they form. The good news is after the long growing season, there should be apples.
After my soil blocking shift Farmer Kate have me a guided tour of her farm. I took photos, which can be found on my Instagram account here. She farms about nine acres in large plots. A lot of it is planted and what isn’t remains in cover crops until its time. Although I’ve worked at Wild Woods Farm for a couple of years, this was the first time I saw the entire acreage.
I started a tray of seeds that didn’t germinate well at the greenhouse. Yellow squash and tomatillo seeds did not germinate at all at the greenhouse. The squash looked a bit funny when I planted them, so I’m trying again. I also used up the arugula seeds, and planted a few blocks of okra and pumpkin as an experiment. Like many things in gardening, we experiment and watch the results.
I’m ready for the second wave of planting as soon as the ground dries. Then it will be a mad dash to get everything in. Even though rain holds us back, the season’s not hardly begun so there’s hope of a bountiful year in the garden.
Gardening is one of the most popular activities on the planet. Whether one lives in an apartment, in a single-family home, or on a farm, local food and flower production can be satisfying on multiple levels. A garden can be a source of nourishment, beauty, exercise, learning, and personal satisfaction. Gardening helps us to be sociable because almost everyone grows something or appreciates those who do.
Gardening is also a way of mitigating the effects of the climate crisis.
The Climate Reality Project posteda list of things gardeners can do to act on climate. They are easy to incorporate into a garden’s daily work. Here’s my take on their list.
Reduce or eliminate synthetic fertilizers
A few years ago I began using composted chicken manure to supplement compost from my bins. The resulting vegetables were dramatically better. This is the kind of fertilizer my local food farmer friends use and it is acceptable for certified organic crop production.
We don’t ask a lot of questions about where the chicken manure originates, and maybe we should, but Iowa ranks first in the United States for egg production with 57.5 million laying hens according to the Iowa Poultry Association. With an 18.2:1 chicken to human ratio, chicken manure is an abundant resource.
There are plenty of reasons to be wary of synthetic fertilizers, according to the Climate Reality Project. Chemical runoff from haphazardly applied fertilizer can drain into streams and lakes, making its way to our water supplies. They can disrupt naturally occurring soil ecosystems, and are a temporary solution to a long-term solvable problem.
When it comes to the climate crisis, fertilizer manufacturing is the issue.
“Four to six tons of carbon are typically emitted into the atmosphere per ton of nitrogen manufactured,” according to Dr. David Wolfe, professor of plant and soil ecology in the School of Integrative Plant Science at Cornell University.
Gardeners should be more conservative about nitrogen use in the garden. Using composted chicken manure to improve soil nitrogen levels can produce great results and avoid the greenhouse gas emissions of synthetic fertilizers.
Plant Trees and other perennials
When we built our home in 1993 there were two volunteer trees on our lot, a mulberry which remains in the northeast corner, and another that died and was replaced with a blue spruce grown from a seven inch seedling. In all I planted 17 of 18 trees here, of which 15 remain. We also have three patches of mature lilac bushes.
Atmospheric CO2 Levels
The benefit of planting trees is they remove carbon dioxide from the atmosphere and store it. Because of their long life and size, they store more carbon than other plants. Scientific data shows the impact of trees on our atmosphere. The NOAA Earth System Research Laboratory at Mauna Loa, Hawaii measures carbon dioxide levels in the atmosphere. Last Saturday, the level of atmospheric CO2 rose to 415.25 parts per million, higher than it has been since humans evolved. Click on the chart of monthly CO2 levels and you can see the impact of deciduous trees. While the overall level continues to rise, as the world greens up in spring, CO2 levels predictably, consistently fall. When leaves fall from the trees, CO2 levels rise again. The thing about planting trees is do it once and the focus can turn to other things.
Trees offer cool shade in the summer and protection from winter winds, so a well-placed tree can reduce emissions and energy bills associated with heating and cooling a home. Fruit trees provide an added bonus for gardeners.
Reduce water use
Science explains that the warmer temperatures associated with the climate crisis increase the rate of water evaporation into the atmosphere, drying out some areas and then falling as excess precipitation in others. This can lead to a cycle of water misuse in ever-drier areas, and plant diseases in regions where average annual precipitation is on the rise. In Iowa we have seen all of that, with the record drought of 2012, and severe flooding that got within 100 yards of our home in 2008.
Lawn and garden watering is estimated to account for 30 percent of all residential water use in the U.S., according to the EPA, and that number “can be much higher in drier parts of the country and in more water-intensive landscapes.” And as much as 50 percent of it is lost to evaporation, wind, or runoff. Water conservation is everyone’s business. I’m not sure why anyone would water a lawn, except maybe a golf course. I don’t play golf. It is better to let a lawn survive in varying temperatures and moisture levels. Thus far in Iowa that’s been possible.
I don’t use an irrigation system or sprinkler in my garden. To ensure adequate moisture to sustain plants in seven plots, I use grass clippings as mulch. Often there are not enough clippings so I’ve been experimenting with plastic sheeting for peppers, cucumbers and broccoli. I have successfully re-used the plastic for multiple years. I use a garden hose to water at the base of the plants and do so sparingly.
“Less frequent, deep watering also encourages deeper root growth to areas where the soil stays moist longer,” according to the Cornell Cooperative Extension. “If supplemental water is determined to be necessary at a specific time and location, be sure to use no more than is needed and minimize your use of potable water.”
Focus on soil health
I have gardened non-stop since we moved into a rented duplex after our 1982 marriage. I have gotten better at gardening, but the biggest improvements came after we ceased being renters and bought our own homes, first in Lake County, Indiana, and then in Johnson County, Iowa. Owning our home enabled me to better consider soil health and long-term investing in it.
When we moved here the living layer of top soil had been removed and sold by the developer, leaving a hard, heavy surface devoid of earthworms and other visible life forms. Gardening, by its nature, must address soil health because if there is no life in the soil, fruit and vegetables won’t grow as well. This is the lesson of row crop agriculture where the best soil has eroded and what remains is supplemented with synthetic fertilizers and other inputs to create an artificial environment for plant growth and pest control.
The story of climate change’s impact on soil health is mostly about changing precipitation patterns, according to the Climate Reality Project.
Extreme downpours can lead to runoff and erosion, stripping healthy soil of key nutrients needed to sustain agriculture. On the other end of the spectrum, frequent droughts can kill off the vital living soil ecosystems necessary to grow healthy crops – and of course, plants can’t grow without water either.
What a gardener wants is soil rich in microorganisms that will sustain plant life through drought and heavy rains. After years of work composting and working our garden plots we can see plenty of earthworms. They are the most visible aspect of a rich miniature biome that sequesters carbon and stores water to make irrigation less needed. Healthy soil helps a garden survive short-term drought and heavy rains by sustaining moisture in the ground near plant roots.
Not many gardeners I know use cover crops, but that is an option to increase soil health. Like most, I add compost in the spring before tillage until the bins are empty.
Reduce tillage
Over the years my relationship with gasoline powered tillers has been inconsistent. A low- or no-till approach to gardening can plays a big role in building the soil organic matter. The reason is simple, when you rototill the ground, you break up the soil ecosystem.
“At its most basic, no-till gardening is the practice of growing produce without disturbing the soil through tillage or plowing,” according to the Climate Reality Project. “In addition to locking up more carbon in the soil, this approach dramatically cuts back on fossil-fuel use in gardening. After all, gasoline-powered garden tools are emitters of CO2.”
The best way to say it is I’m in transition regarding tillage. I have always turned over all the soil in a plot with a spade. What varied over time was whether or not I used a tiller. Sometimes a rented or borrowed a large rototiller to do everything at once, sometimes I used a smaller sized tiller inherited from our father-in-law’s estate, and now I break up the soil with a hoe and rake. I’ve been changing my way of thinking.
Last year I made a tomato plot but instead of turning the entire plot over and breaking the clods of soil down with a hoe and rake, I made two-foot lanes for the tomatoes. The production was excellent. Not tilling the entire plot leaves some of the soil structure in place and in the long term, that’s better for soil health.
This is an ongoing experiment, but the obvious conclusion is less tillage is better.
Opt for hand tools
My main garden tools are shovels, a hoe, rakes, a post driver, and a bucket of hand tools. Eliminating use of a rototiller was an important step in reducing emissions and using the spade, hoe and garden rake to break up the soil provides exercise. I also plant crops in four waves: early (kale, broccoli, peas, carrots, beets, radishes), succession planting (spinach, onions, leeks, herbs, beans and celery), tomatoes, and late (cucumbers, zucchini, squash, eggplant and peppers). Spreading planting over weeks helps make the physical labor of using hand tools more tolerable.
With a large garden and yard it proved difficult to make the battery-powered trimmer work: I kept running out of charge. When it broke, I got a new gasoline-powered trimmer. I also use my gasoline-powered mower and a chain saw. I used less than five gallons of gasoline between the lawn mower, chain saw and trimmer this year. Not perfect, but consistent with a practice to reduce the amount of garden emissions.
Part of my strategy of lawn maintenance is to avoid the use of chemicals completely and mow less often, maybe once every three or four weeks. The benefit of this practice is the lawn becomes a habitat for local flora and fauna. The downside is I don’t get enough grass clippings in a season for mulch. After years of the practice, the neighbors haven’t complained.
Conclusion
The climate crisis is real, it is now, and we have to do something about it. The lesson I learned from being a member of the Climate Reality Leadership Corps is there are many way to contribute to solutions in our daily lives. Among the things we do in a day, mitigating the effects of climate change must be one of them. We are all in this together and even a gardener can do something to help.
On a sunny Friday among peak apple blossoms I cleared the fourth plot for a multi-crop gardening area.
The first three plots have early vegetables and are not completely planted. With eight trays of seedlings ready, and more in the greenhouse, it’s time to get them, along with seeds I’ve been holding, in the ground.
I don’t clear garden plots in autumn. I’ve read it’s best to leave them and let small rodents eat the weed seeds left behind. Clearing a plot becomes a bit of a spring production.
I remove the fencing, cages, fence posts and any non-organic debris. Then I gather brush generated since the last burn pile and burn it with straw from the plot. Once the fire dies down I run the mower over it with the deck as low as it will go. Yesterday this produced a 15 by 12 foot plot ready for planning, soil preparation, planting and fencing.
The plan is for spring onions, celery, spinach, lettuce, radishes, leeks, green beans, red beans, chives, arugula, basil, parsley and cilantro. The plan is written, now subject to further consideration and modification as I turn the soil, spade-by-spade and attempt to beat forecast rain.
This work is the core of who I am. I’m thankful to be able to do it.
Monday didn’t happen as expected. There were three things involving arborists, health care and farming.
Without announcement, the arborist arrived to take down a maple tree I planted on the northwest corner of the house. Turns out I didn’t know what I was doing when planting the 12-inch, stick-sized sapling so close to the house in 1994.
Now fully grown, unusually strong winds already took out one of the main branches. We determined it would be less expensive to remove the tree than pay for a roof repair when limbs inevitably blew down on it.
It was a small way of mitigating the damage of the climate crisis.
The crew was four men with two pickup trucks to haul away brush and wood. The benefit of using an arborist instead of a tree service is the equipment is pickup trucks, ladders, and an array of Stihl brand chainsaws and old fashioned loppers. There is minimal soil compaction around the work site without heavy equipment and that’s important to a home owner.
Arborists at Work
The arborists took out the maple and trimmed the pin oak, finishing well before noon. Our next door neighbor engaged them for tree trimming and by the end of the day our corner of the neighborhood was looking good.
Monday’s main event was a trip to the local clinic to get checked out.
Last Friday someone called, saying I was overdue for a physical exam. They had an appointment the following business day, which in a small city is disconcerting. The hospital managing the clinic is already having financial difficulties. The fear is the clinic will close, making it neccessary to drive to the county seat for health care. I took the appointment.
We no longer have two physicians at our clinic as one was replaced with an ARNP or Advanced Registered Nurse Practitioner. I get that the United States is facing a physician shortage, and our ARNP fills a coverage gap. It makes sense to differentiate the skills being performed in a local clinic and find practitioners that closely match them.
I miss what I had for a very long time, a doctor with whom I established a relationship and could get to know in our community. I’m not saying it was great, or that we should go back. I miss it but am ready to move on, seeking an answer to the question how do people get treatment in a scenario in which part of every office visit is talking about how to pay for services?
Arborist at Work
I liked my ARNP. He explained something I hadn’t considered. He said I was scheduled for a physical exam and there would be a significant cost. I explained that’s what the Friday caller said I needed so I went with it. He changed the billing code and said, once a person reaches a certain age, the better course of action when seeking treatment is to come into the clinic for specific maladies, without getting a traditional physical exam. I have a history already, which when combined with age and lifestyle risks, along with my complaints, can determine a course of care without physical examinations as I’ve had previously. What their team did today was little different from what the last physician did, with the exception the prostate examination was delayed until the results of a panel of lab tests he ordered were known.
At 3:40 p.m. I drove to the farm to pick up our vegetable share of Bok Choy and Koji, Leaf Broccoli, Mixed Greens, Lettuce, Spring Garlic, and Garlic Chives. Each year I secure onion starts for our garden leftover once the farm has planted theirs. It was time. Usually I get a bundle or two of starts produced in Texas, but Monday was different. The farmers gave me two trays of locally grown starts still in soil blocks. It seemed a generous gift considering the work that produced them. I was thankful to have them.
A day that started with a headache from a 12-hour fast before my clinic appointment turned out for the better. I had a cup of coffee after the clinic and the day got progressively better. It was one more day of sustaining a life in a turbulent world.
A thin haze dimmed reflected light from the moon. Thin enough to allow dots of starlight to penetrate the atmosphere and with moonlight illuminate the neighborhood.
The haze was just enough to know it was there.
I moved trays of kale, broccoli and parsley seedlings from the garage to a pallet near the driveway in the hazed light of a waxing gibbous moon.
Today is the 50th Earth Day.
Earth Day is less about a view of night’s starry presence than it is about seeing Earth as a whole. Few times in our history has a photo of Earth made such a difference in so many lives as Earthrise taken by astronaut Bill Anders. It sparked the movement that brought us Earth Day which continues to this day.
We humans have not been the best stewards of Earth since April 22, 1970.
Early Years
Vague notions of ascendancy were taught by our grade school teachers. In the seventh grade I was segregated from neighborhood friends to join a college-bound group of peers in a special classroom. I entered the National Honor Society in high school and when I graduated in 1970 had no clue what I wanted to be. I knew I was college bound, not because I wanted that, but because the nuns said I should be. That I finished college at all was miraculous. I felt a sense of relief as President Nixon appeared to heed a shared need to do something about the environment. When he created the Clean Air Act (1970), and then the Clean Water Act (1972) I felt Earth Day had done its job.
Military Service
When I left Iowa in 1976 for basic training at Fort Jackson, S.C. I had little idea of what being a military officer meant. I knew the Vietnam War was over and I wanted to serve as my father had. The context was a paternal grandfather went to prison for draft evasion during World War II. Given a choice, I would serve. Among other things, military service taught me the environmental cost of war.
The environment has long been a silent casualty of war and armed conflict. From the contamination of land and the destruction of forests to the plunder of natural resources and the collapse of management systems, the environmental consequences of war are often widespread and devastating. ~ Ban Ki-moon, UN secretary general
Oil consumption and related carbon emissions are significant contributing factors to degradation of our atmosphere. The use of depleted uranium in military ordnance, notably during the 1991 Gulf War, created a complex array of environmental problems including introduction of carcinogens into the environment. We destroyed Iraqi infrastructure, including water and sewer systems, and contaminated surrounding ecosystems. The use of defoliant Agent Orange in Vietnam created sickness among soldiers and decimated biodiversity in the country’s tropical rain forests. We should include potential use of nuclear weapons which studies have shown, in a limited nuclear war, could create a nuclear winter making 2 billion people food insecure.
Awareness of the military’s environmental problems is a lesson learned.
Worklife
I worked 25 years in the transportation business, including an 18-month stint with Amoco Oil Company in Chicago. What goes almost unnoticed as part of background noise in modern society is the amount of fossil fuels burned by trucking, railroad and ocean-going transport vehicles. When I was maintenance director for a large trucking firm, I spent $25 million per year purchasing diesel fuel for our vehicles. That doesn’t count fuel burned by our affiliate companies which used independent contractors who fueled their own semi-tractor trailers. The fundamental dynamic during this period was I needed a job to support our family and given what I perceived as a lack of opportunity after college and military service I took what I could find, staying there for most of my professional career. I traded the environment for financial security. My main concerns were job performance and getting ahead. The nuns in grade school didn’t adequately prepare me for this kind of worklife. Environmental issues were off the table.
Retirement
When I left transportation ten years ago the climate crisis became more real.
In 2013 I participated in The Climate Reality Project conference in Chicago, taught by former Vice President Al Gore. It made a difference to learn the science of climate change and in the following months I began presenting the information learned in public speaking, in letters and articles in the newspaper and in my daily life.
We entered a period of politicization of everything. Facts ceased to matter. Income inequality worsened and the U.S. government seemed owned by the richest people. The scientific facts about climate change became a political choice: do you or don’t you believe the science of climate change?
Climate change is real and is impacting our lives now. Even banks are seeing how it can impact their business. From an open letter from the Governor of Bank of England Mark Carney, Governor of Banque de France François Villeroy de Galhau and Chair of the Network for Greening the Financial Services Frank Elderson:
The catastrophic effects of climate change are already visible around the world. From blistering heatwaves in North America to typhoons in south-east Asia and droughts in Africa and Australia, no country or community is immune. These events damage infrastructure and private property, negatively affect health, decrease productivity and destroy wealth. And they are extremely costly: insured losses have risen five-fold in the past three decades. The enormous human and financial costs of climate change are having a devastating effect on our collective well being.
The authors call for an orderly transition to a low-carbon economy. “The stakes are undoubtedly high,” the authors wrote. “But the commitment of all actors in the financial system to act on these recommendations will help avoid a climate-driven ‘Minsky moment’ – the term we use to refer to a sudden collapse in asset prices.” In other words, the climate change bubble could burst.
The Future
Less than 24 hours remain in this 50th Earth Day, a brief moment in Earth history. Whatever humans do, the earth will be fine. It’s human life and society that’s at risk. My takeaway from 50 years of considering Anders’ image of Earth against a background of the immensity of space is the same as when I first saw it: we humans are all in this together. It is going to take more than Earth Day to bring political will to act on climate.
2019 Kale Bed with 21 plants ready for mulch and fencing.
Temperatures were ideal for yard work so I prepared the bed for kale.
It is important to get kale right because once established, it will produce leaves until November. Sometimes it even over-winters. It is worth the time to measure and plant according to the package instructions.
I put 21 seedlings in the ground and reserved a dozen in case some don’t survive. A neighbor wants some, and after that, I’ll snip the leaves and make a kale salad or two with the leftovers.
My process has a lot of steps after picking up the seedlings at the greenhouse.
I run the lawn mower over the plot to remove any tall grass.
This year I did a burn pile on this plot so using a garden rake I spread the ashes evenly over the surface.
Turn over the soil in bites the size of the spade. Do this by hand. A long-handled spade works best.
Spread fertilizer (composted, granulated chicken manure) evenly over the top. For a 10 x 12-foot plot I used a gallon and a half.
Using the garden rake, break up the clods of dirt until they are fine enough to rake somewhat smoothly.
Make a slight trench with rows three feet apart. Use a yard stick or measuring tape.
Using a hand cultivator, break up the dirt in the trench six inches either side of center.
Using a plastering brick laying trowel, knife the blade into the ground and pull the soil back until the seedling will fit in. Put in the seedling, then fill the hole by hand with loose soil. Measure distance to the next hole in the role as length of the trowel plus the length of blade. Finish planting.
Next I use six inch sections of field tile to protect the seedlings. These will be removed once the stem grows larger. Press each tile section into the ground. The idea is to prevent ground crawling and walking pests from biting the tender young plants.
Use the garden rake to even our the surface and remove compressed areas where the gardener knelt during planting.
Using metal fence posts, pound them into the ground with a post-driver.
Put up chicken wire ensuring to get the bottom to firmly touch the ground. Be sure to leave a place for a gate so you can access the ripe kale.
If mulch is available, mulch deep and completely. Return later if mulch is not available.
Finally water the entire plot thoroughly.
Sounds a bit complicated, but the process has served well during the last few years.
As a gardener I burn brush on a garden plot a couple times a year, rotating the burns on each of seven plots over time. The idea is the mass of the brush is reduced, carbon dioxide is released, and minerals return to the soil. It’s a common practice.
The alternative is purchasing a wood chipper to turn brush into garden mulch — expensive for the amount of brush accumulated in a single gardening season. For the time being, I plan to continue to burn brush because of the carbon cycle.
In 2015 I discussed carbon release from burning wood and other biomass in fires like mine, for home heating, and in the University of Iowa power plant where they burned a mix of fossil fuels and biomass.
What scientists told me was it was better to burn biomass than fossil fuels, partly because the amount of carbon dioxide released into the atmosphere was less than burning coal in experiments they performed.
Ben Anderson, who operated the University of Iowa power plant said, “It’s still combustion but the carbon cycle is what is important there.”
Biomass takes carbon from the atmosphere and stores it until it is released back into the environment in a cycle as old as time. Mining and burning fossil fuels also releases stored carbon which has been stored for millennia. Given our present ecosystem, it is better to leave fossilized carbon where it is, according to the analysis, because releasing it contributes to global warming.
I wrote about this for the local newspaper. The article below was published on Oct. 7, 2015 in the Iowa City Press Citizen with my by line. Many thanks to my editor Josh O’Leary for improving my initial submission.
Biofuel use is a well-known contributor to meeting sustainability goals at the University of Iowa. Since 2003, UI has used oat hulls sourced from Quaker Oats in Cedar Rapids to generate electricity, heating and cooling on campus.
Several chemistry department faculty and students recently completed a study of gas and particle emissions from co-firing coal and two types of biomass versus straight coal at UI’s main power plant.
Researchers also found that using oat hulls with coal reduced carbon-dioxide emissions by 40 percent and significantly reduced the release of particulate matter, hazardous substances and heavy metals.
“The UI is working toward meeting a goal of using 40 percent renewable energy by 2020,” said Betsy Stone, an assistant professor in UI’s chemistry department. “Part of their plan to achieving that goal is the use of biofuel, which is a renewable source of energy, instead of fossil fuel, in this case coal.”
The group was interested in understanding how using biomass instead of coal changed emissions released into the atmosphere, Stone said.
“When burning 50 percent oat hulls and 50 percent coal, we saw a big reduction in criteria pollutants compared to burning 100 percent coal,” she said. “When I say ‘criteria pollutants,’ I’m talking about things like fossil carbon dioxide, sulfur dioxide and particulate matter.”
Use of the 50/50 mixture reduced the mass of particulate matter by 90 percent, Stone said.
While overall CO2 emissions were constant among the three fuels used in the study — straight coal, 50/50 oat hulls/coal, and 3.8 percent wood chips/96.2 percent coal — the use of plant material makes the process more sustainable, Stone said. Biomass takes CO2 out of the atmosphere and incorporates it into the plant. When it’s burned, CO2 is released.
“It’s considered to be a renewable fuel because we have that carbon cycle going on,” Stone said. “With fossil fuels, we’re releasing fossilized carbon. It goes into the atmosphere and takes millions of years to get back to fossilized form again.”
The major take-home message is there is a significant reduction in fossilized CO2, sulfur dioxide and particulate matter, which is beneficial to people living near the power plant, Stone said.
“I thought the study was definitely encouraging and in line with our thoughts that biomass is good for the environment,” said Ben Anderson, UI power plant manager. “Overall, the results are encouraging and provided assurance we are going the right way with the biomass project.”
The biomass project brings the renewable component to the plant, but is also a component of fuel diversity, he said.
“That’s really important for reliable operations,” Anderson said. “Natural gas markets have been known to spike from a cost perspective. If there is a problem with pipeline transport, we can use the biomass and still keep this plant online.”
Maureen McCue, coordinator for Iowa Physicians for Social Responsibility, noted important considerations of this study, including locally sourced fuel options and the avoided cost of buying and shipping coal. McCue called UI’s biofuel efforts “a good use of a resource that might otherwise go to waste.”
“The mixture avoids some of the known adverse health effects associated with burning more coal,” McCue said in an email. “There is no health benefit to anyone unless you assume burning coal is obligatory/unavoidable and thus count as benefited the person(s) who would have been impacted by more coal.
“It’s like saying not hitting your head with a hammer is a health benefit,” she added. “No one wants to risk their health breathing coal emissions or headaches by hammer if there are alternatives.”
I looked in the recycling bin and there were only eight items in it. Thursday is our day to leave the bin at the end of our driveway and I’m going to wait until next week.
It’s not that we’re throwing more in the trash instead of recycling. The trash bin is completely empty, making the second week in a row it remains in the garage as the trash collector comes through the neighborhood.
We’ve learned to reduce the amount of stuff we use, recycle what is accepted, and reuse what can be. In part we do that because of my participation in the first Earth Day on April 22, 1970.
Do the math. The 50th Earth Day is Monday and the news is that few are aware or interested, based on my personal interactions with people and reading news coverage.
I’ll have more to say on Monday, but a couple things are clear.
In the long run, the Clean Air Act, the Clean Water Act and other environmental laws enacted since the famous Earthrise Photo have run their course. The U.S. Environmental Protection Agency did good work for a time, which included measurable environmental improvements, yet in today’s de-regulatory government their future effectiveness is being gutted in favor of business interests.
The regulatory environment created beginning with President Richard Nixon didn’t do the job. Climate scientists indicate society is in a position where if we don’t de-carbonize and fast, within the next decade or so, there will be dire consequences. The Earth will be fine, but the people on it will not.
We see the effects of global warming everywhere. Vegetable farmers discuss ways to produce a crop that accommodates extreme weather we face. While row-crop farmers know how to a get a crop in the field in record time, the nutritional quality of food they produce is less because of global warming. This is not to mention the flooding in Iowa where 56 counties have been declared a disaster by the governor. We’ve had our share of straight line winds, drought, excessive and heavy rainfall, and flooding during the time we’ve lived in Big Grove Township.
We had good intentions on the original Earth Day. 50 Years later, we need a better, smarter movement to reverse global warming. Even if we do create such a movement, we let the problem go on so long the ecosystem will continue to change in ways that seem totally new and not for the better. There is no going back to some halcyon time when all things were great.
I’m not depressed about our current situation, even if there is cause. Our only hope is to remain engaged, to engage in actions that reduce our carbon foot print and mitigate the effects of damage already being done. With help from friends, I continue to believe that is possible.
Earlier this century India and China decided to build fleets of coal-fired power plants as their citizenry entered a world most Americans and Europeans already knew for its modernity and comparative affluence. The two populous states required more electricity.
Carbon emissions from the new plants have come home to roost. According to the International Energy Agency,
Global energy consumption in 2018 increased at nearly twice the average rate of growth since 2010, driven by a robust global economy and higher heating and cooling needs in some parts of the world. Demand for all fuels increased, led by natural gas, even as solar and wind posted double digit growth. Higher electricity demand was responsible for over half of the growth in energy needs. Energy efficiency saw lacklustre improvement. As a result of higher energy consumption, CO2 emissions rose 1.7 percent last year and hit a new record.
China, the United States, and India together accounted for nearly 70 percent of the rise in energy demand, according to the report. Failure to reduce carbon emissions is a result of the lack of political will to adopt renewables as aggressively as their lower cost warrants.
Having lived through the India-China build-out of coal plants, I understand why and importantly that they are planning renewables and to some extent, natural gas and nuclear power, for new electricity generation. The writing is on the wall for coal’s hegemony according to Energy Innovation:
America has officially entered the “coal cost crossover” – where existing coal is increasingly more expensive than cleaner alternatives. Today, local wind and solar could replace approximately 74 percent of the U.S. coal fleet at an immediate savings to customers. By 2025, this number grows to 86 percent of the coal fleet.
While their analysis does not adequately consider stranded costs, it is doubtful India or China will abandon coal-fired power plants built since the turn of the century as they are comparatively new. That is, unless the climate crisis is adequately recognized by governments.
Any doubt climate change is real? The New York Times reported on the flooding in Hamburg, Iowa:
“I’m looking at global warming — I don’t need to see the graphs,” said Hamburg, Iowa’s mayor, Cathy Crain, referring to the role of climate change in increasing the frequency of extreme weather events. After two record-setting floods in a single decade, Ms. Crain said, “I’m living it and everybody else here is living it.”
We shouldn’t be shocked by the International Energy Agency report as rising emissions were planned by China, India and the United States a long time ago. There is a long tail on carbon emissions and government is largely responsible to turn the corner. The report highlights we are going the wrong direction.
How many more tragic incidents like the one in Hamburg are necessary before government acts on climate? More people are ready to act on climate now but we haven’t reached our politicians… yet.
Rural Johnson County – 140th Street NE west of Ely Road on March 23, 2019.
During a tour of my usual spots to observe flooding it doesn’t look as bad as it has.
In 2008, the flood waters came to within 100 yards of our home before receding. We are nowhere near that now.
Yesterday afternoon Governor Kim Reynolds issued a press release saying the president had approved a major disaster declaration for 56 Iowa counties. Hazard mitigation funding became available for the entire state.
What’s going on?
“Are we just rolling snake eyes over and over or is there something happening here?” Erin Murphy of Lee Enterprises asked on Iowa Press this weekend.
“We have 147 years of temperature and precipitation records for the state,” Iowa State Climatologist Justin Glison responded. “The trend shows us warming and with the warmer atmosphere, a warmer surface temperature, we’re able to hold more water vapor in the atmosphere. That gives us a higher probability of having more precipitation events. What we are seeing over the past thirty years is that the intensity of precipitation events is increasing… Yes, we are moving into a new type of precipitation regime.”
No mention of the words “climate change” and that’s okay. Glison’s message is what I have been saying the last six years, and part of what Al Gore said the two times I heard him present his slide show. The current flooding is climate change happening in plain view. It is time to do something to mitigate not only the damage caused by climate change but the changing climate itself.
What should we do about climate change? Embrace the truth about what this scientist said. Then develop the political will to change human activities that contribute to global warming in a way that makes sense and creates a resilient culture.
The rest of my day seemed anticlimactic. While crossing the Cedar River bridge on Highway One I decided to visit the Ace Hardware Store in Mount Vernon to see if they had a replacement part for the faucet handle in the bathroom.
I entered the roundabout at the intersection of U.S. Highway 30 and Route One. It is a bit confusing but I was able to decipher the signs related to which lane was correct for my trip. I like the roundabout for intellectual reasons, although most locals hate it.
Before the roundabout was completed in October 2013, the intersection was one of the five most dangerous in the state, based on frequency of accidents. In the years since the new roundabout opened, the frequency of accidents remained higher than expected. The intersection is currently exhibiting a crash frequency of 16.8 crashes per year according to a 2018 study. The expectation was there would be from six to eight crashes per year. To make a 60 percent reduction in accident frequency, the study recommends better driver education and improved signage near the roundabout. In other words, Iowa drivers are not finding navigation of the roundabout intuitive and it shows.
I arrived in Mount Vernon and parked across the street from the small hardware store. The future of small city retail was on display as I walked through the entrance. As an employee of a home, farm and auto supply store my radar was up to take in the sales process.
Two cashiers greeted me as I entered and asked if they could help. They directed me to the plumbing aisles which were easy to find in the small space. I walked past a popcorn machine that offered fresh, hot popcorn to eat while shopping. Eating and retail seem inseparable in the 21st Century. I declined to sample a bag. I quickly found a selection of faucet handles.
Using my handheld device, I had taken a photo of the old handle with a ruler held up to it from two angles. I sought an exact match. Within a couple minutes, a sales associate walked up and asked if he could help me find something. I said yes as I wasn’t finding what I wanted. He confirmed the display represented what was on hand and led me to a dual-monitor computer where he researched alternatives. The idea was if we could find the part, the associate would order it on the spot. We looked through four examples, both the Ace and manufacturer brands and couldn’t match the size.
In my experience, expanding product offerings from a retail store’s physical inventory is essential to survival in small cities and towns. It harkens back to the early days of the Sears catalogue. While there were no mobile or home computers back in the day, modern retail at its best emulates the idea there is a broad array of available products that with time can be delivered just about anywhere. The difference between my experience at Ace Hardware and a large on line retailer like Amazon.com is the personal attention I received from everyone I encountered at the store. That service is what satisfies our human need for personal interaction, and is likely to make us a repeat customer. In doing so, local retailers can learn and work toward sustainability.
What do climate change, roundabouts and retail stores have in common? I’m not sure, but that was my day in society.
