Enjoying late summer warm waters in Lake Michigan

Posted on by

A late summer swim in Lake Michigan can be exciting. It is early September or even later and you test out the water. Dip a toe in. See if it is warm. And sometimes it is. Warm enough to jump in, swim, play. Even if school has started or fall seems to have already begun (even if it is not “officially” started by the calendar) or municipal pools have already closed, the warm waters of the lake prolong summer.

As someone who has visited Lake Michigan throughout my life, these are good moments. Lake Michigan is not always warm enough for swimming, whether testing out the chilly waters at Memorial Day or finding that a change to a north wind overnight has cooled the water temperature too much.

There may be more late summer days like this in the future as the Great Lakes are warming:

Lake Michigan is heating up. The lake’s surface temperature has surpassed the running average dating back to 1995 nearly every day this year, according to National Oceanic and Atmospheric Administration (NOAA) data. And it’s not just one Great Lake. All five are warming. The massive bodies of water, which provide drinking water to more than 30 million people, are among the fastest-warming lakes worldwide, according to the federal government’s Fifth National Climate Assessment.

It’s a trend that doesn’t show any sign of slowing. As heat trapping-greenhouse gasses continue to accumulate in the atmosphere, the Great Lakes region is projected to grow warmer and wetter in the years and decades to come. Over a fifth of the world’s supply of non-frozen freshwater flows through the five connected Great Lakes, forming the Earth’s largest freshwater ecosystem.

Beyond a longer swimming season, might this lead to more Great Lakes tourism? Different conditions (algae, different fish, etc.) for swimmers and other recreational users of the lake? Will the lake remain an attractive place to visit?

Warmer temperatures and transporting and storing frozen food

Posted on by

If outside temperatures are warmer, it takes more energy to cool food. This could be a problem:

It’s easy to take the huge variety of foods available at the grocery store for granted. But it’s possible because of the technology—and huge amount of energy—that keeps dairy, meat, fruits, and vegetables cold, safe from rot, and free of bacteria growth. To find out how the heat is affecting the process of keeping things cool, I talked to Nicola Twilley, the author of Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves. Our interview has been condensed and edited for clarity…

The estimate is that for every degree-Fahrenheit rise in ambient temperature, your refrigerator uses 2 to 2½ percent more energy. So it’s significant. It has to work significantly harder to cool things. So there is a real problem…

We can’t just store our food at a much warmer temperature. But there actually is a big push to raise the temperature that frozen food is stored at by a couple of degrees. Currently frozen food should be transported at minus 18 degrees Celsius, or zero degrees Fahrenheit. But for every degree that you go below minus 12 degrees Celsius, you’re using an extra 2 or 3 percent energy.

The company that owns Birds Eye [the frozen foods giant] has studied this and found that if their foods were stored at minus 15 degrees centigrade, rather than minus 18, it wouldn’t affect the food safety or the texture or taste or nutrition level. And it would likely reduce energy consumption by about 10 percent, which is a lot. All the big frozen-food warehouses and shipping companies are behind this right now.

It sounds like transporting frozen food at slightly warmer temperatures could work.

But there are bigger issues at play here. How much frozen food should there be and how far should it be shipped? How about refrigerated food? Americans are pretty used to all sorts of cold and frozen food options that come from who knows where.

Talk about needing more local food has been going on for a while. Some had concerns about oil use; what does it take to transport food thousands of miles to please consumers elsewhere in the globe? Or it might be about agriculture more broadly: do people eat what is available each season instead of depending on food grown elsewhere that makes certain food available all year round?

I would guess many American consumers still have little idea where their food – fresh or frozen – comes from. It is just available. I can go roughly two and a half miles from where I live and visit five different sizable grocery stores. Expand that radius to five miles and it adds numerous stores. What if I had fewer shopping options, whether in terms of locations or fewer food items when shopping in each store?

It is interesting to hear that companies might be willing to make changes as it could save money and be more sustainable. What other parts of the system, whether at the policy level or for those who transport goods or on the consumer side, would address the issue of energy use for frozen and cold food?

The Rust Belt as potential “climate refuge”

Posted on by

If climate change prompts people to move, could the Rust Belt provide good places to live?

Gibbons, who now works at the climate consulting firm Farallon Strategies, sees Michigan’s future in the Californians unsettled by wildfire. Those people are going to move somewhere. And so they should be persuaded to come to Michigan, she says, before they move to places like Phoenix or Austin. The Great Lakes region should market itself as a climate refuge, she thinks, and then build an economy that makes use of its attributes: the value of its water, its land, its relative survivability. In her vision, small northern cities, invigorated by growing populations, somehow manage to blossom into bigger, greener, cleaner ones.

“There’s no future in which many, many people don’t head here,” Gibbons told me. The only question is whether “we don’t just end up being surprised by it.” And so Gibbons wants to see the Great Lakes states recruit people from around the country, as they did during the Great Migration. Back then, recruiters spread across the South to convince Black people there that opportunity awaited them in the factories of the North: That’s what helped make Ypsilanti.

Internal migration has shaped the United States before, such as in the Great Migration cited here and the move of many West in different waves. But, has decades of decline in an entire region been reversed by internal migration?

Later in the article we read that some residents would not be thrilled with the idea of lots of outsiders moving in. I wonder how this might play out. Take a city like Detroit. Once one of the most populous American cities, the city lost hundreds of thousands of residents. The city’s status has dropped precipitously. Lots of people moving in could change things but don’t Americans tend to see population growth as a sign of health and vitality?

One last thought: would Rust Belt communities be willing to offer climate-related incentives to further entice people to move? A number of American communities already offer incentives. Imagine a “green moving package” that provides some assistance in finding affordable housing and work with limited climate impact.

Look out for the floating house

Posted on by

Could floating houses become more popular in the coming years?

About 3 billion people, roughly half of the world’s population, lives within 125 miles of a coastline, according to the Population Reference Bureau. Eventually, coastal cities could claim not just the waterfront, but also the water, building in their harbors, bays, canals and rivers.

It’s already happening in the Netherlands. With a third of its land below sea level, the country has floating offices, a floating dairy farm and a floating pavilion. Floating buildings are often built atop concrete and foam pontoon foundations, allowing them to sit on the water, and rise and fall with currents.

Proponents of the design argue that these buildings protect the environment. While a 2022 study published in the Journal of Water & Climate Change found that floating structures can have a positive benefit, attracting birds to nest and providing habitat and food for sea life, the study also found that they can impact light, currents, wind patterns and water quality…

Yet, as sea levels rise, low-lying countries like the Maldives are grappling with an existential threat, and building on the water is a way to create land from the encroaching sea. The government, in partnership with the developer Dutch Docklands, is building an entire floating neighborhood in a lagoon 10 minutes by boat from Malé, the nation’s capital.

Next year, the first phase of the 5,000-modular unit development will open — apartments, schools, shops and restaurants built on a floating landscape of serpentine jetties fitted together like Lego pieces. “That is the future,” said Mr. Olthuis, the Dutch architect, who developed the master plan for the Maldives development.

Even without the threat of climate change, these options could create interesting new possibilities in places around the world. Imagine visiting a floating area or more residential units with waterfront views and access.

At the same time, I imagine it would take some work to start mass-producing floating housing. Would there be common sizes or units? Is the infrastructure in place in many locations to accommodate such housing?

McMansions and combating climate change

Posted on by

A letter to the editor in California includes McMansions on a list of items that need attention in order to fight climate change:

Wildfires are increasing but McMansion developments are underway in brushland.

McMansions have long been connected to environmental concerns. This includes their presence within sprawling suburbs and neighborhoods where driving is necessary and a lot of land is used. It includes the materials required for each home and yard. It includes the use of resources to heat and light such homes.

The concern expressed above is more specific. McMansions are linked to wildfires and brushland. This suggests these homes are being built in places where they should not be built or in places that are vulnerable to wildfires. If McMansions were not in these locations, wildfires would affect fewer people.

I wonder, however, if McMansion is shorthand here for any larger single-family home. Do expanding metropolitan regions in California and other states have climate implications? When people move to what used to be small towns surrounded by more open land or continue to move out into dry suburban fringes, isn’t this more problematic than large McMansions with bad architecture?

Claim: Lake Michigan has so much water that “supply will never be a problem for the [Chicago] region”

Posted on by

Water supplies in the Southwest are limited but Lake Michigan holds a lot of water communities in the Chicago region can access:

Lake Michigan holds more than 1 quadrillion gallons of water, so supply will never be a problem for the region.

Should we be so confident about this? Lake Michigan is large and the Great Lakes contain roughly one-fifth of “the world’s supply of surface fresh water.“

Sure, the Chicago region has limited population increases. The Midwest at large is not exactly growing like the Sunbelt. But, lots of people and governments rely on this water and climates and ecosystems change.

The context for this quote is a dispute between local governments in the region about obtaining water. Hundreds of millions of dollars, perhaps billions, are on the line. People need water. For now, it is there and it probably will be there for a long time…but it is not guaranteed to be there.

How much all the buildings in New York City weigh

Posted on by

New York City has a lot of buildings in its 300+ square miles. All those structures weigh a lot:

New geological research warns that the weight of New York City’s skyscrapers is actually causing the Big Apple — whose more than 1 million buildings weigh nearly 1.7 trillion pounds — to sink lower into its surrounding bodies of water.

Given the innovations that helped give rise to all of these buildings, can we expect innovative solutions to the consequences of all that weight? One approach would be to create barriers between the surrounding waters and the habitable areas. However, that does not fully address the weight and the ground under the buildings. Are there ways to prop up large structures?

If winter was less harsh in the Chicago area, would residents like this?

Posted on by

Let’s say winters in the future in the Chicago region turn out to be not as cold, do not involve as much snow, and/or include more warm days. In just the last month, we have experienced wind chills of roughly -30 degrees below zero and 50 degree days. The Chicago region has had moments of winter but not a full month of winter. Would Chicago residents like a long-term shift away from winter?

On one hand, many Chicago area residents complain about the winter. They make clear their opinions about the cold, snow, potholes, salt, longer traffic times, winter gear, heating bills, and more. At least a few vacation in warmer climates during the winter and some move to warmer climates.

On the other hand, it is hard to imagine the Chicagoland experience as it is known now without winter. What about the social capital created by griping together? The possibility of a white Christmas? The pride about shoveling and still doing life when talking to people in parts of the country where a light amount of snow shuts everything down? Invigorating winter outdoor activities? Supposed “Bears weather”? Jokes about the two seasons of winter and construction? And so on.

Perhaps new weather patterns would lead to a reconfigured understanding of what winter is. People can adapt to change over time. They can find different ways to bond and different experiences or group identities that bring them together. The long-told tales of the Blizzard of 1967 or Snowmageddon 2011 will fade further into the archives. Chicago could still have a winter that is different than the South or West even if it s different than what it is in the past.

Creation care, “practical love,” and the American suburbs

Posted on by

One evangelical leader is asked about caring for the environment as a Christian imperative and they connect the issue to the American suburbs:

If you play the visionary, what must the church or mission agency do now to prepare for the coming changes? How will they take the gospel message to the world?

Much of what we will have to do is practical love, not just suburban evangelism. I don’t know how leaders of World Vision, SIL, Compassion International, or TEAM should change their strategies—but they must be talking about this. Do the analysis, and anticipate the threats.

Will “practical love” be necessary also in the suburbs?

As environmental impacts ramp up, more and more people will discover they are vulnerable. On the West Coast, the Colorado River is running dry. An entire swath of the country is or may soon be on water rationing, and I don’t know how to deal with that. We are not as protected from environmental impacts as we think we are.

Supply chain issues are affecting cellphones and new cars, but what happens when it hits the grocery stores? Trace it back, and you will discover that there were no apples, because the pollinators were absent. This brings it home, but by then, it will be too late.

I see two connections to suburbs in this discussion:

  1. There is “suburban evangelism” and this contrasts with “practical love.” To address changes in the environment, “suburban evangelism” may not be enough.
  2. The environmental issues will eventually come to the suburbs. Suburbanites might feel like they are protected by a certain level of wealth and distance from immediate dangers, but environmental change will find them.

In other words, there is a particular way of Christian faith that aligns with suburban life. Right now, that faith does not regularly intersect with climate change or environmental issues.

A much larger, and related, question: what about suburban faith does not line up with addressing climate change and other important social issues? (I have some thoughts about this: I have an analysis titled “Faith in the Suburbs: Evangelical Christian Books about Suburban Life” in this book.)

Preserve a McMansion to help combat climate change

Posted on by

As part of an argument against demolishing buildings, McMansions should also be preserved to help address ecological challenges:

Anyone interested in mediating the worst ongoing outcomes of the present climate catastrophe must also disconnect the idea of development from our notion that it proceeds only in cycles of demolition and new construction—a pattern that prevails because it is maximally legible to our existing structures of debt, financialization, and speculation. About 80 percent or more of a typical new house’s lifetime ecological and energetic impact comes through the operations of initial material extraction, manufacturing, transportation, and construction; and then of eventual demolition, further transportation, and decay. Sustainable buildings are therefore not new buildings—however fuel-efficient their machines and materials. Sustainable buildings are buildings that have been sustained. Merely by being seventy-five years old and in working order, Geller I was radically sustainable. For that matter, any dumb 1990s McMansion down the block is almost as ecologically precious as Geller I. That McMansion’s judicious conservation, too, is part of ecological stewardship.

This kind of conservation comes not by preserving any one house exactly as it is, but by shifting from a fantasy of perpetual newness or untouchable oldness to the best practices that Gropius and Breuer cherished in old New England farmhouses: renovation, addition, retrofitting, and all manner of adaptive reuse that allows ever more lively and dignified density. The model of development becomes less one of the sudden appearance and disappearance of structures, and more one of continuous emendation and repair. Not incidentally, this affords ever more innovative ways of living intergenerationally and integratively—rather than dwelling in the built residue of past generations’ conventions about how families and communities ought to live.

Demolition and rebuilding takes a lot of resources. Additionally, rehabbing existing homes can help keep the character of a neighborhood or community consistent.

The twist above is that this might be the preferred course for McMansions. Such homes are not usually renowned for their architectural quality. Critics are not fans of the ways in which they were constructed, their drain on resources, and their ongoing presence.

I have argued before that at least a few McMansions will be preserved, at the least to mark a particular era and design. Preserving them to help combat climate change moving forward might be a unique feature of this decade.
