Cities consume more than two-thirds of the world’s energy. Copenhagen is a city that’s determined to become the first carbon-neutral capital and, in the process, is showing that sustainability improvements are good for the economy.

Copenhagen, where Erik’s Swedish-Danish relatives live, is showing the world that cutting carbon emissions to fight global warming can actually reduce energy prices and boost the economy. In a win-win for all concerned, big steps by the local energy company are complemented by the small steps of individuals who know that biking everywhere is good for both the environment and personal health.

Lin Taylor writes for the World Economic Forum, “Around the world, more than 70 major cities have pledged to end their reliance on fossil fuels and stop pumping out climate-changing emissions by 2050.

“But Copenhagen — a city of wind turbines, bicycles and reliable public transportation – thinks it can go even further: It intends to accomplish that shift in just seven years. It will require a complete reimagining of how the Danish capital is powered and designed — and a lot of cyclists. …

“While other cities have parking garages for cars, Copenhagen has them for bicycles. Virtually all its 600,000 residents own a bicycle, and the city has 375 kilometres of dedicated cycle lanes.

“The harbour-rimmed municipality also is mostly powered by clean energy — and it has its own renewable energy company and wind turbines. Running its own energy systems is one of the reasons Copenhagen is already well on track to being carbon neutral – meaning it will produce no more carbon emissions than it can offset elsewhere. …

“In 2017, Copenhagen produced about 1.37 million tonnes of climate-changing gases, down 40 percent from 2005, according to city figures. That’s about 2.2 tonnes of emissions per capita, one of the lowest rates for a European city. The city said the reduction in emissions was largely due to a switch to wind energy under HOFOR, the city’s own utility company. …

“Around the world, cities consume more than two-thirds of the world’s energy and account for about three-quarters of carbon dioxide emissions, according to the United Nations. That means finding ways for cities to become carbon neutral will be key to meeting the Paris commitment to keep the rise in global temperatures to ‘well below’ 2 degrees Celsius above pre-industrial levels. …

“In its quest to cut emissions, Copenhagen has another distinct advantage: For over 100 years, the city — and Denmark as a whole — has relied on district heating, a system where heat is produced and supplied from one neighbourhood or area plant, instead of per household. That means the city itself can make the switch to cleaner energy for large numbers of residents, cutting carbon emissions by over half compared to the use of individual gas or oil boilers, HOFOR says.” It adds:

“The city also has a newly-built district cooling system, which uses seawater to cool buildings and households, cutting energy consumption up to 80 percent compared to traditional methods of air-conditioning.

“By 2025, the city aims to be powered entirely by wind, sun, geothermal energy, waste, and wood and other biomass. Yet despite its huge investment in new, clean technologies, one of the city’s big priorities is cutting prices for energy users. …

“[Jørgen Abildgaard, director of the city’s climate programme,] said it was crucial to work closely with industries such as construction and transport to devise business models and technologies that work both to meet business goals and cut emissions. …

“As the city’s emissions-cutting commitments have grown, so has its economy, which has seen 25 percent growth over the past two decades.” More at the World Economic Forum, here.

The plastic bicycle path in Zwolle, the Netherlands, is a test for building roads from plastic waste in the future.

I don’t know if it’s because, historically, they’ve had to protect their land from the encroaching sea, but the Dutch seem to be repeat innovators. This blog has covered a lot of new ideas from the Netherlands. (3-D printed houses, anyone? Wind power for trains?) Today’s post is on a possible use for discarded plastic bottles.

Daniel Boffey writes at the Guardian, “The world’s first plastic bicycle path made of recycled bottles, cups and packaging has opened in the Netherlands, as part of a pilot that could see similar roads open up across the country.

“The 30-metre path, made of recycled plastic equivalent to more than 218,000 plastic cups, is expected to be three times as durable as an asphalt alternative. It also contains sensors to monitor the road’s performance, including its temperature, the number of bikes that pass over it and its ability to cope with the traffic.

“The prefabricated sections of cycle path are light and hollow making them easy to transport and 70% quicker to install. Cables and utility pipes are able to be easily fitted inside, and the path is designed to drain off rainwater. … It is believed that many of the benefits of the paths will apply to plastic roads.

“The path’s inventors, Anne Koudstaal and Simon Jorritsma, said: ‘This first pilot is a big step towards a sustainable and future-proof road made of recycled plastic waste. When we invented the concept, we didn’t know how to build a plastic road, now we know.’

“Asphalt concrete is responsible for 1.5m tonnes of CO2 emissions a year, equivalent to 2% of global road transport emissions. …

“Earlier this year the EU [European Union] launched an urgent plan to clean up Europe’s act on plastic waste and ensure that every piece of packaging on the continent is reusable or recyclable by 2030. … Each year, 25m tonnes of plastic waste is generated by Europeans, but less than 30% is collected for recycling.”

The idea has real possibilities, but the concerns of groups hoping to end the use of plastics altogether need to be addressed. “Plastic Soup has warned that small particles of the plastic could find their way into the living environment due to heat, wear and run-off.” More at the Guardian, here.

I’m just glad people are trying to find solutions to some of the damage that human activity has done to the planet. The issues are in the news right now as both great powers and small, climate-impacted countries are meeting in Katowice, Poland, to improve on the Paris Agreement.

By the way, if you are on twitter, do follow Sweden’s 15-year-old climate activist Greta Thunberg (@GretaThunberg), who is speaking truth to power in Poland: “I will not beg the world leaders to care for our future. I will instead let them know change is coming whether they like it or not.” I just read that Venice is likely to succumb of sea-level rise. Greta’s urgency is warranted. Young people give me hope.

And read a wonderful, inspiring book by former president of Ireland Mary Robinson called Climate Justice, which connects human rights and poverty to the effects of global warming and offers hope in the shape of brave, ordinary people.

A surfeit of carbon in the oceans is destroying coral reefs, home to a wide variety of marine life. But a few reefs may offer lessons for survival.

Earlier this month, I posted about an improbably successful coral reef in the busy harbor of Cartagena in South America. Scientists were thinking that if they could figure out why the reef was doing well despite inimical conditions, they might be able to save other reefs.

Now comes a story about scientists finding hopeful reefs in the Pacific Ocean and elsewhere.

Josh Gabbatiss reports at the UK’s Independent, “Sections of coral in the Pacific and the Caribbean are fighting back against the global threats that have decimated reefs worldwide. While the discovery does not allow any room for complacency in the fight to save the world’s reefs from extinction, scientists are tentatively optimistic about what they can learn from these pockets of resistance.

“Climate change, hurricanes and human activities such as intensive fishing have destroyed vast swathes of the planet’s reefs, but in a new study scientists found this destruction was not uniform. …

” ‘There are a number of reasons why one coral reef might survive while its neighbour dies,’ said Dr James Guest, a coral reef researcher at Newcastle University who led the study. ‘It could be that the location is simply better for survival – deeper water that is outside the storm tracks, for example.’

“Coral reefs might also possess certain biological characteristics that make them able to resist damage, or characteristics of their environment may allow them to rebuild themselves effectively following damage. …

“These findings were laid out in a study published in the Journal of Applied Ecology that explored dozens of these cases from tropical regions around the world. …

“The study’s lead author, Professor Peter Edmunds from California State University, Northridge, [says], ‘There are kernels of hope in places where corals are doing better, or where they are doing less badly than elsewhere and these places provide us with a focus of attention that might be used to enhance coral conservation efforts.’ …

“Scientists have voiced the need for ‘radical interventions’ such as genetic modification of corals.”

OK, I’ll let you read the rest at the Independent while I ponder the metaphors here.

Since my sister’s surgery and her diagnosis of a serious kind of cancer, I feel like I’m living in metaphor, by which I mean a couple things. For example, I can’t read about certain reefs that heal themselves because they have unique characteristics (or about scientists racing the clock to figure out how to replicate that) without thinking about how every cancer and every patient’s response to cancer is different and how researchers and physicians are trying to understand all the ways that plays out (sometimes using genetics, like the coral researchers). I also mean that literary metaphor, especially poetry, is among the few things that can help me get my head around what is going on. When you can’t understand, metaphor can be calming and provide a sense that eventually there might be answers.

An urban farm flourishes on a rooftop in the heart of Paris.

I never can resist a story about urban rooftop gardens, which not only bring fresh produce to city dwellers but also make use of empty space and help reduce carbon in the atmosphere.

I have blogged about them a lot. There was the post about a rooftop garden in Montreal, here. Another about Higher Ground in South Boston, here. Suzanne and Erik’s former church in San Francisco, Glide Memorial, made its rooftop garden a community-building activity for Tenderloin residents. And this was an article about a Whole Foods that aimed to harvest 10,000 pounds of food a year from its rooftop in Lynnfield, Mass.

Today’s story comes from Paris.

Freelance blogger Aimee Lutkin writes at the World Economic Forum blog, “The mayor of Paris, Anne Hidalgo, was elected in 2014 with the intention to improve the city’s green spaces as a part of her platform. …

“In 2016, her administration launched Parisculteurs, a campaign that is working to cover 247 acres of rooftops and walls in Paris with greenery by 2020.

“One third of that greenery will specifically be set aside for urban farming. To date, 74 organizations have signed a charter to work with the city on planning this enormous enterprise. The city has already approved 75 projects for development, which are estimated to produce more than 500 tons of vegetation.

“The deputy mayor of Paris, Penelope Komites, [told CNN] … ‘Citizens want new ways to get involved in the city’s invention and be the gardeners.’ …

” ‘Three years ago, people laughed at my plan. Today, citizens are producing [food] on roofs and in basements. We are also asked by numerous cities around the world to present the Parisian approach,’ she said.

“And they already have their success stories. … La Chambeaudie started shortly after Parisculteurs was announced in 2016, but now grows over 40 varieties of plants and herbs using a hydroponic system …

” ‘We’ve seen a real craze among Parisians to participate in making the city more green,’ said Komites. ‘Urban agriculture is a real opportunity for Paris. It contributes to the biodiversity and to the fight against climate change.’

“And it also means jobs. According to Komites, Parisculteurs has created 120 full-time jobs.”

Inka Saara Arttijeff is the adviser to the president of the Sámi Parliament and hails from a family of Sámi reindeer herders. She represents Finland at international climate change summits. 

When I was in Sweden last year, I visited the history museum in Stockholm, where I learned a little about an indigenous population called the Sámi. I had previously heard them called Laplanders, but Wikipeida says they don’t like that term:

“The Sami people (also known as the Sámi or the Saami) are a Finno-Ugric people inhabiting Sápmi, which today encompasses large parts of Norway and Sweden, northern parts of Finland, and the Murmansk Oblast of Russia. The Sami have historically been known in English as the Lapps or the Laplanders, but these terms can be perceived as derogatory.”

Sonia Narang of the GlobalPost recently reported on the Sámi people and the threat that global warming poses for their way of life.

“Inka Saara Arttijeff and her family gather in the cozy kitchen of their red, wooden house, as a pot of soup simmers on the stove. They live at the edge of a frozen lake in the storybook village of Nellim, up toward the far reaches of northern Finland. … Arttijeff is part of a family of indigenous Sámi reindeer herders who are unfazed by short days in subzero weather.

“The Sámi [are] known for their centuries-old tradition of herding reindeer. … However, the warming climate has threatened to disrupt the Sámi people’s tradition of reindeer herding. … The combination of weather changes and increased tree cutting has made it harder for reindeer to find food, and it’s altered their migration patterns.

“ ‘Reindeer herding represents a way of life,’ Arttijeff said. … Arttijeff is one of a growing number of outspoken Sámi women who are taking their voices well beyond the borders of their small villages. The 33-year-old is the adviser to the female president of the Sámi Parliament, Tiina Sanila-Aikio, and represents Finland on the world’s stage. Every year, Arttijeff joins a delegation of indigenous representatives at the UN’s climate change talks. In between all that, she is also a graduate student in international relations and law. …

” ‘For reindeer herding, [we] need forest that is healthy,’ Arttijeff said. … Finland’s state-owned forestry agency, Metsähallitus, manages about one-third of the country’s forests, and it’s also responsible for harvesting and selling timber. Kirsi-Marja Korhonen, a regional director and environmental specialist at Metsähallitus, … notes 60 percent of trees on Sámi lands are in protected areas.

“That still leaves large swaths of Sámi forests up for grabs, reindeer herders say, and they point to clear-cutting of productive forests. …

“[Saara Tervaniemi, a reindeer herder] says it’s critical to monitor forestry activities on her people’s lands since logging is eroding the culture she hopes to pass down to her children. …

“Since Sámi women are primarily responsible for child care and passing on their culture to the next generation, reindeer herding has become an important issue for them, especially as logging and climate change have intensified in recent years. …

“It’s not just reindeer herding that’s at risk — it’s the four other Sámi livelihoods, too: fishing, gathering, hunting and handicrafts. ‘For all of those, you need materials from nature,’ Arttijeff says. ‘If the nature changes, you cannot do traditional livelihoods anymore. So, if that changes, everything changes for us.’ ”

Scientists hope to restore damaged coral on the Great Barrier Reef with a technique that has seen success in the Philippines.

As I was preparing this post on an effort to save the Great Barrier Reef, I stumbled upon the news that the 37-year-old ocean warrior behind the climate-change movie Revolution, Rob Stewart, died a year ago in a dive off Key Largo.

That gives a whole different cast to my thoughts. I was going to say something about how happy he must be about the new coral-breeding program that offers a “glimmer of hope” to the Great Barrier Reef. Now it’s “how happy he would have been.” The world can ill-afford to lose an energetic ocean crusader like Stewart.

As the Guardian reports, the coral-breeding project has seen success in the Philippines and is now being tried in Australia.

“Scientists have stepped in as environmental matchmakers by breeding baby coral on the Great Barrier Reef in a move that could have worldwide significance.

“Coral eggs and sperm were collected from Heron Island’s reef during [the November 2016] coral spawning to produce more than a million larvae. The larvae were returned to the wild and placed on to reef patches in underwater mesh tents, with 100 surviving and growing successfully.

“The lead project researcher and Southern Cross University professor Peter Harrison, who discovered mass coral spawning in the 1980s, says the ‘results are very promising.’ …

“The project has the ability to restore damaged coral populations and has seen similar success in the Philippines where blast fishing using explosives to kill schools of fish has destroyed coral.

“The Great Barrier Reef Foundation managing director, Anna Marsden, said the research is an important step for the reef, but one that should not lessen the strong action needed against climate change.”

That’s because, as I learned watching Stewart’s movie, it’s the CO2 resulting from climate change that is the big danger.

The Swinomish community in Washington State has seen the future in rising waters. Much of the tribe’s 15-square-mile reservation is at or near sea level.

Today I have a story about how recognizing climate change can put a community one step ahead of the game. Indigenous people around the country are taking steps to deal with the inevitable before it’s too late.

Terri Hansen writes at Yes! magazine, “Chief Albert Naquin was astounded when emergency officials warned him in September 2005 that a second hurricane would soon hammer the southern Louisiana bayous where Hurricane Katrina had struck less than a month earlier. The leader of the Biloxi-Chitimacha-Choctaw tribe, Naquin took to the Isle de Jean Charles’ lone road to urge residents who had returned home after Katrina to leave their listing, moldy homes once again. …

“Hurricane Rita flooded the island for weeks, adding insult to injury that had already reduced the tribe’s homeland to a sliver of what it once was. Rising sea levels, hurricanes, erosion from oil production, and subsidence have since shriveled the Isle de Jean Charles peninsula from 15,000 acres to a tiny strip a quarter-mile wide by a half-mile long. There were once 63 houses flanking the town’s single street. Now only 25 homes and a couple fishing camps remain. …

“In January, Louisiana received a $48 million grant from the Department of Housing and Urban Development to move the Biloxi-Chitimacha-Choctaw and Houma Nation tribal members to more solid ground and reestablish their communities, making tribal members the first climate change refugees in the United States. …

“Across the country, 24 tribes have responded to climate change with plans for adaptation and mitigation, and more are in development. …

“As rising temperatures cause heatwaves, droughts, floods, wildfires, and increase the severity of weather events, tribes are on the forefront in respect to both degree of impact and in initial efforts to respond to adaptation, said Ed Knight, director of planning and community development for the Swinomish tribe in Washington state. …

“Using a unique model based on an indigenous worldview, the tribe updated its adaptation strategy in 2014 with environmental, cultural, and human health impact data. It now views health on a familial and community scale, and includes the natural environment and the spiritual realm, said Jamie Donatuto, Swinomish community and environmental health analyst.”

Will government support for tribes’ efforts continue? Read more here.

On the principle that “one and one and 50 make a million,” a better world relies on everybody pitching in. Ordinary people can help scientists and other leaders of worthy initiatives.

Lisa Mullins and Lynn Jolicoeur report at WBUR on one example.

“It’s a cloudy, cool July morning, and we’ve come to the docks at Fairhaven Shipyard, near New Bedford, to meet Chris Parks. She’s a tall, elegant, retired Boston banker in jeans and a sweatshirt.

“Parks is a volunteer with the Buzzards Bay Coalition. Residents formed the group 30 years ago to help the struggling bay.

“She’s got a plastic bottle attached to a long metal pole. She submerges it and fills it with sea water. Then she pulls out her tool box full of vials and chemicals. She mixes and measures.

“Parks determines the water is pretty cool on this day — 67 degrees. … In addition to temperature and clarity, Parks tests the water for how much salt and oxygen are in it. She’s been coming to this dock, fastidiously, one or two mornings a week for 17 years.

” ‘I’m doing it because it’s one of the few things that I can do that is a tangible task towards helping the environment,’ Parks says. ‘It’s a little bit of science that helps tell us what’s going on in Buzzards Bay.’

“What’s going on is that the water is warming — and that may be contributing to long-lasting pollution problems in the bay.”

Buzzards Bay Coalition science director Rachel Jakuba says, ” ‘If you have too much algae in the water, that’s when you get cloudy, murky water, loss of eel grass, low oxygen levels that make it hard for fish and shellfish to survive … Bay scallops are very rare now because part of their life cycle depends on eel grass blades.’

“The Buzzards Bay Coalition is attacking that pollution aggressively. It’s working with homeowners to upgrade their septic systems with technology that reduces nitrogen. …

“Jakuba says as researchers figure out how global warming fits into the bay pollution picture, citizen scientists will be key.

“Mark Sweitzer, 68, is a citizen scientist and lobsterman based at Point Judith in Galilee, Rhode Island. …

“Six times a month while he’s catching lobster, Sweitzer lowers a device to the bottom of the ocean — about 200 feet. It tracks the temperature and other characteristics of the water at every depth, and it syncs the data to an iPad on board. …

” ‘I’m just happy to do it, because I feel like I’m providing some information — even though it might not have immediate effect on my boat, but in long-term trends in the fishery and how it might influence policy or regulations,’ Sweitzer says. …’

” The settlers — the tiny little ones that are four days old that have reached the bottom — there is a temperature at which they will not survive … and there are temperatures at which we have an influx of fish. Black sea bass used to be primarily a mid-Atlantic fish. And now … the black sea bass are down there gobbling up these little lobsters that don’t have much of a chance to make it in the first place.’ ”

Read how other fishermen are noticing ocean changes before scientists do and reporting back, here.

We have a friend who sets lobster pots off New Shoreham, Rhode Island. His catch has gone down steadily over the past few years, so I know there is a problem.

A sign warns residents of the arctic Svalbard islands in Norway of the danger from roaming polar bears. Norway is planning to expand its oil operations in the Arctic. 

Norway has a reputation for environmentalism. Unless you are talking about oil. Now some of the country’s leading lights are suing the government because of its plans to start drilling in the Arctic. A Norwegian whose writing I admire is one of them.

David Crouch reports at the Guardian, “Norway’s best-known author has lashed out at ‘the shortsightedness and stupidity’ of plans to expand oil exploration into the Arctic, as campaigners prepare to sue the government for placing future generations at risk from climate change.

“Karl Ove Knausgaard, whose bestselling memoir has been a global literary sensation, is fronting a campaign to mount a legal challenge against moves by Norway to open up the Arctic to oil companies.

“Oil and gas extraction in the Arctic has nothing to do with worthwhile goals such as alleviating poverty, Knausgaard said. ‘Norway is one of the richest countries in the world – it’s all about greed. … I never believed that my government actually would do such a thing. … It just makes me want to cry.’ …

“The campaign aims to make use of a recent change to the constitution which obligates the state to take action to ensure natural resources are managed ‘on the basis of comprehensive long-term considerations,’ including safeguarding the environment for future generations. …

“The campaign by Norwegian environmentalists aims to mirror similar legal challenges in the Netherlands and in the US, where lawsuits have attempted to hold governments to account over climate change. In April, the Dutch Urgenda foundation launched the first case in the world to use human rights and tort law to hold a government responsible for failing to reduce carbon emissions fast enough.

“ ‘Where do we draw the line if not in the Arctic?’ said Åsne Seierstad, the bestselling Norwegian author and another signatory to the petition. ‘No economic policy is more short-term than relying on profits from the very areas that are worst affected from climate change.’ ”

Plant physiologist Joe-Ann McCoy extracts seeds from black cohosh collected in western North Carolina.

A plant physiologist, worried about the future effects of global warming on biodiversity in Appalachia, is not only preserving seeds but working to attract preservation-based economic development. It would be almost like getting a sponsor for one of the plants there, a plant whose roots are used in popular herbal remedies.

At Yale Environment 360, Nancy Averett writes, “When she can spare the time — away from the grant applications, journal articles, and economic reports strewn across her desk — plant physiologist Joe-Ann McCoy laces up her hiking boots and heads to the Pisgah National Forest in western North Carolina.

“Dodging copperheads and black bears, she winds her way deep into the forest, her eyes scanning the lush understory for black cohosh, a native plant whose roots have been used in herbal remedies for centuries, primarily to treat symptoms related to menopause. When she spots her quarry, McCoy gently pulls the plant’s seed pods — tiny brown orbs that rattle when shaken — off the stem and slips them into a paper envelope.

“The seeds inside those pods — which will be cleaned, vacuum-packed, and then stored in a freezer at -20 degrees Fahrenheit — give McCoy hope. As the director of the North Carolina Arboretum’s Germplasm Repository, her job is to preserve native seeds in this highly biodiverse area in southern Appalachia before climate change makes it impossible for some native vegetation to survive there.

“But the black cohosh holds another promise, as well. The plant’s roots are used in top-selling herbal remedies, and, if someone could succeed in growing black cohosh as a crop and manufacturing supplements here [it] could help drive economic development in this job-scarce region. …

“North Carolina [is] special in terms of biodiversity. Studies have documented more than 4,000 species of plants, 2,000 species of fungi, and 500 species of mosses and lichens in the region. Unlike much of the U.S. East Coast, during the last three ice ages the ground in this region did not freeze, which means the plants here have a much longer genetic history and more diversity than in other areas.

‘If I had to pick one place in the entire U.S. for this project,’ McCoy says, ‘it would be here. This is the ultimate spot.’ …

“When she first came to the arboretum, she focused on black cohosh and creating a robust seed collection from the plant’s entire geographic range — she has 22 different strains — and then growing plants from each strain so she would have enough seeds to back up her collection in three different repositories. These include two federal storage sites — in Ames, Iowa and Fort Collins, Colo. — plus the Svalbard Global Seed Vault in Norway.”

After cataloging the seeds, McCoy turns her attention to the economic possibilities. Read here about her work with investors. The Yale article also describes her ginseng efforts and her assistance to Cherokees who value plants used in traditional medicine.

What is it about Nordic countries that they seem to find more solutions to global challenges than the rest of us? Do they have fewer challenges to worry them, better education, more ability to focus?

Here are some of their successful and replicable tactics for combating global warming.

Christian Bjørnæs writes at Cicero, “By scaling up just 15 proven Nordic solutions, countries all over the world can save 4 [gigatons] of emissions every year by 2030, which is as much as the EU produces today. The costs for this scale-up equal the amount spent in just 9 days on fossil fuel subsidies.

“These results come from the Nordic Green to Scale study which was launched during the UN Climate Conference in Marrakech. …

“ ‘The main concern decision makers have is that it’s either too difficult or too expensive to rapidly reduce emissions,’ says Senior Advisor Oras Tynkkynen, who led the Nordic Green to Scale analysis on behalf of [the Finnish Innovation Fund Sitra].

“ ‘Our objective with this study is to highlight what different countries have already achieved on climate action and what other countries can learn from their successes.’ …

“Urban Danes cycle on an average almost 3 km every day. If other countries followed the example of Denmark and promoted cycling in cities, it would reduce emissions by almost as much as Slovakia produces in a year.

“In Finland, most of industrial and district heating is provided with energy efficient combined heat and power production (CHP). If other countries used CHP like this, it would reduce emissions by almost as much as Japan produces in a year.

“Iceland produces almost 30% of its electricity and most of its heat with geothermal energy. If countries with significant geothermal potential started using it like Iceland does, it would reduce emissions by more than Denmark produces in a year.

“Last year, almost every fourth new car sold in Norway was an electric or plug-in hybrid vehicle. If other wealthy countries used as many electric vehicles as Norway does, it would reduce emissions by almost as much as Denmark produces in a year.

“Sweden has the world’s highest number of heat pumps per population. Scaling up the solution to selected European countries would cut emissions by as much as Cuba produces every year.

“In addition to direct emission reductions, the 15 solutions also create considerable co-benefits. These include improved air and water quality, higher energy security, more local jobs, lower fuel bills, less traffic jams, and sustained biodiversity.”

As costs come down, solar and wind energy are being embraced in interesting places. Stereotypes about Texas and Big Oil will have to go.

Matthew Rozsa reports at Salon, “The notion that Texas might become a hub for renewable energy innovation isn’t that new. As Forbes noted earlier this month, Texas — which produces 37 percent of America’s crude oil and 28 percent of its natural gas — has more than 10,000 wind turbines, allowing it to produce more power from wind than the combined power produced by 25 other states from all energy sources.

“Similarly, The Wall Street Journal reported [in 2015] that Texas expects more than 10,000 megawatts of solar-generating capacity to be installed across the state by 2029, which is almost the size of all the operational solar farms in the United States today.”

Rozsa quotes Texans who were interviewed by Voice of America in October:

“ ‘A lot of wind companies have evolved to include solar and wind because solar has become so cheap. It is quite competitive with not only wind, but with fossil [fuel] generation,’ said Andy Bowman, chairman of Pioneer Green Energy.

“This point of view was echoed by Jennifer Ronk, a renewable energy expert at the Houston Advanced Research Center. ‘There is a lot of research being done, a lot of development being done,’ she argued. … ‘I think there is a mix of solutions that are going to be the optimal outcome.’ ”

I’m pretty sure that cost factors will ensure the continuation of renewable-energy research — if only at the state level.

Is the neighborhood of the future going to be on the water? A growing number of architects around the world seem to think so.

Eleanor Ross and Laura Paddison write at the Guardian about some pluses and minuses.

“Architects and city planners across the world are starting to look beyond the traditional confines of the city, towards building on water as one of the answers to reducing inner-city population density and also developing flood-resilient designs. Global damage to cities from flooding could amount to $1tn a year by 2050 if no action is taken, according to a World Bank report. …

“Building on water isn’t straightforward, however. The recent collapse of the Makoko Floating School in Lagos, one of the most famous examples of floating architecture, shows some of the complexities. …

“There are also environmental concerns. The need for foundations of many floating buildings to go deep into the river bed, for example, will have an impact on the environment, says Phillip Mills, director of the Policy Consulting Network, and a specialist in water construction.

“ ‘Foundations or structures within the river could also alter the river bed with silt erosion and deposition elsewhere in the river. The same thing already happens around bridge piers,’ he says. …

“However, Lucy Bullivant, adjunct professor of history and theory of urban design at Syracuse University, thinks there are greater environmental consequences building on land – such as the tendency to be more car focused – than on rivers. ‘Floating designs will create a good anchor point for plants to help foster biodiversity and create habitats for fish and birds.’

“Building on ‘bluefield’ sights can be environmentally friendly, according to Mark Junak, director of Floating Homes. He says floating structures such as those at Noorderhaven in the Netherlands have recently been subject to underwater drone surveys to observe whether their construction has negatively affected the ecosystem.

“According to the research project, the underwater footage ‘revealed the existence of a dynamic and diverse aquatic habitat in the vicinity of these structures, showing that floating structures can have a positive effect on the aquatic environment.’

“For London architect Carl Turner, who has designed a pre-fabricated, open-source amphibious house specifically designed to float on floodwater, called the Floating House, climate change means needing to work with water.

“ ‘You either protect the house or protect the land,’ he says. ‘Creating large-scale flood protection zones is expensive and in itself potentially harmful to the environment. Once breached, homes are left defenceless, as opposed to floating homes that can simply rise with flood waters.’ ”

Small tree farms are now eligible to sell carbon credits, which can supplement or even replace logging income. But to many owners, getting into the market looks pretty daunting. In a recent article in the New York Times, Erica Goode explains how the obstacles can be overcome.

“Lately, [Eve] Lonnquist, 59 and recently retired, has been thinking about the future of her family’s land. Like many small-forest owners, they draw some income from logging and would like to keep doing so. But they would also like to see the forest, with its stands of Douglas fir, alder and cherry, protected from clear-cutting or being sold off to developers.

“ ‘For us, the property is our family’s history,’ she said.

“More than half of the 751 million acres of forestland in the United States are privately owned, most by people like Ms. Lonnquist, with holdings of 1,000 acres or less. These family forests, environmental groups argue, represent a large, untapped resource for combating the effects of climate change.

“Conserving the trees and profiting from them might seem incompatible. But Ms. Lonnquist is hoping to do both by capitalizing on the forest’s ability to clean the air, turning the carbon stored in the forest into credits that can then be sold to polluters who want or need to offset their carbon footprints.

“ ‘Trees are the No. 1 way in which carbon can be removed from the atmosphere and stored in vegetation over the long term,’ said Brian Kittler, the western regional office director for the Pinchot Institute for Conservation, which has a program in Oregon to help the owners of family forests develop potentially profitable carbon projects. …

“The carbon credits from Ms. Lonnquist’s forest could bring an estimated $235,000 over the first six years, and about $6,000 a year after that, said Kyle Holland, the managing director of Ecological Carbon Offset Partners, a California firm that helps small-forest owners enter the carbon markets. …

“Recent developments in forestry may help make the prospect more appealing by lowering the initial costs to landholders. Mr. Holland’s company, for example, has developed a digital tool — a smartphone equipped with a laser to measure distance and an inclinometer to measure height — that he believes will greatly reduce the expense of conducting a forest inventory, which typically costs $40,000 to $100,000 or more, depending about the amount of land.

“With the specialized smartphone, landholders can take an inventory themselves, photographing and measuring the diameters and heights of their trees. The photos and data are sent to the company’s office in California, where an expert forester goes through the images, identifying the species and checking for damage to the branches or crowns, among other things. Probability models are used to calculate the amount of carbon stored in the forest.”

Hmmm. I wonder if this smartphone app could also be used by towns like Arlington, where John and other volunteers are conducting a tree inventory, not for selling carbon credits but for beautification plans.

Reversing desertification in Africa has to be one of the biggest challenges ever attempted. But if we believe that the longest journey starts with a single step, then the continent’s long journey is off to a good start.

According to the Economist, “Building a wall of trees across the width of Africa is a tall order. Solving the twin problems of land degradation and desertification poses a greater challenge still. But more than 60 years after it was first proposed, just such a project is underway at the edge of the Sahara. …

“In 1952 Richard St Barbe Baker, a British environmental scientist, proposed planting a swathe of trees across the southern reaches of the Sahara. The trees would block the wind and sand that move southward from the desert and improve the quality of the soil by binding sediment together and adding nutrients to the mix.

“Although Mr Baker was unable to convince others of his plan during his lifetime, the idea has since taken root. In 2005, Olusegun Obasanjo, then president of Nigeria, revisited Mr Baker’s proposition, seeing in it an answer to some of the social, economic and environmental problems afflicting the Sahel-Sahara region.

“An estimated 83% of rural sub-Saharan Africans are dependent on the region’s land for their livelihoods, but 40% of it is degraded—worn away by soil erosion, human activity and scorching temperatures—leaving much of it unfit for use.

“In 2007, Mr Obasanjo gained the support of the African Union. The Great Green Wall Initiative was launched the same year. Today some 21 African countries are involved in the project, which has grown in scope. Trees have been planted, but building a wall of them is no longer the priority.

“Instead, the wall of trees has become a vehicle for a wider goal: countries in the region working together to tackle climate change, food security and economic growth. Recent projects include abating soil erosion and improving water management in Nigeria, agri-business development in Senegal and forestry management in Mali.”
