Dry Run

Just when I thought autumn had finally arrived with a two-day rainstorm, the winds changed and summer is back. It’s as dry as ever, and no end in sight. In keeping with this year’s extreme weather, I noticed something different on my running loop.

Earlier this year, after a wet spring, a local meadow was in fine form. This is a stretch of grassland that is used to graze local dairy cattle. It sits between a copse of trees and a local forest, and is divided by a stream that usually goes dry in mid-August.

This year, the stream was already dry in July, despite the spring rains. It fills up briefly if we have a heavy rain, but then dries out again. This is the same meadow in early September.

What’s surprising to me isn’t that the grass is golden and dry. The new thing this year is that the grass has been harvested. In two decades of living here, I’ve never seen the grass harvested for feed. Usually, this meadow is openly grazed until snowfall, and then again as soon as the last frost has passed.

And then I noticed that two other meadows usually left untouched for open grazing had been harvested for grass. In fact, all the meadows surrounding my running loop had been cut down to the ground.

Some of these meadows are on private estate lands, and I’m wondering whether there’s some new local law to harvest grasses? More likely, I think, is that the feed harvest has been so bad this year that the local dairy farmers and horse stables are trying to access any kind of local feed to augment the bad crop yields – after all, the local crops were already fields of dry stalks by early August this year.

The only crop that seems to have done well around here is a field of soy that was flooded in early rains, and has since gone golden. Surprisingly, the soy proved resilient.

So now I’m wondering what kind of impact all this meadow cutting will have on local wildlife that usually depends on having a rich supply of winter grass to use for burrowing, eating, and general merriment. The times, they are a’changing.

After The Rain, Before The Storm

The nightly storms that send rain pelting down upon our humble home and illuminate the sky with lightning are impressive. More surprising though, is waking up every morning to blue skies.

It’s not that we aren’t used to wild weather here in the Lake Geneva region; when you live between two mountain ranges, you expect thunderstorms to rattle the windows and drown out conversation.

Big clouds billow and march, rain and hail burst forth from balmy summer skies, winds change direction on a whim and another ‘orage‘ has made its mark.

As I write this a couple of hours after my run in the sun, clouds are already gathering again, the air getting heavier, the wind picking up. Another storm is on the march.

But the weather we are experiencing isn’t limited to our neighborhood between the Jura and the Alps – half of Europe is counting the high numbers of lightning strikes as if keeping score. France saw almost 150,000 recording lightning strikes in May 2018, the most since the collection of that kind of data began in the early 2000s.

It’s not that we’re having more storms, it’s that the storms are having more of an impact. The average temperature in France for the month of May this year was a full degree Celsius higher than last year. Thunder and lightning storms feed on that kind of heat.

As for the blue skies: At least where I live, every morning over the past week has dawned bright and shiny as a newly minted coin, as if all that noise over the past night belonged to some other country. Birds are singing, the critters are out, as if we’ve all agreed not to speak of the violent winds and rain. A large dragonfly followed me for much of my morning run, always just out of photo range.

Flying ahead, settling, watching me approach, and then flitting off again, further and further away from any pond or river where it might normally live. Of course, the garden flowers are hanging and the glorious peonies of May are lost in aprons of pink petals on the ground.

 

More storms are predicted for the rest of the week…

Vehicular Pollination

A cold winter and a short spring have left a short window for many species of trees and plants to release wind-borne pollen – so they are doing it all at once. It’s an adaptation for them, and we have to adapt. Part of that adaptation, I suppose, is that all of our vehicles are now purveyors of pollen.

I washed the first batch of pollen off my car less than 48 hours before the image here was taken, and my grey car is already completely yellow again. Pollen. Some types of pollen have a remarkable ability to fold in upon themselves for their flight, allowing them to retain moisture, and then unfold upon arrival in a hospitable destination, ready to reproduce. My guess is that the folding pollen types remain folded on the hot roof of my car, waiting for a better home.

This isn’t the first year I’ve seen all the cars turned the same golden color, but it might be one of the most intense. And of course, it’s not just the vehicles. It’s on every possible surface. But then, I don’t generally suffer from hayfever – otherwise, my concerns would be elsewhere.

How many different species of vegetation are represented on the top of my car?

If their pollination season is usually spread over several weeks, and they’ve all released at the same time, what impact does that have on the various animals or plants that interact with them according to a seasonal schedule that has been drastically accelerated?

These are the questions I ask myself as I look out over the dusty hood of my car. Meanwhile, if you are in an area where pollen is carpeting everything, here’s a good article on how to keep those fertile little motes from damaging the paint on your vehicle.

 

 

Earth Day Is Your Day

A few thoughts on what Earth Day means for all of us.

From my window right now, I can see two European magpies exploring my small garden – I mowed the lawn for the first time this year, and I suppose they are scouting for anything interesting that was revealed. The resident flock of sparrows is watching the magpies from the safety of a plum tree, and the cherry tree is casting a soft rain of white petals. I’m inside (for the moment), but that doesn’t make me feel any less a part of the scene just a few yards from where I’m sitting.

I’ve always been puzzled by the notion that caring about what happens to our environment is something humans can choose to do, or not to do. It’s one of our great shortcomings, I think, that so many people and cultures see humans as separate from nature itself; mankind is superior, the apex of creation, the eyes and the brains observing nature as if at arm’s length.

And so we have Earth Day to remind us to think about how important Nature with a capital N is for our well-being. Those who honor or participate in Earth Day also try to remind everyone else that actually, every day is Earth Day. Those who don’t participate might see it as a waste of time for something that doesn’t concern them.

Regardless, we are all profoundly a part of nature – we are just as much a part of nature as a branch is a part of a tree. Nature isn’t ‘out there’ – it’s you and every interaction you have.

In the smallest and in the largest ways, individually and collectively, we are woven into the fabric of what’s around us. And everything we do, from eating to producing waste to reproducing, is a part of that fabric. For better or for worse. While there are certainly many people with few options at their disposal, so many of us think we don’t have the time or energy to make environmental choices – and by doing so, we’ve already made a decision.

This year’s Earth Day theme is reduction of plastic waste – so what are you doing, today and every day, to increase or minimize the tidal wave of plastic that is quite literally suffocating your water supply, polluting the land that grows your food, and infiltrating your fellow creatures?

On Earth Day, which I feel obligated to say is actually every day, what are you, a part of nature, doing to impact the rest of your world?

Lessons in Listening

For the first time in its 59-year history, the Australian Science Teachers Association’s (STAWA) Secondary School of the Year award, an annual prize handed out in Western Australia, went to a school outside of Perth. That kind of anomaly deserves a second look.

The school that won the award for science research is the Christian Aboriginal Parent-directed (CAPS) school in Coolgardie, an independent school established by Aboriginal parents who felt the quality of education in their region was lacking.  This was also the first time the STAWA award went to a school with a mainly Aboriginal student population.

The students at CAPS were under the tutelage of a young science teacher from the United States, Allan Alipio, who wanted to inspire students with the passion he himself felt for science. He allows the students to come up with some of their own ideas, and this is where I think the story starts to get really interesting.

The projects that won the award were mostly based on the application of native plants and indigenous knowledge to energy and medical experiments. One group of teens investigated the antimicrobial potential of traditional medicine plants maroon and crimson turkey bushes as well as sweet potato leaves for potential use as an anti-diarrhoea medication, while another group used local plants like wheel cactus and gum leaves to make ethanol.

This award speaks to the profound impact that good teaching can have – not just on passing along the facts and passing tests, but on inspiration and passion. I think it’s important to stress that, rather than imposing a standardized curriculum, Mr. Alipio listened to his students.

There’s a lot that could be discussed here about the all-too-common lack of education funding for indigenous populations. This gets at a larger issue of the side-lining (or worse) of indigenous populations around the world, and the extent to which their deep local knowledge has been suppressed, disdained, ignored, or (as with many medicinal applications) commercially exploited. And as we slog through this new era of climate change, that knowledge is more relevant than ever – as is the necessity to start listening.

People who identify as indigenous number an estimated 370 people worldwide, made up of around 5000 groups across 70 countries. They make up approximately 5% of the global population – but traditional lands and territories contain an estimated 80% of Earth’s biodiversity.

Gleb Raygorodetsky put it well in this excellent article: “With collective knowledge of the land, sky and sea, these peoples are excellent observers and interpreters of change in the environment. The ensuing community-based and collectively-held knowledge offers valuable insights, complementing scientific data with chronological and landscape-specific precision and detail that is critical for verifying climate models and evaluating climate change scenarios developed by scientists at much broader spatial and temporal scale. Moreover, indigenous knowledge provides a crucial foundation for community-based adaptation and mitigation actions…

The difference in world views can be as fundamental as the botanical illustrations of plants above done through Western eyes, the illustration of bush plants below done by Aboriginal artist Gloria Petyarre.

I will get into huge topic around the overlap of human rights issues, indigenous peoples and environment another time, but for the moment, I would say this: As long as that deep knowledge stays on a parallel but separate track from Western-based science, policy, legislation and education, we are missing out on critical opportunities to learn and adapt to the changes we have created over a relatively short period of time. At the same time, learning to listen and to cooperate puts people back in the loop when it comes to determining the fate of the land on which they live – and might just help us weather the approaching storm.

Hopefully, students like the award-winning teens at CAPS will be able to leverage knowledge from both worlds to help chart a path ahead.

It’s A Hot One

The little digital thermometer on my window here in south-eastern France read 50.1°C (122.2°F) yesterday. Today it’s even higher.

55.3°C (131.5°F). I definitely need to move this device. The actual temperature is 32°C (89.6°F).

Not that the outside air is really that hot. It’s just the sun heating the glass of the window to that searing temperature. Until I get around to moving the thermometer to a location that offers more accuracy, there’s not much point in panicking about the numbers on the display.

Still, according to Meteo Swiss, yesterday was the hottest day of the year so far in our region, 35.5°C (95.9°F). These days, the announcements of monthly, yearly or all-time heat records being broken beat down with the worrying regularity of a leaky faucet.

It’s not just a subjective feeling that the summers are getting hotter and drier, the winters shorter and warmer. When we moved to this area of high mountains and lakes, winter meant thigh-deep snow at least three times per season. Now it’s knee-deep once a year. And summers?

Hm. Let me go have a look at that thermometer again.

There’s a pretty video making the rounds this week, a striking representation of temperature anamolies over the past hundred years or so, broken down by country.

It starts off as a rayed sphere of blue, yellow and orange, showing average highs and lows above a baseline. By 2000, it’s a pulsing sun of spiky red lines.

Antti Lipponen, a researcher at the Finnish Meteorological Institute, created the visual using publicly available data from NASA earth sciences programs. These are the very programs that have had their budgets cut by 9% under the new U.S. administration, in favor of planetary science programs.

Unlike my window thermometer, this climate data is accurate. Ignoring it won’t make the raw information change, and it won’t change the fact that anyone and everyone with the means needs to act now to make Lipponen’s visual – and our planet – stay in the safety zone.

Cartography of Extremes

Maybe it’s the instinctual part of humans that makes us obsessed with the biggest, the strongest, the highest, the illustrious measurements that dazzle. Whether it’s the highest mountain, the broadest lake, the longest river, we look for inspiration in extremes.

Whether it’s justified or not, we do the same in societies. The biggest economies, the loudest voices, the heaviest sticks get all the attention. The heavyweight nations win the privilege of gathering together and trying to coordinate the world’s economy and, to a certain extent, its immediate future. To the extent that it’s possible during a few short days, a summit like the G20 in Hamburg promises an opportunity for representatives from the largest 19 economies, plus the European Union, to sit down together and talk about the world.

A cartography of the G20 might look a bit like this map from 1849, all the biggest players in the same place, at the same time, a landscape of superlatives.

This Group of 20 nations holds 85% of global GDP, 80% of world trade, and 75% of the world’s population. Chancellor Angela Merkel, head of host country Germany, has promised to put climate change at the top of the agenda as the world’s most pressing issue. In response to the United States leaving the Paris Agreement, she stated, “We cannot wait until every last person on earth has been convinced of the scientific proof.”

But what does that mean? The countries most impacted by climate change, by and large, are not the largest economies, and are not present at the G20. The countries that are at the G20, by are large, are the large economies which – through industrialization, consumer and disposable economies and resource exploitation – are the main contributors to climate change in the first place – and likely ones that will have to contend with climate-based migration.

Even if they’re all in the same room and have the best intentions, are they the top team to undertake wrenching challenges to institutions and economic assumptions in order to avoid further temperature and sea rises? After all, the G20 was created in 1999 to promote global economic stability, not to promote radical restructuring.

Because as we’re seeing with every passing year, there all kinds of new extremes to be charted, and we’ll need everyone at the table to navigate them.

Heating Up, Cooling Off

It’s a paradox of life that what gives us pleasure in moderation often gets us into trouble when we get greedy.

I’m not talking about food, alcohol, cigarettes, chocolate, or any of the other things that might come to mind. Because the second-highest heat index ever recorded in a city was marked today in Bandar Mahshahr, Iran – a mix of high humidity and soaring air temperatures yielded a ‘feels-like’ of 74°C (165°F).

So I’m talking about air conditioning.

Modern air conditioning, the kind that transforms vast stretches of hot agricultural land into productive cities with office buildings and booming economies, was only invented in 1902. Before that, the height of technology when it came to cooling was the rotary fan, which was used as far back as the 2nd century in China (only for the very wealthy).

So what’s the paradox with air conditioning? Well, there are a few. For one thing, that delicious cool air comes at a price. It’s considerably more expensive than your average table or ceiling fan when it comes to electricity, because it needs a lot more power. A ceiling fan uses 25 to 90 watts of energy; central air conditioners can use as much as 2500 to 3500 watts. Even with increasing efficiency in AC units, and the expansion of renewable power generation, AC is still an energy intensive alternative.

And then there are the ozone-depleting refrigerants. CFCs, HCFCs and HFCs used for cooling are all greenhouse gases. The worst of the coolants have been banned in western countries (starting in the 1980s with the Montreal Protocol*). HFCs were banned in a 2016 treaty signed in Kigali, Rwanda, with phase-out starting in 2019 in the United States and then gradually for other countries, notably China (2024) and India (2028).

Meanwhile, AC use is rising rapidly in these countries as the middle class expands. Berkeley National Laboratory estimates that about 1.6 billion new air-conditioning units will be installed by 2050. It’s almost like we’ve forgotten that we went for millennia without it, or have architectural techniques for coping with heat without AC – methods both ancient and new.

The more we use air conditioning, the hotter we make the planet, and the more we need air conditioning.

So get out your hand fan, crank up your ceiling fan (or in my case, table fan), and get ready for the next heat wave.

*Reagan signed the Montreal agreement with the words, “The Montreal protocol is a model of cooperation. (It) is the result of an extraordinary process of scientific study, negotiations among representatives of the business and environmental communities, and international diplomacy. It is a monumental achievement.”

Although President Donald Trump removed the U.S. from the Paris Agreement, there is little worry he will do the same for the HFC agreement – the phase-out is supported by the two U.S chemical companies that make HFC alternatives, the DuPont spinoff Chemours and Honeywell International.

 

Abundance of Sun

June 21 marks the longest day of this year in the northern hemisphere, and thus, it’s officially summer. Happy Summer Solstice!

At least here in south-eastern France, the dog days have already begun – hot and sunny and cloudless and dry.

We’re in the midst of the year’s first proper heat wave, with the temperatures at near-record highs. There’s the sense that every year now, or at least most of them, will be record-breaking when it comes to heat.

We hooked up cisterns to catch spring’s ample rainfall – with any luck, that water will see the kitchen garden through what promises to be a very long season of sun spread over ever-shortening days.

 

 

Six of One

I have an affinity for hybrids of technology and nature, whether in art or engineering. There was the Coniferous Clock made of cedar, fresh and green in spring, brown and withered in winter, that told a simple tale of a year’s passing.

Here’s a new take on using plants in a sleek design: The CityTree, made by Green City Solutions. CityTree is an urban air filter that uses moss to remove pollutants from city air.

In a cool trick of using densely packed moss that has more leaf surface area than other plants, the self-contained, mobile units are solar-powered, self-watering and are monitored via sophisticated sensors. They are estimated to remove the same amount of pollutants from city air as up to 275 trees. This can, according to the inventors, add up to the annual removal of 240 metric tons of CO2 per unit.

Like the super neat SmartFlower Solar installations of blossom-shaped solar panels that follow the arc of the sun across the sky – one is at a supermarket just down the road from our house – this is a great concept that has its price. In the case of CityTree, each unit is currently priced at around $25,000. The company states that the units are made from a high proportion of recyclable materials and have a long life, but how does that really break down in terms of resources, disposal, and maintenance over the long term?

Still, I like it. Even if achieving equivalent results doesn’t always mean the methods were equivalent. Six of one isn’t always the same as half a dozen. After all, plant a hundred trees or cover a hundred house walls in ivy, and you’ll be filtering city air for decades with very little overhead. But for that, you need the soil, the water and the will.

It’s a sign of our poor urban planning that we even need to talk about CityTree, but I have a feeling we might just be seeing more of them. The makers boast that CityTree has the services of a whole forest on the surface of 3.5 sq. meters (37 sq. feet).

It’s an intriguing and creative solution. They’re nice to look at, and I bet they smell almost like a forest.
