“Nature is the source of all true knowledge”*…
Jonathan Keats on why– and how– clocks that use nature to measure time can reintegrate people into the environment and counteract the calamities of the Anthropocene…
In his studio on the east coast of Vancouver Island, the master clockmaker Phil Abernethy is crafting a timepiece that will be calibrated in a manner that no horologist has ever attempted. It won’t show the minutes and hours of an ordinary human day. Instead, his clock will display time as experienced by some of the oldest trees on the planet.
Using techniques he’s honed over a lifetime, Abernethy will machine the gears by hand in traditional materials such as steel and brass. But the pendulum will respond to the forest: When trees grow quickly, the hours will advance more rapidly; more lethargic growth will result in a slower tempo. Over centuries, the long-term fate of the canopy will be registered on a calendar that may deviate from the Gregorian date by decades or more.
Abernethy has been commissioned to fabricate the arboreal clock by the Nevada Museum of Art. Standing 12 feet tall, the clock will be the first physical manifestation of an environmental timekeeping project I have been developing over the past decade. Some of the clocks in the project respond to rivers; Abernethy’s enlists a stand of bristlecone pine trees in Nevada’s Great Basin as living timekeepers.
Fluctuations in the bristlecones’ growth rate, affected by environmental conditions ranging from local rainfall to planetary climate change, will be measured by analyzing the thickness of tree rings in microcores retrieved from the mountain each year. These data will be used to determine the center of gravity for the pendulum, which will swing slower or faster depending on the tree ring thickness. Though the clock face will display time in the usual way, it won’t serve as a mechanism for human planning — a technology to impose order on the environment for our convenience — but rather to pace our lives to match the lived reality of other organisms.
Abernethy’s arboreal clock, in other words, upsets more than just the standards of horology. The environmental calamity known as the Anthropocene is a consequence of a worldview in which all that is not human is construed as a resource — even time itself. Other life forms are going extinct at an unprecedented rate, laid waste at a pace set by the world economy. Factory farming and logging, fossil fuel and plastics production, mining, human construction and infrastructure — all disregard the timing with which nonhuman systems emerge, ebb and flow. The globalized logic of industry, with its planetary supply chain, must keep up with human demand, turning civilization itself into a manifestation of logistics.
Our mastery of the world is a mastery of time. And as every industrialist knows, mastery of time requires the precision of a master clock to provide a temporal standard against which everything can be measured and controlled. Whether regulated by the swing of a pendulum or the oscillations of a strontium atom — as the most advanced atomic clocks are today — the master clock operates without an external feedback mechanism. The clock has become the ultimate authority. To question it would be tantamount to questioning modernity.
The design of Abernethy’s arboreal clock may be novel, but the underlying ideas are ancient. They predate pendulums and gearwork, originating in an era when people observed time in relation to other beings in order for all to flourish together. Ancient but mostly forgotten, these ideas are urgently needed today. Whatever practical use it might have, the arboreal clock is intended primarily to serve as a philosophical instrument…

… Humankind appears to be the only species to have contrived clocks that count without reference to something outside of themselves. We also appear to be the only species to have use for these contraptions, to use time in this peculiar way. (Mumford astutely described clocks as “power machinery whose ‘product’ is seconds and minutes.”)
All life depends on timekeeping. But nonhuman life treats time as a mixed medium: entangled with the environment, dependent on other organisms…

… Near the peak of Mt. Washington in Nevada’s Great Basin, which rises more than 11,600 feet above sea level, the bristlecone pines are as scraggly as the tree in “A Charlie Brown Christmas.” Until very recently, bristlecones didn’t grow at this elevation. To walk down the slope is to stroll through time, eventually reaching trees that are several thousand years old and as solid as sculpted stone.
Over the past decade, I have gotten to know these trees, visiting with members of the Long Now Foundation, the organization that stewards part of the mountaintop and has partnered with me on the clock at the Nevada Museum of Art. By observing the trees and their embodied experience of time, I have been able to see the inadequacy of my wristwatch.
The trees sensitized me to the time reckoning of other life forms, both plants and animals. They attuned me to the time kept collectively in living systems such as rivers, where the flow rate is affected by the melting of glaciers and the eagerness of beavers, not to mention the unquenchable thirst of industrial agriculture. By gearing the flow of time to match the flow of the Susitna or Matanuska — as I have done in partnership with the Anchorage Museum — fluvial clocks can integrate people into local watersheds.
An arboreal clock can likewise integrate people into the forest. Or to be more accurate, it can reintegrate people into their ecosystems, counteracting the human denaturing of the Anthropocene…

As we think about time, we might also contemplate natural space, and spare a thought for Abraham Ortelius; he died on this date in 1598. A cartographer, geographer, and cosmographer, he created the first modern atlas, the Theatrum Orbis Terrarum (Theatre of the World)– “the book that invented the world.”
Ortelius is generally considered one of the founders (with Gemma Frisius and Gerardus Mercator) of the Netherlandish school of cartography and geography. He was an important geographer of Spain during the age of discovery– and the first person proposing that the continents were joined before drifting to their present positions.

Bristlecone pine rings: they are so fine and dense that over a century of life can be embodied in a single inch of wood
The oldest of the living bristlecone pines were saplings when the pyramids were raised. The most ancient, called Methuselah, is estimated to be more than 4,800 years old. As Ross Andersen explains in Aeon, their rings tell tales of climates past… and hold portents of climates to come.
The burning of books and libraries has perhaps fallen out of fashion, but if you look closely, you will find its spirit survives in another distinctly human activity, one as old as civilisation itself: the destruction of forests. Trees and forests are repositories of time; to destroy them is to destroy an irreplaceable record of the Earth’s past. Over this past century of unprecendented deforestation, a tiny cadre of scientists has roamed the world’s remaining woodlands, searching for trees with long memories, trees that promise science a new window into antiquity. To find a tree’s memories, you have to look past its leaves and even its bark; you have to go deep into its trunk, where the chronicles of its long life lie, secreted away like a library’s lost scrolls. This spring, I journeyed to the high, dry mountains of California to visit an ancient forest, a place as dense with history as Alexandria. A place where the heat of a dangerous fire is starting to rise…
Deforestation began in prehistoric times, but it was not always as brutal or efficient as it is today. Our primate ancestors practised a kind of deforestation by migration, trading the treetops for terra firma and the forests for open plains. Humans are a different story. Anthropologists suspect we have been cutting down trees for as long as we have been around, mostly to harvest raw material for shelter and fire, but also to construct crude bridges to cross rivers into new landscapes. For a time, our tree-felling was no match for the regenerative power of forests. Indeed, today’s indigenous forest peoples demonstrate the human capacity to live within a forest’s natural limits. But over the past 5,000-10,000 years, our fast-growing civilisations have developed the technology to clear trees faster than they can grow back. In that short time — a slim fraction of the forests’ tenure on Earth — we have managed to destroy more than half of them. And we are getting better at it…
Mankind’s newest deforestation “tool”– climate change:
In 2005, a researcher from Arizona’s tree-ring lab named Matthew Salzer noticed an unusual trend in the most recent stretch of bristlecone tree rings. Over the past half century, bristlecones near the tree line have grown faster than in any 50-year period of the past 3,700 years, a shift that portends ‘an environmental change unprecedented in millennia,’ according to Salzer. As temperatures along the peaks warm, the bristlecones are fattening up, adding thick rings in every spring season. Initially there was hope that the trend was local to the White Mountains, but Salzer and his colleagues have found the same string of fat rings — the same warming — in three separate bristlecone habitats in the western US. This might sound like good news for the trees, but it most assuredly is not. Indeed, the thick new rings might be a prophecy of sorts, a foretelling of the trees’ extinction…
Over the course of 400 million years, trees built up a fertile new layer on the Earth’s surface, a layer that incubated entirely new ecologies, including those that gave rise to our ancestors. But now it is humans who spread out over the planet, coating its surface in cities and farms, clearing away the very trees that enabled our origins. This forest, like so many others, has become an intersection in time, a place where narratives of geologic grandeur are colliding. A place to put your ear to the ground, a place to confirm that even here, in the most ancient of groves, if you listen closely, you can hear the roar of the coming Anthropocene.

As we ponder pruning our purchases, we might say both hello and goodbye to Sir Thomas Browne; he was born on this date in 1605, and died on this date in 1682. A devout Christian doctor (author of Religio Medici [The Religion of a Physician]), Browne was also a follower of Francis Bacon, an adherent of the Baconian dedication to enquiry, and as a consequence, a keen observer of (and writer about) the natural world… thus an early partisan in what we now call the Scientific Revolution.
