“The beaver told the rabbit as they stared at the Hoover Dam: No, I didn’t build it myself, but it’s based on an idea of mine”*…

Of all the things that humanity builds from concrete or stone, there are few structures that influence the surface of Earth quite as profoundly as a dam.

By blocking the flow of a river, we dare to defy gravity’s pull on water from mountain to estuary – and influence the trajectory of geology itself. A dam does so much more than submerge a valley to create a reservoir: it transforms a river’s natural course, accruing silt and sediment at an artificial barrier, and dampening water’s erosional force downstream

Their vertiginous walls, striking shapes and deep foundations will also leave a unique archaeological imprint. Some of these engineered monoliths are so enormous that they may be preserved for millennia.

Meanwhile, dams can also bring deep changes for the people who live nearby, and the generations that follow them. When a government in a distant capital decides to exploit its rivers, destruction of local homes, farmland and livelihoods often follows. For example, while the rest of the world focused on Covid-19 earlier this year, an entire ancient town in Turkey was lost to rising reservoir waters. Long after we are gone, future archaeologists will study such submerged settlements and may wonder why we let them go for the sake of short-term politics and energy demand.

The effects can be felt a long way from home, too. Damming rivers that wind through continents, like the Nile in Africa, can withhold valuable water and power from countries downstream, forever changing the trajectories of those nations…

Few human structures can change a landscape quite like a dam– a pictorial essay: “How dams have reshaped our planet.”

As we interrogate interruption, we might recall that it was on this date in 1570 that the All Saints Flood broke dikes and overwhelmed the Dutch (and parts of the German) coast. At least 20,000 people were drowned and many times that many left homeless; livestock was lost in huge numbers; and winter stocks of food and fodder were destroyed. In Zeeland the small islands Wulpen, Koezand, Cadzand, and Stuivezand were permanently lost.

“Disasters are called natural, as if nature were the executioner and not the victim”*…

 

The United States is an enormous country, spanning mountains, deserts, forests, prairie, tundra, and more. This varied terrain is also home to many natural hazards spawned by air, water, fire, and forces beneath the Earth’s surface.

Some of these threats are dramatic; the United States and its territories have the greatest number of active volcanoes of any country except Indonesia, as well as the most tornadoes. Other hazards, like heat waves, are less flashy but can still kill you.

Different regions of the country face very different hazards. But which part of the United States is the most dangerous? It turns out there’s no simple answer, although the south does have a particularly generous share of hazards…

See how the country’s natural menaces differ by geography at “Where in the United States is nature most likely to kill you?

As we calculate our odds, we might recall that it was on this date in 1899 that New Richmond Tornado– an estimated F5 storm, formed in the early evening, and went on to tear a 45-mile long path of destruction through St. Croix, Polk and Barron counties in west-central Wisconsin, leaving 117 people dead, twice as many injured, and hundreds homeless.  The worst devastation wrought by the tornado was at the city of New Richmond, Wisconsin, which took a direct hit from the storm.  In all, more than $300,000 ($8,825,000 in today’s dollars) in damage was reported.  Still, it ranks as only the ninth deadliest tornado in United States history.

“I don’t do drugs. I am drugs.”*…

 

Drug companies have a problem: they are finding it ever harder to get painkillers through clinical trials. But this isn’t necessarily because the drugs are getting worse. An extensive analysis of trial data has found that responses to sham treatments have become stronger over time, making it harder to prove a drug’s advantage over placebo…

Bad, good, or simply confusing news? Decide for yourself at Nature.

As we take the red pill, we might recall that it was on this date in 1814 that London suffered “The Great Beer Flood Disaster” when the metal bands on an immense vat at Meux’s Horse Shoe Brewery snapped, releasing a tidal wave of 3,555 barrels of Porter (571 tons– more than 1 million pints), which swept away the brewery walls, flooded nearby basements, and collapsed several adjacent tenements. While there were reports of over twenty fatalities resulting from poisoning by the porter fumes or alcohol coma, it appears that the death toll was 8, and those from the destruction caused by the huge wave of beer in the structures surrounding the brewery.

(The U.S. had its own vat mishap in 1919, when a Boston molasses plant suffered similarly-burst bands, creating a heavy wave of molasses moving at a speed of an estimated 35 mph; it killed 21 and injured 150.)

Beware the Pink Armadillo!…

Blizzards across the U.S. (record snowfalls)… droughts in Russia (worst in a century) and China (likely the worst in 200 years)…  a one-two punch in the Antipodes: a century-worst decade of drought in Australia followed immediately by devastating floods

There’s no question that climate disruption (or “global warming” or whatever one wants to call it) is having real impact: disrupted transit and hammered retail sales in the U.S. (and the U.K.) seem mere inconveniences in the face of drought-driven pressure on global food prices– pressure that’s aggravated the already painful problem of poverty around the world, and that’s surely contributed to the tensions roiling repressive/regressive regimes in the Middle East and elsewhere…  all, scientists suggest, just a taste of the broader and deeper impacts to come if humankind doesn’t heal its relationship with Nature.

And, of course, it is up to us humans.  Nature doesn’t care.  Nature is perfectly prepared to get on with a future sans people.  Memento Mori, Memento Natura…

Thankfully, there are artists to remind us– artists who were, as is so often the case, attuned to the threat even before the scientific establishment.  Consider, for example, Jinzo Ningen Kikaida (a 70s Japanese TV series in the tradition of the great Ishiro Honda), which fielded this crystalline allegory:

Mother Nature’s go-go boots are made for walking– walking all over you.

As we ask not what Copenhagen can do for us, but what we can do for Copenhagen, we might recall that it was on this date in 1611 that Johannes Fabricius discovered sunspots (now reputed to have some impact on global climate); he published his observation on June 13 of that year in  Narratio de Maculis in Sole Observatis et Apparente Earum cum Sole Conversione (“Narration on Spots Observed on the Sun and their Apparent Rotation with the Sun“).
