“If lightning is the anger of the gods, then the gods are concerned mostly about trees”*…
Mostly, but not entirely. Chloe Aridjis on survivors of lightning strikes…
There are three types of lightning: cloud to cloud, or intercloud, which leaps across gaps of clear air; intracloud, which doesn’t leave the cloud at all; and cloud to ground, the most threatening: a stream, or rather a meeting of two streams, of ionised particles, each following its own determined course, one towards the heavens, the other towards earth, and where they meet the air crackles with heat, creating a sky of forking paths.
To the attendees of the International Lightning Strike Survivor Conference, who have all had encounters with the third kind, the oft-mentioned statistic (nine out of ten survive) offers little consolation. Many of them, given the consequences, would prefer to have been struck dead. Survival provides small solace when your entire existence has been electrically altered.
Just as lightning isn’t a single event but rather a sequence of strokes, so the memory of a lightning strike returns in fierce, dramatic bolts rather than as one clear picture.
…
Distinguished ornithologist ALEX COSTA from Tampa, Florida, the lightning state (three times more strikes than any other in the US), was observing a rare migratory bird when struck, and when he returned to his senses the bird had vanished along with his shoes, binoculars and long-term memory. Indoor landscape painting (he rarely leaves home) has replaced ornithology and, with his good hand, he now paints imaginary woods and meadows. He doesn’t sleep much at night but reads and takes long naps in his armchair by the window….

As we take cover, we might remember that it was on this date in 1864 that a train running from Cincinnati to Chicago was derailed by a tornado in Dearborn County, Indiana (about 75 miles southeast of Indianapolis). Three passenger cars were lifted from the tracks and dropped in a ravine, injuring 30 people.

As we size up scale, we might recall that it was on this date (the feast day of St. Mary Magdalene) in 1342, that Central Europe’s worst flood ever occurred. Following the passage of a Genoa low, the rivers Rhine, Moselle, Main, Danube, Weser, Werra, Unstrut, Elbe, Vltava, and their tributaries inundated large areas. Many towns such as Cologne, Mainz, Frankfurt am Main, Würzburg, Regensburg, Passau, and Vienna were seriously damaged, with water levels exceeding those of the 2002 European floods. Even the river Eider north of Hamburg flooded the surrounding land; indeed, the affected area extended to Carinthia and northern Italy.

A new database shows 1,500 US lobbyists working for fossil-fuel firms while representing green groups and other with similarly contradictory concerns…
More than 1,500 lobbyists in the US are working on behalf of fossil-fuel companies while at the same time representing hundreds of liberal-run cities, universities, technology companies and environmental groups that say they are tackling the climate crisis, the Guardian can reveal.
Lobbyists for oil, gas and coal interests are also employed by a vast sweep of institutions, ranging from the city governments of Los Angeles, Chicago and Philadelphia; tech giants such as Apple and Google; more than 150 universities; some of the country’s leading environmental groups – and even ski resorts seeing their snow melted by global heating.
The breadth of fossil fuel lobbyists’ work for other clients is captured in a new database of their lobbying interests which was published online on Wednesday.
It shows the reach of state-level fossil fuel lobbyists into almost every aspect of American life, spanning local governments, large corporations, cultural institutions such as museums and film festivals, and advocacy groups, grouping together clients with starkly contradictory aims…

As we contemplate conflicts (and note that last Monday’s, then Tuesday’s “hottest day ever” records are sure to continue to be broken), we might spare a thought for Jacob Bjerknes; he died on this date in 1975. Son of Vilhelm Bjerknes, one of the pioneers of modern weather forecasting, Jacob is remembered for his seminal paper on the dynamics of the polar front, the mechanism for north-south heat transport, and for his contributions to the understanding of the weather phenomenon El Niño.
“Hurricane season brings a humbling reminder that, despite our technologies, most of nature remains unpredictable”*…
Still, as Katarina Zimmer explains, an emerging science can help us improve our forecasts…
… contemporary simulations suggest the Great Colonial Hurricane was a Category 3.5 storm, probably the strongest in recorded eastern New England history. (For reference, Sandy, which killed nearly 150 people and caused some $65 billion in damage in the United States, was technically no longer even a hurricane when it made landfall in the New York metro area in 2012.)
Scientists know about the Great Colonial Hurricane’s impact not only from written reports but curiously, also from hidden, physical impressions the long-ago storm left on the landscape.
At the bottom of a pond, Jeffrey Donnelly, a hurricane scientist at the Woods Hole Oceanographic Institution, and his colleagues found subtle, buried evidence of the storm that almost felled the Mather line. The researchers were collecting sediment cores from a lakebed on Cape Cod. The spot, known as Salt Pond, lies about a third of a mile from the ocean and has long been a place of mud. But in their core samples, they found a pinky finger-thick layer of pure ocean sand in layers that dated back to roughly 1635. The only thing that could have pulled that much beach material over the sand barrier and that far inland was a truly massive storm.
The cores revealed other clues, too. Although written accounts suggest the 1635 tempest was the strongest of its time, the exhumed samples showed it wasn’t the only intense storm in the area. Donnelly found evidence for 10 major storms in the area between 1400 and 1675—a surprising toll, given that major hurricanes are virtually unheard of this far north today. The fact that hurricanes were much more frequent in the past begs the question of why, and whether these levels of storm activity could someday return.
Which is why researchers like Donnelly are traipsing along coastlines and digging in the muck. They hope their relatively new branch of science, paleotempestology (the study of old storms), can use these buried traces of long-gone winds to augur ancient patterns. Patterns that might also help us predict the weather that lies ahead…
Paleotempestology promises to uncover patterns of historical hurricanes—to better predict destructive weather of the future. More at: “The Secret Messages in Ancient Storms,” (or here) from @katarinazimmer in @NautilusMag.

As we muse on the meteorological, we might send exploratory birthday greetings to Bernard Brunhes; he was born on this date in 1867. A geophysicist, he is known for his pioneering work in paleomagnetism, in particular, his 1906 discovery of geomagnetic reversal [see here]. The current period of normal polarity, Brunhes Chron, and the Brunhes–Matuyama reversal are named for him.
Brunes made his discovery in a way that presaged the work of paleotempestologists: he found volcanic lava and clay samples that recorded the Earth’s inversion of its magnetic field.

Despite more than 150 years’ worth of study and experimentation, no one really knows why ice is slippery….
Nineteenth-century Americans used ice to store perishable foods in amounts that astounded visitors from Europe, where an ice trade had yet to be developed. Apples, for example, became so commonplace in the young republic that visitors coined the phrase “as American as apple pie.”…
By WWII, the burgeoning industry of electric refrigeration was catching up to the ice industry, and companies like the Southland Ice Company were forced to rethink their business plans. Southland began selling kitchen staples like milk and bread alongside their ice. The combination became so popular, the company extended its hours to keep up with demand, and within a few years renamed itself after its new hours of operation. The 7-Eleven was born, and convenience stores today still sell ice…
Between WWII and 1975, the amount of electricity refrigerators consumed grew by more than 350 percent. Today, a look at energy use around the globe reveals that the cooling industry (refrigerators, freezers, and air conditioners) accounts for almost 10 percent of all CO2 emissions…

As we chill, we might recall that it was on this date in 1982 that record low temperature of -117 F was recorded in Antarctica. That record was broken the following year, also in Antarctica, at -128.6 F– a mark that stands to this date, as Antartica has been warming… leading Dr. Brady to ask, “in an age of accelerating global warming… can ice in the freezer and ice on our planetary poles continue to coexist?”
