It begins each day at nightfall. As the light disappears, billions of zooplankton, crustaceans and other marine organisms rise to the ocean surface to feed on microscopic algae, returning to the depths at sunrise. The waste from this frenzy – Earth’s largest migration of creatures – sinks to the ocean floor, removing millions of tonnes of carbon from the atmosphere each year.
This activity is one of thousands of natural processes that regulate the Earth’s climate. Together, the planet’s oceans, forests, soils and other natural carbon sinks absorb about half of all human emissions. […]
Findings by an international team of researchers show the amount of carbon absorbed in 2023 by land has temporarily collapsed. The final result was that forest, plants and soil – as a net category – absorbed almost no carbon.
There are warning signs at sea, too. Greenland’s glaciers and Arctic ice sheets are melting faster than expected, which is disrupting the Gulf Stream ocean current and slows the rate at which oceans absorb carbon. For the algae-eating zooplankton, melting sea ice is exposing them to more sunlight – a shift scientists say could keep them in the depths for longer, disrupting the vertical migration that stores carbon on the ocean floor.
A typical lawn sprinkler features various nozzles arranged at angles on a rotating wheel; when water is pumped in, they release jets that cause the wheel to rotate. But what would happen if the water were sucked into the sprinkler instead? In which direction would the wheel turn then, or would it even turn at all? That’s the essence of the “reverse sprinkler” problem that physicists like Richard Feynman, among others, have grappled with since the 1940s. Now, applied mathematicians at New York University think they’ve cracked the conundrum. […]
“We found that the reverse sprinkler spins in the ‘reverse’ or opposite direction when taking in water as it does when ejecting it, and the cause is subtle and surprising.” […] found that the reverse sprinkler rotates a good 50 times slower than a regular sprinkler, but it operates along similar mechanisms, which is surprising. […]
The reverse sprinkler problem is associated with Feynman because he popularized the concept, but it actually dates back to a chapter in Ernst Mach’s 1883 textbook The Science of Mechanics (Die Mechanik in Ihrer Entwicklung Historisch-Kritisch Dargerstellt). Mach’s thought experiment languished in relative obscurity until a group of Princeton University physicists began debating the issue in the 1940s.
As the founder of Ironic, a meteorology company based in Brooklyn, Mr. Leavitt, 33, knows how temperatures and atmospheric conditions can sometimes affect weddings. […] Mr. Leavitt, who said he has conducted weather advisory for more than 2,400 events, now works as a consultant to wedding planners and venues, with fees starting at around $2,500. […]
While we can’t predict if there will be rain that day, what we can do is look at the historical weather data. We look at a specific mile in a location around the country over the past 30 years, and analyze the information. Say it’s rained three out of seven days, five out of seven days or seven out of seven days — that tells you a lot. If you know it’s going to rain five out of seven days, it’s a good idea to find a venue with an indoor option. If it’s raining once out of seven days, you can plan for an outdoor wedding.
We’re tracking every radar possible, every reporting data possible, and creating a clear picture of what the weather will be on a specific day. […] For a wedding in Martha’s Vineyard, Mass., we used marine data to look at the wave height to determine when boats should transport guests for the easiest ride with the most peaceful, calm waters. At what time will people become less seasick? We did it in Lake Como, Italy, too.
For a Florida wedding on the beach, a couple wanted to get married outside in the afternoon, but didn’t want guests to be sitting in direct sunlight or holding up parasols and blocking the view. We produced a sun study — looking at the topography of the land, trees on the property, angle of the sun, height of the house and the sun’s path — to choose the precise time to start the ceremony with the most shade.
As meteorologists, we should never ever suggest what people do with their hair. But we can give you all the information on wind, speed, humidity and temperature, so you can take that to a hair stylist. If someone has naturally frizzy hair in a humid climate, or they’re more likely to sweat that leads to oily hair, we can give them the context so they can plan.
California Water Futures Begin Trading Amid Fear of Scarcity
Water is joining gold, oil and other commodities traded on Wall Street […] Farmers, hedge funds and municipalities alike are now able to hedge against — or bet on — future water availability in California, the biggest U.S. agriculture market and world’s fifth-largest economy. […]
The futures are tied to the Nasdaq Veles California Water Index, which was started two years ago and measures the volume-weighted average price of water.
California is gonna have to ration water. You wanna know why? Because they send millions of gallons of water out to sea, out to the Pacific. Because they want to take care of certain little tiny fish, that aren’t doing very well without water.
When privately owned land vanishes under the water, who does it belong to?
The problem is a result of the state’s rapidly changing landscape. About 80 percent of Louisiana’s coast is privately owned. But, under an old law, as coastal erosion and sea level rise turn the land into open water the area becomes property of the state, including the mineral rights underneath.
Private landowners have become more adamant about restricting access to water on their property in order to assert their claim to the minerals underneath it. But boaters often have difficulty figuring out where private property ends and public waterways begin. Since 2003, Louisiana law does not require landowners to post signs demarcating their property. The resulting confusion led the Bass Anglers Sportsman Society, or BASS, to announce in 2017 that it would no longer host professional fishing tournaments in Louisiana tidal waters, where fishers risk being arrested.
Urgency Reader is a quick assembling of texts, risograph printed in Pawtucket, RI, and bound as a book at the last minute to launch at the Odds and Ends Art Book Fair at Yale University Art Gallery on December 6, 2019. […] Inspired by Omnibus News #1 (1969), Assembling (1970–87), and other assembling publications, Urgency Reader is an experiment in publishing as a gesture of call and response: the quick circulation of a charged collection of texts—in some cases raw, in-progress, or sketchy—to a small but deeply engaged audience. […] The order of the texts as they appear in the book was determined by chance by assigning a series of random integers from random.org to the alphabetical list of contributors.
In 1969 three Germans, Thomas Niggl, Christian D’Orville and Heimrad Prem, issued a call for submissions for a periodical in which interested individuals were invited to submit up to 2 pages of art works in an edition of 1500 copies each. Contributors were responsible for the cost of reproducing their own submissions, and all works would be accepted with no editing or censorship. Published the same year under the title Omnibus News, the periodical was comprised of 192 submissions (384 pages) sequenced alphabetically in an A4 format and in an edition of 1500.
Whatever goes down the sink, shower, washing machine and toilet is transferred to one of about 14,000 U.S. wastewater treatment plants. While those plants are good at neutralizing sewage microorganisms that can make people sick or pollute waterways, they can miss chemicals that are linked with our changing lifestyles.
The biggest change since most treatment plants were designed? The explosion of pharmaceutical use by Americans. […] About 60% of American adults take at least one prescription pill every day. Residue from those pills travels to treatment plants and waterways.
Active, polymorphic material (“Utility Fog”) can be designed as a conglomeration of 100-micron robotic cells (‘foglets’). Such robots could be built with the techniques of molecular nanotechnology […] The Fog acts as a continuous bridge between actual physical reality and virtual reality.
How much water goes into a cup of tea? Somewhere around 30 litres of water is required for tea itself, 10 litres for a small dash of milk and a further 6 litres for each teaspoon of sugar. This means that a simple cup of tea with milk and two sugars could actually require 52 litres of water.
For Pink Floyd’s 1975 triple platinum Wish You Were Here album, Capitol Records execs headed to the L.A. offices of Stunts Unlimited. Ronnie Rondell, 59, a veteran of TV shows such as Baretta and Charlie’s Angels, was cast as the man on fire. “I got $500 and only worked an hour.” Fellow stuntman Danny Rogers, 53, the glad-hander, was paid only $250 but caught a lot less heat during the carefully controlled shoot on a nearby movie lot, where a crew armed with fire extinguishers stood by. Rondell’s suit was painted with rubber cement and ignited three times before it ripped and his flame-retardant long Johns peeked through the holes. His eyebrows and eyelashes were singed in the process. “It’ll happen in a heartbeat,” says Rondell. “The fire wraps around your face real quick, like a barbecue thing. The wig was fried, it melted up into a ball.”
The researchers recruited 25 non-obese adult subjects. All had moderate sleep apnea, with somewhere between 15 and 30 episodes per hour at night. (All them also reported that they snored.)
Fourteen of these subjects were randomly assigned to learn the didgeridoo. […] They learned proper lip technique and circular breathing (inhaling through the nose while continuously blowing on the instrument). They also had to practice at home for at least 20 minutes a day, five days a week.
After four months […] people who’d been playing the didgeridoo had fewer sleep apnea events at night. And they reported feeling significantly less tired during the day.
Piper Jaffray analyst Stan Meyers said animated films generally cost about $100 million to make, as well as an additional $150 million to promote.
An executive producer who wants to drastically cut costs traditionally has two choices: water and hair. Those are the most expensive things to replicate accurately via animation. It’s no mistake that the characters in Minions, the most profitable movie ever made by Universal, are virtually bald and don’t seem to spend much time in the ocean.
Redbird Reef is an artificial reef located in the Atlantic Ocean, off the coast of Slaughter Beach, Delaware.
The reef comprises 714 ‘Redbird’ New York City Subway cars, 86 retired tanks and armored personnel carriers, eight tugboats and barges, and 3,000 tons of ballasted truck tires.
“Water fountains have been disappearing from public spaces throughout the country over the last few decades,” lamented Nancy Stoner, an administrator in the Environmental Protection Agency’s water office. […]
By 1930, Chapelle says, bottled water had become “low class,” used only in offices and factories that couldn’t afford plumbing.
Attitudes began to shift in the 1970s, when Europe’s Perrier set its sights on the American market. In 1977, the company spent $5 million on an advertising campaign in New York, selling itself as a chic, upscale product. Yuppies lapped it up. “It was a lifestyle-defining product,” Chapelle says. By 1982, U.S. bottled-water consumption had doubled to 3.4 gallons per person per year. […]
U.S. consumption of bottled water quadrupled between 1993 and 2012 (reaching 9.67 billion gallons annually). […]
Today, 77 percent of Americans are concerned about pollution in their drinking water, according to Gallup, even though tap water and bottled water are treated the same way, and studies show that tap is as safe as bottled.
The weather impacts not only upon our mood but also our voice. An international research team has analysed the influence of humidity on the evolution of languages.
Their study has revealed that languages with a wide range of tone pitches are more prevalent in regions with high humidity levels. In contrast, languages with simpler tone pitches are mainly found in drier regions. This is explained by the fact that the vocal folds require a humid environment to produce the right tone.
The tone pitch is a key element of communication in all languages, but more so in some than others. German or English, for example, still remain comprehensible even if all words are intonated evenly by a robot. In Mandarin Chinese, however, the pitch tone can completely change the meaning of a word.
