A beautifully filmed journey to the bottom of the globe reveals new risks to the planet
There’s an old saying: “Everybody talks about the weather, but nobody does anything about it.” Well, here’s a film about a few people who are doing something about extreme weather. Every spring (in the Southern Hemisphere) oceanographers and ecologists of the Long Term Ecological Research (LTER) project make the arduous journey to Palmer Station in the West Antarctic Peninsula. The area has been described as “the fastest winter-warming place on Earth,” and because of that unfortunate distinction it is among the best places on the planet to study the impacts of global climate change.

For the first time since LTER was established at the remote Palmer outpost by the United States National Science Foundation in 1990, a crew of filmmakers were allowed to accompany LTER team members to Antarctica. The resulting documentary film – Antarctic Edge: 70° South – is impressive. Director Dena Seidel and her crew have made one of the most informative films shot on location in the polar regions since Robert Flaherty’s groundbreaking Eskimo epic Nanook of the North was made at the Canadian Arctic in 1922. But instead of focusing on human inhabitants, Antarctic Edge: 70° is primarily concerned with the West Antarctic Peninsula’s penguins, whales, elephant seals, and seabirds as they confront global warming.
With a “you-are-there” vibe Seidel’s digital cameras transport viewers to the world’s final (if no longer fully frozen) frontier, one that’s sometimes literally off the charts. Various peninsula sites are still designated on maps as “PA” and “PD”: Position Approximate or Position Doubtful. The documentary, funded in part by National Science Foundation, opens with this worrisome caption, “May 2014: Scientists declared West Antarctic ice sheet melt unstoppable.” Throughout the film members of the interdisciplinary team of scientists explain the implications of that fact, which usually come across as dire pronouncements.
Biological oceanographer Oscar Schofield, who made his first Antarctic excursion in 1987, described the continent then as being “the land of the gods… like no other place on Earth.” But now the place is changing. The season for growing winter sea ice at the West Antarctic Peninsula is now, astonishingly, three months shorter per year. Antarctic Edge points out this reduction in ice has the potential to not …more
As Brazil's São Paulo taps out its water reserves, questions linger about how much the state's water utility distributes to sugarcane for ethanol production
By now, most are aware of California's unprecedented mandatory water restrictions, which Governor Brown ordered earlier this month. Many also know that these limits apply exclusively to urban water agencies, even though cities use only about 20 percent of California's total surface water reservoirs. California farms, on the other hand, use 80 percent of the state's surface water. While Governor Jerry Brown has defended this allocation for economic reasons, critics note that agriculture only accounts for 2 percent of the state's GDP. Regardless, the power of the agriculture lobby may ensure that pressures to cut back on water use will be shouldered by ordinary citizens living in Los Angeles, San Francisco, and other growing cities across the state.

The water pains in the world's seventh largest economy are also being felt within the eighth: Brazil. The nation's most populous city, São Paulo, officially tapped out its supply of water on March 15, leaving millions with water access at only irregular hours, and millions of favela dwellers with even less access to water. The Guardian reported of neighbors fighting over measly remaining water reserves, and of armed groups looting emergency water trucks; NPR says people are drilling guerrilla wells across the city, potentially contaminating underground aquifers.
Last year, two of the main reserve systems that supply the city with water, the Cantareira and the Alto Tietê, were hit especially hard by drought, which the governor of São Paulo state has blamed for current water shortages. However, a UN report shows that reserve volume had already been declining for the past five years, meaning that the drought simply compounded management problems. The report cites mismanagement and poor preparation by the state government and its semi-public water utility, SabeSP, which distributes and purifies water in the region.
This has raised questions over how SabeSP distributes water between urban areas like São Paulo city and surrounding agricultural land. Like California, much of the available surface water in São Paulo state is directed toward agriculture (45 percent) or industry (14 percent). A further 36 percent is completely lost to …more
Can more mechanization reduce the use of chemical herbicides?
Weeds, farmers’ biggest headache since time immemorial, just won’t stop popping up.
Modern agricultural technology thought it had weeds beaten with its synthetic pesticides and gene manipulation. But nature has come roaring back with evolved weeds robust enough to resist the chemicals farmers typically throw at them. And so they throw more. But herbicide overuse threatens the health of insect and animal life, and maybe ours, too. Last month an agency of the World Health Organization declared glyphosate – the active ingredient in Monsanto’s Roundup – a possible human carcinogen.
But technology may yet come to the rescue. Teams of engineers around the world are hard at work inventing cutting-edge, weed-busting robots to step in and take over from broadcast herbicides. These robots just might make good on biotechnology’s broken promise: reducing the amount of chemicals used to grow our food.
Technology has made it possible for just 2 percent of the US population to feed the rest of the nation. Biotechnology’s herbicide-tolerant crops made weed suppression easier with blanket spraying. Today, the vast majority of soybean, corn and cotton fields are planted with glyphosate-tolerant varieties.
According to a study by Charles Benbrook, total herbicide use in the United States increased by 527 million pounds between 1996 and 2011. That opened the door to glyphosate-resistant weeds, which now infest more than 62 million acres of US cropland, threatening farmers’ yields. The farm chemical industry’s solution? They’re promoting new seeds, this time tolerant of the additional and more toxic herbicides 2,4-D and dicamba. The chemical treadmill just keeps going.
Now, it’s a long way from “The Jetsons” to today’s farm robots. Most weeding bots still can’t navigate themselves around a farm field. They depend on a human driver, who brings a common sense approach, something engineers can’t yet program into computers.
But what robots do bring is enough accuracy and precision to potentially reverse escalating herbicide use trends (though they would not necessarily eliminate the use of herbicides). Using sophisticated computer vision technology, robots can distinguish weeds and either uproot or shoot them with tiny spot sprays of a deadly liquid. Even if that liquid is a conventional herbicide, …more
Failure to intervene will have lasting impact on marine ecosystem and coastal economy
Pacific sardines are in the midst of a crash, the likes of which hasn’t been seen since the 1950s. When asked where the sardines had gone in the years following World War II, scientist Ed Ricketts famously answered, "They're in cans.” As a result, the once bustling canneries of Monterey were abandoned. Today, the Pacific sardine is once again imperiled, and fishery managers must act swiftly to stop current overfishing of this species.

The collapse of Monterey's sardine fishery in the 1950s was due to the natural boom and bust cycle of this forage fish, exacerbated by a largely unregulated fishery removing sardines at an unsustainable rate during a natural bust. While the sardines eventually came back, they never rebounded to their historic highs. Scientists estimate the sardine population was over 3.5 million tons in the 1930s. Now the population is hovering at less than 3 percent of that historic peak and little of the catch is actually feeding people. Instead, most of the sardine catch is used as fishmeal and shipped abroad to feed larger farmed fish, like penned bluefin tuna. The next generation is now watching as history repeats itself, the ocean again being emptied of this critically important small fish.
Three years ago, federal fishery managers failed to heed the warning signs of a second sardine fishery collapse. In 2012, top sardine scientists clearly cautioned of a severe collapse unless precautionary measures were taken to avoid it. While the Pacific Fishery Management Council did reduce the catch levels of sardine as the stock declined, they did not act fast enough.
The Council’s own scientists reported last week that, while there has been a natural decline of the sardine population in recent years likely due to ocean conditions, today’s sardine population would have been four times higher than current levels in the absence of fishing. It is clear that fishing pressure has a direct impact on abundance of this forage fish. Without precautionary measures to account for natural variability in this inherently boom and bust stock, disaster is inevitable.
With the sardine population in collapse, fishing vessels are turning to anchovy to fill the void. But Northern anchovies, another critical …more
Lawsuit says the marine entertainment company misleads the public about the health and wellbeing of captive orcas
SeaWorld has been treading water for the past few years as it faces ongoing criticism about its captive orca program. The marine entertainment behemoth may soon find itself sinking: Today, a new lawsuit was filed against SeaWorld claiming that the company makes false and misleading statements about the health and welfare of its captive whales.

The lawsuit, filed in San Francisco Superior Court on behalf of two plaintiffs, includes a long list of allegations regarding how SeaWorld represents captive orcas in its advertising. Many of the claims concern the physical heath of captive whales. Take orca lifespan, for example: SeaWorld claims that captive orcas live just as long as orcas in the wild. Plaintiffs counter that SeaWorld orcas die at an early age, years earlier than their wild counterparts. Similarly, SeaWorld has said that all male orcas experience dorsal fin collapse. Plaintiffs say that isn’t true, that dorsal fins collapse results from unhealthy captivity in small tanks, and only occurs in a very small percentage of wild orcas.
The false claims alleged in the lawsuit also extend to psychological health. SeaWorld depicts captive orcas as happy in its advertising materials. According to plaintiffs, this is far from the truth, and captive SeaWorld whales are often treated for stress-related ulcers and depression. Also, captive orcas frequently chew on the metal bars separating their pools, an indication of boredom. This chewing can cause broken teeth, leading to cavities and infection. According to plaintiffs, the conditions of captivity — including small tanks and the practice of placing orcas from different pods together — also cause increased aggression and bullying between whales.
Another allegation is that SeaWorld lies about keeping marine families together. According to the plaintiffs, SeaWorld, although it states otherwise, separates young orcas from their mothers; in the wild, calves typically stay with their mothers for most of their lives.
Plaintiffs say they would not have purchased tickets to SeaWorld San Diego if they had known that captivity was so detrimental to orcas, and argue that SeaWorld’s statements violate consumer protection laws.
“SeaWorld is luring people to buy tickets based on a pack of false and misleading statements, …more
Biotech firm's acquisition of Climate Corporation will help farmers plan for severe weather
By Marc Gunther
David Friedberg, CEO of The Climate Corporation, expected pushback when he decided to sell his San Francisco-based big data company to Monsanto. He was surprised, though, when some of the loudest criticism came from his own father.

Lionel Friedberg – a Los Angeles filmmaker whose 1989 documentary, Crisis in the Atmosphere, was one of the first films to highlight the problem of global warming – reacted to the news by berating his son. “Monsanto? The most evil company in the world?” Friedberg recalled his father saying. “I thought you were trying to make the world a better place!”
As Friedberg the younger wrote in an email to Climate Corp employees after the 2013 sale, being chastised by his own dad “was really hard”. But he’s nothing if not a believer in facts, and so he marshaled enough evidence to persuade his father that the $930m sale to Monsanto was not just good for his business, but good for the planet. His email is worth reading, particularly if, like Friedberg’s dad, you’re a critic of Monsanto.
Now Friedberg and his colleagues need to persuade the world’s farmers that Climate Corp will help them save money, improve yields, adapt to climate change and improve the environment. And if the company manages to turn around a few more Monsanto critics, that would be a bonus.
Sustainability through precision
Founded in 2006, Climate Corp is a leading player in the fast-growing business of precision agriculture. Using a data-driven approach, it seeks the most efficient use of fertilizer, seed, pesticides, land and water. It’s the next big idea in farming, Friedberg claimed when we met at his office in San Francisco. He compared the approach to the industrialization of agriculture, the green revolution and modern plant breeding.
“We have these quantum leaps,” Friedberg said. “This one is going to be driven by the digitization of agriculture. We’re able to more accurately monitor, through digital technology, what’s going on in the field. Then we’re able to accurately execute and optimize decisions, applications and investments.”
“Technology is how we solve all the great problems that we have to tackle, …more
Artist Andres Amador seeks to highlight the power of the impermanent
Andres Amador says that when he’s in the midst of creating one of his epic beach art installations, passers-by often become anxious when they notice the tide coming in. Many viewers just can’t grasp that someone would take the time to create such a beautiful piece of art, knowing that it’s fated to disappear. “There’s a sense of wonder, that someone would make something so large, and that it would wash away within a few hours,” says Amador, 43, a San Francisco Bay Area-based artist. “People are like, ‘Oh, it’s going to wash away. Aren’t you upset?”
No, he isn’t – and that’s exactly the point.
Amador used to create huge, metal sculptures that he displayed at Burning Man. Then, about 10 years ago, he reached what he called a “creative impasse,” and began to experiment with impermanent nature art. For Amador, the short lifespan of beach art is precisely what gives the work meaning. “We spend so much of our lives in fear of the end,” he says. “If we can make peace with that fact, it came make the rest of our lives so much more meaningful. That’s what I’m trying to infuse into the art – the immediacy of life. You can’t come back to see it, because it won’t be there. You have to examine it now. I think that’s one of the gifts of ephemeral art.”
Amador usually only has a few hours to create his designs, the narrow window between when the sand dries enough to be able to shape and when the tide begins returning. Then – using only a rake, a three-pronged garden cultivator and (sometimes) string and stake to craft straight lines – he forms his designs. His patterns are often wave-like, an echo of the sea itself, or else looping, abstract forms that Amador calls “sacred geometry” (a term he says he always puts in quotes, because what that is might mean different things to different people). He usually works in a palette of nature motifs – interlocking lines like a web, or a lotus flower, or the long undulation of a snake’s body.
Although he’s had years to practice artistic detachment, Amador admits that sometimes it’s difficult to watch one of his creations blur into salt water. “It can …more
