Paradise, California and the impossible choice between climate fight and flight

The town’s residents are rebuilding in the wake of the Camp Fire. But should they?                      By James Temple

On the morning of November 8, 2018, clouds of black smoke rose above the community of Paradise, California, raining burning embers on the ridge that some residents initially mistook as hail.

When Gloria Rodgers and Jim Umenhofer spotted the darkening sky from their home on the western edge of town, they knew it was time to pack their cars with all the belongings they could gather. But when they heard the propane tanks around town begin to explode, they knew it was time to leave the rest and go.

By then, thousands of people were piling onto the few streets to safety. It took the couple nearly four hours to reach the edge of town, where the Paradise welcome sign had collapsed in a burning heap in the median strip.

In the end, the Camp Fire destroyed 90% of the town’s homes and killed 85 people.

But eight months after fleeing the deadliest inferno in California’s history, much of that time spent living in a recreational vehicle on a friend’s driveway one town away, Rodgers and Umenhofer are ready to return to Paradise.

They realize that their land, shaded by a canopy of ponderosa pines even after the blaze, has become more dangerous during the four decades they’ve lived there. Climate change has made California’s summers hotter and drier, converting much of the forests and grasslands of the Sierra Nevada foothills into tinder for extended stretches of the year.

“This is the first fire of its kind,” Rodgers says. “I don’t think it’ll be the last fire of its kind, because of what’s going on with the climate.”

But they believe they can rebuild in a safer way. They’ve hired a contractor to draw up plans for a new house that will exceed state and town standards, employing fire-resistant cement building materials in place of their wood shingles and installing vents that slam shut under high heat.

“So yeah, we’re going to rebuild,” Umenhofer says. “But we’re going to harden it up, you bet.”
Rebuild or flee?

Mayor Jody Jones says town officials never entertained the idea that they wouldn’t rebuild in the wake of the Camp Fire (see “The day I tasted climate change”).  Instead they’re forging ahead with a plan to resurrect Paradise in a way that they hope will prevent a repeat disaster.

But as climate disasters exact ever higher human, economic, and environmental tolls, society will have to become more pragmatic about whether to rebuild or retreat. Some places will simply become too dangerous to continue living in, and too expensive and hazardous to keep rescuing and rebuilding—if they haven’t already.

The Camp Fire was the world’s most expensive natural disaster for insurers last year, with an estimated $16.5 billion in total losses, according to German reinsurance company Munich Re. The California Department of Forestry and Fire Protection (Cal Fire) spent nearly $94 million fighting the blaze. The state and the Federal Emergency Management Agency will pick up the majority of clean-up costs, which could top $3 billion.

And fire risks will continue to rise. Climate change has already doubled the area burned by wildfire across the western US in recent decades. Under the higher estimates of carbon emissions, the land scorched in Northern California’s forests could double again by 2085, while the risk of “very large fires” will more than triple across vast parts of the American West.

Sea-level rise is likely to be even more disruptive, displacing more than 13 million people in the US and nearly 200 million worldwide by the end of the century, under some of the grimmer climate-change scenarios.

A rising number of researchers are starting to explore the thorny questions these looming dangers present. When should communities stay or go? Who gets to decide? And how do you ask—or force—an entire community to pick up and leave?

“There’s this growing recognition of the inevitability around retreat—and a recognition that actually implementing it is invariably, unbelievably hard,” says Katharine Mach, a senior research scientist at Stanford.
Who pays for Paradise?

So how do we determine whether a city, town, or neighborhood should stay or go after a disaster, or in anticipation of one?

Researchers studying what’s known as “managed retreat” say the decision will turn on four factors. The first three: whether we have the technological means to address the rising risks, whether we can afford them, and whether the cost of the job would exceed the value of the buildings, roads, and other assets that would otherwise be lost.

But the fourth factor will often be the hardest to resolve: social conflicts and public outcries over any decisions to adapt or retreat. People will fight against higher seawalls that lower their property values or block their views. But they’ll also resist abandoning their homes.

Tensions have already emerged in Paradise.

Early last month, the town council moved its monthly meeting from the town hall to the Paradise Alliance Church because of the expected size of the crowd. On the docket that Tuesday evening were 20 fire safety standards that would exceed state rules.

They’re part of a recovery plan that includes bolstering emergency notification systems, widening evacuation routes, and burying the electricity lines that sparked the fire on that November morning. (See “How a town destroyed by fire is trying to make itself fireproof.”)

After a fire that destroyed 19,000 structures, you might expect that everyone would want the strictest fire standards imaginable. But you’d be wrong.

In the lobby before the meeting began, Woody Culleton, stage manager at the Paradise Performing Arts Center and a former town mayor himself, had buttonholed councilman Steve Crowder.

“Now’s the wrong time to pass new laws, to add new mandates,” he said, stressing that it will raise costs for people already struggling to move back.

As another council member, Michael Zuccolillo, walked in, Culleton shouted out, “Vote no on everything.”

State regulations like the wildland-urban interface rules that went into effect in 2008, well after most of the town was built, are adequate to ensure greater fire safety in the future, Culleton told me. Among other things, those standards require fire-resistant roofing materials, and vents that prevent embers from entering the home. Other state building regulations stipulate that plants, trees, and wood piles must be far enough away from structures, and properly spaced and maintained.

But Urban Design Associates, a disaster recovery firm that’s worked with the town since February, proposed further measures, like mandating a five-foot fire break around any structure (which would rule out wood fences running up to a home); eliminating most gutters, except for those above entrances; and requiring sprinklers for all types of homes.

Culleton, who had already begun rebuilding, said those should only be recommended best practices, not rules, unless the town wants to pay for them.

Why, given the disaster he faced, didn’t he just want to move on?

“I’m 74. My mortgage is $550 a month. Where else can I go?” he said.

During the public comment period before the votes, other Paradise residents expressed concerns that the new fire safety standards would cost too much, or sacrifice some of the town’s charm by forcing people to chop down trees.

“You’re taking away some of the risk, but you’re also taking away a lot of the beauty of this town,” Vincent Childs said. “We like the look of the town. It’s forested, it’s shaded, it’s green, it’s beautiful. We are willing to accept some risks.”

In the end, the town council rejected 11, weakened five, and approved four of the proposed standards.
Burnt out

But after several devastating seasons in a row, signs are emerging that California is suffering from fire fatigue. While few are vocally calling for abandoning towns en masse, Ken Pimlott, the recently retired director of Cal Fire, told the Associated Press after last year’s fires that officials need to consider banning new development in high-risk areas. (See “California needs to reinvent its fire policies, or the death and destruction will go on.”)

Home insurers are already becoming stricter about offering policies in fire-prone locations. Over time, that could bring down property values and prevent people from moving to certain areas.

Meanwhile, a recent poll by the University of California, Berkeley, found that three out of four Californians are in favor of limits on new housing in such areas. But the release added that up to one in four Californians, or about 10 million people, already live in places that could qualify as high fire-risk areas, raising questions about where new development and growth could occur.

Some Paradise residents have had enough. Signs litter the yards, fences and billboards along Skyway, the main thoroughfare through town. While many advertise debris clean-up and demolition services, “For Sale” signs seem to outnumber them.

John Gilmore moved down the road to Magalia, California, with his wife, daughters, and dog, and doesn’t plan to return. Standing on the lot where their home used to be, he said the town should be doing even more to reduce fire dangers.

“I don’t know what they think’s going to happen when the next fire comes through with all this dead wood; it’s going to be three times as hot,” he says. “It’s going to be more expensive, but building houses five times in a row if it keeps burning down is expensive too.”
How to beat a retreat

Not every town stays as stubbornly put as Paradise. In fact, governments move communities more often than you might expect. A 2017 Nature Climate Change study by researchers at Stanford University identified 27 cases where the process of managed retreat had at least begun in the last few decades; this could ultimately relocate around 1.3 million people.

The researchers found that relocation is most likely and happens fastest when residents themselves believe they face serious dangers. It also helps when moving them will benefit other people too. For example, the Netherlands relocated a few small communities along the banks of the Rhine to create room for spillways when the river swells. These dramatically lowered the flooding risks for much larger cities upstream.

On the flip side, isolated areas may not get help as readily from the government. For instance, Alaskan villages like Newtok, Shishmaref, and Kivalina have been asking the US government for relocation assistance for years. The settlements have been struggling with coastal erosion, thawing permafrost, fierce storms, and flooding as temperatures and sea levels rise around the Arctic Circle.

But the cost of setting up new, nearby communities with all the necessary infrastructure is high—hundreds of thousands of dollars per resident—while the perceived societal benefit is low. Few Americans have ever heard of the small, remote villages. In 2016, Congress rejected the Obama administration’s proposal to set aside hundreds of millions of dollars for them.
Love of the land

Sitting at a red picnic table set up on what was the front yard of their guest house in Paradise, Rodgers admits she sometimes thinks about buying a quiet farm, with goats and a garden, a good distance from the woods.

It’s tempting to get far away from the next fire in the foothills. And who needs the hassle of rebuilding a home on a lot that won’t get water or electricity for months, and living in a town that will take years to rebuild and repopulate?

But for all the good reasons to move away, she and Umenhofer didn’t consider it for long. When they first returned to their property in January and spotted a family of deer with fawns on the lawn, the same ones they’d noticed on the day they fled, “that sealed the deal,” Rodgers says.

They’ve been making the drive to the property a few times a week to clear burned brush, or simply to spend time on the land. Rodgers has begun gardening a little, planting milkweed, wildflowers, coreopsis, and sweet peas.

As soon as state agencies sign off on soil tests, the town issues permits, and the electricity and water come back, they plan to begin construction. Umenhofer expects to break ground by October.

The land overlooks Little Butte Creek Canyon, a plunging clay and yellow chasm covered by grasses, chaparral, and trees. They’ve watched bucks square off and lock antlers in their backyard. Occasionally a black bear will wander through.

“We were really fortunate to have lived here for 43 years in the forest,” Rodgers says. “It’s not going to be the same. We’ll have a few big pine trees, but we’re not going to be living in the woods anymore.”

“But we feel really attached to the land,” she says, “so I think that’s it for us.”

A biotech startup is making cow-free ice cream. Would you eat it?
Perfect Day says it’s figured out how to make ice cream that’s creamy without any animal protein.
woman holding ice cream cone

A company called Perfect Day has announced that after five years and $60 million in venture backing, it’s created ice cream made of whey protein harvested from genetically modified yeast....

The scoop: The market for non-dairy ice cream has exploded over the past few years; in 2017, Nielsen expected that demand for dairy-free ice cream was expected to climb 50%, thanks to the growth of veganism and the increasing availability (and popularity) of non-dairy ingredients like oat, coconut, and even chickpea milk.

What makes Perfect Day allegedly different? Anyone who’s tasted non-dairy ice cream knows it sometimes seems sandy, chalky, or just … not like the real thing. That’s because one of the things that make ice cream so, well, creamy is the whey protein that is prevalent in cow’s milk. Cashew and coconut milks come close because they, like their bovine-derived counterparts, contain plenty of fat, which helps give frozen treats their silky texture. But they’re not the same. Perfect Day, however, engineered yeast to produce whey proteins, which means it possibly created the ultimate compromise between vegans, the lactose intolerant, and everybody else.

Is it genetically modified? Yes and no. On its website, Perfect Day says the yeast is genetically modified to turn sugars into whey and casein. But the company says only the “pure” whey makes it into the ice cream.

Does it hold up? Still unclear. One writer from The New Food Economy, a vegan, found the product creamy enough to stand by its dairy-free cousins. But the verdict is still out on how it compares in taste with ice cream made from old-fashioned cow’s milk.

Watch this robot do the Bottle Cap Challenge—and show a new way to control machines

It isn’t quite a roundhouse kick, but check out the robot above in a simpler version of the “Bottle Cap Challenge.” (If you haven’t come across this yet, it consists of people trying to kick the top...

Why, tho? Social-media kudos aside, what the video actually demonstrates is an effective new way to control and interact with a robot.

How’s it work? The underlying system, called RoboRaise, monitors a person’s muscles using EMG sensors, with help from a machine-learning algorithm that maps signals to physical movement. The robot then tries to mimic a person’s movements, although a user can also exert some control through careful flexing. It can be applied to any robotic hardware.

Robots like us: Despite so much talk of “robots replacing people,” the future is likely to involve a great deal of cooperation and collaboration. There will be many situations where a human’s intelligence and adaptability are required to help machines accomplish a task.

The Bottle Cap Challenge might be a pointless exercise, for both humans and robots, but in this case it shows the kind of deft control that could help us interact with technology more effectively in the future.

Humans might be listening to your Google Assistant recordings

Google’s privacy policy page makes no mention of the fact human contractors listen to some of the recordings....

The news: In a report this week, Belgian public broadcaster VRT NWS revealed that it had been leaked thousands of audio clips recorded by Google Assistant, a virtual AI assistant embedded in Google devices, including its Home smart speaker. They were shared by a contractor paid to transcribe the recordings as part of work to improve the software’s accuracy.

The clips include fragments of deeply personal conversations, including people’s addresses, information on someone’s love life, and what sounded like a woman in distress. Many of the recordings were captured accidentally, because the speaker had incorrectly identified the “wake word.” As we learned in April, Amazon does the same with Alexa clips.

Google’s response: In a blog post, Google said that just 0.2% of all recordings are transcribed, and that users have the option to stop Google from storing their audio data.

Legally questionable: Because Google doesn’t inform users that humans review recordings in this way, and thus doesn’t seek their explicit consent for the practice, it’s quite possible that it could be breaking EU data protection regulations. We have asked Google for a response and will update if we hear back.

France has passed its new Big Tech tax—and the US is not happy

The French parliament has just approved a 3% digital sales tax aimed at closing the loopholes big tech companies use to bring down their tax bills.  ...

The plan: The tax on sales generated in France will apply to companies with global revenues over €750 million ($849 million) or French revenues over €25 million. It is expected to raise about €500 million a year.

A backlash: Inevitably, most of the companies affected are based in the US. It’s for that reason that the US government has ordered an inquiry into the new tax, with the potential to implement tariffs on French goods in retaliation.

First of many: The low tax yield from wealthy global tech firms is controversial far beyond France. The UK, Spain, Italy, and Austria are considering similar sales taxes, raising the question of how the US will respond if they take effect. Perhaps it might even prompt countries to finally agree on some common tax rules (imagine that).

A Japanese spacecraft just grabbed more rocks from the asteroid Ryugu

Hayabusa2 has collected a second sample from the asteroid’s surface. It could give us a unique insight into how the early solar system was formed....

The procedure: After a few hours of maneuvering, the spacecraft touched down on Ryugu’s surface at 9:15 p.m. US Eastern time yesterday. It then fired a bullet into the asteroid and collected some of the debris stirred up by the shot. The Japanese space agency JAXA tweeted that the mission had been a success and that the space probe had now left the surface again. It’s the second sampling mission after a similar one in April, and it required particularly careful preparations, because any problems could cause the materials gathered during the first operation to be lost. In April, Hayabusa2 had also fired a copper bomb into the asteroid’s surface to expose the rocks beneath, in anticipation of today’s mission.

Next steps: Hayabusa2 is scheduled to return to Earth at the end of this year, but before it does it has a final task: deploying a smaller rover called MINERVA-II2 later this summer. Its primary goal will be to explore in an environment where there is very little gravity.

Long game: Ancient asteroids like Ryugu provide clues about the formation of the early solar system (including our own planet), which is what makes the samples Hayabusa2 has collected so important. Labs on Earth will be able to start analyzing its cargo once it returns home toward the end of 2020.

The spyware used by Arab dictators has now shown up in Myanmar

A powerful German spyware company had its hacking tools spotted in Myanmar....

The news: One of the oldest private hacking companies around found itself in the spotlight again this week. Gamma Group, a German company that sells spyware to the highest bidder, was discovered within the last year to be spying on dozens of mobile devices in different parts of the world by the Russian cybersecurity company Kaspersky. Last month, Kaspersky found Gamma Group’s FinSpy malware in Myanmar. The hacking tool known as FinSpy, if successful, steals everything from text messages to emails, photos, and GPS data. It also targets secure and encrypted messengers like Signal, WhatsApp, and Telegram. Those apps, often used for their exceptional security against hackers at a distance, offer little protection against malware that’s successfully executed on a target’s phone.

The background: Today, there is a global multibillion-dollar hacking industry. Gamma Group came to prominence when it was discovered selling spyware to Middle East dictatorships during the Arab Spring.

The target: It’s not clear yet who was the aggressor and who was the target, but these tools are increasingly used by authoritarian governments to suppress dissidents and political opponents. Myanmar has endured a series of uniquely 21st-century catastrophes, most notably an ethnic genocide fueled by social media. Silicon Valley, Facebook in particular, was slow and ineffective in its response even as people died as a result of misinformation and hate speech on the platform. Last month, the government shut down the internet during a time of heavy fighting and humanitarian crises.

The future: Gamma Group is one company among many that governments around the world are paying for high-tech hacking capabilities. Although countries like the US and China can afford to develop world-leading exploits and vulnerabilities, dozens more countries—from democracies to dictatorships—are turning to the booming private sector for their hacking abilities. The results can be seen in Saudi Arabia, which reportedly has hacked journalists; the United Arab Emirates, which hacked dissidents; and Mexico, which hacked lawyers and even politicians, among others. Gamma Group’s resurfacing in Myanmar is the latest sign of the industry’s global reach.

China has slashed clean energy funding by 39%, leading a global decline

Worldwide funding of clean-energy projects fell to its lowest level in six years, in a staggering blow to the battle against climate change....

The findings: BloombergNEF found that global investments in solar, wind, and other clean energy sources added up to $117.6 billion during the first half of 2019, a 14% decline from the same period last year and the lowest six-month figure since 2013.

China saw a 39% drop in investments, as the nation eases up on its aggressive solar subsidies to get costs under control. But spending also declined 6% in the US and 4% in Europe, part because of policies that are being phased out and weak demand for additional energy generation in mature markets.

The big picture: The new report suggests last year’s slowdown in renewable-energy construction has extended into 2019, taking the world in exactly the wrong direction at a critical time (see “Global renewables growth has stalled—and that’s terrible news”). Every major report finds that the world needs to radically accelerate the shift to clean energy to have any hope of not blowing past dangerous warming thresholds (see “At this rate, it’s going to take 400 years to transform the energy system”).

More bad news: BNEF found that private investments into clean energy companies also declined, ticking down 2% to $4.7 billion, limiting the pipeline of the innovative new companies needed to solve remaining challenges in the climate puzzle.

Reversing the trend: Preventing the spending dip from solidifying into a sustained trend will almost certainly require more aggressive government policies, both pushing clean energy development and providing incentives to increase private investment.

Amazon Alexa will now be giving out health advice to UK citizens

The UK’s National Health Service hopes that its partnership with Amazon could help to reduce demand on its services....

The news: From this week, when UK users ask their Amazon smart speaker health-related questions, it will automatically search the official NHS website, which is full of medically backed health tips and advice. For example, you will be able to ask your Echo device, “What are the symptoms of flu?” Until now, it would answer these sorts of questions based on a variety of popular responses.

The aim: The government believes it will ease the burden on over-stretched doctors and hospitals, but also help elderly, disabled, or blind patients who may struggle to access this information otherwise, according to the UK health secretary Matt Hancock. The UK already has a deal with Babylon, an AI app that provides basic answers to queries about symptoms.

The worries: There are concerns that the voice service might discourage genuinely ill people from seeking proper medical help. The service will only provide answers to questions rather than the sort of back-and-forth conversation you would have with a doctor.

The professional body for family doctors, the Royal College of GPs, called for independent research to be carried out to ensure that the advice given is safe. It being Amazon, there are also concerns over data privacy, especially in an area as sensitive as health. However, the company insists that all data is encrypted and confidential, and can be deleted by customers.
