St. Louis just became the biggest Midwestern city to commit to clean energy.

You’d think that, in an era of increasingly extreme weather and disasters that render whole regions of the country nearly uninhabitable for months, maintaining a weather service in tip-top shape would be a priority.

Turns out, under President Donald Trump, that hasn’t been the case. Shifting priorities and uncertainty over funding at the National Weather Service have led to as many as 700 current staff vacancies, according to a report in the Washington Post. That’s about 15 percent of its mandated positions.

“Given our staffing, our ability to fill our mission of protecting life and property would be nearly impossible if we had a big storm,” Brooke Taber, a weather service forecaster in Vermont, told her local paper.

Some offices, like the one in Washington, D.C., are missing a third of their workforce as hurricane season winds down ahead of winter, traditionally one of the busiest times of the year for storms. Although a weather service spokesperson denied the problem was hurting the quality of its forecasts, the service’s employees union said in a statement that the organization is “for the first time in its history teetering on the brink of failure.”

The report follows a Grist cover story this week that looked at how Trump’s proposed cuts to the National Weather Service are already making the country less safe.

Overworked and understaffed, the National Weather Service is “on the brink.”

Sure, the Arizona facility has been a significant source of funding for schools, infrastructure, and other public services. But the Sierra Club estimates that it has contributed to 16 premature deaths, 25 heart attacks, 300 asthma attacks, and 15 asthma emergency room visits each year. That adds up to total annual health costs of more than $127 million.

Beyond that, after natural gas prices fell, the coal-fired plant became unprofitable. So the owners of the Navajo Generating Station decided to close the plant by year’s end. Still, the Interior Department, which owns a 24-percent stake in the facility, has worked to extend a lease agreement through 2019 as it searches for another entity to operate it.

The closure won’t just shutter the plant, but also likely will close a nearby mine. Peabody, the largest coal-mining company in the U.S., began operating on Navajo land in the 1960s. Its Kayenta Mine’s biggest customer is the Navajo Generating Station.

But the mine’s demise mine might not be a bad thing, as it has depleted billions of gallons of water in the Navajo Aquifer and has led to water shortages for residents of the Navajo Indian Reservation.

Tesla’s solar vision gets its first big test in Puerto Rico

It was a transaction concocted on Twitter — and in a few short weeks, declared official: Tesla is helping to bring power back to Puerto Rico.

Early this month, Elon Musk touted his company’s work building solar-plus-battery systems for small islands like Kauai in Hawaii and Ta’u in American Samoa. He suggested a similar setup could work for Puerto Rico. The U.S. territory’s governor, Ricardo Rosselló, tweeted that he was game. Musk replied quickly: “Hopefully, Tesla can be helpful.”

After earlier reports of the company’s batteries arriving at San Juan’s port, Tesla announced today that it has started constructing its first microgrid installation, laying out a solar field and setting up its refrigerator-sized Powerpack batteries to supply electricity to a children’s hospital in the Puerto Rican capital.

More than a month after Hurricane Maria destroyed swaths of the island’s electrical grid, 85 percent of Puerto Rico is still without power. Total grid repair costs are estimated at $5 billion — an especially steep price for a public utility already $9 billion in debt. The lack of power is especially dire for hospitals, where unreliable electricity may spoil medicines that require refrigeration and complicate crucial medical procedures. The results could be deadlier than the storm itself, but solar power could help head off further disaster.

The idea that solar could serve as a viable source of emergency relief is new. Sure, renewable technologies have proliferated and become more affordable, but there’s a tried-and-true response to natural disasters: Fall back on diesel generators and fuel until utilities have a chance to restore grid power.

This has largely been the pattern in post-Maria Puerto Rico. One hardware store told the New York Times it was selling up to 300 generators a day. FEMA claims it has installed more generators in Puerto Rico than in hurricane-ravaged parts of Texas and Florida combined. But generators are expensive, inefficient, and prone to failure. And burning diesel in homes comes with health risks like carbon monoxide poisoning.

By contrast, a microgrid setup — that is, a combination of solar panels, battery storage, and electrical inverters that doesn’t require input from the main power grid — can potentially take immediate effect, providing reliable electricity with no pollution. And, once installed, these self-contained systems could help eliminate the rolling blackouts that were a problem for Puerto Rico’s major utility even before Maria.

Tesla is only the most prominent company to bypass the conventional avenues of rebuilding to install renewable power and batteries. Other companies and nonprofits have been marshalling resources to fill the void left by federal relief efforts. German renewable energy outfit Sonnen has pledged to build microgrids in priority areas, working with local partner Pura Energia to install donated batteries to power first aid and community centers. Another group, Resilient Power Puerto Rico, is distributing solar generators to remote communities, where they can serve as hubs for immediate necessities like charging phones and filtering water.

Marco Krapels, founder of the nonprofit Empowered by Light, traveled with a solar installation team to Puerto Rico in early October to deploy solar-plus-battery microgrid systems on fire stations. The nonprofit partnered with local firefighters to quickly cut through red tape paralyzing much of the disaster response.

“It takes only 48 hours to deploy once it arrives in the San Juan airport,” Krapels says of the standalone systems. “The firefighters, who have 18 flat-bed trucks, pulled up to our cargo plane; three hours later we were installing the system; and 48 hours later we’re done.”

The microgrid systems provide electricity and communications to the fire stations, as well as water purification technology that can provide up to 250 gallons of drinkable water a day — crucial on an island where 1 in 3 residents currently lack access to clean water.

There are 95 fire stations in Puerto Rico, Krapels says, and he estimates it will take just under $5 million for Empowered by Light to outfit them all. So far, the nonprofit has transformed two stations, one in the low-income Obrero neighborhood of San Juan and one in the town of Utuado, in the remote center of the island. After both installations, Krapels says, the local fire station was the only building with the lights on after dark — outlying and underserved communities are always among the last to receive emergency relief.

“There are parts of the island that are so destroyed that there is no grid,” Krapels says. “There is nothing to fix: The transformers are all burnt, the poles are gone, the wires are laying on the street.”

As much as 80 percent of the island’s high-power transmission lines were destroyed, Bloomberg reported, and even optimistic estimates of repair work have a majority of the island off the grid until late this year.

In the coming months, as communities and companies work to rebuild that infrastructure, there will be an opportunity to make the island more resilient. Companies like Tesla offer one path to less vulnerable electricity infrastructure. Meanwhile, organizations like Resilient Power Puerto Rico emphasize the importance of economic resilience, too. The New York-based founders want to put power in the hands of the island’s residents, modeled after similar efforts in the Rockaways post-Sandy. The nonprofit has ambitions to establish 100 solar towns, a robust green economy, and more electrical independence for all.

“If we’re going to rethink energy in Puerto Rico, let’s really empower people to deploy their own distributed renewable generation and storage,” Krapels says. “The sun is there every day, and it’s going to shine for the next 5 billion years.”

Hurricane Maria crushed Puerto Rico farms. This activist wants to grow resilience through food.

Puerto Rico’s local food movement was in revival mode. While the island struggled with an ongoing debt crisis and a shrinking population, farming was finally growing after a century of decline. More than 1,700 farms opened up since 2013, boosting agricultural jobs by 50 percent. The number of farmers markets tripled over five years; young people were moving back to open up restaurants and food trucks.

Then, Hurricane Maria hit. With 80 percent of the island’s crops ruined, farmers face huge losses from their stripped fields, not to mention their damaged homes.

Tara Rodríguez Besosa’s sustainable restaurant was wiped out by the hurricane. As the local food advocate deals with her own losses, she’s coordinating relief efforts through the Puerto Rico Resiliency Fund to send food and seeds to farmers devastated by Hurricane Maria. In the long term, she’s collaborating with different organizations to create a national sustainable farming proposal plan for Puerto Rico.

The local food movement was fighting against the tide even before the hurricane. Like many islands today, Puerto Rico depends on imported food, which accounts for 85 percent of what residents eat.

I spoke with Rodríguez Besosa to learn how farmers are coping and how Puerto Rico can rebuild its food system with resilience in mind. The interview has been condensed and edited for clarity.

Q. How are farmers doing right now?

A. They just lost their jobs, they just lost their houses. We’re still, even after weeks, getting in contact with them and getting them out of their houses. There have been landslides, there are fallen trees all over, there are bridges that are completely erased. They are not doing so well.

Obviously, we are still in the emergency relief situation, but food takes time to grow. And so we really, really need to see this as an immediate issue. How do we get farmers back to farming? How do we get a roof over their heads? How do we get them seeds? How do we get them tools? Because it takes a while to not only be happier, but to be more autonomous.

Q. What should people should know about sustainable food in Puerto Rico?

A. Just like most everything else, sustainable food is fighting colonization. At the end of the day, the issue is that we are a colony of the United States. And not even most people in the United States know that. The hurricane is unveiling an already humongous problem. We’re dealing with the Jones Act. We don’t vote for the president of the United States. A whole bunch of issues surface once something like a natural disaster happens.

It’s all about creating resilient communities, about creating autonomy, about having power over our food. You know, food is a really powerful tool. So how can we use food to gain independence? We don’t want to receive aid just as much as Trump doesn’t want to give it to us. But we need to grow our own food to be able to get out of this.

Q. Other than the warming-worsened hurricane, how have farmers in Puerto Rico felt the impacts of climate change?

A. We’re an island, so the whole coast of Puerto Rico has definitely been impacted by climate change. If we’re talking about food, the seasons have completely changed. A lot of farmers are finding it very drastic, the changes in atmosphere and climate.

And this is not going to be the last hurricane, right? We just got hit by one hurricane, and then completely destroyed by another one two weeks later.

Q. Tell me about your restaurant.

A. It wasn’t profitable, but it was great! The best ingredients ever!

It was an experiment. I was 26 years old and super-frustrated that restaurants weren’t supporting farmers in the way that I thought that they could. Our kitchen started as a way to prove that you could have a restaurant that used only local, sustainable produce.

But the restaurant was completely flooded during the hurricane and then it got broken into a few times. The restaurant right now is on pause. We decided, let’s focus now on getting these farms back on track.

Q. One farmer I spoke with mentioned the idea that local, organic farms in Puerto Rico could be “hubs of resilience” for communities going forward.

A. They already are, to be honest.

One of our proposals is to start these small community food hubs all along the island, so different farmers can have access to a walk-in cooler with a place where they can sell their food, with a community kitchen that can cook that food and then reach out to the community.

That’s part of a more elaborate plan. Because again, we’re still dealing with a really immediate emergency situation. A whole bunch of deaths have been going on because people are drinking contaminated water. People in the middle of the mountain towns don’t have access to food. A lot of my farmers can’t get out of their homes. We’re trying to get chainsaws through so that people can move trees away. In Puerto Rico in general right now, people are doing it themselves with very little means and very little food.

Q. How are you doing, given everything you’re doing and what’s going on?

A. I’m getting hundreds of emails a day. We’re receiving donations, coordinating fundraising events, coordinating groups of people to go see farms. We’re emotionally drained.

If you work with sustainable food, one of the major things is: “Why do we feed each other?” We feed ourselves and we feed each other this food because it nourishes us and it makes us happy. So how do we give farmers the kind of attention that right now they need? And how do we nourish them during a time when they are doing more physical labor than before?

It’s a long way ahead. Just imagine that a match was dropped over Puerto Rico and it just went poof! all over the place. To have something like this happen really shakes you up.

How a Minimalist Lifestyle Can Add to Your Green Efforts

Shares

You may have seen the term “minimalism” being thrown around a lot lately, especially in the eco-friendly sphere. As more and more people have adopted minimalist lifestyles, the concept has begun to slowly creep to the forefront of our collective consciousness. But what exactly is minimalism? To be honest, it can be a little hard to pinpoint.

Minimalism means different things to different people — it’s unique to the person living it. The truth is, there’s no “one size fits all” to this approach. However, one thing that can be agreed upon is that living as a minimalist is far more earth-friendly than how the majority of Americans are currently getting by. Let’s take a closer look:

What Is Minimalism?

Ranging from apartment-dwelling urbanites to country homesteaders, minimalists come from vast walks of life. They might be single or have a large family, have a house full of treasured items or live out of a backpack. The common ground lies in the opposition to the American ideal of working more to make more, and spending more to have more.

The true essence of minimalism is determining what provides you the most value in life and removing everything that is simply excess. It’s a very intentional way of living that gives rise to positive changes in almost all aspects of life. Being a minimalist means choosing to live your life with great purpose.

Curbing the Consumer Mind-Set

Society’s greatest lie is that a good life is based on the accumulation and possession of as many material items as possible. Massive houses, expensive cars, grand yachts, glittering diamonds — you know, the Instagram-worthy, Kardashian-inspired lifestyle. When we believe that more is better, we fall prey to the notion that money can buy happiness. That’s where minimalism comes in. Minimalism frees us from the all-consuming desire to possess. It sidesteps consumerism and compels us to seek happiness in experiences and relationships. It encourages us to actually live a life instead of buying one.

Now, all this isn’t to say that there’s anything wrong with owning material possessions. It’s more about throwing off the meaning we attribute to said possessions. To put it more plainly, acquiring more stuff shouldn’t come before our health, relationships or personal growth. If owning a house or a car is important to you, that’s perfectly fine. Minimalism is merely a method that supports you in making these decisions more thoughtfully.

When it comes to your possessions, adopting a minimalist lifestyle means being very intentional about what you own and not being distracted by material belongings. While you may want to start your minimalist journey by getting rid of a bunch of stuff, the focus of minimalism shouldn’t be on what you are throwing out, it should instead be on the benefit of removing what doesn’t bring value to your life. Though minimalism sounds like it’s all about having less, there’s actually a lot of “more” that comes along with it. You’ll have more time, more space, more peace and more freedom.

Minimalism Is Eco-Friendly

The basic tenets of minimalism are surprisingly in tune with the eco-friendly way of living. For instance, by making a conscious choice to only purchase what is absolutely needed, you’ll naturally consume less. The less gas, plastic and nonrecyclable materials you use on a regular basis, the fewer nonrenewable resources are used up in their production. Reuse allows you to take this even further, say by borrowing a book from the library instead of buying a new one.

Minimalism makes you more aware of how much waste you generate. Buying less means wasting less; the fewer purchases you make, the fewer boxes, bags and packing materials end up dumped in landfills. What’s more, when you produce less waste, sorting through it for recycling and composting purposes is far easier and more efficient.

Minimalism is helpful in overcoming perceived obsolescence. Perceived obsolescence is when an object is completely functional but is no longer perceived to be stylish or appropriate. It’s rendered obsolete by perception, rather than by function. Minimalism encourages you to purchase goods designed to last for a long period of time, and use them for their entire life span.

Though eighty-sixing excess possessions is a big part of minimalism, the concept goes far beyond what you own. Minimalism should be practiced in all areas of your life — determine what you value most and remove what stands in the way. Apply this to how you spend your time, who you have relationships with, what you eat and so on.

Minimalism, like so many things in life, comes in many forms — it’s a flexible concept. You can choose to adopt the aspects of minimalism that appeal to you most and adapt others to fit your lifestyle. And since it all depends on what adds value to your life in the moment, it’s bound to change over time. After all, what’s meaningful to you in your 20s is not always the same as what’s meaningful to you in your 50s. Just remember, the true aim of minimalism isn’t to deprive yourself of anything, it’s to focus on the things that bring you the most value, cultivate your relationships and live the best life you can.

Wildfire smoke adds apocalyptic hellscape to Disneyland’s attractions.

Sorry to ruin the party, but a report from the Food Climate Research Network casts doubt on recent suggestions that pasture-raised cattle could sequester massive amounts of carbon in the soil.

By nibbling plants and stimulating new root growth, the old argument goes, cows can encourage deeper root networks, which suck up more carbon. Proponents of grass-fed meat have embraced these findings, saying that pasture-raised livestock could mitigate the impact of meat consumption on the environment.

The new report — cleverly titled “Grazed and Confused?” — acknowledges that pastured cattle can be carbon negative, but this depends on the right soil and weather conditions. In most places, according to the report, grazers produce much more greenhouse gas than they add to the ground. It is an “inconvenient truth,” the authors write, that most studies show grass-fed beef has a bigger carbon footprint than feedlot meat. “Increasing grass-fed ruminant numbers is, therefore, a self-defeating climate strategy,” the report concludes.

Fortunately, grass-fed beef is not the only solution being bandied about: Research shows that a small dose of seaweed in livestock feed could drastically reduce methane emissions. And if you really want to reduce your impact on the climate you could, you know, stop eating meat.

Dark Matter and the Dinosaurs

The Astounding Interconnectedness of the Universe

Lisa Randall

Genre: Earth Sciences

Price: $11.99

Publish Date: October 27, 2015

Publisher: Ecco

Seller: HarperCollins


In this brilliant exploration of our cosmic environment, the renowned particle physicist and New York Times bestselling author of Warped Passages and Knocking on Heaven’s Door uses her research into dark matter to illuminate the startling connections between the furthest reaches of space and life here on Earth. Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it might have been dark matter that killed the dinosaurs. Working through the background and consequences of this proposal, Randall shares with us the latest findings—established and speculative—regarding the nature and role of dark matter and the origin of the Universe, our galaxy, our Solar System, and life, along with the process by which scientists explore new concepts. In Dark Matter and the Dinosaurs, Randall tells a breathtaking story that weaves together the cosmos’ history and our own, illuminating the deep relationships that are critical to our world and the astonishing beauty inherent in the most familiar things.
