These fired air pollution experts just did the job the EPA didn’t want them to do

Most people don’t show up to a job after getting fired — but that’s exactly what former members of the EPA’s Clean Air Scientific Advisory Committee did last week.

The group of air pollution and public health experts reconvened to review the latest science and offer recommendations for new air quality regulations, one year after they were fired by then-acting head of the EPA Andrew Wheeler. After days of discussions, the newly renamed Independent Particulate Matter Review Panel issued a letter on Tuesday warning that current regulatory limits pose a threat to public health and urging stricter standards to limit particulate pollution, which has been linked to increased risk of a host of heart and respiratory diseases.

“We wanted to put on the record, here’s all the things that should have happened, had we not been disbanded,” Christopher Frey, the head of IPMRP, told Grist. “And here’s the science advice that the agency would have gotten from us.”

Frey, an environmental engineer and the previous chair of the EPA committee that provides science-based recommendations when the EPA is making air pollution rules, said there was little doubt about the need for stricter regulations. “The evidence is just so strong, it’s kind of mind-boggling,” said Frey.

Federal science has never been perfect — elected officials have always balanced political motivations with government scientists’ findings, and the current administration isn’t the first to pick and choose evidence that supports its agenda. But the state of science is a lot worse than that under Trump: A bipartisan report earlier this month found that federal science is at a “crisis point” due to unprecedented measures that include the EPA’s replacement of panels of experts with researchers affiliated with the industries they regulate.

The IPMRP isn’t just trying to sound the alarm about the Trump administration’s alarmingly anti-science decisions. In addition to raising public awareness, Frey and other members of the panel want their scientific expertise on the record to support any legal cases against the EPA’s new regulations. “No matter what this agency does in terms of rulemaking on particulate matter, given all of the things they’ve changed to the review process, I’m sure they’re going to be challenged in court for making arbitrary and capricious changes to the process itself,” said Frey.

And if you’re still not convinced: The committee within the EPA currently responsible for making scientific recommendations on air pollution wants input from the experts who went on to form IPMRP. In a letter to Andrew Wheeler this April, they suggested that he reinstate the fired scientists, “or appoint a panel with similar expertise.”

Congress is losing a major Republican climate hawk. What now?

Representative Francis Rooney of Florida announced he’s retiring on Saturday, citing frustration over increasing partisanship in Congress and a sense that he’d completed what he set out to do as reasons for his abrupt departure. The surprise decision came just a day after the congressman said he was open to considering articles of impeachment against President Trump (the first House Republican to do so).

“I thought the idea was you came and did your public service and left, you accomplish what you want to accomplish and you left,” Rooney told Fox News. “And that’s what I want to be an example to do. And I’m also tired of the intense partisanship that stops us from solving the big questions that America needs solved.”

While Rooney was in office, he championed a carbon pricing measure and advocated for an offshore drilling ban on Florida’s coast. His departure leaves a climate-shaped hole in the GOP, a party that has developed a pretty severe allergy to established science over the past several years. Rooney is the current co-chair of the Climate Solutions Caucus, a bipartisan group in the House of Representatives whose main objectives are to educate members of Congress about climate change and to push for climate legislation. The group, which formed in early 2016, operates on the premise that bipartisanship on climate and environmental issues is still possible, perhaps once a less science-averse president is in office.

But that caucus took a major hit to its Republican flank during the 2018 midterms, when 21 members lost their seats, including the caucus’ Republican co-chair at the time, Representative Carlos Curbelo, also from Florida. Now, less than a year into his tenure as the new co-chair, Rooney is on his way out.

What does that mean for the future of climate change legislation in the United States? It’s true that with President Trump in office, it’s nigh impossible for climate bills to become law, even if they somehow managed to survive the Senate. Historically, however, major environmental legislation has been successful when both sides of the political aisle fight for it. That’s partly why things like public lands bills and the occasional offshore drilling ban stay put no matter which party controls the White House. But recent political polarization around climate change has wrested the title “conservationist” away from the Republican party and bequeathed it to the Democrats.

Members of the Citizens Climate Lobby, a grassroots environmental group that lobbied for the creation of the caucus, are optimistic that Rooney’s departure does not doom bipartisan climate action, though his sudden retirement did catch the group by surprise. “It’s definitely not something we saw coming,” Andres Jimenez, senior director of congressional affairs for Citizens Climate Lobby, told Grist. “[Rooney] was one of our biggest champions on carbon pricing.”

But Jimenez is confident Republicans will step up to the plate in Rooney’s absence.

He cited recent polling that shows growing support for carbon taxes and a Green New Deal among young Republicans. And he said that Republicans from districts that have been touched by extreme weather and other climate-tinged events are wising up to the fact that voters support climate action.

Not to mention recent news that the Senate is starting up its own bipartisan climate group. That initiative builds off of the work done by the House, Jimenez said. “It’s had a huge impact, not only in the House but now in the higher chamber,” he said, adding: “We believe that there will be champions stepping up to take Representative Rooney’s spot.” He did not, however, name any names.

On July 4, 2012, physicists at the Large Hadron Collider in Geneva madehistory when they discovered an entirely new type of subatomic particle that many scientists believe is the Higgs boson. For forty years, physicists searched for this capstone to the Standard Model of particle physics—the theory that describes both the most elementary components that are known in matter and the forces through which they interact. This particle points to the Higgs field, which provides the key to understanding why elementary particles have mass. In Higgs Discovery, Lisa Randall explains the science behind this monumental discovery, its exhilarating implications, and the power of empty space.

These Girl Scouts are saving wild bees, one ‘hotel’ at a time

Last month, millions of youth activists around the world took to the streets to fight for their right to breathe clean air, drink clean water, and not have to suffer the wrath of the climate crisis.

But that’s not the only way kids are taking climate action into their own hands. In Colorado, the task of saving bees from the consequences of climate change has fallen to the girls who sell us the best cookies. Yes, you heard that right. Over the summer, at a Girl Scout day camp in Denver, Girl Scout troops fashioned tiny homes for wild bees called “bee hotels” to fight the depopulation of bees across the country.

Bee hotels are like birdhouses for wild bees. Since wild bees don’t make honey, they don’t live in hives, but they’re always in need of a suitable habitat. Out in the wild, these bees often nest in holes in fallen logs, dead trees, and broken branches of bushes. But natural habitats can be hard to come by in developed areas, which is where bee hotels come in.

The troops repurposed cardboard boxes, old paper straws, toilet paper rolls, and other materials to create homes for bees in their local community. The project is part of a new initiative called Think Like A Citizen Scientist Journey, in which girls from grades 6 through 12 develop real-world sustainable projects to create change. After some brainstorming and research, the scouts at the day camp chose saving the bees.

Girl Scouts Imani and Aimee with a bee hotel.

“There were times it was hard because there were so many girls and lots of ideas, but we worked together, and it was fun,” said 11-year-old Imani, one of the girls who participated in the project. “We found a way to come to a compromise and work together to make a fun bee hotel so the bees can fit their fuzzy little buns in.”

Working with bees can be a daunting task for kids around Imani’s age. Many children are afraid of bees, because they only know them from the pain of their sting. But Girl Scouts learn to overcome their fears. “I’m afraid of bugs, so it was hard for me to go look at the bees and learn about them,” said Imani. “I’m glad I did. I’m still scared, but I understand how we need bees for food and flowers and that they have a purpose.”

The U.S. has more than 4,000 wild bee species, and 40 percent of them are now facing extinction. The depopulation of bees is due to a number of factors including human activity, pesticide overuse, disease, and the changing climate.

Dennis vanEngelsdorp, an associate professor of entomology at the University of Maryland, College Park, says that bee hotels can play an important role in maintaining bee populations. Bee hotels aren’t only habitats but also a safe haven for bees to lay eggs. If built correctly and well maintained, vanEngelsdorp said, bee hotels can attract new bee species to areas that need pollinators.

“Bees, in general, not just honeybees, are keystone species,” he said. “They’re the ones that keep ecosystems together, they allow for trees to grow, and so, really, they’re cornerstone species.”

After building their bee hotels, the girls went out to install them in green pockets of their community, such as community gardens and the local botanical garden. They also donated one to a local beekeeper who spoke to the troops. “The most interesting thing I learned is probably when you think of bees, you just think of honeybees, but there are so many different types out there,” said Aimee, another 11-year-old Girl Scout.

In addition to helping maintain bee populations, the bee hotel project plays an important role in building a new generation of engaged citizens. “I want to show the girls that they have so many different opportunities to make the world a better place, and that they have many different assets already in their strengths that are all so viable,” said Tiffany Stone, one of the troop leaders.

VanEngelsdorp said it’s important for kids to learn that “every effort counts.” “What you’re seeing is that you need bees to survive, and so who better to be concerned about that than the people who are going to inherit the next generation?” he said. “These efforts are really good because hopefully they set up a lifelong commitment to preserving biodiversity.”

The dark money protecting the ‘worst energy policy in the country’

This story was originally published by Mother Jones and is reproduced here as part of the Climate Desk collaboration.

This summer, Ohio’s beleaguered nuclear and coal plants got a major gift in the promise of a big bailout. Now, the fight over that promise has escalated into one of the most dramatic and bizarre showdowns of the 2020 election cycle.

It all started back in July, when the Ohio state legislature passed a law — called HB6 — that, starting next year, will charge consumers new fees to rescue four struggling power plants. Those charges will eventually add up to a $1 billion bailout for the utility FirstEnergy Solutions’ two nuclear plants, while handing a lifeline to two 1950s-era coal plants owned by another utility, the Ohio Valley Electric Corporation.

Because of the law, Ohio is the first state to reverse its renewable energy standards and efficiency targets, all while funneling more money to coal — a move that has clean energy advocates fuming. Leah Stokes, an environmental political science professor at the University of California at Santa Barbara, called it the “worst energy policy in the country.”

But this it isn’t your typical environmentalists-vs.-fossil-fuel-industry fight. The side opposing the bailout has clean-energy advocates working alongside the natural gas industry. And though the supporters of the bailout include some of the usual suspects — FirstEnergy, coal-reliant American Electric Power, and Duke Energy, and the coal baron and Trump donor Robert Murray — they have also marshaled a mysterious string of deep-pocketed advocacy groups.

A bit of history: The fight dates back to at least 2014, when FirstEnergy pitched a bailout to Ohio’s utility regulator. FirstEnergy went bankrupt in 2018, around the same time it was urging the Trump administration to use emergency powers to save nuclear and coal. (The Department of Energy considered that proposal, but ultimately it went nowhere.) By early 2019, though, FirstEnergy saw a window of opportunity in the Ohio legislature and spent $1 million lobbying on the bailout law. According to an analysis by the Columbus Dispatch, it contributed almost $1 million to state candidates in the 2018 cycle, including $25,000 to help elect Larry Householder as the new speaker of Ohio’s House.

As soon as the law was passed in July, opponents formed a coalition called Ohioans Against Corporate Bailouts. The group, which aims to gather the 265,774 signatures required to get the referendum on the ballot in the 2020 election, hasn’t yet disclosed its funding, but observers suspect that it mostly comes from the renewable energy industry and natural gas companies.

In response, the law’s supporters have waged an unprecedented “all-out deceptive effort to prevent the issue from getting on the ballot,” says Dave Anderson who has tracked developments for the watchdog think tank Energy and Policy Institute.

In addition to FirstEnergy, a number of shadowy groups have materialized to oppose the referendum. Here’s a quick rundown of the major players:

Protect Ohio Clean Energy Jobs bought $10,000 in ads to target Facebook users, directing them to remove their signatures from the petition supporting the referendum. In the ads, it claims that repealing the law would “kill Ohio clean energy jobs.”
Generation Now, a group that does not disclose its donors, hired the petition firm FieldWorks, which has traditionally worked with Democratic clients. The referendum campaign claims that FieldWorks staff have harassed and allegedly paid off their workers, and firms allegedly deploying “petition blockers” to discourage people from signing onto the referendum. In one case, a confrontation between Fieldworks employees and petition workers escalated to the point where the police were called. Generation Now has rejected those allegations as “vague and unsubstantiated.” Generation Now spokesperson Curtis Steiner added that “Fieldworks has been operating in a very professional manner.” He noted that the employee associated with the incident was dismissed.
Ohioans for Energy Security has flooded local networks with a 60-second ad in which a narrator warns viewers that signing the referendum petition would help the Chinese government, as it’s “quietly invading our American electric grid.”

Thousands of Ohioans received mailers from the same group warning, “Don’t give your personal information to the Chinese Government! Don’t sign their petition attacking House Bill 6!”

The claim, based on the fact that some gas plants received funding from the Industrial and Commercial Bank of China, has been roundly debunked. The ads neglect to mention the funding from other major global banks, or that FirstEnergy has loans from the same bank. “We have pretty strong regulation of utilities that would prevent foreign governments from controlling them,” David Dollar, a senior fellow at the Brookings Institution, told the Cincinnati Enquirer.

“These ads are some of the most bizarre and xenophobic I’ve ever seen in relation to energy, electricity, and climate,” says Director of Sierra Club’s Beyond Coal Campaign Mary Anne Hitt.

While the groups opposing the referendum don’t disclose their funding, the Energy and Policy Institute has found links between several of them and FirstEnergy. For example, Protect Ohio Clean Energy Jobs appears to share an address with two lobbyists that FirstEnergy hired to pass HB6.

The Dayton Daily News recently reported that Ohio Attorney General David Yost is investigating some of these allegations of harassment and intimidation. His investigation includes a charge that the opposition has tried to buy off firms working with the referendum for as much as $100,000, which would be considered a felony under state law.

FirstEnergy has neither denied nor confirmed its role in the campaign to scuttle the referendum, instead maintaining that the referendum is unconstitutional and “inherently misleading and confusing to Ohio voters.”

Gene Pierce, a spokesperson for the referendum’s main support group, Ohioans Against Corporate Bailouts, admits that the efforts by the law’s supporters have slowed the signature-collecting process and “driven up the price to hire people.” The referendum has only recently launched a website and an ad campaign that fight back.

If the referendum fails, the outlook for Ohio’s clean-energy advocates could be bleak. The state is the third-biggest consumer of coal in the country. Nuclear power, which provides 15 percent of the state’s electricity, is the state’s biggest source of carbon-free energy. In 2018, the state got a measly 2.5 percent of its power from solar, wind, and biomass — making it one of the lowest users of renewable energy in the country.

Beyond the coal plants the new law helps directly, FirstEnergy has hinted that the extra money from the bailout may help it reverse its plan to close down one of its coal plants. The true cost of the bailout could be higher as coal becomes more unprofitable. All told, “there’s more money in the Ohio law to bail out dirty old coal plants than to support carbon-free nuclear power,”Stokes says.

Sierra Club’s Mary Anne Hitt echoed those concerns. She called the effort to uphold the bailout “one of the most extreme and also aggressive efforts like this that I have ever seen.” She added, “Unfortunately, it’s regular Ohioans who end up paying the price.”

Seller: W.W. Norton & Company, Inc.


Nothing is more memorable than a smell. So why do we persist in dismissing the nose as a blunt instrument? Smell is our most seductive and provocative sense, invading every domain of our lives. We can identify our relatives, detect the availability of a potential mate, sniff out danger, and distinguish between good and bad food just with our noses. In this surprising and delightful book, Lyall Watson rescues our most unappreciated sense from obscurity. He brings to light new evidence concerning Jacobson's Organ: an anatomical feature discovered high in the nose in 1811 and dismissed for centuries as a vestigial ghost. Yet recent research has shown Jacobson's Organ to be an incredibly influential pheromonal mechanism that feeds the area of the brain affecting our awareness, emotional states, and sexual behavior. Following the seven classes of smell devised by the pioneering botanist Carl Linnaeus in his Odores Medicamentorum, Watson examines the roles of smell and pheromones in humans, plants, and animals. He reveals the curious ways in which trees communicate their distress, the olfactory abilities of feral children, the bond we have with our offspring, the psychosexual effects of perfume, and the link between smell and memory formation. Jacobson's Organ unlocks the door to the strange world of this mysterious sense.

The Soil Will Save Us

How Scientists, Farmers, and Foodies Are Healing the Soil to Save the Planet

Kristin Ohlson

Genre: Nature

Price: $1.99

Publish Date: March 18, 2014

Publisher: Potter/Ten Speed/Harmony/Rodale

Seller: Penguin Random House LLC


Journalist and bestselling author Kristin Ohlson makes an elegantly argued, passionate case for "our great green hope"—a way in which we can not only heal the land but also turn atmospheric carbon into beneficial soil carbon—and potentially reverse global warming. Thousands of years of poor farming and ranching practices—and, especially, modern industrial agriculture—have led to the loss of up to 80 percent of carbon from the world's soils. That carbon is now floating in the atmosphere, and even if we stopped using fossil fuels today, it would continue warming the planet.  As the granddaughter of farmers and the daughter of avid gardeners, Ohlson has long had an appreciation for the soil. A chance conversation with a local chef led her to the crossroads of science, farming, food, and environmentalism and the discovery of the only significant way to remove carbon dioxide from the air—an ecological approach that tends not only to plants and animals but also to the vast population of underground microorganisms that fix carbon in the soil. Ohlson introduces the visionaries—scientists, farmers, ranchers, and landscapers—who are figuring out in the lab and on the ground how to build healthy soil, which solves myriad problems: drought, erosion, air and water pollution, and food quality, as well as climate change. Her discoveries and vivid storytelling will revolutionize the way we think about our food, our landscapes, our plants, and our relationship to Earth.

SUVs are back, and they’re spewing a boggling amount of carbon

How can we end our love affair with sport utility vehicles?

Sure, I get it: They carry more people than sedans, and they look cooler than minivans. But consider the facts. A new analysis from the International Energy Agency shows that there are 35 million more SUVs on the road today than in 2010. The number of electric vehicles increased by just 5 million in the same time period. The result: The business of driving humans around is guzzling more gas. So, while greenhouse gas pollution from regular passenger vehicles actually declined since 2010, emissions from SUVs and trucks have increased enough to wipe out those gains, and then some. SUVs, counted alone, are now warming our planet more than heavy industry.

These gas guzzlers could single-handedly eliminate the possibility that the world achieves the climate goals set in Paris in 2016 by insuring that transportation emissions continue to swell. The new IEA analysis concludes: “If consumers’ appetite for SUVs continues to grow at a similar pace seen in the last decade, SUVs would add nearly 2 million barrels a day in global oil demand by 2040, offsetting the savings from nearly 150 million electric cars.”

If you aren’t motivated by the long-term threat of climate change, perhaps you may learn to dislike SUVs if they threaten to kill you. As Kate Yoder pointed out, every one of these vehicles that goes on the road makes the world more dangerous for everyone but the people in them. Pedestrian deaths have reached the highest levels in decades, thanks largely to the influx of bigger vehicles packing heavier punches.

So more deaths and more emissions. We got a preview of this trend in recent numbers coming out of California, where SUVs are also threatening to leave state climate goals broken and bleeding into the gutter.

The fact that beefy vehicles make their drivers a little safer, while endangering everyone around them is a hint as to why it’s been so hard to end our toxic relationship with SUVs. The people making the choice reap the benefits, while everyone else bears the cost. That’s the larger problem popping up here, in the form of surging SUV sales. It’s the problem that runs, and ruins, the world.

New study pinpoints the places most at risk on a warming planet

As many as five billion people will face hunger and a lack of clean water by 2050 as the warming climate disrupts pollination, freshwater, and coastal habitats, according to new research published last week in Science. People living in South Asia and Africa will bear the worst of it.

Climate activists have been telling us for a while now that global warming isn’t just about the polar bears, so it’s hardly breaking news that humans are going to suffer because nature is suffering. But what is new about this model is the degree of geographic specificity. It pinpoints the places where projected environmental losses overlap with human populations who depend on those resources and maps them with a nifty interactive viewer.

This model identifies not just the general ways climate change harms the environment and how people will feel those changes, but also where these changes will likely occur, and how significant they’ll be. It’s an unprecedented degree of detail for a global biodiversity model.

Patricia Balvanera, a professor of biodiversity at National University of Mexico who wasn’t involved in the study, said the new model “provides an extremely important tool to inform policy decisions and shape responses.”

The model looks at three specific natural systems that humans benefit from: pollination (which enables crops to grow), freshwater systems (which provide drinking water), and coastal ecosystems (which provide a buffer from storm surges and prevent erosion). Using fine-scale satellite imagery, the team of scientists mapped predicted losses to these natural systems onto human population maps. The resulting map allows you to see how many people could be impacted by environmental changes, and where.

“We were specifically trying to look at how nature is changing in delivering [a] benefit, and then where it overlaps with people’s needs,” said Rebecca Chaplin-Kramer, the lead scientist at the Natural Capital Project, a Stanford University-based research group that produced the study.

To understand why the Natural Capital Project’s model is groundbreaking, you need to understand a little bit about past attempts to gauge how the environmental effects of climate change will impact people. It’s a pretty hard thing to do — natural processes are interconnected systems, and many of the ways that humans benefit from these natural processes (what scientists call “ecosystem services” or “nature’s contributions to humanity”) aren’t obvious.

“The real challenge, with nature’s contributions to people, is that it benefits us in so many ways that it’s sort of mind-boggling,” Chaplin-Kramer said. “It’s just so abstract that it tends to be disregarded.”

The Natural Capital Project’s model was initially intended to support the massive U.N. biodiversity report released this spring. That report coalesced 15,000 scientific studies into the most comprehensive survey ever done of how climate change threatens global biodiversity — science-speak for “every living thing.” Even if you didn’t read the whole thing, you probably saw headlines like “One million species at risk of extinction, UN report warns.” The IPBES report included a 200-odd page chapter that laid out how all the different things we could see happen to nature will affect people — depending on how humanity reacts in the next few decades to the climate crisis.

But the IPBES report bumped up against one of the biggest challenges when it comes to quantifying nature’s contributions to humankind: Most occur on a local scale. “Spatial context really matters,” said Chaplin-Kramer. “It’s not just the total amount of nature we have, but where we have it, and if it’s in the place where it can deliver the most benefits to people.”

Bee pollinator habitats, for example, only provide benefits to people if they’re within a few miles of the farms that grow our food. Plants that filter nitrogen out of a stream are only “useful” for humans if they’re downstream of the pollution source and upstream of the population. So while the IPBES was able to offer lots of predictions about the aggregate consequences of biodiversity loss — e.g., food supplies will suffer as we lose habitats for bees — they weren’t able to say specifically where they’d occur.

The new model does more than illustrate a problem with great detail — the framework behind it also has the potential to be a powerful tool for avoiding the worst effects of climate change. It could help people prepare for the catastrophes it forecasts.

Unai Pascual, a lead author of the IPBES report and co-author of the Science article, sees this model as taking the IPBES report’s findings a step further, translating a conceptual framework “into something that really can be applied.”

Scientists and non-scientists alike are interested in understanding how to maximize the benefits provided by nature. Just this week a study published in Science Advances found that biologically diverse fields yielded more crops than farms practicing monoculture. Iowan farmers are finding that planting strips of land that mimic native prairies has a range of benefits. In China, a national “Ecological Redline Policy” takes ecosystem services into account in zoning decisions.

These sorts of programs will be more necessary as climate change continues to threaten ecosystems around the world, and policymakers and businesses are increasingly looking to scientists for information about how to protect the natural resources humans need most.

Chaplin-Kramer’s team is working with the World Bank to develop a “Natural Capital” index so that countries can track the condition of their natural resources. They’re also working on an optimization framework to figure out which interventions will have the greatest impact. That will help policymakers use this information to implement conservation policies in the places where, as Chaplin-Kramer put it, “you can get the most bang for your buck.”
