Can we stop stupid politics from ruining carbon farming?

It seems like every Democratic presidential candidate wants to get farmers sucking carbon out of the air and sticking it in the ground. Call it regenerative agriculture, carbon farming, soil carbon sequestration, but, boy have the candidates found an idea they love. Among the more popular names, Elizabeth Warren, Pete Buttigieg, Bernie Sanders, Beto O’Rourke, and Joe Biden, have included it in their platform. Kristen Gillibrand, Tim Ryan, and Amy Klobuchar have also said they want to pay farmers to catch carbon.

The science is straightforward enough. Planting a cover crop after harvest, when the acres might be bare and vulnerable to erosion, helps capture carbon. Farmers can keep that greenhouse gas in the ground if they stop plowing, because turning over the dirt with a plow releases soil carbon. These are relatively simple practices that many farmers have already adopted.

We’ve treated soil-science like dirt for too long, so it’s nice that it’s finally getting the chance to star in shovel-ready (sorry) national policy proposals. But there’s still reason for caution: Politics has a way of distorting science.

Look back twenty years and everyone was excited about biofuels: Presidential candidates talked about how we could grow green fuel provide new markets for farmers, while freeing ourselves from foreign fossil fuels. And the plants would suck carbon from the air. What’s not to love?

Starting in 2005, the government enshrined market mandates to help people start turning crops into fuel. Farmers cut down rainforests in Southeast Asia to grow oil palm for biofuel. Although the new market for corn and soy beans was great for Midwestern farmers, it was awful for those trying to stop erosion, preserve prairie habitat, and shrink the deadzone in the Gulf of Mexico. At this point, it’s nearly impossible to tell if biofuels are any better or worse for the climate than gasoline.

So if we want to learn from history, rather than repeat it, we’ll tamp down the hyperventilation over soil carbon, make sure we get the numbers right, and look out for unintended consequences.

Right now, the presidential candidates are talking in vague terms. Sanders’s plan, for instance, says the government will “pay farmers $160 billion for the soil health improvements they make and for the carbon they sequester.” O’Rourke’s just says he wants to “allow farmers and ranchers to profit from the reductions in greenhouse gas emissions they secure.” But as these ideas morph from Iowa stump speeches to actual legislation, keep an eye out for some potential stumbling blocks:

It’s uneven. The amount of carbon you draw out of the atmosphere with, say, your winter cover crop depends on how long your fields are frozen, how sandy your dirt is, how many worms are squirming in your soil … and that’s just for starters. So if the point is to fight climate change, proposed policies should pay farmers for results (the amount of carbon dioxide they take out of the air), rather than paying for practices (like planting a cover crop), said Jonathan Sanderman who studies soil carbon and climate change at Woods Hole Research Center.

Returns diminish. As soils “fill up” with carbon it gets harder to add more. Soil gets saturated. Navin Ramankutty, who studies global food systems at the University of British Columbia, thinks of soil like a bathtub: If there’s more water coming through the faucet then leaving through the drain, the water rises. Replace “water” with “carbon” and you get the idea. Eventually the carbon is going to start spilling over the top of the tub. “So, while carbon farming is certainly a useful measure to mitigate carbon emissions, it’s a solution with a finite lifetime,” Ramankutty said.

Keep it in the ground. Once carbon is in the ground, it doesn’t just stay there. Soil is churning with worms, fungi, bugs, and bacteria that eat up, transform, and release carbon back into the air. It really is dynamic, like Ramankutty’s bathtub. If farmers decide to plow up fields after years of sequestration, it would release a lot of the stored carbon. “How you deal with this is clearly a tricky policy problem,” Sanderman said. Perhaps, when agreeing to take money for carbon sequestration, farmers would have to accept restrictions on their land for the next decade.

It could crowd out other ideas. How much will carbon farming cost taxpayers, and are there other ideas that — for the same cost — would take even more greenhouse gases out of the air? Expanding forests, growing seaweed, or scrubbing carbon from the air might make more sense in some cases. Could we replace a coal plant with clean energy for the same amount of money and prevent more emissions in the first place? The danger of the latest sexy policy is that it tends to take precedence in every context, not just the ones in which it makes the most sense.

Candidates break hearts. Some of the candidate’s proposals use unrealistically large numbers for the carbon that farming could suck up, said Mark Bomford, director of Yale’s Sustainable Food Program. “I suspect this overstatement has less to do with misunderstanding the science, and more to do with what inevitably happens to communication of the science when it enters the arms race of political rhetoric,” Bomford said.

It just sounds better to say that an acre of farmland can suck up 25-60 tons of carbon a decade, as ex-candidate Jay Inslee did, then to say 7.4 tons per decade, which is the consistent average, Sanderman said.


All this is to say we ought to be a little wary of ambitious soil-policy solutions for climate change. Anyone who says we’ve figured out carbon farming (or whatever your buzzword of choice) deserves your skepticism. But the nice thing about about these proposals is that minimizing tillage, planting cover crops, and the other practices that store soil carbon are generally good for the environment — even if they don’t do as much to stem the climate crisis as advertised.

An easy, cost-effective way to address climate change? Massive reforestation.

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

As the implications of climate change become starker and the world faces up to a biodiversity crisis that threatens humanity’s existence, a group of campaigners from across the world are saying there is one clear way to get us out of this mess, but that governments are ignoring it.

In an open letter published in the British newspaper, The Guardian, the group tells governments that the best and cheapest way to avert a climate catastrophe is to heal nature by restoring and replanting degraded forests and by better conserving the natural world.

“Defending the living world and defending the climate are, in many cases, one and the same. This potential has so far been largely overlooked,” say the 23 signatories to the letter.

“We call on governments to support natural climate solutions with an urgent program of research, funding, and political commitment,” they added.

Vast amounts of carbon can be removed from the air and stored by restoring ecosystems razed by palm oil plantations, cattle ranching and timber, and fish production, the letter says. The 23 signatories include the  teenage school climate strike activist Greta Thunburg, authors Margaret Atwood, Naomi Klein, and Philip Pullman, U.S. climate scientist Michael Mann, and environmental campaigner Bill McKibben.

“The world faces two existential crises, developing with terrifying speed: climate breakdown and ecological breakdown. Neither is being addressed with the urgency needed to prevent our life-support systems from spiralling into collapse,” say the signatories.

They call for the defense, restoration and reestablishment of forests, peatlands, mangroves, salt marshes, natural seabeds, and other crucial ecosystems, to remove and store large amounts of carbon from the air. The protection and restoration of these ecosystems can help minimize a sixth great extinction, they say.

The group says that nearly a third of the greenhouse gas reductions needed to hold temperatures to a 1.5 degrees C (2.7 degrees F) rise can be provided by the restoration of natural habitats. But natural solutions are calculated to have attracted just a small fraction of the funding so far committed, according to journalist and author George Monbiot, one of the signatories.

Technology alone cannot solve climate change, Monbiot wrote in The Guardian. Much of the technology proposed to capture carbon is expensive and could pose problems at scale. The cheapest and surest approach, he wrote, is to restore natural forests and allow native trees to repopulate deforested land.

Regenerating and conserving nature to address climate change is expected to be a central recommendation of next month’s landmark study of the state of the natural world, compiled by hundreds of scientists. The United Nations-backed report is expected to confirm that nature is in rapid decline in many regions, with ecosystems on the point of collapse.

Protecting and restoring natural forests is seen as vital. Trees suck carbon dioxide from the air and store it. Nearly one-quarter of all the emissions reductions pledged by countries in the 2015 Paris agreement could come from tree planting and restoration. The U.N. has challenged countries to restore 865 million acres of farm and forest land by 2030 — an area bigger than India. And countries are responding.

Initiative 20×20, an international effort, hopes to restore 49 million acres by 2020 in Latin America and the Caribbean. And the multicountry African Forest Landscape Restoration initiative intends to restore 247 million acres of degraded forests in Africa by 2030.

Pakistan has just planted 1 billion trees. China plans to create forests totaling the size of Ireland. And in Africa, Ethiopia, Niger, Mali are among countries that strongly back the reforestation of degraded land.

But there’s a snag. A new paper in the scientific journal, Nature, suggests that 45 percent of the land area that nations have so far pledged to allocate for carbon drawdown is being used to for commercial plantations.

There’s a huge difference between restoring natural forests and planting trees for commercial use, for example the large-scale monoculture of oil palms to provide us with the palm oil so ubiquitous in snacks and cosmetics. The latter are less efficient at carbon storage, and in fact release carbon emissions by replacing peatland, as well as being detrimental to wildlife.

These natural solutions also go beyond trees. They include the restoration of peatlands, salt marsh and seagrass. They also mean the protection and recovery of animals like rhinos in Africa, which act as a natural protection against devastating wildfires, and wolves in North America, which some studies suggest could protect forests by controlling populations of animals that feed on plants and trees.

Still, Monbiot cautions: “We don’t want natural climate solutions to be used as a substitute for the rapid and comprehensive decarbonization of our economies. The science tells us both are needed.”

“But,” he continues, “what this thrilling field of study shows is that protecting and rewilding the world’s living systems is not just an aesthetically pleasing thing to do. It is an essential survival strategy.”

California’s battle against climate change is going up in smoke

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

Just a few months ago, climate activists in California were celebrating an impressive victory: New data showed that the state had brought greenhouse gas emissions down to 1990 levels, four years earlier than planned. The win, a cut of emissions to 429.4 million metric tons (the equivalent of taking 12 million cars off the road) was the result of steady decreases in emissions most years.

“California set the toughest emissions targets in the nation, tracked progress and delivered results,” Governor Jerry Brown tweeted. The next step was to cut emissions another 40 percent by 2030 — “a heroic and very ambitious goal.”

But by November, skies across the state were gray. Wildfires were raging, including a blaze which would prove to be the deadliest and most destructive in state history. The conflagrations have set California back: The recent Camp and Woolsey Fires, officials say, have produced emissions equivalent to roughly 5.5 million metric tons of carbon dioxide, more than three times the total decrease in emissions in 2015. Recently, the Department of the Interior announced that new data shows the 2018 California wildfire season is estimated to have released emissions equal to about one year of power use.

California’s wildfire problem

Of course, wildfires are not new to the West Coast. But the kind of vast, devastating conflagrations seen in California in recent years — this fall’s Camp Fire decimated 153,000 acres in the Butte County area and destroyed almost 14,000 homes — are becoming more common. According to the state’s most recent climate assessment, California could see a 77 percent increase in the average area burned in wildfires by 2100.

All this is bad news for a state committed to decreasing its carbon footprint. But California’s official emissions score will not be affected by the extraordinary amount of carbon released during wildfires this year, because the agency that calculates emissions — the California Air Resources Board — considers wildfires to be a part of the earth’s natural carbon cycle. (The ARB is a regulatory body and, as agency spokesperson Dave Clegern noted, “can only regulate what can be controlled.”)

But the agency is looking into ways to better track carbon emissions from conflagrations. Right now, Clegern says, the ARB uses data including the size of the fire and the kind of fuel burned to estimate its carbon footprint. But, he said, scientists don’t currently have a good way to accurately calculate emissions from disasters like the Camp Fire, which burn residential and commercial properties. While those findings won’t be included in the state’s emissions tally, Clegern said it’s still important to gather the data: “We need to know what goes up in the air when these things happen. Our first mission is to protect public health.”

The increasing size of wildfires in California is driven by several factors linked to climate change, scientists say, including a shift in the jet stream that causes the state to suffer more hot, dry spells. The state’s seven-year drought has weakened forests and left millions of acres highly susceptible to lethal attacks from insects like bark beetle. In recent years, more than 100 million trees are estimated to have died statewide. Dry, dead forests are a fire hazard, and they pose a threat so severe that, in 2015, Governor Brown declared a state of emergency and created a task force to identify areas of particular risk. This January, scientists at the University of California-Berkeley reported that the situation was “compounded by the long-established removal” of naturally occurring, frequent, and low-intensity fires in the state’s forested areas, “a key ecosystem process” in hazardous wildfire prevention.

Aside from preventing deadly conflagrations, protecting forests also means preserving the state’s best tool for regulating carbon emissions. By removing carbon dioxide from the atmosphere and storing it as carbon in soil, branches, and tree trunks, forest have historically worked as a “carbon sink” for the state. But research shows that between 2001 and 2010, tree die-off meant California’s forests emitted more carbon than they sequestered.

Wildfires accelerate this process. Conflagrations release carbon into the atmosphere as they burn and, once the smoke has cleared, leave fewer trees to sequester carbon. In the years following a fire, dead trees begin to release their stored carbon back into the atmosphere. And a recent study also showed that forests which burned at high severity suffered worryingly low regeneration rates. In some places, no trees grew back at all.

But the damage doesn’t end there. When a forest is burned for the first time, “between 5 and 20 percent of the carbon goes up,” explained Nic Enstice, regional science coordinator at the state’s Sierra Nevada Conservancy agency. That’s because even a high-severity fire will not incinerate every tree in a forest. But if a second wildfire ravages through an already-burned area, the dead trees are more readily consumed, resulting in even greater carbon release.

The fire season’s growing effect on the state gives scientists all the more reason to study its emissions. “That’s the kind of issue we’re wrestling with now,” Clegern said.

California’s best hope for reaching its ambitious climate goals may lie in technology and rebuilding the state’s dilapidated forests. The state is relying on energy companies like utility giant PG&E to increase purchases of renewable power and invest heavily in burgeoning industries like electric transportation over the next decade. (PG&E, meanwhile, could be on the hook for billions of dollars in fines if an investigation finds the company’s equipment ignited some of California’s recent conflagrations.) Plans are also underway to push harder on forest restoration efforts: In May, the state announced its Forest Carbon Plan, which included a pledge to double the rate of forest rehabilitation to an average 35,000 acres a year by 2020.

“We know that we have to increase the health of our forests pretty significantly over the coming years,” Enstice said.“What we saw in the Camp Fire, the Rim Fire, the King Fire — these are all out of the normal patterns.”

Trump grudgingly signs a bill that stops his border wall from ruining a wildlife refuge.

An investigation by the Associated Press and the Houston Chronicle uncovered more than 100 releases of industrial toxins in the wake of Hurricane Harvey.

The storm compromised chemical plants, refineries, and pipelines along Houston’s petrochemical corridor, bringing contaminated water, dirt, and air to surrounding neighborhoods. Carcinogens like benzene, vinyl chloride, and butadiene were released. In all but two cases, regulators did not inform the public of the spills or the risks they faced from exposure.

The report also found that the EPA failed to investigate Harvey’s environmental damage as thoroughly as other disasters. The EPA and state officials took 1,800 soil samples after Hurricane Katrina in 2005. After Hurricane Ike slammed into Texas in 2008, state regulators studied 85 soil samples and issued more than a dozen violations and orders to clean up.

But post-Harvey, soil and water sampling has been limited to 17 Superfund sites and some undisclosed industrial sites. Experts say this is a problem because floodwaters could have picked up toxins in one place and deposited them miles away.

“That soil ended up somewhere,” Hanadi Rifai, director of the University of Houston’s environmental engineering program, told the AP. “The net result on Galveston Bay is going to be nothing short of catastrophic.”

Seven months after Harvey, the EPA says it’s investigating 89 incidents. But it has yet to issue any enforcement actions.

4 surprising facts about the judge behind California’s climate change trial.

On Tuesday, the court will hear arguments about a California law that tries to clarify the facts that women receive about their reproductive rights. The accuracy of that information becomes increasingly important as environmental disasters — which are growing more, uh, disastrous — endanger women more than men. Women can be better prepared by having full control of their reproductive decisions.

Crisis pregnancy centers are organizations, often masquerading as medical clinics, that attempt to dissuade women from seeking abortions. California’s Reproductive FACT Act, passed in 2016, requires reproductive health clinics and CPCs to post notices advising their clients that the state provides free or low-cost family planning, prenatal care, and abortion; and that CPCs publicize that they are not licensed to practice medicine.

Alliance Defending Freedom, the legal organization representing the centers suing the state of California, claims that the requirements of the Reproductive FACT Act are unconstitutional because they require CPCs to “promote messages that violate their convictions,” Bloomberg reports. The state of California argues that information provided by medical professionals is publicly regulated, and that women who depend on public medical care and are unaware of their options should not be provided with confusing information.

Last February, a Gizmodo-Damn Joan investigation found that women seeking abortion clinics on Google — because, let’s be real, that’s how a lot of us find medical care — could be easily led to CPCs instead, as Google Maps does not distinguish them from real medical clinics.

We’ll be watching this case.
