The esteemed scientist \u2013 who has long banged the climate drum and now leads a project that could lower the Earth\u2019s temperature \u2013 is perhaps the world\u2019s leading botanist and is on the cusp of something so big that it could truly change our planet.<\/p>\n
She\u2019s also a woman in her 60s who is fighting a disease sapping her very life. In 2004, Chory was diagnosed with Parkinson\u2019s, which makes the timetable for success all the more tenuous.<\/p>\n
\u201cWe\u2019re trying to do something that\u2019s a huge, complicated thing even though it sounds so simple,\u201d Chory says. \u201cPlants evolved to suck up CO2 and they\u2019re really good at it. And they concentrate it, which no machine can do, and they make it into useful materials, like sugar. They suck up all the CO2, they fix it, then it goes back up into the atmosphere.\u201d<\/p>\n
She is now working to design plants capable of storing even more carbon dioxide in their roots. Her Ideal Plant project uses gene editing \u2013 via traditional horticulture and Crispr \u2013 to do so. On a large scale, this could suck enough carbon out of the atmosphere to slow down climate change.<\/p>\n
This concept basically splices the genes of regular crops and everyday plants like beans, corn and cotton, with a new compound that makes them absorb more carbon. Their roots then transfer it to the soil to keep it there.<\/p>\n
This approach essentially supercharges what nature already does.<\/p>\n
\u201cI get worked up when I talk about the project,\u201d Chory tells me in an office at the Salk Institute, a revered bio research campus at the edge of the Pacific Ocean in southern California. Her desk is full of posies, awards, family photos and framed magazine covers from science journals. \u201cWe have to find a way to take CO2 out of the atmosphere and I think plants are the only way to do that affordably,\u201d Chory says.<\/p>\n
\u201cI feel like I have the weight of the world on my shoulders,\u201d she says, letting out a laugh. \u201cIt is a lot of pressure.\u201d<\/p>\n
Born in Boston to Lebanese parents, the third of six children, Chory received a PhD studying photosynthetic bacteria at the University of Illinois. She spent her postdoctoral years as a Harvard Medical School researcher, then joined the institute in 1988. Along the way, she\u2019s discovered how plants respond to everything from light and environment to how they regulate size and growth.<\/p>\n
\u201cIt\u2019s a philosophical issue, too,\u201d she says, explaining why so many kick the can of global warming. \u201cIf I take pain now, maybe my great-grandchildren might see a benefit. People choose no pain now, that\u2019s why we\u2019ve done nothing about climate change.\u201d<\/p>\n
Every now and then as we speak, Chory\u2019s symptoms pop up like an uninvited guest, another stark reminder of time. Struggling to maintain control and ever aware of the implied humor in her movements, she doesn\u2019t shy from the elephant in the room.<\/p>\n
\u201cWhen I get excited I really get moving,\u201d she mock-apologizes, letting out a coy chuckle. \u201cI\u2019m a lot better on Saturdays.\u201d She pauses, collects her thoughts. \u201cThat\u2019s why I want to do something that won\u2019t cause pain to people. You never know when you\u2019re making a global change. I don\u2019t know if we can do it, but we have to try.\u201d<\/p>\n
An \u2018even if\u2019 scenario
\nTemperatures are already at alarming levels even if we reach the Paris agreement of curbing a rise of 2C. The world is headed for major upheaval, it\u2019s merely a question of the scale. If we have any chance as a species, Salk contends, it\u2019s with big ideas like this.<\/p>\n
Right now, the institute is negotiating with seed companies and prepping tests on nine agricultural crops to introduce Ideal Plants on farms around the world. Field-testing begins later this year with wheat, soybeans, corn and cotton.<\/p>\n
Developing these Ideal Plants is step one in the Harnessing Plants Initiative, which amplifies root systems and production of suberin \u2013 which is essentially cork, or the rind on your cantaloupe, the magic key to plants holding more of that carbon \u2013 before transferring these genetic traits to row and cover crops. Given the right resources, and funding, prototypes of each crop are expected to be ready in the next five years.<\/p>\n
A $2m gift by Howard Newman, a Salk board member and private equity veteran who has invested in oil and gas, jump-started the project last June. In April, Salk received a TED Audacious grant totaling $35m to support the plan.<\/p>\n
Chory says these new plants will have deeper and stronger root systems that will also stop erosion, another byproduct of warming temperatures, which will make soil more healthy and boost production. When normal plants die, they release large amounts of CO2 back into the air; when Ideal Plants die, significantly less CO2 will be re-released due to more carbon being stored in deeper roots and soil for longer periods, and suberin\u2019s natural ability as a carbon polymer to resist short-term decomposition.<\/p>\n
The first two meters of the Earth\u2019s soil holds over three times the amount of carbon as the atmosphere, and can hold even more. Fossil fuel use was predicted to rise nearly 2% last year. Each year, we produce 18 more gigatons of CO2 than the Earth can currently handle; Salk believes their solution can achieve as much as a 46% annual reduction in excess CO2 emissions produced by humans.<\/p>\n
It\u2019s an extremely ambitious idea full of so many unknowns \u2013 how to get global buy-in from farmers, how many years will it take for plants to reach maturity and will it then be too late, how will mother nature react to such genetic modification and how will these crops taste \u2013 that none of Salk\u2019s brains have the answers to.<\/p>\n
The institute was founded in 1960 by Jonas Salk, a biologist who discovered the cure for polio in 1955, two years before my own father\u2019s identical twin died of the disease in communist Romania, a place where politics kept science at bay.<\/p>\n
Standing at the edge of the seaside campus designed by Louis Kahn, a sprawl of ominous cement towers and dramatic ocean views, it all feels straight out of the mind of Philip K Dick. Part Gattaca, part Logan\u2019s Run, it\u2019s easy to see why numerous films have been shot here.<\/p>\n
But there\u2019s also an optimism in these labs that feels so far from the stark structures and climate narrative I\u2019m used to. Many scientists have told me their role is something akin to historian, documenting the last days of a species or system. Not so here.<\/p>\n
\u201cThere is hope in dreams, in imagination and in the courage of those who dare to make dreams into reality,\u201d Jonas Salk once said.<\/p>\n
Inside these modernist blocks, they\u2019re dreamers too, but rooted in reality. The biological research center, funded by government grants and private donors, has spent decades inching towards cures for everything from cancer to Alzheimer\u2019s. In 1968, Robert W Holley, Salk Cancer Center\u2019s founding director, won a Nobel prize; in 1975, Institute staff won another Nobel, and again in 1977 and 2002.<\/p>\n
More recently, Chory was awarded a $3m breakthrough prize for discovering how plants optimize their growth, development and cellular structure to transform sunlight into chemical energy.<\/p>\n
I see the optimism on a tour with Dr Joseph Noel, a biochemist focused on harnessing suberin, the project\u2019s linchpin. He shows me seed-planting robots, which can bang out a day\u2019s work in the time it would take a human weeks; state-of-the-art grow rooms capable of simulating almost any environmental condition; greenhouses sitting atop dramatic bluffs. All the while he breaks down the importance of cork. \u201cIt\u2019s a spongy barrier that helps a plant regulate water coming in and out, gas exchange coming in and out. Think of it like a protective plastic around certain cells in the plant.\u201d<\/p>\n
The institute\u2019s founder, Jonas, once said \u201cour greatest responsibility is to be good ancestors,\u201d and I think about the quote\u2019s relevance as Noel shows me rows of simulation rooms full of cattails, marsh grasses, Lotus japonicus legumes and weed-like Arabidopsis thaliana, all in various states of growth as LEDs shine and humid air blasts while I take notes.<\/p>\n
\u201cInstead of just growing in a greenhouse or artificial lights in a lab, we wanted to have the ability to simulate a particular climactic zone: quality of light, seasonal changes, cloud cover, temperatures,\u201d Noel says.<\/p>\n
Since Arabidopsis \u201ccan go from seed to seed in six weeks\u201d and its genome is entirely sequenced and resembles so many other species, the little mustard flower has become the project\u2019s veritable Rosetta Stone.<\/p>\n
\u201cIt\u2019s very easy to change the genetics of it on a massive scale,\u201d he continues. \u201cIf we change a particular gene, we can find out if the roots get deeper, do they get more extensive, does the suberin content change. Their early ancestors have been doing photosynthesis for about 2.8bn years.\u201d<\/p>\n
Without plants, life as we know it wouldn\u2019t exist. The question is whether these ones will become our saviors.<\/p>\n
Genetically modified plants remain a tough sell
\nThere\u2019s a growing field of carbon dioxide removal projects which include machines pulling C02 out of the sky, known as direct air capture. There\u2019s Bill Gates-backed Carbon Engineering and the Zurich startup Climeworks, and about 20 commercial carbon capture and storage facilities worldwide, but they\u2019re price prohibitive.<\/p>\n
There have been notable failures: Sir Richard Branson tried a $25m prize for carbon removal but never found a solution. Carbon removal initiatives are also criticized for preserving the status quo and big energy business models.<\/p>\n
\u201cUltimately, we all know that humanity\u2019s response to climate change will, as the Ideal Plant project states, make or break our future,\u201d says David Stern, the president and CEO of the Boyce Thompson Institute, a leading plant research facility in New York, who calls Chory a fearless, creative and open-minded scientist. \u201cGiven the complexities and scale of the problem, many types of solutions will be needed. Sequestration is undoubtedly one of them.\u201d<\/p>\n
One big problem, Stern notes, is winning hearts and minds. Genetically modifying organisms saving the planet might be a tough sell in an era when GMO has become the antithesis for the green, organic movement.<\/p>\n
\u201cWhile they are not proposing traditional transgenic lines nor are they proposing to do their work in food crops, the issue will still come up,\u201d Stern adds.<\/p>\n
Chory maintains that plants have been modified for millennia \u2013 selecting the best strains to cultivate and taking a hand in their development is a form of genetic modification, after all \u2013 and the nutritional and yield values of such tweaked products still outweigh the drawbacks. Salk doesn\u2019t introduce foreign genetic material in its plants, unlike many GMO products. The European Union outlawing modified organisms, plus crops with Crispr traits (as a result, the plants might not make it to the EU). Another issue is seed pricing and getting it to farmers around the world, so the wide-scale use is in question.<\/p>\n
\u201cAs with any GMO crop the big question is how do the changes affect nutritional quality and whether small farmers in developing countries would be able to buy the seeds on a large enough scale to make a difference?\u201d wonders Dan Wenny, a senior biologist who studies land-bird seed dispersal at the San Francisco Bay Bird Observatory.<\/p>\n
Right now, the Mississippi delta in Louisiana is a test zone for a first batch of Ideal Plants in the wild, a major step to see if improved root systems can mitigate sea level rise. Still, Salk researchers are sober to the odds.<\/p>\n
\u201cAny restoration effort, unlike our Arabidopsis that can grow from seed to seed in six weeks, these systems you plant them and then you wait. You wait a long time,\u201d Noel laments. \u201cWe can\u2019t afford to have these experiments not work.\u201d<\/p>\n
Are we past the point of no return? \u201cThe world\u2019s not going to be the world we live in right now,\u201d Chory says. \u201cI don\u2019t know if we\u2019re going to eliminate the whole human species, but I think if we don\u2019t do something soon we will go that route. The misery index of humidity plus the heat will get so high mammals can\u2019t live.\u201d<\/p>\n
The Union of Concerned Scientists says the tipping point is here.<\/p>\n
\u201cI don\u2019t think it\u2019s here yet,\u201d Chory counters. Still, she concedes that \u201cmigration is already happening. Canada is going to make out well in this. The United States is not. We\u2019re going to have a lot of changes in our agriculture.\u201d<\/p>\n
She adds: \u201cThe farmers are the ones we really have to convince. We can\u2019t continue to farm the way we farm any more. It can feed 8 to 10 billion people but 50 years from now, there won\u2019t be any good soil left so you\u2019re just putting the disaster off.\u201d<\/p>\n
Chory glances at a picture of her daughter, Katie.<\/p>\n
\u201cLook at me, I\u2019m 64 years old. I\u2019m not going to be around to see this project go to fruition, I\u2019m not going to be working at Salk, probably. That urgency is there. The climate urgency is there. Every week there\u2019s a new climate disaster. How can we get there? We can\u2019t really get there any faster. I don\u2019t know if we can do it, but I want to be part of the solution. I don\u2019t just want to sit around and complain.\u201d<\/p>\n
