There are a couple of seemingly contradictory memes rolling around the deep learning field. One is that you need a truly epic amount of data to do interesting work. The other is that in many subject areas there is a ton of data but it's not just laying around for data scientists to snarf up.

On this week's Structure Show podcast, Enlitic Founder and CEO Jeremy Howard and Senior Data Scientist Ahna Girshick address those topics and more.

Girshick, who is our first guest who's worked with Philip Glass and Björk on creating music visualizations, said while there may be scads of MRIs, CAT scans, x-rays created -- they're typically used for their primary purpose -- to diagnose your bum knee, and are then squirreled away in some PACS system never to see the light of day again.

All of that data is useful for machine learning algorithms, or would be, if it were accessible, she said.

Girshick and  Howard agreed that while deep learning -- the process of a computer teaching itself how to solve a problem -- gets better with more data, there's no reason to hold off working with it for data become available.

"While more data can be better I think this is stopping people from trying to use big data inappropriately," Howard said. He cited a recent Kaggle competition on facial key point recognition that's  using 7,000 images and "the top algorithms are nearly perfectly accurate."

The reason companies like Baidu and Google say you need mountains of data is because they have mountains of data available, he said.  "I don't think people should be put off trying to use deep learing just because they don't have a lot of data."

Enlitic is using deep learning to provide medical diagnoses faster and help provide better medical and outcomes for millions of underserved people.

It's a fascinating discussion so please check it out -- Girshick will speak more on what Enlitic is doing at Structure Data next month.

And, if you want to hear what's going on with Pivotal's big data portfolio, Derrick Harris has the latest. Oh and Microsoft makes a bold play for startups by ponying up $500K in Azure cloud credits starting with the Y Combinator Winter 2015 class. That ups the ante pretty significantly compared to what Amazon Web Services, Google and IBM offer. Your move boys.

China has for the first time committed to an absolute target to reduce greenhouse gas emissions, by 7 to 10 percent by 2035. We discuss China’s growing dominance in the global clean energy transition while the current US administration doubles down on fossil fuels.
Also, compared to traditional rooftop solar, “balcony solar” offers renters, apartment dwellers and folks on a tighter budget a much less expensive solar energy starter kit.
Balcony solar is already common in Europe and Asia, and now it’s getting a boost from state legislation in the US.
And members of the late conservationist Jane Goodall’s Roots and Shoots youth organization and the Living on Earth crew share memories of her and gratitude for her enduring gifts to the world.

Facing lost jobs and higher energy prices after the Trump EPA canceled $7 billion in low-income solar grants, a coalition of labor, green and anti-poverty groups is teaming up to fight in court for clean energy jobs and save “Solar for All.” 
Also, one of the most frightening aspects of Halloween is the monstrous amounts of waste it can generate. We share ideas for making Halloween a little more sustainable, from recycling candy wrappers, to composting pumpkins, to thrifting costumes.
And on September 21st, hundreds of people leapt into the Chicago River for the first public swimming event since 1927. We discuss how major projects including green infrastructure have helped clean up the river for both people and wildlife to enjoy.

A recent Human Rights Watch report found that illegal cattle ranching and clearing of the Amazon rainforest has led to the forced eviction of small farmers and indigenous people in the state of Pará, Brazil. We discuss the stakes for the planet and people, as well as possible solutions. 
Also, meat is the biggest single source of carbon emissions from the food system, which is itself responsible for a third of global greenhouse gas emissions. We talk about the gap between reality and coverage of how meat contributes to global warming, as well as effective strategies for encouraging people to choose to eat less meat without trying to force them to do so. 
And David Brancaccio of Marketplace lost his home in the devastating Los Angeles fires this past January only two months after moving in. We check back in with David to hear about his hopes to rebuild with fire-resistant material.

Hurricane Melissa, the strongest storm to hit the Caribbean in modern times, left a wake of destruction in Jamaica, Cuba and Haiti that will take years to recover from. A Jamaican climate physics professor describes the toll of this climate catastrophe, and a meteorologist joins us to explain how the storm grew so ferocious in the blink of a hurricane’s eye.  

Also, Gwich’in Alaska Natives, which consider the land of the Arctic National Wildlife Refuge sacred and local Porcupine Caribou as relatives, are expressing alarm at how renewed prospects of drilling in this fragile environment could upend their world. 

And the Pacific Northwest of the US harbored a serial killer hotspot of sorts in the 1970s, associated with the neurotoxin lead. Seattle-born author Caroline Fraser explores this link in her book Murderland: Crime and Bloodlust in the Time of Serial Killers. She discusses how dangerously high lead exposure from smelters and gasoline may have led to the increase of violence and murders in the region.

The biggest climate negotiations of the year, COP30, are kicking off in Belem in the Brazilian Amazon. Longtime COP observer Jennifer Morgan joins us to preview COP30 and discuss the focus on closing the gap between current greenhouse gas reduction policies and what’s needed to limit warming to a safer level.
 
Also, King Charles III, who leads the Anglican Church, and Pope Leo XIV, who leads the Roman Catholic Church, recently joined in a historic prayer in the Sistine Chapel. This act of unity by these two faith leaders who are also sovereign heads of state was embedded in their shared concern for the environment, or creation.
 
And as one of the strongest hurricanes ever documented in the Atlantic, Hurricane Melissa brought catastrophic damage to Jamaica and Cuba, and an extensive relief and recovery effort is now underway. We talk about the aid efforts, long road to recovery, and importance of building back better.

November’s elections brought victories across the country for state and local Democratic candidates who pledged to address rising energy costs. The challenges of meeting those promises the incoming Governors of Virginia and New Jersey, and Mayor of New York, will likely face.
Also, a recent report warns that the European Alps, Rockies of the Western U.S. and Canada, Iceland, and Scandinavia would lose nearly all ice at 2°Celsius of warming – a threshold we’re currently on track to exceed. 
And in the Peruvian Amazon, the Asháninka people have developed a symbiotic relationship with the local bees, which often lack stingers, and their honey. A new and innovative law in Peru has granted these bees legal rights to help protect them and the indigenous people living with them.

As the host of this year’s UN climate treaty negotiations and home to most of the Amazon tropical rainforest, Brazil led a major advance for forests and their indigenous inhabitants. The new $125 billion fund, with guarantees for investors, will send its profits to countries with documented forest preservation, including some cash going directly to indigenous and local populations. 

Also, we now know about the severe health impacts of tiny airborne particles or PM2.5, thanks in large part to the groundbreaking “Six Cities” study that started in the 1970s. The leaders of that team were Doug Dockery and Arden Pope, and they’re co-authors of the 2025 book, Particles of Truth: A Story of Discovery, Controversy, and the Fight for Healthy Air.

And members of the Living on Earth crew share a few laughs and our favorite Thanksgiving recipes, from pumpkin soup to chouriço stuffing to desserts made with leftover pie crust.

Tropical Forests, Forever? Air Pollution Pioneers, and Thanksgiving Feast Favorites.

Wildfire smoke is fouling air quality across the US with increasing regularity, and it carries a heavy toll. A September 2025 study published in the journal Nature found that every year around 40,000 Americans are dying from wildfire smoke, with more on the way as the planet warms. Air filters, face masks and low-intensity prescribed burning can help protect the public from this growing threat.
Also, around a third of the firefighters who battle wildfires in California are incarcerated, and until recently they were paid just $5 to $10 a day. Under a state law enacted in October 2025, incarcerated firefighters are now paid at least $7.25 per hour while actively fighting fires.
And around the world, Indigenous people have been using fire on the landscape for thousands of years. One such practice comes from the Métis tradition in Western Canada. A Cree-Métis scientist shares with us how this low-intensity “good fire” helps rekindle cultural traditions and cultivate healthier ecosystems.

Wildfire Threats and Resilience

Artificial intelligence or AI’s huge appetite for power is reviving demand for older and dirtier fossil fuel energy. We talk about the massive data centers that power AI, community pushback, and how AI seems to be putting vital climate targets out of reach. 
Also, the Make America Healthy Again or MAHA movement has pinpointed some health concerns backed up by credible research, including concerns about pesticides such as the probable carcinogen glyphosate, the key ingredient in Monsanto’s Roundup. But after agribusiness lobbying the Trump Administration erased pesticides from its MAHA Commission report. 
And Braiding Sweetgrass author Robin Wall Kimmerer is also the author of a 2024 book that continues her explorations of gift economies. She shares insights from The Serviceberry: Abundance and Reciprocity in the Natural World and how gift economies can offer an alternative to overconsumption.

AI Power Demand and the Climate, MAHA, MAGA and a Win for Pesticides, and Robin Wall Kimmerer on The Serviceberry.

Climate activist Bill McKibben, who authored The End of Nature nearly 40 years ago, is back with Here Comes the Sun: A Last Chance for the Climate and a Fresh Chance for Civilization. He joins us for a wide-ranging discussion on the stunning growth of renewable energy from the sun and wind, led in part by China, even as the fossil fuel industry digs in.

Living on Earth’s Explorer-in-Residence, Mark Seth Lender provides a refuge for hungry ducks during hunting season. He also observed something remarkable: these “dabbling” ducks have learned to dive for the seed he offers them.

And as a preview for next week’s Winter Solstice storytelling special, we feature a traditional “Wassail Song” with storyteller Diane Edgecomb.
