The Growing Megafire Crisis — and How to Contain It | George T. Whitesides | TED
Introduction to Santa Rosa Wildfire
This section introduces the story of a wildfire in Santa Rosa, California, and its devastating impact on the community.
The Start of the Disaster
- Joy Durand receives a phone call at midnight on October 8, 2017, urging her to evacuate immediately as fire approaches.
- Joy gathers her family and leaves their home just minutes before it is consumed by the Tubbs Fire.
Unfolding Disaster
- The narrator's wife receives messages throughout the night about the unfolding disaster in Santa Rosa.
- The fire claims 22 lives and destroys over five thousand homes and structures.
The Growing Challenge of Wildfires
This section highlights how wildfires are becoming more common and poses a significant challenge globally.
Increasing Frequency of Wildfires
- Santa Rosa is not an isolated incident; similar disasters have occurred in Paradise (2018), Australia (2020), and Europe (2022).
- Experts predict that wildfire incidents will continue to worsen before improving.
Carbon Impact of Wildfires
- In addition to human and economic costs, wildfires also have a significant carbon impact. California's 2020 wildfires released more carbon than what had been saved over two decades.
Megafires and Overwhelm
This section discusses the increasing severity of megafires and the overwhelming feeling associated with the wildfire crisis.
Escalating Megafires
- Megafires, which burn over 100,000 acres, have become more frequent in California. Eight of the ten largest megafires in California history occurred in the past five years.
Feeling Overwhelmed
- The narrator acknowledges feeling overwhelmed by the wildfire crisis.
Addressing the Megafire Crisis
This section introduces three solutions to address the megafire crisis: fire-adapted communities, resilient landscapes, and innovative fire management.
Solution 1: Fire-Adapted Communities
- Clearing vegetation around homes and using fire-resistant materials can help protect communities from wildfires.
- Protecting homes from flying embers is also crucial.
Solution 2: Resilient Landscapes
- Restoring balance to western landscapes by reducing overgrown brush and trees can mitigate the risk of megafires. Indigenous peoples' practice of controlled burns provides valuable wisdom in this regard.
Challenges and Solutions Ahead
This section highlights the challenges faced in addressing wildfires and proposes solutions for a sustainable future.
Scale of Challenge
- The vast expanse of wildland in American forests presents a significant challenge. The Forest Service aims to reduce risk on 50 million high-priority acres over ten years but faces limitations due to pace and scale.
Solutions Ahead
- To address the challenge, more workers need to be hired, trained, and retained to perform necessary forest management tasks.

New Section
This section discusses the concept of using technology and innovation to address the issue of wildfires. It introduces BurnBot, a company aiming to make controlled burns safer and faster. The importance of scaling up innovative solutions is emphasized.
BurnBot: Making Controlled Burns Safer and Faster
- BurnBot is a company focused on making controlled burns safer and faster.
- Their approach involves establishing a burned perimeter using a remotely piloted rover.
- A drone is then used to drop fire into the interior area, allowing for safe burning.
New Section
This section highlights the need for more innovative solutions to tackle the wildfire problem at scale.
Scaling Up Innovation for Wildfire Management
- Innovation is crucial in addressing and solving the wildfire problem.
- The first two solutions discussed are widely agreed upon, while innovative fire management remains somewhat controversial.
- Scaling up innovative approaches will be necessary to match the magnitude of the challenge.
New Section
This section emphasizes the importance of rapid detection, assessment, and containment of fires through innovation and technology.
Rapid Fire Management: Detecting and Containing Fires
- The key requirement is innovation and technology that can quickly detect, assess, and extinguish fires.
- Speed is paramount during extreme fire days when bringing resources promptly can prevent unmanageable situations.
- The Quick Reaction Force (QRF) in Southern California serves as an example with its public-private partnership utilizing Chinook helicopters capable of precise water drops multiple times per hour.
New Section
This section explores the potential future of distributed networks using larger drone vehicles for fire management in high-risk areas.
Distributed Networks for Fire Management
- The QRF's success demonstrates the potential of bringing a significant amount of fire management resources quickly to control fires before they become unmanageable.
- A future vision involves a distributed network of larger drone vehicles strategically positioned in high-fire-risk areas, such as along utility lines or deep in forests.
- These vehicles, connected to the right sensor system, could enable effective fire suppression even in remote communities.
New Section
This section emphasizes the importance of sensor systems for detecting and differentiating between various types of fires.
Sensor Systems for Fire Detection and Differentiation
- Companies like Rain and Joby Aviation are working on developing sensor systems for fire management.
- Ground-based, aerial, and space-based platforms will be utilized to detect fires promptly.
- The ability to differentiate between low-intensity and high-intensity fires is crucial for effective fire management and rejuvenation of forests.
New Section
This section highlights the broader implications of managing fire for human life, property protection, carbon emissions reduction, and biodiversity preservation.
Managing Fire for a Resilient Future
- Fire serves as a prism through which humanity's relationship with natural systems can be understood.
- By working together and leveraging technology, resilient communities can be built that are capable of withstanding wildfires.
- Managing fire not only protects human life and property but also contributes to global carbon emissions reduction and biodiversity preservation.
- The ultimate goal is to become stewards of Spaceship Earth by learning from fire and building a sustainable future.
