Tropospheric ozone is one of the most dangerous yet least understood environmental threats facing modern society. Invisible to the eye, it functions simultaneously as an air pollutant, a greenhouse gas, and a climate feedback amplifier. Ozone exposure is associated with millions of illnesses and premature deaths worldwide, while also damaging crops, forests, and other ecosystems […]

The Ozone Feedback Theory: Tropospheric Ozone as a Driver of Ecosystem Decline, Carbon Sink Failure, and Climate Acceleration
Abstract Tropospheric ozone is a major air pollutant, a significant short-lived climate forcer, and an increasingly recognized driver of ecosystem decline. While carbon dioxide (CO₂) remains the dominant anthropogenic greenhouse gas, growing evidence demonstrates that ozone plays a critical role in accelerating climate disruption through its impacts on vegetation, carbon cycling, wildfire activity, atmospheric chemistry, […]

Singularity: Turn Down Your Guitar!
This paper is focused on the definitions of three key concepts: runaway climate change feedbacks, Hothouse Earth, Venus Syndrome, and singularity. Understanding the distinctions between these terms is essential because they describe different stages and mechanisms of large-scale system change. I think part of the confusion stems from the distinction between runaway climate change feedbacks and the Hothouse Earth framework. A key […]

Feedbacks and Runaway
Hansen’s recent analyses provide evidence consistent with accelerating climate change and increasing climate sensitivity, findings that align with several aspects of our nonlinear acceleration framework. While interpretations differ regarding magnitude and future trajectories, the growing body of observational evidence suggests that multiple climate indicators are exhibiting nonlinear behavior and interacting feedbacks.

Amazon Rainforest Dieback: Emerging Risks, Feedback Loops, and Scenario-Based Projections
by Daniel Brouse and Sidd Mukherjee June 3, 2026 Framing the Question The Amazon rainforest is widely recognized as one of Earth’s most important climate-regulating ecosystems. It functions as a major carbon sink, stores vast quantities of carbon in vegetation and soils, recycles moisture across South America, and supports extraordinary biodiversity. A growing body of […]
Rainforest Dieback Risk
Reduced Moisture Recycling and Lowered Tipping Thresholds Increase Amazon Rainforest Dieback Risk Under Combined Deforestation and Climate Warming Abstract Recent research synthesis indicates that the stability of the Amazon rainforest is increasingly threatened by the interaction of global warming and regional land-use change. Deforestation is reducing evapotranspiration-driven moisture recycling, weakening regional precipitation patterns and extending […]
Is Climate Change on a Runaway Train?
by Daniel Brouse and Sidd Mukherjee A Public-Access Discussion of Nonlinear Climate Risk Abstract Climate change is often discussed in terms of gradual warming. However, growing evidence suggests that many climate impacts may be accelerating through interacting feedback loops and nonlinear system behavior. This raises an important question: Is climate change entering a runaway state? […]

Climate Change Experiment
Author’s Note What do we think? I am an economist whose work has focused on climate risk management, complex systems, and nonlinear acceleration. My research partner, Sidd Mukherjee, is a physicist. While my background centers on economics, risk, and system dynamics, Sidd’s work extends into areas such as ultra-low-temperature physics, where measurements can approach within […]
Is Climate Change a Runaway Train?
Q: Runaway? Are you suggesting that’s possible or likely? A: It depends on how you define “runaway.”The term “runaway” is often interpreted in a very binary or absolute way, when in reality what we are dealing with may be a spectrum of increasing nonlinear behavior and interacting feedbacks.A core challenge is that we don’t yet […]
The Compression of Time: Where Are We in Climate Change?
The Compression of Time: Where Are We in Climate Change?You Are Here. One of the simplest ways to understand climate change is through the changing frequency of extreme events. In the 1990s, what was considered a 500-year flood was expected to occur, on average, once every five centuries. By the early 2000s, many of those […]
