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 […]
Climate Change as a Fracture Fractal
In chaos theory, fractal geometry, and fracture mechanics, the pattern you’re describing is usually referred to by several related terms rather than one single universally accepted name: 1. Fracture Fractals The most common scientific term is fracture fractal or fractal crack pattern. These occur when a crack propagates through a material and develops: Examples: 2. […]

Heat Stress, Environmental Stressors, and the Limits of Human Adaptability
A Follow-Up to Heat Stress, Human Survivability, and the Emerging Physiological Limits of Climate Change http://membrane.com/global_warming/Heat-Survivability-Thresholds.html Q: How Adaptable Are Humans to Rising Heat and Compounding Environmental Stressors? A: Far less adaptable than many assume. Modern humans (Homo sapiens) are approximately 200,000 years old, with some of our closest ancestral lineages dating back roughly 140,000 […]

Cracked Windshields and Cracked Fractals
What Climate Science Looks Like What does climate change look like? In many ways, it resembles a cracked windshield. At first, you may not notice anything at all. Time passes. The damage appears minor or even invisible. Then one day, a small fracture catches your eye — just a tiny finger crack stretching across the […]

The Nonlinear Acceleration Framework: Collapsing Doubling Times in Climate Change Impacts
Climate Change Acceleration A real good rule of thumb – climate impacts are accelerating at ~2^6-fold per decade. What does that mean? The Nonlinear Acceleration framework focuses on the rate of acceleration of climate change. At the time the hypothesis was first developed in the 1990s, observed acceleration rates were closer to ~2^1-fold per century […]

Heat Stress, Human Survivability, and the Emerging Physiological Limits of Climate Change
For decades, many researchers assumed humans could generally survive “wet-bulb” temperatures near 35°C (95°F at 100% humidity) for limited periods. This threshold was widely treated as the upper survivability boundary for healthy individuals under shaded and ventilated conditions. Many newer experiments now indicate that: These newer laboratory experiments using controlled climate chambers now suggest that […]

Heat Domes, Climate Instability, and the Growing Need for Household Climate Control
Introduction Heat damages the immune system and even affects genetic and cellular stability. New research suggests the temperature threshold for these harmful impacts may be significantly lower than previously understood. A Corsi–Rosenthal Box can help improve indoor comfort by enhancing air circulation, reducing particulate pollution, and supporting more stable indoor temperatures. As climate change drives […]
Rossby Waves, Climatic Whiplash, and the Nonlinear Destabilization of Atmospheric Circulation
By Daniel Brouse and Sidd Mukherjee May 25, 2026 Abstract Rapid Arctic amplification, accelerating Antarctic ice loss, and weakening ocean circulation are increasingly destabilizing Earth’s atmospheric circulation systems. One of the clearest manifestations of this destabilization is the amplification and persistence of Rossby waves — large-scale meanders in the jet stream that regulate heat transport, […]
