by Daniel Brouse and Sidd Mukherjee The Multiplicative Climate Risk Formula The Multiplicative Climate Risk Formula is a real-estate climate-risk model designed to capture how multiple hazards and vulnerabilities can interact and compound rather than occur independently. The framework incorporates interconnected risks including sea-level rise, storm surge, extreme precipitation, flooding, hydroclimatic whiplash, wildfires, drought, extreme […]

Emerging Coupled Feedback Loops Tip Tipping Points
by Daniel Brouse and Sidd Mukherjee Coupled Climate Feedbacks: How Tipping Points Can Trigger Cascading Earth-System Instability From Tipping Elements to Cascading Feedbacks In 2008, a landmark climate-science paper, “Tipping Elements in the Earth’s Climate System,” brought renewed attention to the possibility that major components of the Earth system could undergo abrupt and potentially irreversible […]
Feedback Examples
by Daniel Brouse and Sidd Mukherjee Examples of complex feedback loop coupling: Two of the most important are the lapse-rate feedback and the ice–albedo feedback. They operate through different physical mechanisms, but they are tightly coupled: Lapse-Rate Feedback → Traps Heat Near the Surface Ice–Albedo Feedback → Converts More Sunlight Into Heat Together, they create […]
Water Vapor, Clouds, and Climate Change: Two Very Different and Connected Feedbacks
by Daniel Brouse Water vapor and clouds are closely related, but they are not the same thing—and they play very different roles in the climate system. Water vapor is Earth’s most abundant and most important natural greenhouse gas. As the climate warms, the atmosphere can hold more water vapor, creating a powerful positive feedback: warming […]
Americans Are Feeling the Heat—But Fewer Believe Climate Change Is Happening
by Daniel Brouse An AP-NORC poll reveals a deeply troubling contradiction in the American public’s understanding of climate change: Americans are increasingly experiencing the effects of extreme heat, yet fewer now believe climate change is actually happening. According to the poll, just 66% of Americans say climate change is happening, down sharply from 73% a […]

Wildfire Catastrophe Bonds Surge as Insurers Transfer Record Climate Risk to Capital Markets
by Sidd Mukherjee and Daniel Brouse A New Era of Climate Risk Finance Wildfire-exposed catastrophe bond issuance has surged to $5.183 billion year-to-date in 2026, rapidly approaching the full-year record of $5.55 billion set in 2025. Driven by escalating wildfire losses, expanding climate risks, and increasingly sophisticated risk models, insurers are turning to global capital […]

Methane: A Rapid Link Between Feedbacks and Tipping Points
by Daniel Brouse Introduction: The Fast-Moving Greenhouse Gas Accelerating Climate Change Methane has become a rapid link between climate feedbacks and tipping points. Methane (CH₄), the primary component of natural gas, is one of the most powerful greenhouse gases driving modern climate change. Although methane remains in the atmosphere for only about a decade—far less […]
Five Animals on the Front Line of Climate-Driven Extinction
by Daniel Brouse Climate change is pushing many species toward extinction, but those at greatest risk share several common traits: highly specialized habitats, narrow temperature tolerances, limited geographic ranges, and dependence on disappearing ice, forests, or other fragile ecosystems. As global temperatures continue to rise, these species have little ability to adapt or relocate. Among […]
Climate Shock to the Food System
by Daniel Brouse How Extreme Heat, Drought, Disease, and Global Supply Disruptions Are Reshaping Agriculture and Raising Food Prices Introduction Climate change is increasingly affecting agriculture through multiple, interconnected pathways. Extreme heat, prolonged drought, erratic rainfall, declining water availability, wildfire, shifting pest and disease pressures, and disruptions to livestock production are converging to create a […]
From Polar Amplification to Planetary Rotation: The Cascading Network of Climate Feedbacks and Tipping Points
by Daniel Brouse This is what is happening right now. And with every reinforcing feedback we activate, we amplify what comes next. Polar amplification → weakened equator-to-pole temperature gradients → reduced thermal contrast → atmospheric circulation changes → accelerated Arctic and Greenland ice melt → ICE–ALBEDO FEEDBACK: ice loss → darker surface → greater solar […]
