We saw some of this coming, the flood risk aint justalong the coast, it extends 100 miles inland…the water cant get out …” https://yaleclimateconnections.org/2026/08/the-floods-of-the-future-wont-come-one-at-a-time/ In the 1990s, Sidd and I began developing real-estate-based climate risk models. From the beginning, one of […]

Global Real Estate Climate Risk: A Multiplicative Vulnerability Ranking
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 […]
Coupled Climate Feedbacks and Cascading Real Estate Risk
by Daniel Brouse and Sidd Mukherjee How Compound Flooding Is Reshaping Property Values, Insurance Availability, and Coastal Habitability Climate change is creating a new class of real-estate risk in which the physical hazards of flooding increasingly interact with financial, insurance, infrastructure, and housing systems. Sea-level rise, heavier precipitation, and more intense or slower-moving hurricanes are […]
High-Risk U.S. Real Estate Regions Under the Multiplicative Climate Risk Framework

Climate Change and Flood Insurance
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 same events were being reclassified as 100-year floods. By the 2020s, they increasingly resembled 10-year floods. Today, in some regions, comparable flood events are occurring every few years. The […]
The Climate Discount: Underestimating the Decline in Real Estate Values
Nonlinear Acceleration, Cascading Feedbacks, and the Compression of Climate Time Daniel Brouse¹ and Sidd Mukherjee²March 11, 2026 ¹Independent Climate Researcher, Economist²Physicist Abstract Recent observations across multiple climate indicators confirm that the impacts of global warming are accelerating at a nonlinear rate. We revisit the Nonlinear Acceleration Hypothesis, originally proposed in the early 1990s, which posits […]
Florida at the Front Line: How Accelerating Sea-Level Rise Is Reshaping the State in Real Time
by Daniel Brouse December 5, 2025 Florida faces a long list of climate-driven threats — extreme heat, stronger hurricanes, toxic algal blooms, and collapsing insurance markets — but accelerating sea-level rise (SLR) sits at the center of nearly all of them. Although the current rise of a few millimeters per year may sound trivial, the […]
Climate-Accelerated Flooding in Delaware and Chester Counties: The Brandywine Creek Threat
by Daniel Brouse December 2, 2025 Mapping by the U.S. Geological Survey (USGS) highlights Brandywine Creek, the Christina Basin, and multiple watersheds across Delaware County as major flood-risk zones—an assessment that aligns with the region’s accelerating exposure to extreme weather. The USGS flood inundation maps show that the Brandywine is especially prone to rapid rises […]
Flooding at Coastal Sites That Use and Produce Hazardous Substances
Sea level rise and flooding of hazardous sites in marginalized communities across the United States Published in Nature / 20 November 2025 Sea level rise (SLR) increases the risk of flooding at coastal sites that use and produce hazardous substances. We assess whether socially marginalized populations in the United States are more likely to be […]
Trump’s Socialism Irony: The “Flee to Florida” Fantasy Meets Climate Reality
Donald Trump recently warned that New Yorkers would “flee to Florida” after Zohran Mamdani’s electoral win — a comment loaded with irony so deep it borders on parody. Because here’s the reality: Florida is the first U.S. state to effectively socialize its homeowner’s insurance system. The state government, through taxpayer-backed programs, now functions as the […]
