by Daniel Brouse Absolute humidity—the total amount of water vapor in the air—is increasing globally as the climate warms. The fundamental physics is straightforward: according to the Clausius–Clapeyron relationship, warmer air can hold substantially more water vapor. For every 1°C (1.8°F) of warming, the atmosphere’s water-holding capacity increases by roughly 7%. As human-caused greenhouse gas […]

Real Estate Climate Risk Models
by Daniel Brouse and Sidd Mukherjee Background Sidd said: “frightening article by Jeff Masters. 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 […]

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 […]

Strategic Petroleum Reserve Falls to Lowest Level Since 1983
As of July 31, 2026, the U.S. Strategic Petroleum Reserve (SPR) held approximately 304.8 million barrels of crude oil, its lowest level since March 1983. From its historic peak of roughly 726 million barrels in 2009, the SPR has experienced a cumulative drawdown of approximately 421 million barrels—about a 58% reduction. The decline has been […]
