DISCOVERY (Results Paper) Abstract We apply a model-independent instantaneous doubling-time framework to global ocean heat content (OHC) from NOAA/NCEI and IAP/CAS datasets spanning 1960–present. Unlike traditional exponential or linear fits, we estimate the local growth rate directly from observational data. Both datasets show that time-varying exponential models significantly outperform linear and stationary exponential models. Residual […]

Instantaneous Doubling Time as a Non-Stationary Diagnostic of Ocean Heat Content Dynamics
METHODS (Framework Paper) Abstract This paper introduces a model-independent diagnostic for assessing temporal changes in ocean heat accumulation: the instantaneous doubling time of ocean heat content (OHC). Rather than fitting parametric exponential or linear growth models, the method estimates the local growth rate directly from observations using:k(t)=ddtlnH(t)k(t)=\frac{d}{dt}\ln H(t)k(t)=dtdlnH(t) and defines:Td(t)=ln2k(t).T_d(t)=\frac{\ln 2}{k(t)}.Td(t)=k(t)ln2. This transforms ocean heat […]
Shrinking Effective Doubling Time in Global Ocean Heat Content
Evidence from Time-Varying Growth Models in NOAA and IAP Observations (1960–Present) Introduction The Earth’s oceans are the planet’s primary heat reservoir, absorbing approximately 90% of the excess heat generated by anthropogenic greenhouse gas emissions. As a result, changes in ocean heat content (OHC) provide one of the most robust indicators of the Earth’s energy imbalance […]
Climate Regime Shift: From a Normal Distribution to a Right-Skewed Distribution
by Daniel Brouse Climate events that were once considered exceptionally rare are occurring with increasing regularity, lasting longer, and causing greater destruction. Introduction One of the most useful tools in science is the normal distribution, better known as the bell curve. It provides a simple way to visualize how observations are distributed around an average […]
July Fourth in Philadelphia: Extreme Heat Puts FIFA Players and Fans at Risk
Philadelphia is forecast to experience a critical heat emergency on July 4, with heat index values expected to reach 91–95°F under dangerously humid conditions. Even modest physical exertion outdoors can increase the risk of heat exhaustion, heat stroke, and, in severe cases, death. Extreme heat is more than uncomfortable—it is one of the deadliest weather […]
The Great Atlantic Sargassum Belt: Climate Change and the Rise of a Record-Breaking Ocean Regime Shift
by Daniel Brouse What many beachgoers describe as a “bad seaweed year” is actually evidence of a much larger transformation occurring across the Atlantic Ocean. Florida is experiencing another massive influx of Sargassum, and scientists monitoring the phenomenon report that the Great Atlantic Sargassum Belt remains near record size. Rather than an isolated event, this […]
Ring of Fire Thunderstorm Feedbacks
Introduction In meteorology, a Ring of Fire describes a recurring pattern in which clusters of powerful thunderstorms repeatedly develop and travel around the outer edge of a large, stationary high-pressure system. These storms form where extremely hot, dry air beneath the heat dome collides with cooler, moisture-rich air circulating around its perimeter. The pattern becomes […]
Heat Can Kill You. Heat Will Age You.
Exposure to extreme heat accelerates biological aging, damaging tissues and shortening telomeres at a cellular level. Although this article focuses on the current heatwave affecting Philadelphia, the same principles apply across much of the world. As climate change drives more frequent and intense heatwaves, millions of people are facing increasing exposure to dangerous combinations of […]
New Data Center Designs and the Evolving Environmental Footprint of AI Infrastructure
by Daniel Brouse New data center designs are dramatically reducing—or in some cases eliminating—direct freshwater consumption by replacing traditional, water-intensive cooling towers with advanced thermal management technologies. Major technology companies and hardware manufacturers are rapidly deploying infrastructure designed to minimize strain on local water supplies while supporting rapidly growing computational demand. One of the most […]
Climate Responsibility and Accountability
Addendum to: Solutions to the Fossil Fuel Economy and the Myths Accelerating Climate and Economic Collapse http://membrane.com/global_warming/Basic-Economics.html Climate Responsibility and Accountability Introduction The original purpose of Solutions to the Fossil Fuel Economy and the Myths Accelerating Climate and Economic Collapse was to focus on practical solutions rather than assigning blame. Since its publication, however, many […]
