SYNTHESIS PAPER The Climate Acceleration Index and Cross-Component Coherence in Ocean Heat Content, Sea Level, Marine Heatwaves, and Atmospheric Moisture Introduction Shrinking Doubling Times and the Transition Toward Instantaneous Growth in the Earth System The Earth system is commonly described through long-term trends in temperature, ocean heat content, sea level, and extreme event frequency. These […]

SYNTHESIS FRAMEWORK Climate Acceleration Index (CAI): A Unified Diagnostic of Earth System Energy Imbalance Across Ocean Heat Content, Sea Level Rise, Marine Heatwaves, and Atmospheric Moisture Abstract We propose a unified diagnostic framework, the Climate Acceleration Index (CAI), that integrates multiple observational indicators of Earth system energy imbalance into a single nonlinear acceleration metric. The […]

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 […]

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)=ddtln⁡H(t)k(t)=\frac{d}{dt}\ln H(t)k(t)=dtd​lnH(t) and defines:Td(t)=ln⁡2k(t).T_d(t)=\frac{\ln 2}{k(t)}.Td​(t)=k(t)ln2​. This transforms ocean heat […]

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 […]

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 […]
