Climate change is often framed around a simple comparison: How much colder were ice ages than the climate before the Industrial Revolution? While historical temperature comparisons remain scientifically important, they no longer capture the most significant feature of modern climate change. The more important question today is: Has Earth ever experienced a climate transition with […]

Beyond Degrees: Why the Rate of Climate Change Matters More Than Historical Temperature Comparisons
by Daniel Brouse Introduction Climate change is often framed around a simple question: How much warmer is the planet compared with the past? While global temperature remains an important indicator, it does not fully capture the defining characteristic of the modern climate system. The more fundamental shift is not only the magnitude of warming, but […]
Beyond Temperature: How Climate Science Shifted from Measuring Warming to Tracking Earth’s Energy System
Introduction 2023 was a record year for global average surface temperature according to the major observational datasets. However, climate science moved beyond focusing primarily on annual temperature records years ago because, by itself, average surface temperature provides only a limited view of the state of the climate system. Temperature is an important indicator, but it […]

Scientists Should Lead the AI Communication Revolution
By Daniel Brouse Over the past several years, we’ve trained our AI agents on our own climate research to explore new ways of communicating complex scientific concepts. As a result, some of our content reflects the depth of graduate-level research while presenting it in a more accessible visual format. We’ve intentionally experimented with different styles […]
No Sudden Extinction Jump: But a Strongly Constrained High-End Warming Envelope
by Daniel Brouse and Sidd Mukherjee Climate Change Scenarios 101 Q: Is climate change extreme and alarming?A: Yes. Q: Is a single abrupt climate shift likely to trigger immediate human extinction or a sudden global “die-off”?A: No. But the system behavior is still highly nonlinear and increasingly constrained by physical limits. 1) Near-term physical upper […]

Climate Change Health Impact Directory
Climate Change and Human Health A Directory of Research Papers on the Health Impacts of Human-Caused Climate Change Human-caused climate change is no longer simply an environmental issue—it has become one of the defining public health challenges of the twenty-first century. In addition to the direct deaths caused by heatwaves, floods, hurricanes, droughts, wildfires, and […]

Climate Change, Gut Dysbiosis, and the Human Microbiome
How Environmental Stressors Disrupt Gut Health, Sleep, and Systemic Well-Being By Daniel Brouse The human gut microbiome is one of the body’s most complex and essential ecosystems, influencing digestion, immunity, metabolism, and even brain function. A growing body of scientific evidence indicates that climate change is emerging as a significant environmental threat to this internal […]

Climate Change and REM Sleep: How a Warming Planet is Disrupting the Brain’s Most Restorative Sleep Stage
by Daniel Brouse Preface This summer, I began noticing a significant decline in both my overall sleep quality and, in particular, my REM (Rapid Eye Movement) sleep. After reviewing the data from my sleep tracker, I was able to link much of the disruption to elevated nighttime temperatures. Then, last night, another factor became impossible […]

Human-Caused Climate Change and Heatwave Trends
WARNING: Heat can kill you and will reduce your health and wellbeing, whether you believe it or not. Please read the facts. The state of the climate is not normal. Human-Caused Climate Change and Heatwave Trends Human-caused climate change has fundamentally altered global weather patterns, making heatwaves more frequent, more intense, and longer-lasting. According to […]

The Evolving Probability Distribution of Climate Extremes: Earth’s Energy Imbalance, Statistical Skewness, and Feedback Coupling in an Increasingly Energetic Climate System
Daniel Brouse and Sidd Mukherjee July 4, 2026 Abstract Global warming is often communicated through changes in average surface air temperature. While useful, this framing understates the fundamental driver of climate change: the accumulation and redistribution of excess thermal energy throughout the Earth system. Because more than 90% of anthropogenic excess heat is stored in […]
