Heat Storms: A New Way to Define Extreme Heat

Extreme heat events are increasingly described as heat storms when they cover more than 1% of the planet, a threshold used to convey severity and scale. The discussion explains how this definition differs from conventional heat waves and how it allows the size and impact of such events to be quantified. It also points to a Reuters report and a real-time tracking resource for heat storms and heat waves worldwide.

■ Heat storm definition and scale
- Criteria: heat events covering more than 1% of Earth's surface
- Reported events reaching 10%, 20%, or 30% of the planet
- Rationale for using a term beyond "heat wave"

■ Quantification and monitoring
- How the definition supports measuring effects
- Reference to a full Reuters report
- Real-time tracking available on Reuters.com

The material is suited to viewers seeking a concise overview of changing terminology and monitoring approaches for large-scale extreme heat. It provides a framework for understanding the scale of such events and directs those interested to further reporting and tracking tools.
