just to confirm what i have been checking my self thru the years . as per the GSM and Magnetic reversal symptoms we should experience increasing number of thunder strikes. i asked grock to analyze data from

Analyzing global lightning strike data involves synthesizing information from available sources to understand trends in stroke frequency over time. Based on the provided context, particularly the X post from
@Grok, global stroke incidence (in millions) shows an increasing trend from 2005 to 2025. The data points are:
- 2005: 9.5 million strokes
- 2010: 10.2 million strokes
- 2015: 11.0 million strokes
- 2020: 11.6 million strokes
- 2025: 12.2 million strokes (projected)
This suggests a gradual rise in global lightning activity, potentially linked to climatic factors like increasing temperatures or atmospheric instability, though the exact causes are complex and not fully detailed in the sources. Additional context from web sources indicates that global lightning occurs at a rate of about 44±5 strikes per second, totaling approximately 1.4 billion flashes annually, with about 70% occurring in the tropics and more over land than oceans. The 2024 Vaisala Xweather report notes 2.23 billion lightning events detected globally, with significant activity in countries like the United States, Brazil, Australia, the Democratic Republic of the Congo, and Indonesia.
To visualize this trend, I’ll create a line chart showing the global stroke incidence from 2005 to 2025, using the data from the X post, as it provides a clear time series for global stroke counts.

Analysis of the Chart
The chart illustrates a steady increase in global lightning strikes from 9.5 million in 2005 to a projected 12.2 million in 2025. Key observations:
- Trend: The data shows a consistent upward trend, with an average increase of approximately 0.17 million strikes per year over the 20-year period.
- Context: The rise aligns with reports of increased lightning activity in 2024, potentially influenced by 2024 being the hottest year on record. However, the connection between temperature and lightning is complex, as noted in the Vaisala report.
- Geographic Insights: While the chart focuses on global totals, sources indicate that over 50% of lightning occurs in just five countries (USA, Brazil, Australia, DRC, Indonesia), with the tropics dominating due to favorable conditions for thunderstorms.
Limitations
- The data relies on a single source for specific yearly counts, and the 2025 value is a projection, introducing uncertainty.
- Global averages mask regional variations, such as high lightning density in places like Lake Maracaibo, Venezuela, or low activity near the poles.
- Detection efficiency (80–90% for networks like NLDN) and differences in data collection (e.g., ground-based vs. satellite sensors) may affect reported totals.
For a more detailed analysis, historical data from sources like Vaisala’s GLD360 or NASA’s Lightning Imaging Sensor could provide regional breakdowns or flash density per square kilometer. If you’d like a chart focusing on a specific region or metric (e.g., flash density), please let me know
