- Forecasting extreme space weather, such as different types of solar activity becomes increasingly important given their potential impact on the operations of critical infrastructures; e.g. solar flares, solar radiation storms or geomagnetic storms could affect radio, radar, ground- and space-based communications, GPS, satellite, aviation, rail transport and power-grid operations. | Related Megatrends: Technology; Security
- Weather-related disasters could affect around 66% of the European population annually by 2100, potentially resulting in a 50-fold increase in fatalities compared to today.
Extremely impoverished people are at most risk from climate change, water scarcity, flooding, limited access to energy and land degradation. This is mainly because they have...
