Could Solar Storms Destroy Civilization? Solar Flares & Coronal Mass Ejections
Kurzgesagt – In a Nutshell・7 minutes read
The Sun can emit dangerous solar flares and coronal mass ejections that affect Earth, with a 12% chance of significant storms each decade, potentially causing widespread damage to electronic systems but not harm to humans due to the atmosphere's protection. Engineers can mitigate these effects by taking transformers offline and investing in grid protection measures to manage the impacts of solar storms on our electricity-dependent civilization.
Insights
- Solar storms, such as solar flares and coronal mass ejections, have the potential to disrupt satellites, radio communication, and power grids, highlighting the vulnerability of modern technology to space weather phenomena.
- The occurrence of severe solar storms, though rare, poses a significant threat to our electricity-dependent civilization, emphasizing the importance of proactive measures like grid protection and preparedness to mitigate potential catastrophic consequences.

What are solar flares and CMEs?
Solar flares are bursts of energy from the Sun, while coronal mass ejections (CMEs) are massive expulsions of plasma and magnetic field from the Sun's corona.
How do solar storms affect Earth?
Solar storms, such as solar flares and coronal mass ejections, can impact Earth by affecting satellites, disrupting radio communication, and potentially harming astronauts in space.
Can solar storms harm people on Earth?
Solar storms, like solar flares and coronal mass ejections, generally do not harm people on Earth due to the protective atmosphere.
How can engineers mitigate the effects of solar storms?
Engineers can mitigate the effects of solar storms by taking transformers and substations offline, opening extra power lines, and investing in grid protection measures.
What is the likelihood of a significant solar storm hitting Earth?
The likelihood of a significant solar storm hitting Earth is estimated at 12% per decade, with potential catastrophic consequences for our electricity-dependent civilization.

Managing Solar Storm Impacts on Earth's Grid
- The Sun, a seemingly peaceful celestial body, can emit dangerous solar flares and coronal mass ejections (CMEs) that can impact Earth.
- The Sun's plasma, composed of electrically charged protons and electrons, creates a magnetic field that shapes the flow of particles, leading to solar storms.
- Solar storms, like solar flares and coronal mass ejections, can affect satellites, radio communication, and astronauts, but generally do not harm people on Earth due to the atmosphere's protection.
- A severe solar storm, like the Carrington Event in 1859, can induce currents in power grids, potentially causing widespread damage to electronic systems.
- Engineers can mitigate the effects of solar storms by taking transformers and substations offline, opening extra power lines, and investing in grid protection measures.
- The likelihood of a significant solar storm hitting Earth is estimated at 12% per decade, with potential catastrophic consequences for our electricity-dependent civilization.
- While solar storms are not preventable, their impacts can be managed through preparedness, observation, and protective measures for the world's electric grid.
