The year 2024 may bring a major challenge for our civilization: a massive solar storm that could knock out the power grid for months. This is not a science fiction scenario, but a realistic possibility based on scientific evidence and historical precedents.
A solar storm, also known as a coronal mass ejection (CME), is a huge burst of plasma and magnetic fields from the sun that travels through space at speeds of up to several million miles per hour. When a CME hits the Earth’s magnetosphere, it can cause geomagnetic disturbances that affect the electric currents in the atmosphere and on the ground.
A severe solar storm can damage or destroy satellites, communication systems, navigation systems, and power grids. The most famous example of such an event is the Carrington Event of 1859, which caused widespread telegraph failures and auroras visible as far as the Caribbean. A similar event today would have much more devastating consequences, as our society relies heavily on electricity and technology.

According to a 2008 report by the National Academy of Sciences, a severe solar storm could cause up to $2 trillion in damages and take up to 10 years to recover from. The report estimated that about 130 million people in the US alone could lose power for months or years. The economic and social impacts would be enormous, affecting everything from food production and distribution to health care, education, transportation, and security.
How likely is a severe solar storm in 2024?
The sun goes through cycles of activity that last about 11 years. During the peak of each cycle, known as the solar maximum, the sun produces more sunspots, flares, and CMEs. The next solar maximum is expected to occur around 2024-2025, which means that the risk of a severe solar storm is higher during that period.
However, predicting the exact timing and intensity of a solar storm is very difficult, as there are many factors involved. Some scientists have suggested that the next solar cycle could be weaker than average, while others have warned that it could be stronger than expected. There is also a possibility that a rogue CME could occur at any time, regardless of the solar cycle. Therefore, it is important to be prepared for any scenario, as the consequences of being unprepared could be catastrophic.
How to prepare for a solar storm?
There are several steps that businesses and individuals can take to reduce the impact of a solar storm and increase their resilience. Here are some of them:
Have a backup power source: A generator, solar panels, batteries, or other alternative energy sources can provide electricity in case of a grid failure. Make sure to have enough fuel or storage capacity to last for several weeks or months.
Have an emergency kit: A basic emergency kit should include water, food, medicine, flashlight, radio, first aid kit, and other essential items. Store enough supplies for at least two weeks per person.
Have a communication plan: A landline phone, ham radio, satellite phone, or other communication devices can help you stay in touch with your family, friends, and colleagues in case of a network outage. Have a list of emergency contacts and backup options.
Protect your electronics: A surge protector, a Faraday cage, or other shielding devices can protect your electronics from damage caused by electromagnetic pulses (EMP). Unplug your devices when not in use and store them in a safe place.
Have a contingency plan: A contingency plan should outline how you will cope with various scenarios such as loss of power, water, communication, transportation, or income. Identify your priorities, risks, resources, and alternatives. Review and update your plan regularly.
Stay informed: Monitor the space weather forecasts and alerts from reliable sources such as NOAA’s Space Weather Prediction Center (SWPC) or NASA’s Solar Dynamics Observatory (SDO). Follow the instructions from local authorities in case of an emergency.
A massive solar storm in 2024 may be inevitable, but it does not have to be disastrous. By taking proactive measures to prepare for it, you can minimize its impact on your life and business and increase your chances of survival and recovery.
