Staying informed during climate emergencies

Access to accurate, real-time information is critical during disasters. Keep in mind power outages and misinformation can disrupt it.

Keep a battery-operated or hand-crank radio to receive emergency broadcasts even during blackouts. Know which national and local channels provide alerts and write the station numbers on the radio in permanent ink.

If the internet is available, use official sources and trusted scientific platforms. Avoid rumors and unverified social media. Pre-subscribe to SMS or app-based alert systems where available, and help others in your network access information.

Emergency communication strategies

Communication networks may fail or be overwhelmed; plan for backup methods.

Have a printed list of essential contacts and memorize at least one or two key phone numbers. Use agreed-upon meeting points and check-in times with family or friends if phones are down. Walkie-talkies, CB/HAM radios, or mesh network apps can provide local communication without cell towers.

Use message boards or pre-arranged signal systems (e.g. chalk marks, fabric flags) when tech fails entirely.

Digital security & surveillance avoidance

In times of unrest or digital repression, your online activity may be tracked, limited, or used against you.

Use encrypted apps for sensitive communications and enable disappearing messages. Avoid storing sensitive data on cloud platforms. Keep key files on encrypted USB drives or offline paper backups. Use VPNs, disable GPS when not needed, and be cautious about what you share on social media, even in casual posts.

If surveillance intensifies, consider digital hygiene practices such as anonymizing devices, rotating accounts, or going offline entirely.
