🇨🇺❄️ Cuba reaches the freezing point — a тревожный signal for the world

On February 3, 2026, Cuba recorded its lowest temperature on record: 0.0°C at the Indio Hatuey station — the first confirmed case of the country reaching the freezing point.

🌡️ This is not an isolated anomaly, but a sign that Earth’s climate system is losing balance. Extreme temperature swings are now affecting even tropical regions.

🌍 We are entering a period of abrupt climate change, threatening ecosystems, food security, and daily life.

Millions across the country faced dangerously cold conditions after the storm dumped snow in at least 17 states, disrupting travel and causing power outages.

Millions of people across eastern parts of the U.S. were bracing for dangerously cold temperatures on Monday, as local governments and residents scrambled to restore damaged infrastructure and halted services after a major winter storm.

The storm dumped snow across 17 states, from New Mexico to New Hampshire, according to preliminary figures from the National Weather Service, with more than a foot of accumulation in some areas. More than 85 million people remained under an extreme cold warning early Monday, and forecasters warned that hazardous temperatures would remain for days in some areas.

Transit disruptions are expected to continue in many cities on Monday, as officials advised against travel and reduced schedules for trains and buses. Air travel was also still disrupted, with more than 4,000 cancellations for U.S. flights early Monday, according to the airline tracker FlightAware.
