Former US President Donald Trump posted on his social media platform that a record cold winter storm in the United States proves that global warming is a “hoax.” He asked skeptically, “Whatever happened to global warming?” as heavy snowfall and extreme cold spread across many states.
Trump’s comment caught attention because it challenged the scientific consensus on climate change and questioned whether global warming is real, especially when people experience unusually cold weather.
Why Weather ≠ Climate
Climate scientists quickly pointed out that weather and climate are not the same things.
- Weather refers to short-term conditions like a snowy day or a week of cold temperatures.
- Climate refers to long-term trends over decades or centuries. A cold winter day does not cancel out overall global temperature increases.
Experts emphasize that even in a warming world, extreme weather events — including severe winter storms — can still occur. Some climate research suggests that changes in atmospheric circulation, linked to warming Arctic conditions, can even make winter storms more intense or erratic in certain places.
Scientific Evidence Still Shows Warming Trend
Global data show that average global temperatures are rising, ice sheets are shrinking, glaciers are melting, and weather patterns are becoming more unpredictable. These long-term changes continue to support the overall scientific understanding that the planet is warming due to human-driven climate change.
Scientists have repeatedly warned that ignoring climate science or misinterpreting isolated weather events can delay necessary action, increasing risks from sea-level rise, heat waves, droughts and severe storms.
Why the Misunderstanding Happens
It is a common misconception that cold weather disproves global warming. This happens because people often mix up short-term weather events with long-term climate trends. Observing a cold snap does not provide evidence against global warming — the planet can warm overall while still producing local periods of cold weather.
Conclusion
While extreme weather like a giant winter storm can feel contradictory to the idea of a warming planet, scientists stress that individual cold events do not negate decades of climate data showing rising global temperatures. Misunderstanding this difference can mislead the public and hinder efforts to address climate change effectively.
