Why freezing temperatures and massive snowstorms don’t disprove global warming — they confirm it.
Every winter, the same doubts make their rounds:
“If the planet’s getting warmer, why is it snowing so much?”
“How can climate change be real when I just shoveled two feet of snow off my driveway?”
At first glance, it seems like a fair question. But in reality, this thinking confuses weather with climate — and overlooks how climate change is reshaping all seasons, not just summer.
Let’s clear the fog. Here are five of the most common myths about climate change and cold weather — and the truth behind them.
1. “If it’s cold outside, global warming must be fake.”
Truth: A cold day doesn’t cancel decades of climate data.
This is the single most widespread misunderstanding. Weather is what you feel right now — a snowstorm, a cold snap, a chilly morning. Climate is the long-term pattern of temperatures and weather extremes over years and decades.
So yes, we’ll still have cold days. Even cold winters. But zoom out, and the trend is clear:
The planet is warming.
In fact, the 10 hottest years ever recorded have all occurred since 2010. And yes — they included snowstorms, blizzards, and frost advisories. Climate change doesn’t make winter vanish. It makes everything more unpredictable.
2. “Snowfall is decreasing because of warming.”
Truth: Not always. In many places, snowfall is actually increasing — but for surprising reasons.
Here’s the twist: warmer air holds more moisture. So when temperatures hover just below freezing, that extra moisture can fall as heavier, wetter snow.
In other words, as long as it’s still cold enough to snow, global warming can fuel more intense snowstorms — not fewer. That’s why we’re seeing events like:
- “Snowmageddon” blizzards in the U.S. Northeast
- Record snowfalls in parts of Canada, Japan, and northern Europe
- Arctic lake-effect snow events driven by warming water and air interactions
Some areas may eventually lose snowfall altogether — but many regions are facing stronger winter storms in the meantime, precisely because the climate is warming.
3. “The polar vortex has nothing to do with climate change.”
Truth: The polar vortex is being directly affected by Arctic warming — and that’s sending cold air your way.
The polar vortex is a fast-moving band of winds that circles the Arctic, keeping cold air locked up near the pole. But climate change is throwing that system off balance.
As the Arctic warms (at more than 4x the global average), it weakens the temperature contrast between the equator and the poles. This disrupts the jet stream and causes the polar vortex to weaken, wobble, and split — letting frigid Arctic air escape into places like:
- The U.S. Midwest and South
- Central Europe
- Parts of East Asia
The result? Sudden, extreme cold spells in places unprepared for them — like the Texas deep freeze of 2021, or winter storms reaching as far south as northern Mexico.
Far from disproving climate change, polar vortex breakdowns are one of its strongest signals.
4. “Climate change means it’ll just get hotter.”
Truth: Climate change means more extremes — including colder events.
It’s a mistake to think of climate change as just “global warming.” What we’re seeing is climate destabilization — which includes:
- More heatwaves
- Stronger storms
- Heavier rainfall
- Longer droughts
- And yes — deeper cold snaps and snow events
This is because the entire climate system is interconnected. A warmer planet means more energy in the atmosphere — and that energy plays out in more intense, less predictable weather of all kinds.
So while the average temperature is rising, the experience of that warming is nonlinear and chaotic — especially in winter.
5. “Only summer weather shows climate change.”
Truth: Winter is changing too — just in ways we don’t always notice right away.
Climate change is affecting every season, including winter. Here’s how:
- Delayed ice formation on lakes and seas — which feeds back into storm formation
- Shorter snow seasons, with abrupt transitions between snow and rain
- Increased freeze-thaw cycles, which can damage roads, crops, and infrastructure
- Warmer Arctic winters, which ironically send cold air south (via the disrupted polar vortex)
Winter storms aren’t disappearing — they’re evolving. And many places are already dealing with new winter weather they’re not prepared for.
Cold Doesn’t Cancel Climate Change — It Proves It’s Working Differently
Global warming doesn’t mean we’ll never feel cold again. It means our weather — including winter — is becoming more extreme, less stable, and harder to predict.
Snowstorms, deep freezes, and icy wind chills don’t contradict climate science — they’re part of the new climate reality.
The sooner we stop mistaking snowflakes for science, the better equipped we’ll be to face what’s coming — and protect the people most vulnerable to it.
