Does climate change mean every place on Earth should keep getting hotter? No. This Myth vs. Science article explains weather versus climate, regional variation, cold events, global warming, and what long-term temperature records actually show.

Editorial Note

This article is intended for general educational and scientific-literacy purposes. Climate science is a large and continuously developing field, and individual weather events can involve several interacting causes.

The purpose is not to argue for a particular climate policy. It is to examine a specific scientific misconception: the idea that a warming planet should cause every place on Earth to become hotter all the time.

MYTH: Global Warming Means Everywhere Should Keep Getting Hotter

The claim usually sounds something like this:

“If global warming is real, why is it snowing?”

Or:

“It was colder than normal here this winter, so how can the planet be warming?”

At first, the reasoning may seem intuitive. If Earth is warming, shouldn't every location simply become warmer?

The problem is that this treats Earth like one giant thermostat and confuses local weather with the long-term global climate.

Global warming does not mean every town, state, country, or ocean region becomes hotter every day, every season, or even every year. It refers to a long-term increase in Earth's average temperature across the planet.

SCIENCE: Global Warming Is About a Long-Term Global Average

A global average combines temperature measurements from enormous areas of land and ocean over long periods of time.

It does not require every location to change in exactly the same way.

Think about the average grade in a classroom. If the class average rises from 75 to 80, that does not mean every student gained exactly five points. Some students might improve significantly, others only slightly, and a few might even score lower.

The average can rise while individual results vary.

Earth's temperature behaves similarly. Some regions warm faster than the global average, others warm more slowly, and natural climate variability can temporarily make individual locations warmer or colder than their recent norms.

The scientific question is therefore not, “Was my town warmer today?”

It is, “What does the long-term global record show?”

Weather and Climate Operate on Different Scales

Weather describes relatively short-term atmospheric conditions: today's temperature, this week's storm, tomorrow's rainfall, or a cold front moving through a region.

Climate describes patterns measured over much longer periods.

That distinction matters because one snowstorm cannot determine whether the planet is warming. The same principle works in the opposite direction: one unusually hot afternoon cannot, by itself, establish a long-term global climate trend either.

Climate scientists study patterns across decades and across multiple parts of the Earth system. Temperature records are combined with measurements of ocean heat, glaciers, ice sheets, sea ice, sea level, greenhouse gases, and other indicators.

Climate science depends on accumulated evidence rather than one memorable weather event.

A Warming Planet Can Still Have Winter

Global warming does not eliminate seasons.

Earth still has winter because its axis remains tilted. Cold air masses still form, storm systems still move, and snow can still fall when temperature and moisture conditions allow it.

What a warming climate can change is the probability and intensity of certain conditions over time.

An unusually cold event can therefore occur in a warming world without contradicting the broader trend.

A useful analogy is a loaded pair of dice. Imagine changing the dice so higher numbers become somewhat more likely. You can still roll a two. The appearance of a low number does not prove the probabilities never changed.

Climate change is better understood as shifting distributions and probabilities than as turning up a thermostat that guarantees the same result everywhere.

Regional Variation Is Expected, Not Contradictory

Earth's climate system is geographically uneven.

Land, oceans, ice, vegetation, mountains, clouds, atmospheric circulation, and ocean currents all influence how temperatures change in particular locations.

The Arctic provides one of the clearest examples. It has warmed substantially faster than the global average, a phenomenon known as Arctic amplification. Changes in sea ice, snow cover, water vapor, heat transport, and other processes contribute to that difference.

Oceans behave differently from land as well. Water can absorb and store enormous quantities of heat, and ocean currents redistribute that energy around the planet.

NOAA reported that upper-ocean heat content reached a record high in 2025. That is important because surface air temperature is only one indicator of warming; much of the additional heat in Earth's climate system is stored in the oceans.

Regional differences are therefore part of the science, not evidence against it.

A Colder Region Can Exist During a Very Warm Global Year

The year 2025 provides a useful example.

NOAA ranked 2025 as the third-warmest year in its global record, which begins in 1850. The global surface temperature was 1.17°C above the twentieth-century average. NOAA also reported that the ten warmest years in its historical record had all occurred since 2015.

Yet not every location was warmer than average.

NOAA documented cooler-than-average annual conditions in portions of the tropical central and eastern Pacific and eastern Antarctica. During December 2025, cooler-than-average areas included Alaska, parts of Canada, the northeastern United States, and central Russia.

Those colder regions did not contradict the global result.

They simply demonstrate why a global average should not be expected to look identical in every location.

Natural Climate Variability Still Exists

Human-caused warming has not switched off natural climate variability.

El Niño and La Niña still influence global and regional temperatures and rainfall. Volcanic eruptions can temporarily affect climate. Ocean circulation changes. Atmospheric circulation changes. Storm tracks move.

These processes operate alongside the longer-term warming trend.

That is why one year does not have to be warmer than the year immediately before it.

NASA found that 2025 was cooler globally than record-setting 2024, while still remaining among the warmest years measured. NASA's analysis placed 2025 effectively tied with 2023 within the uncertainty of its methodology.

A long-term upward trend can contain short-term rises and falls.

That is normal statistical behavior.

Climate Change Means More Than Air Temperature

The term climate change is broader than global warming.

Rising global temperature is central to the process, but Earth's climate includes the movement of energy and water throughout the atmosphere, oceans, ice, land, and ecosystems.

A warmer climate can influence rainfall patterns, drought, snow and ice, ocean heat, sea level, wildfire conditions, and some types of extreme weather.

That is another reason the phrase “global warming” can sometimes be misunderstood. People may imagine the scientific claim is simply that every afternoon should become hotter.

The actual science describes changes throughout a complex Earth system.

Those changes do not appear in the same way everywhere.

Does Climate Change Cause Every Heat Wave, Flood, or Storm?

No.

Scientific attribution requires more precision than that.

Heat waves, floods, droughts, wildfires, hurricanes, and other extreme events existed before modern human-caused warming. Climate scientists therefore do not need to claim that climate change single-handedly created every individual event.

Researchers can instead study whether a warmer climate changed an event's likelihood or intensity.

Those are different questions.

For example, scientists might investigate whether a particular type of heat wave became more likely under current climate conditions than it would have been in a cooler world.

That approach is much more scientifically useful than assigning every unusual weather event to one cause.

Cold Events Require the Same Caution

The same standard should apply to unusually cold weather.

Changes in atmospheric circulation, sea ice, ocean conditions, and storm patterns can affect regional weather, but it would also be overly simplistic to claim that every severe cold outbreak was “caused by climate change.”

Regional weather has always varied.

Specific attribution requires evidence about the event and the mechanisms involved.

The scientifically responsible position is therefore more nuanced than either extreme.

A cold snap does not disprove global warming.

But neither should every cold snap automatically be described as a result of global warming.

One Snowstorm Uses the Wrong Scale to Judge Global Climate

Suppose someone stands outside during a snowstorm and says:

“If global warming were real, this snow couldn't exist.”

The biggest problem with the argument is the scale of the evidence.

One location is being used to make a claim about the entire planet. One day is being used to evaluate a trend spanning decades. A local weather event is being compared directly with global climate measurements.

Science requires matching the scale of the evidence to the scale of the claim.

A regional snowstorm tells us something about regional weather conditions.

It does not by itself tell us the direction of Earth's long-term global temperature trend.

The Reverse Mistake Is Wrong Too

Scientific reasoning should work consistently.

A person should not point to one blizzard and claim that global warming has been disproven.

But someone should also avoid pointing to one heat wave and saying that the event by itself proves every conclusion in climate science.

The strongest evidence for modern warming comes from many independent observations that converge on the same broader pattern.

Surface temperatures are one part of that evidence. Ocean heat, glaciers, ice sheets, sea level, greenhouse-gas concentrations, satellite measurements, and other indicators add additional information.

Science is strongest when conclusions rest on multiple lines of evidence rather than anecdotes selected because they support a preferred argument.

What Do Recent Temperature Records Show?

Recent global records continue to show a pronounced warming trend.

NOAA ranked 2025 as the third-warmest year in its record dating to 1850. NASA found 2025 effectively tied with 2023 within its analytical uncertainty, while 2024 remained the hottest year in NASA's record. Copernicus also ranked 2025 third and reported that the eleven years from 2015 through 2025 were the eleven warmest in its dataset.

The exact rankings differ slightly because scientific organizations use different datasets and analytical methods.

That disagreement over small ranking differences is not evidence that scientists are unsure whether long-term warming is occurring.

Independent analyses using somewhat different methods still show the same broad pattern.

Human Activity Is the Main Driver of the Current Warming

Earth's climate has changed naturally many times throughout its history.

That fact is not disputed.

The scientific question is what is causing the current warming trend.

The Intergovernmental Panel on Climate Change concluded in its Sixth Assessment Synthesis Report that human activities, principally greenhouse-gas emissions, have unequivocally caused global warming.

NASA likewise identifies human activities, particularly the burning of fossil fuels and resulting increases in heat-trapping greenhouse gases, as the dominant cause of the modern warming trend.

Natural processes continue to influence individual years and regions, but they do not adequately explain the scale and pattern of the long-term global warming that has been observed.

The Greenhouse Effect Does Not Mean Everything Heats Equally

The greenhouse effect is a physical process in which certain atmospheric gases absorb and re-emit infrared radiation, reducing the rate at which some energy escapes from Earth to space.

The natural greenhouse effect is necessary for life as we know it. Without it, Earth would be much colder.

Increasing concentrations of greenhouse gases add to that heat-trapping effect.

But adding energy to a complex climate system does not mean every location receives exactly the same temperature increase. The additional energy interacts with oceans, ice, clouds, vegetation, land surfaces, atmospheric circulation, and the water cycle.

Complex regional outcomes are therefore expected.

The complexity does not undermine climate science.

It is part of what climate scientists are studying.

VERDICT

MYTH: If global warming is real, every place on Earth should keep getting hotter.

SCIENCE: Global warming describes a long-term increase in Earth's average temperature. Individual locations can still experience snowstorms, cold winters, cooler-than-average periods, and different rates of warming because weather, natural variability, geography, oceans, and atmospheric circulation continue to operate.

VERDICT: A cold day or regional cold spell does not disprove global warming. The relevant evidence is the long-term global pattern, and multiple independent temperature datasets continue to show that Earth is warming.

Why This Myth Is a Useful Science Lesson

This misconception is valuable in the classroom because it demonstrates how easily people can confuse different scales of evidence.

Weather and climate are connected, but they are not identical. Local and global measurements are related, but they answer different questions. Short-term variability and long-term trends can occur simultaneously.

Those principles apply throughout science.

One patient does not define the outcome of an entire medical study. One animal does not define an entire species. One unusual experimental result does not overturn a large body of replicated evidence without further investigation.

Students should learn to look for patterns, mechanisms, uncertainty, replication, and evidence collected at an appropriate scale.

Climate science provides an excellent example of why those habits matter.

New To Education Perspective: Science Education Should Teach Students How to Evaluate Claims

Climate change is frequently discussed alongside politics and public policy, which can make it difficult for students to distinguish different kinds of questions.

Science asks what is happening to Earth's climate, how scientists measure it, what physical mechanisms explain the observations, how confident researchers are, and what uncertainties remain.

Policy asks additional questions about how governments, businesses, communities, and individuals should respond.

Those discussions are related, but they are not identical.

People can disagree over taxation, energy policy, regulation, infrastructure, international agreements, or the proper balance between environmental and economic priorities while still describing the underlying physical science accurately.

That distinction is important for scientific literacy.

Students should be able to hear the claim “It snowed, so global warming cannot be real” and identify why the evidence does not support that conclusion. They should also be able to encounter an exaggerated claim about a particular weather event and ask whether scientists have actually established that connection.

Science education should not merely tell students which side of an argument to repeat.

It should teach them how to examine the evidence behind the claim.

Key Takeaways

Climate change does not mean every location becomes hotter every day, season, or year. Global warming refers to a long-term rise in Earth's average temperature, while weather continues to vary across individual places and shorter periods.

Regional differences are expected. The Arctic has warmed particularly rapidly, while land, oceans, atmospheric circulation, natural climate cycles, and geography create different patterns around the world.

Cold weather does not disprove global warming, just as one heat wave alone does not establish the entire scientific case for climate change. Scientists instead rely on long-term measurements and multiple independent lines of evidence.

Recent global records remain consistent with continued warming. NOAA ranked 2025 as the third-warmest year in its record, NASA found 2025 among the warmest years measured while 2024 remained its record year, and Copernicus reported that 2015 through 2025 were the eleven warmest years in its dataset.

FAQ

If global warming is real, why does it still snow?

Global warming raises long-term average temperatures but does not eliminate winter, cold air masses, moisture, or storm systems. Snow can continue to occur whenever local atmospheric conditions support it.

Does one unusually cold winter disprove climate change?

No. A cold winter represents regional weather and short-term variability. Climate trends are evaluated across much longer periods and larger geographic areas.

Does every part of Earth warm at the same rate?

No. Regional warming varies substantially. The Arctic is one important example of a region that has warmed much faster than the global average.

Was 2025 the hottest year ever recorded?

No. NASA, NOAA, and Copernicus retained 2024 as the warmest year in their respective modern records. NOAA and Copernicus ranked 2025 third, while NASA found 2025 effectively tied with 2023 within its analytical uncertainty.

Can climate scientists separate natural variability from long-term warming?

Scientists use long-term observations, statistical analysis, physical theory, climate models, and multiple independent datasets to study both natural variability and longer-term trends. Natural variation continues to occur while the underlying global climate changes.

Final Thoughts

The idea that global warming should make every location continuously hotter sounds reasonable only if Earth is treated as a simple system.

It is not.

Earth contains oceans, continents, mountains, ice sheets, deserts, forests, atmospheric circulation, ocean currents, seasons, storms, and natural climate cycles. All of those processes continue operating as the planet warms, creating substantial variation from one place and year to another.

That is why a snowstorm does not erase decades of temperature measurements, and a colder-than-average month in one region does not tell us what is happening to the planet as a whole.

The better scientific question is not whether every place was hotter today.

It is what the accumulated evidence shows about Earth's climate over time.

Multiple independent records continue to point toward the same conclusion: Earth is warming, even though that warming does not look identical everywhere.
