Have you ever wondered why we sometimes hear about “global warming” and other times about “climate change”? For many people, the two terms seem synonymous, used interchangeably in news, documentaries, and everyday conversations. But this confusion has a real cost: when we don’t understand exactly what’s happening to our planet, it becomes harder to act effectively to protect it.
The distinction between global warming and climate change is not just a matter of scientific vocabulary. It changes how we see the problem, the solutions we prioritize, and even how we communicate with others about the topic. In 2026, as climate effects become increasingly evident in Brazil and worldwide, understanding this difference is more urgent than ever.
In this article, we’ll explain clearly and accessibly what each term means, where they come from, how they relate to each other, and—most importantly—what you can do with this knowledge. Because understanding the problem is the first step to becoming part of the solution.
Global Warming: What Exactly Is This Phenomenon?
Global warming refers specifically to the increase in the average temperature of Earth’s surface over time, primarily due to human-caused greenhouse gas (GHG) emissions. These gases—including carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O)—form a kind of “blanket” around the Earth, trapping heat that would normally be released into space.
The phenomenon itself is not new nor entirely negative: without the natural greenhouse effect, the planet’s average temperature would be about 33°C colder, making life as we know it impossible. The problem lies in the artificial intensification of this effect since the Industrial Revolution, driven by burning fossil fuels, deforestation, and agricultural and industrial practices.
According to reports from the Intergovernmental Panel on Climate Change (IPCC), the global average temperature has already increased approximately 1.1 to 1.2°C compared to pre-industrial levels. The Paris Agreement, signed in 2015, set a goal of limiting this warming to a maximum of 1.5°C—a limit that experts consider critical to prevent the most severe effects.
Climate Change: A Broader and More Complex Concept
If global warming is a cause, climate change is the set of consequences. The term encompasses all alterations in Earth’s climate patterns—not just temperature increases, but also:
- Changes in rainfall and drought patterns
- Increased frequency and intensity of extreme weather events (hurricanes, floods, heat waves)
- Rising sea levels due to melting glaciers and thermal expansion of oceans
- Alterations in ecosystems, such as coral bleaching and species displacement
- Impacts on agriculture, public health, and water security
The World Meteorological Organization (WMO) and the IPCC prefer the term “climate change” because it’s more comprehensive and technically accurate. It recognizes that warming is just one facet of a profound and multidimensional transformation affecting all of the planet’s natural and human systems.
It’s worth noting that climate changes have always occurred throughout Earth’s geological history—from natural causes such as variations in Earth’s orbit, volcanic activity, and solar variations. What differentiates the current moment is the speed and scale of these changes, driven by human action.
Why Do Both Terms Coexist? The History Behind the Words
The term “global warming” gained popularity in the 1980s and 1990s, especially after scientist James Hansen’s testimony to the U.S. Congress in 1988, which drew public attention to the problem of rising temperatures. It was simple, direct language, easy to communicate.
Over time, however, scientists and communicators realized that the term created some distortions:
- People in regions experiencing harsher winters argued that “if it’s getting warmer, why is it colder here?”
- The exclusive focus on temperature ignored other equally serious impacts
- The term could suggest that the phenomenon was only gradual and slow, when in reality it includes abrupt and extreme events
For this reason, the expression “climate change” became preferred by the scientific community. In Brazil, the Ministry of Environment and Climate Change officially adopts this term in its policies and communications.
Today, both terms are valid and complementary: global warming describes the central mechanism, while climate change describes the full spectrum of transformations it triggers.
How These Phenomena Affect Brazil in Concrete Ways
Brazil is one of the most vulnerable countries—and also one of the most important—in this global climate equation. With the world’s largest tropical forest and unparalleled biodiversity, Brazilian territory functions as a climate regulator on a continental and global scale.
Some impacts already observed and documented in the country include:
- Amazon and Cerrado: Scientific studies indicate that parts of the Amazon are already emitting more carbon than they absorb, especially in heavily deforested regions. The Cerrado, one of the world’s most threatened biomes according to the IUCN, faces increasing pressure from droughts and changes in water patterns.
- Extreme rainfall in the Southeast and South: Events such as the historic floods in Rio Grande do Sul in 2024 show that Brazil already lives with intensified climate extremes.
- Drought and food security: Embrapa has been monitoring how climate changes affect agricultural productivity in different regions of the country, with impacts especially severe in the Northeast.
- Rising temperatures in cities: The urban heat island phenomenon is amplified by global warming, directly affecting the quality of life and health of urban populations.
The Difference That Makes a Difference: Why Understanding This Matters for You
Understanding the distinction between global warming and climate change has very concrete practical implications. See why:
More Effective Communication About Climate
When you talk with friends, family, or colleagues about the topic, using the correct terms avoids common misunderstandings—like the idea that a cold day “proves global warming doesn’t exist.” Climate change includes extremes in both directions.
More Informed Decision-Making
Understanding that climate change affects not just temperature but also the water we drink, the food we eat, and the air we breathe broadens our perception of risk and urgency. This motivates us to act in more varied and effective ways.
Support for Appropriate Public Policies
A well-informed population demands and supports more comprehensive policies—not only focused on reducing emissions (mitigation), but also on adapting territories, cities, and communities to changes already underway.
What You Can Do: Practical Actions Starting Today
The good news is that there are many concrete ways to contribute to addressing both global warming and its broader effects. Here are some practical attitudes, organized by area of impact:
Reduce your direct emissions:
- Prefer public transportation, bicycles, or walking whenever possible
- Reduce red meat consumption, which has a high carbon footprint
- Consume energy from renewable sources—ANEEL provides information on how to switch to solar energy or adopt green tariffs
Consume more consciously:
- Reuse packaging and materials before disposing of them—see some creative ideas for reusing packaging that also help save money
- Reduce food waste by planning your shopping and meals better
- Transform organic waste into fertilizer, as explained in this guide on homemade organic fertilizer
Engage socially:
- Talk about climate change with your network of contacts, using the correct terms and concepts
- Support local conservation organizations and initiatives
- Vote and hold political representatives accountable for concrete climate policy actions
Adapt and help your community adapt:
- Inform yourself about the specific climate risks in your region (floods, droughts, heat waves)
- Plant trees and encourage urban afforestation
- Support urban agriculture initiatives and local food production

Conclusion: Knowledge Is the First Step for Change
Global warming and climate change are not rivals or perfect synonyms—they are parts of the same story humanity is writing in real time. Warming is the trigger; climate change is the set of transformations it triggers in cascade across the planet.
By understanding this difference, you become a more effective communicator, a more conscious consumer, and a citizen better prepared to contribute with real solutions. In 2026, as climate effects become increasingly present in news and daily Brazilian life, this knowledge is not just academic—it’s essential.
The climate crisis is large, but individual and collective actions matter. Each well-informed conversation, each conscious consumption choice, each vote for serious climate policies is a real contribution. Share this article with people you know, start a conversation, plant a seed—of knowledge and, why not, literally as well.
The planet thanks you. And future generations, even more.
