Best Examples of Cause and Effect Essay Examples on Climate Change

Strong Examples of Cause and Effect Essay Topics on Climate Change

When teachers ask for examples of cause and effect essay examples on climate change, they’re really asking for two things: a clear cause (or set of causes) and a measurable effect you can support with data.

Here are several topic directions that work very well in 2024–2025 classrooms and assignments:

• How burning fossil fuels leads to rising global temperatures and more intense heat waves.
• How deforestation in the Amazon and other regions affects rainfall patterns and biodiversity.
• How climate change is driving stronger hurricanes and heavier rainfall in the United States.
• How melting Arctic ice influences sea level rise and coastal flooding.
• How climate change affects human health, from heat-related illness to asthma.
• How individual lifestyle choices (diet, transportation, energy use) contribute to greenhouse gas emissions.

Each of these can be developed into a full essay. Below, we’ll walk through several detailed examples of cause and effect essay examples on climate change, with sample thesis ideas, paragraph structures, and real data you can cite.

Example of a Cause and Effect Essay on Rising Temperatures and Heat Waves

One of the best examples of cause and effect essay topics on climate change focuses on heat waves. It’s specific, timely, and backed by strong data.

Sample thesis
Human-caused greenhouse gas emissions are raising global temperatures, which in turn are increasing the frequency, duration, and intensity of heat waves, especially in cities.

How to build the cause section
You might start by explaining how burning coal, oil, and natural gas releases carbon dioxide and other greenhouse gases. These gases trap heat in the atmosphere. According to NASA and NOAA, the last decade has been the warmest on record, and 2023 ranked among the hottest years documented so far.

To strengthen this example of a cause and effect essay, you could:

• Explain that global average temperature has risen about 2°F (1.1°C) since the late 1800s.
• Mention that this rise is linked strongly to human activities, not natural cycles.

How to build the effect section
Then, move to the effects: more intense and frequent heat waves.

You can show that:

• Many U.S. cities have seen more days above 90°F in recent decades.
• Urban areas experience the urban heat island effect, where concrete and asphalt hold heat longer than green spaces.

The U.S. Environmental Protection Agency (EPA) has climate indicators showing an increase in heat waves in large American cities since the 1960s. Citing this turns your essay from opinion into evidence-based writing.

In this example of cause and effect structure, your body paragraphs might flow like this:

• Paragraph on greenhouse gas emissions and how they trap heat.
• Paragraph on rising global temperatures with data.
• Paragraph on how those higher temperatures translate into more heat waves.
• Paragraph on human impacts: heat stroke, higher energy bills, and stress on power grids.

Examples of Cause and Effect Essay Examples on Climate Change and Extreme Weather

Another powerful angle is to use real examples of climate-linked extreme weather. Teachers love this because it pushes you to connect science with events people actually remember.

Sample thesis
Warming oceans and atmosphere, driven by human activities, are intensifying storms and heavy rainfall events, leading to more destructive flooding and storm damage.

Causes to highlight
You might explain:

• Warmer air holds more moisture, so when it rains, it can pour harder.
• Warmer oceans can feed stronger storms, including hurricanes.

The National Oceanic and Atmospheric Administration (NOAA) provides clear explanations and updated data on how climate change influences storms and precipitation.

Effects to describe
Here is where you bring in real examples of cause and effect essay examples on climate change:

• Heavier downpours in the Midwest and Northeast United States have increased flooding risk for farms and towns.
• Hurricanes like Harvey (2017) and Ida (2021) dropped enormous amounts of rain, partly because a warmer atmosphere held more moisture.
• In 2022 and 2023, several regions around the world saw record rainfall and flash floods that scientists linked to a warming climate.

You can organize your essay with:

• One or two paragraphs laying out the science of warmer air and oceans.
• Several paragraphs each focusing on a different storm or flood as a case study.
• A final paragraph explaining social impacts: damaged homes, displaced families, and rising insurance costs.

This kind of essay shows that examples include not just the science, but also the human stories behind the data.

Deforestation and Changing Rainfall: A Focused Example of Cause and Effect

If you want a slightly different angle, use forests. This is one of the best examples of cause and effect essay examples on climate change because the link between trees and climate is easy to visualize.

Sample thesis
Large-scale deforestation, especially in tropical regions, increases carbon emissions and disrupts local rainfall patterns, which then contributes to both global warming and regional droughts.

Cause section ideas
In your essay, you could explain that:

• Trees absorb carbon dioxide from the air and store it.
• When forests are cut or burned, that stored carbon is released back into the atmosphere.
• Tropical forests, like the Amazon, also recycle moisture back into the air, helping to maintain stable rainfall patterns.

The United Nations climate resources and academic sites such as Harvard University have accessible explanations of how forests interact with climate.

Effect section ideas
Then, show the effects:

• Increased carbon dioxide levels speed up global warming.
• Loss of forest cover can lead to less rainfall in the region, increasing the risk of drought.
• Droughts can hurt agriculture, reduce water supplies, and increase wildfire risk.

In this example of a cause and effect essay, your body might:

• Start with a paragraph painting a picture of a specific forest region.
• Move into how deforestation happens (logging, cattle ranching, agriculture).
• Then explain the chain of effects: more carbon in the air, less moisture cycling, drier conditions.
• Finish with how this affects local communities and global climate goals.

Climate Change and Human Health: Real Examples You Can Use

If you want to connect climate change directly to people’s bodies and daily lives, writing about health is a smart move. It’s also one of the clearest examples of cause and effect essay examples on climate change for students in biology, nursing, or public health.

Sample thesis
Rising temperatures and changing weather patterns are worsening air quality, spreading disease-carrying insects, and increasing heat-related illnesses, especially among vulnerable populations.

Causes to explain
You can cover:

• Higher temperatures and more frequent heat waves.
• Longer warm seasons that allow mosquitoes and ticks to live in new areas.
• More wildfires that send smoke and fine particles into the air.

The Centers for Disease Control and Prevention (CDC) provides detailed information on how climate change affects health in the United States.

Effects to highlight
Here is where your real examples come in:

• Heat waves leading to more emergency room visits for heat stroke and dehydration.
• Worse air quality on hot, stagnant days, which can trigger asthma attacks, especially in children.
• Expanding ranges of ticks that carry Lyme disease into areas that used to be too cold.
• Wildfire smoke traveling hundreds of miles, increasing respiratory problems far from the fire.

In this example of cause and effect essay organization, you might:

• Devote one paragraph to heat-related illness.
• Another to air quality and asthma.
• Another to vector-borne diseases like Lyme disease and West Nile virus.
• Close with a paragraph on who is most at risk: older adults, children, outdoor workers, and people without access to air conditioning.

This structure shows clearly how climate-related causes lead to specific health effects.

Lifestyle Choices and Emissions: Everyday Examples Students Can Write About

Sometimes the best examples of cause and effect essay examples on climate change are the ones closest to home. Instead of writing only about governments and corporations, you can focus on individual choices and their climate effects.

Sample thesis
Everyday decisions about transportation, food, and home energy use collectively add up to significant greenhouse gas emissions, but small shifts in these areas can reduce a person’s carbon footprint.

Cause ideas
Explain how:

• Driving gasoline-powered cars releases carbon dioxide.
• Eating a lot of beef and lamb increases emissions because these animals produce methane and require more land.
• Using electricity generated from coal or gas plants raises household emissions.

Effect ideas
Then show effects:

• Higher personal and national emissions that contribute to global warming.
• Increased demand for fossil fuels, which slows the transition to cleaner energy.
• Potential for change: walking, biking, using public transit, or choosing plant-based meals can reduce emissions.

While this topic is more about smaller-scale causes, it still fits well as an example of a cause and effect essay on climate change. You can support your points with data from organizations like the U.S. Energy Information Administration or university sustainability centers.

A clear way to organize this essay is to:

• Introduce the idea of a personal carbon footprint.
• Spend a paragraph each on transportation, diet, and home energy use.
• Show how changes in each area could lower emissions.

This kind of essay helps readers see themselves as part of both the problem and the solution.

How to Turn These Topics into Your Own Cause and Effect Essay

Seeing examples of cause and effect essay examples on climate change is helpful, but you still need to write your own. Here’s a simple way to structure almost any of the topics above.

Start with a focused thesis
Avoid trying to cover “all of climate change.” Pick one narrow cause-effect chain, such as:

• Fossil fuel use → higher temperatures → more heat waves.
• Deforestation → more carbon and less rainfall → drought.
• Warmer climate → more mosquitoes → spread of disease.

Your thesis should name both the main cause and the main effect.

Group your causes and effects into logical paragraphs
For example, if you’re writing about extreme weather:

• One paragraph on the science of how warming affects storms.
• One paragraph on a specific hurricane or flood.
• Another paragraph on economic effects like damage costs.
• Another on human effects like displacement and mental health.

Use evidence from trusted sources
Quoting or summarizing data from sites like NOAA, EPA, the CDC, or major universities shows that your examples include more than just personal opinion. When you write about heat waves, storms, or health, you can support your claims with:

• Temperature trends over time.
• Number of disasters and cost of damages.
• Health statistics, such as hospital visits during heat waves.

Connect the dots clearly
One reason these examples of cause and effect essay examples on climate change work so well is that they don’t assume the reader will make the connections. They spell them out:

• “Because temperatures are rising, the atmosphere can hold more water vapor. As a result, when storms form, they can release heavier rainfall.”
• “As deforestation removes trees that store carbon, more carbon dioxide stays in the atmosphere, which speeds up global warming.”

Those linking phrases—“because,” “as a result,” “therefore,” “this leads to”—help your reader follow your logic.
