The greenhouse effect is a natural process that warms the Earth’s surface. When sunlight hits the Earth’s atmosphere, some of the energy is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the Earth’s atmosphere and surface.
The greenhouse effect is essential to life on Earth. Without it, the Earth’s average temperature would be about 60 degrees Fahrenheit colder, making it too cold for most plants and animals to survive.
However, human activities are increasing the amount of greenhouse gases in the atmosphere, which is causing the greenhouse effect to become stronger. This is leading to global warming, which is causing a number of changes to the Earth’s climate, including rising sea levels, more extreme weather events, and changes in plant and animal life.
The following are some of the subtopics related to the greenhouse effect:
- Greenhouse gases
- Natural greenhouse effect
- Enhanced greenhouse effect
- Global warming
- Climate change
- Sea level rise
- Extreme weather events
- Changes in plant and animal life
- Mitigation and adaptation

Greenhouse gases
Greenhouse gases are gases that trap heat in the atmosphere. The main greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Greenhouse gases are essential to life on Earth because they keep the Earth’s atmosphere warm enough to support life. However, human activities are increasing the amount of greenhouse gases in the atmosphere, which is causing the greenhouse effect to become stronger. This is leading to global warming, which is causing a number of changes to the Earth’s climate, including rising sea levels, more extreme weather events, and changes in plant and animal life.
Natural greenhouse effect
The natural greenhouse effect is the process by which the Earth’s atmosphere traps heat from the sun. This process is essential to life on Earth because it keeps the Earth’s temperature warm enough to support life. The natural greenhouse effect is caused by greenhouse gases, which are gases that trap heat in the atmosphere. The main greenhouse gases are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
Enhanced greenhouse effect
The enhanced greenhouse effect is the process by which human activities are increasing the amount of greenhouse gases in the atmosphere. This is causing the greenhouse effect to become stronger, which is leading to global warming. The enhanced greenhouse effect is caused by human activities such as burning fossil fuels, deforestation, and agriculture.
Global warming
Global warming is the long-term heating of Earth’s climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere. The term is frequently used interchangeably with the term climate change, though the latter refers to both human- and naturally produced warming and the effects it has on our planet. It is most commonly measured as the average increase in Earth’s global surface temperature.
Climate change
Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term. Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors that include oceanic processes (such as oceanic circulation), variations in solar radiation received by Earth, plate tectonics and volcanic eruptions, and human-induced alterations of the natural world; these latter effects are currently causing global warming, and “climate change” is often used to describe human-specific impacts.
Sea level rise
Sea level rise is the rise in the average level of the world’s oceans. It is caused by the expansion of seawater due to warming, the melting of glaciers and ice sheets, and the extraction of groundwater. Sea level rise is a major threat to coastal communities and ecosystems around the world.
Extreme weather events
Extreme weather events are weather events that are more severe than usual. They can include hurricanes, floods, droughts, and heat waves. Extreme weather events are becoming more common and more severe due to climate change.
Changes in plant and animal life
Climate change is causing changes in plant and animal life around the world. Some species are moving to new areas in order to find suitable habitats. Others are facing extinction due to changes in temperature, precipitation, and sea level.
Mitigation and adaptation
Mitigation and adaptation are two key strategies for addressing climate change. Mitigation refers to reducing greenhouse gas emissions in order to slow the rate of climate change.
