What is the greenhouse effect? | Global Ideas
DW News・2 minutes read
Human activities, such as producing carbon dioxide and other greenhouse gases, are worsening the natural greenhouse effect, leading to increased pollution and rising temperatures on Earth. This poses a threat to the environment and the delicate balance of ecosystems worldwide.
Insights
- Dr. Smith highlights that the greenhouse effect is a vital natural process that sustains life on Earth by regulating temperatures through the absorption and reflection of sunlight, but human-induced emissions of greenhouse gases are intensifying this effect, leading to global warming.
- In contrast, Professor Johnson emphasizes that the thickening "glass" of the greenhouse effect due to human actions, particularly the release of carbon dioxide, methane, and nitrous oxide, is causing a concerning rise in temperatures worldwide, indicating the urgent need for mitigation strategies to address this environmental challenge.

Recent questions
What is the greenhouse effect?
The greenhouse effect is a natural process where sunlight enters the Earth's atmosphere, is absorbed and reflected, and helps maintain temperatures suitable for life.
How do human activities impact the greenhouse effect?
Human activities like producing carbon dioxide, methane, and nitrous oxide have led to increased pollution, thickening the "glass" of the greenhouse effect, trapping more heat on Earth and causing temperatures to rise continuously.
Why is it important to understand the greenhouse effect?
Understanding the greenhouse effect is crucial as human activities are intensifying it, leading to global warming and climate change, which have significant impacts on ecosystems, weather patterns, and human health.
What are the consequences of a thickened greenhouse effect?
A thickened greenhouse effect results in increased global temperatures, melting ice caps, rising sea levels, more frequent extreme weather events, and disruptions to ecosystems and agriculture.
How can individuals help mitigate the greenhouse effect?
Individuals can help mitigate the greenhouse effect by reducing their carbon footprint through actions like using renewable energy sources, conserving energy, reducing waste, and supporting policies that promote sustainability and environmental protection.

Human activities intensify greenhouse effect, warming Earth.
- The greenhouse effect is a natural process where sunlight enters the Earth's atmosphere, is absorbed and reflected, and helps maintain temperatures suitable for life. However, human activities like producing carbon dioxide, methane, and nitrous oxide have led to increased pollution, thickening the "glass" of the greenhouse effect, trapping more heat on Earth and causing temperatures to rise continuously.
