The greenhouse effect occurs when greenhouse gases like carbon dioxide, methane, and water vapor trap heat in Earth's atmosphere. While this effect is essential for maintaining temperatures suitable for life, human activities such as burning fossil fuels and deforestation increase greenhouse gas concentrations, leading to enhanced warming. This contributes to climate change, melting ice caps, rising sea levels, and extreme weather events. Mitigating these impacts requires reducing emissions and adopting sustainable practices.

The greenhouse effect is a natural process that helps keep the Earth warm enough for life. Here’s how it works:
- The Sun sends energy to Earth in the form of sunlight.
- The Earth absorbs this energy and warms up.
- Some of the energy is reflected back into space as heat (infrared radiation).
- Certain gases in the atmosphere, like carbon dioxide (CO₂), methane (CH₄), and water vapor, trap some of this heat and keep it from escaping into space. These gases act like the glass of a greenhouse, keeping the Earth warm.
This natural process is essential for life because, without it, the planet would be too cold. However, humans have been adding more greenhouse gases to the atmosphere by burning fossil fuels, cutting down forests, and other activities. This extra "blanket" of gases traps too much heat, leading to global warming, which is the gradual increase in Earth's average temperature.
As a result, global warming causes changes like melting ice, rising sea levels, and more extreme weather patterns.
The greenhouse effect is a natural process where certain gases, like carbon dioxide and methane, trap heat in Earth's atmosphere, maintaining a temperature suitable for life. Human activities, such as burning fossil fuels and deforestation, increase these gases, intensifying the effect and contributing to global warming. This leads to rising temperatures, melting ice caps, and disrupted weather patterns, impacting ecosystems and human societies.
The greenhouse effect is a natural process where certain gases in Earth's atmosphere, such as carbon dioxide (CO2), methane (CH4), and water vapor, trap heat from the Sun. This heat is absorbed by the Earth's surface and re-radiated as infrared radiation. Some of this radiation is trapped by greenhouse gases and reflected back toward the surface, helping to maintain Earth's temperature at a level suitable for life. However, human activities, such as burning fossil fuels and deforestation, have increased the concentration of these gases, strengthening the greenhouse effect. This enhanced effect leads to more heat being trapped, causing global temperatures to rise, a phenomenon known as global warming, which contributes to climate change and its associated impacts, such as extreme weather events and rising sea levels.
