Question
**Question:** What specific changes to the Earth’s greenhouse effect (atmospheric composition) affect global warming?

[Explaination:]
This question explores how alterations in the composition of Earth's atmosphere can influence global warming through the greenhouse effect. The greenhouse effect is a natural process where certain gases in the atmosphere trap heat, keeping the planet warm. Increasing concentrations of greenhouse gases such as carbon dioxide, methane, and nitrous oxide enhance this effect, leading to a rise in Earth's average surface temperature.

#### Key Points:
- **Greenhouse Gases:** These include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. Human activities such as burning fossil fuels, deforestation, and industrial processes increase these gases.
- **Impact on Temperature:** Higher concentrations of greenhouse gases increase the heat trapped by the atmosphere, raising global temperatures. This contributes to climate change, resulting in extreme weather, rising sea levels, and ecosystem disruptions.
- **Feedback Loops:** Melting ice reduces the Earth's albedo, meaning less sunlight is reflected and more is absorbed, further warming the planet. Thawing permafrost releases methane, a potent greenhouse gas, exacerbating the effect.
