The major factors that play a role in global warming are:

1. Human Activity:
- The burning of fossil fuels like coal, oil, and natural gas for energy production releases greenhouse gases such as carbon dioxide into the atmosphere.
- Deforestation, primarily for agriculture or urban development, reduces the number of trees available to absorb carbon dioxide, contributing to increased greenhouse gas levels.
- Industrial processes, transportation, and agriculture also release greenhouse gases, exacerbating the greenhouse effect and leading to global warming.

2. Natural Factors:
- Natural occurrences such as volcanic eruptions release large amounts of gases and particles into the atmosphere, affecting the Earth's climate.
- Changes in solar radiation and volcanic activity can influence global temperatures, although their impact is less significant compared to human activities.

In summary, the primary factors contributing to global warming are human activities, particularly the release of greenhouse gases, and to a lesser extent, natural factors such as volcanic eruptions and solar radiation variations.
