## Slide 1: The Greenhouse Effect
- Understanding the delicate balance of Earth's atmosphere.

## Slide 2: What is the Greenhouse Effect?
- A natural process that maintains Earth's temperature to support life.
- Atmospheric gases trap reflected heat from the surface.

## Slide 3: How It Works: The Energy Balance
- Sunlight warms the surface.
- The surface releases infrared heat energy.
- Greenhouse gases (GHGs) absorb and re-radiate this heat.

## Slide 4: The Keeling Curve (1960 - 2024)
- Atmospheric CO₂ has risen from ~316 ppm in 1960 to ~425 ppm in 2024.
- The acceleration of CO₂ levels correlates with industrialization.

## Slide 5: Human Causes of Enhanced Warming
- **Fossil Fuels**: Coal, oil, and gas release massive CO₂.
- **Deforestation**: Fewer trees reduce carbon absorption.
- **Agriculture**: Livestock and fertilizers produce Methane (CH₄) and Nitrous Oxide.

## Slide 6: Environmental Impacts
- Rising global temperatures are causing glacier retreat and sea-level rise.

## Slide 7: Extreme Weather Events
- Increased incidence of: Heatwaves (95 index), Floods (80), Wildfires (85), and Hurricanes (75).

## Slide 8: Solution: Transition to Renewables
- **Solar & Wind**: Zero-emissions energy sources.
- **Electrification**: Switching to electric cars and heating systems.

## Slide 9: Solution: Nature-Based Action
- Protecting forests and oceans as natural 'carbon sinks'.
- Focus on reforestation and conservation.

## Slide 10: A Sustainable Future is Possible
- Reducing emissions today leads to a stable climate for the future.
