Understanding Climate Change: An Interactive Lesson

The Greenhouse Effect

Our atmosphere traps some of the Sun's energy, which is essential for life. However, an increase in greenhouse gases like CO2 from human activities intensifies this effect, leading to warming. Use the slider to see how increasing CO2 traps more heat.

CO2 Level: Low

Solar & Volcanic Activity

While the Sun's output and volcanic eruptions can influence climate, scientific consensus shows their impact is far less significant than that of human-caused greenhouse gas emissions in driving current long-term warming trends.

Sea Level Rise

As the planet warms, glaciers and ice sheets melt, and ocean water expands. This combination leads to a rise in global sea levels, threatening coastal communities. Adjust the slider to visualize the impact of rising waters.

Sea Level Rise: 0m

Extreme Weather Events

A warmer climate supercharges the water cycle, leading to more frequent and intense heatwaves, droughts, heavy rainfall, and powerful hurricanes. These events disrupt agriculture, damage infrastructure, and pose risks to human health.

Mitigation: Reducing Emissions

Mitigation focuses on the root cause: reducing greenhouse gas emissions. Key strategies include:

Transitioning to renewable energy sources like solar, wind, and geothermal.
Improving energy efficiency in buildings, transportation, and industry.
Adopting sustainable land use practices and preventing deforestation.

Adaptation: Preparing for Impacts

Adaptation means adjusting to the current and future effects of climate change. Examples include:

Building sea walls and elevating homes to protect against sea-level rise.
Developing drought-resistant crops to ensure food security.
Improving early warning systems for extreme weather events.
