Greenhouse Effect

The greenhouse effect occurs when heat from the Earth is trapped by gases in the atmosphere, leading to a rise in temperature.

• Carbon Dioxide (CO2)
• Methane (CH4)
• Nitrous Oxide (N2O)

---

Paris Agreement

The Paris Agreement (2015) is an international treaty to limit global temperature rise below 2°C.

• Focus on reducing carbon emissions
• Global cooperation for climate action

---

Carbon Emissions

Carbon emissions mainly come from industries, vehicles, and fossil fuels.

• Major cause of global warming
• Leads to environmental damage

---

Renewable Energy

Renewable energy sources like solar and wind help reduce pollution.

• Clean and sustainable
• Key solution to climate change

---

Exam Focus Points

• Greenhouse Effect → Heat trapping
• Paris Agreement → Climate control
• Carbon Emissions → Pollution source
• Renewable Energy → Solution
