Climate Change – Causes, Effects & Solutions.pptx

this is presentation

1. Climate Change: Understanding the Crisis Climate change refers to long-term shifts in temperatures and weather patterns, mainly caused by human activities. While climate variations are natural, the pace and scale of change since the Industrial Revolution are unprecedented .

2. What is Causing Climate Change? Greenhouse gas emissions (CO₂, CH₄, N₂O) Fossil fuel combustion (coal, oil, gas) Deforestation and land use changes Industrial activities and agriculture Urbanization and transportation emissions

3. The Greenhouse Effect The greenhouse effect occurs when gases trap the sun’s heat in Earth’s atmosphere, keeping the planet warm. Human activities have increased these gases, intensifying the effect and causing global warming.

4. Evidence of Climate Change Rising global temperatures Melting glaciers and polar ice caps Rising sea levels More frequent and intense natural disasters Shifting weather patterns and extreme heatwaves

5. Impacts on the Environment Coral bleaching due to ocean warming Habitat loss for Arctic species Disruption of ecosystems Increased risk of wildfires and droughts Ocean acidification threatening marine life
