Climate Change: Is Environmental Issue or Social Issue?

By SCIENTHESIS — P3 Lesson

Climate change refers to long-term shifts in temperature, weather patterns, and atmospheric conditions, driven largely by human activities. It is primarily caused by the increase in greenhouse gases—such as carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O)—in the atmosphere. These gases trap heat, leading to the greenhouse effect that warms the planet.

Environmental impacts

Climate change produces large-scale physical changes that affect ecosystems worldwide.

• Rising temperatures: Glacier melt and shifting climate zones.
• Sea-level rise: Threats to coastal ecosystems and communities.
• Extreme weather: More frequent storms, droughts, and heatwaves.
• Ocean acidification: Harm to marine life and coral reefs.
• Biodiversity loss: Increased extinction risk.

Social impacts

Beyond environmental effects, climate change has profound social consequences that are often unequal.

• Climate injustice: Vulnerable populations contribute least to emissions yet suffer the most.
• Health risks: Heat-related illnesses and spread of vector-borne diseases.
• Food & water security: Disrupted agriculture and supply chains threaten livelihoods.
• Displacement: Sea-level rise and disasters create migration pressures.
• Economic inequality: Fewer resources to adapt and recover.
