Climate vs Weather
Weather is short-term atmospheric conditions. Climate is long-term patterns over decades. Climate change refers to significant shifts in global or regional climate patterns, including rising average temperatures.
The Greenhouse Effect
Greenhouse gases (CO₂, methane, water vapor) trap heat in the atmosphere. Natural greenhouse effect keeps Earth habitable. Increased concentrations from burning fossil fuels enhance trapping and warm the planet.
Evidence and Impacts
Ice cores, temperature records, and sea level rise support warming trends. Impacts include more extreme weather, ocean acidification, habitat loss, and shifts in species ranges. Vulnerable communities face disproportionate effects.
Mitigation and Adaptation
Mitigation reduces emissions: renewable energy, efficiency, reforestation. Adaptation prepares for changes: flood barriers, drought-resistant crops. Individual and policy actions both matter. Sustainability balances environmental, economic, and social needs.
