Climate Change — lesson overview
Greenhouse effect and climate
The natural greenhouse effect helps maintain Earth’s temperature by influencing the escape of outgoing infrared energy.
Increased concentrations of greenhouse gases can strengthen warming; the mechanism is distinct from depletion of stratospheric ozone.
Climate change concerns shifts in the statistics of climate over time, not simply any single unusual weather event.
Impacts and attribution
Warming can affect sea level, ice, rainfall patterns, ecosystems and extremes through interacting processes. Effects vary by location and exposure.
Attribution investigates the contribution of different causes to observed changes using evidence and models; it is not inferred solely from one hot day.
Risk combines climatic hazards with exposure and vulnerability, so social and infrastructural conditions influence consequences.
Responses
Mitigation reduces emissions or enhances sinks. Adaptation reduces vulnerability or adjusts systems to actual or expected impacts.
A measure can contribute to both goals, but the concepts remain distinct. Flood-resilient infrastructure mainly addresses adaptation; low-emission energy can support mitigation.
Policy evaluation should consider effectiveness, fairness, cost, implementation and interactions with development priorities.
