🌊 Consequences of Climate Change
Physical Changes (SIRF)
- Sea levels rise — coastal flooding, displacement of communities
- Ice caps melt — contributes to sea level rise, changes albedo
- Rainfall changes — more droughts in some regions, more flooding in others
- Flooding increases — more extreme weather events
Ecological Impacts
- Coral reef bleaching from warmer, more acidic oceans
- Species migration poleward and to higher altitudes
- Arctic ecosystem disruption
- Changes in food webs
Human Impacts
- Agricultural productivity changes (some regions gain, many lose)
- Water stress in already-arid regions
- Coastal communities threatened by flooding
- Economic costs of adaptation and extreme events
