A
Orbital changes
Volcanic activity
Solar output
Human activities – deforestation, farming, burning fossil feels
3
Q
Effects of climate change
A
Environmental - ice melting causing sea levels to rise, loss of polar habitats, species declining, biodiversity decreasing
People – migration and overcrowding due to flooding, Struggling to supply water due to change in rainfall, farming (lower crop yield) leading to malnutrition, whether more extreme
4
Q
Managing climate change
A
Mitigation (how to reduce climate change) Planting trees International agreements Carbon capture Alternative energy production Adaptation – farming- new crops produced Water supply – nets collect mist, meters collect rainwater Rising sea levels – build flood defences
