- Climate Change Impacts
- Sea Level Rise
- Water stored as ice returns back to oceans
- Adds to rising sea levels (eustatic change)
- If all ice sheets melted, 80 metre rise
- Adds to rising sea levels (eustatic change)
- Global warming leads to thermal expansion
- Increased water volume
- For every 1'C increase, up to 80cm rise
- Increased water volume
- Serious affect on vulnerable Pacific Islands
- Small in size, dense populations, low elevation, remote
- eg. Marshall Islands / Tuvalu
- Small in size, dense populations, low elevation, remote
- Water stored as ice returns back to oceans
- Permafrost Thawing
- Permanently frozen ground for at least 2 years
- Natural CO2 sinks
- If thawed, CO2 stored as organic material in soil realeased
- Tipping Point
- Temperature rise could cause irreversible changes to earth
- Through positive feedback
- Melting of sea ice into water
- Lower albedo, more energy absorbed
- Warms water, melting more ice
- Lower albedo, more energy absorbed
- Impacts already caused speed up impacts
- Melting of sea ice into water
- Through positive feedback
- Temperature rise could cause irreversible changes to earth
- Extreme Weather Events
- Increasing ocean temperature
- Increased risk of tropical cyclones
- Wider area of risk
- Increased risk of tropical cyclones
- Increasing ocean temperature
- Climatic Regions
- Cold polar regions shrinking
- Species forced to migrate to find sustainable climate and food
- Some areas are not viable for agriculture
- Sea Level Rise
