Q
What Economical impacts are there?
A
- 5 - 10% GNP lost as mangroves and tourism lost to sea-level rise
- Coastal flooding - low lying areas in Bangladesh
- Fish stocks (pacific)
- Tourism - coastal areas declines (Maldives)
3
Q
What Social impacts are there?
A
- Severe weather causes injuries and fatalities
- Illnesses and disease: cholera, malaria
- Rising temperature case heat, stress, cardiovascular diseases
- Rising sea levels cause forced migration and civil conflict

- Extreme weather can cause allergies such as respiratory allergies and poison ivy
- Increase and new strands of malaria

A
- Warmer summers and winters
- Heatwaves
- Drought
- Flooding
- Tornadoes
- Hurricanes
7
Q
What causes sea level rise?
A
- Water expands when heated due to thermal expansion
- Melting glaciers
8
Q
What causes an increase in extreme weather events?
A
- Temperature rises make the sea warmer and hurricanes need 27°C to form
9
Q
What causes an increased frequency of river floods?
A
Greenhouse gas emissions are making extreme rainfall events more common
10
Q
What causes greater coastal erosion?
A
Seal level rise and increased storm surges
11
Q
What causes drought?
