The Impact Of Climate Change On The Tropical Monsoon Climate Flashcards
1
Q
Give 4 impacts of climate change on the tropical monsoon climate
A
- Temp increase of 0.85°C, 2°C by 2100
- Increase eustatic sea level rise of 1m
- Increase coastal erosion and flooding of coastal regions
- Shift in climatic zone and change in expected weather patterns (e.g. Increased precipitation and drought in differing regions of Bangladesh)
2
Q
What is the tipping point?
A
Global climate change from one stable state to another stable state. Once tipping point has passed, irreversible transition to new state occurs
3
Q
Outline the Amazon Basin tipping point
A
- Rainfall in Amazon Basin largely from recycled moisture from rainforest
- Deforestation has reached 20%, increases atmospheric CO² due to reduced photosynthesis
- Global warming = Drought = Vegetation death
- Less effective recycling of precipitation and reduced cloud cover = Increase in local temps due to less insolation
- More rapid die-back and less CO² removed, accelerates climate change
4
Q
What will warmer sea temps lead to as a result of climate change?
A
- Melting of ice sheets and increased sea levels
- Flood low lying areas, damaging crops, displacing people
5
Q
What will extreme weather events lead to as a result of climate change?
A
- Increased evaporation, changing weather patterns, heatwave and distribution/intensity of TRS
- Destruction of homes, crops and infrastructure along with loss of life
6
Q
What will water stress lead to as a result of climate change?
A
- Affect crop yields and increase risk of drought
- Increase prices of crops
7
Q
What will conflict lead to as a result of climate change?
A
- Increased risk of disputes around resource management and migration e.g. Dafur, Sudan
8
Q
What will reduced forest coverage lead to as a result of climate change?
A
- Deforestation to make land for agriculture
- Increased desertification and loss of habitat from flooding
