Global hazards

I will be creating quick refresher flash cards for every topic of unit 1: global challenges. 

Good luck for your exam!

?
Hydro-meterological hazards
Floods, storms, bush fires, droughts and blizzards. (Running water)
1 of 15
Geophysical
Tsunamis, landslides, earthquakes and volcanoes. (Land processes)
2 of 15
Disaster risk equation
Risk = hazard x vulnerability/capacity to cope.
3 of 15
Natural hazard definition
Natural event or process which affects people.
4 of 15
Disaster definition
EM-DAT database: 10+ dead, 100+affected, emergency and aid.
5 of 15
1. Climate change is a global problem
Various impacts.
6 of 15
2. Chronic
Slow onset and on-going adverse effects.
7 of 15
3. Range of impacts
E.g. water availability and food security
8 of 15
4. Unpredictable
Hard to predict the strength and effect of feedback mechanisms and mitigation.
9 of 15
5. Indirect impacts
E.g. flooding from thermal expansion which causes a rising sea levels.
10 of 15
6. Modelling
Has to take into different aspects and very unpredictable
11 of 15
7. Separate the effects
Distinguish between global warming and atmospheric/oceanic oscillations, e.g. el Nino.
12 of 15
8. Global solutions
Requires whole world: coordination and agreement. Compromises economic development; two speed world.
13 of 15
9. Contested
Only recently recognised as oil companies argued that it was natural.
14 of 15
10. Costly
It will require a huge sum for both adaption as well as mitigation,
