Natural Hazard
natural event with the potential to harm people and their property.
1 of 64
Natural Disaster
realisation and impacts of a natural hazard i.e deaths, injuries, disruption and damage
2 of 64
Hydro-meteorological hazards
atmospheric or hydrological process
3 of 64
Geophysical hazards
result from geological processes
4 of 64
Eathquakes
violent shaking of the earth
5 of 64
volcanoes
vent in the earths crust, lava steam and ash is expelled
6 of 64
tsunami
large wave
7 of 64
landslides
falling of soil or rock from a slope. 35 degree slope
8 of 64
avalanches
a large mass of snow, ice, sliding downwards. 35 degree slope
9 of 64
cyclones
violent rotating windstorm. 26 degrees warm air rises up, lower pressure which the air rushes to fill the space- swirling clouds.
10 of 64
drought
dry grounds
11 of 64
flooding
large amount of rain falling over a long period of time
12 of 64
tornadoes
violent rotating column of air, extending from a thunderstorm. Mosit air rises, when it meets cold air, creates an unstable atmosphere. creates a spinning affect
13 of 64
fire
fuel is ignited
14 of 64
capacity
the ability of a community to absorb and ultimately recover from the effects of a natural hazard.
15 of 64
hazards
threats to human life and property, they are unpredictable in terms of power, geographical extent and timing
16 of 64
natural hazard
a naturally occurring event that can have a significant impact upon people, property, environment such as hydro-meteorological or geophysical event
17 of 64
natural disaster
the situation when a natural hazard results in a large degree of loss or damage to life, property and prosperity.
18 of 64
risk
the risk of a disaster can be seen as a function of the hazard itself, the vulnerability of a population and their capacity to cope with that hazard.
19 of 64
vulnerability
the likelihood that a particular location or community will be affected by a hazardous event.
20 of 64
the green house effect
natural phenomenon. GHG trap some of the heat radiated from the earth. important to sustain life of earth. temperatures would be 30 degrees cooler. GHG absorb outgoing long wave radiation.
21 of 64
global warming
the observable increase in the average temperature of the earth, caused by the enhanced greenhouse effect
22 of 64
magnitude
size, represents the amount of work done
23 of 64
frequency
number of events of a given magnitude over a period of time
24 of 64
disaster hotspot
occurs when 2 or more hazard types occur in vulnerable vocations
25 of 64
IPCC
1988, decision makers and others with an objective to source info about CC
26 of 64
enhanced greenhouse effect
increased levels of gases, cause the earth's atmosphere to increase in temp.
27 of 64
climate forcing
alters global energy balance and forces the climate to change.
28 of 64
radiative forcing
relative contributions of anthropogenic activities and natural cycles to the climate change
29 of 64
anthropogenic
caused by human activity
30 of 64
UNFCCC
international agreement in combating global warming
31 of 64
insolation
incoming solar radiation
32 of 64
albedo
the ability of a surface to reflect light
33 of 64
fossil fuels
natural-hydrocarbons produce energy
34 of 64
greenhouse gases
trap out going radiation, increase atmospheric temperature.
35 of 64
climate modelling
computer programmes are used to simulate CC
36 of 64
unprecedented
unparalled, never happened before
37 of 64
direct impacts
result of changes in temperature and rainfall.
38 of 64
indirect impacts
ice sheets melt, rise in sea level, flooding, coastal erosion.
39 of 64
eustatic change
change in sea level, due to a change in the amount of water in the oceans
40 of 64
isostatic change
movement of land in repsonse to loss or gain of mass (melting icesheets leads to uplift)
41 of 64
tipping point
point at which the damage caused to the systems of the earth by global warming becomes irreversible.
42 of 64
climate change
sustained change in the average global climate
43 of 64
positive feeback
the enhancement of an effect by its own influence on the process that gives rise to it.
44 of 64
annex 1 countries
kyoto protocol identified these countries as being most responsible for global warming
45 of 64
carbon sink
carbon is stored
46 of 64
biomass fuel
derived from an organic source
47 of 64
marrakesh accords
rules agreed in 2001- operate the kyoto protocol more efficiently
48 of 64
carbon offsetting
mitigating GHG emissions
49 of 64
sustainable development
meets the needs of the present generation without compromising the ability of future generations.
50 of 64
CHP system
combined heat and power system
51 of 64
climate friendly technology
innovative or development which has little or no impact on the earths climate
52 of 64
peak emissions
GHG emissions reach their highest level
53 of 64
carbon market
buy and sell quotas, production of co2 gases.
54 of 64
carbon footprint
our impact on the environment
55 of 64
UNFCCC
united nations framework convention on climate change. 1994 step to combat GW
56 of 64
kyoto protocol
1997, international agreement that set targets for developed nations
57 of 64
carbon sequestration
natural processes, plant respriation, offset co2 emissions. Trees absorb co2 give out o2.
58 of 64
clean development mechanism
developed nations offset co2 emissions by encouraging and financing other nations
59 of 64
carbon capture
solution to climate change- GHG contained and stored safely before the can enter the atmosphere
60 of 64
adaptive capacity
the extent to which a system can cope with climate change- available human, physical and financial resources
61 of 64
climate vulnerability
the degree to which a natural or human system lacks the ability to cope with climate change
62 of 64
mitigation
reducing the output of GHG and increasing the size of GHG sinks.
63 of 64
adaptation
changing our lifestyles to cope with a new environment, rather than trying to stop climate change.
