Hazards
Global hazards
Environmental hazards ­ the threat to the environment or human population caused by earth processes and natural
events (these include geophysical and hydro-meteorological), usually enhanced by human activity

Geophysical hazards ­ tectonic or earth processes (geological events) e.g. volcano, earthquake

Hydro-meteorological - hazards caused by hydrological (water…

the oceans leading an effect on the oceanic circulation, leading to weakening warming powers of the
North Atlantic drift and it then having less effects of the ocean current in warming the ocean)
Mitigation ­ we do have the ability to reduce the impacts of climate change, however it is…

Land pressure e.g. clearance of mangrove swamps exposes coastlines to the risk of flooding and
tsunami impacts

Trends in social/economic impacts of disasters:

Rising amount of people being affected ­ this is because of increased vulnerability and lower capacity to
cope
`Being effected' means they experience loss of livelihoods, home,…

Could lead to desertification
Food security worsened by locusts which could increase in number due to climate increase
Malaria increase (Spread of vector borne diseases) as increased temperature means the mosquitos that
spread the disease can rapidly increase in number, this puts increasing pressure on already inadequate
health systems, people…

Could reach by 2035 is our current levels of emissions continues
With business as usual approach emissions could treble by 2100 and temperature rise by 5 degrees
globally
