Climate Change Flashcards
sea levels change for two main reasons
subsistence of the coastline (coastal areas sinking due to excessive groundwater extraction- makes sea level relatively higher)
increase in water volume of the ocean (changes due to either thermal expansion or addition of extra water from land stores)
case study to use for climate change
the Maldives (from GCSE folder)
how can SLR affect water supply
salt water can contaminate groundwater (where we get most drinking water and crop water from- can also have vast effects on biodiversity as species that are not halophylic will not survive)
how could SLR affect us for industry
major rail and road links, as well as several major power stations are located on low lying ground. number of cities along the coastline will be affected- eg London and Hull– severe economic and social impact
how will SLR affect erosion rates for cliffs
increase rates of soft-cliff erosion through accelerated rates of SLR and changes in wave conditions
which communities are most at risk of the effects of climate change in the UK
coastal communities especially those who rely on it for residence, communications and economic and social means
socio-economic issues for coastal communities which make them very vulnerable to climate change
high proportions of older residents low employment levels high seasonality of work, physical isolation poor transport links.
why are people in disadvantaged communities along the coast unaware of the impacts of climate change
more concerned about day to day issues such as income and employment. residents who have experienced major storms are more aware
benefits of living by the coast (4)
recreational activities (eg kayaking, sailing, swimming) helps improve health
air along the coast is better for health (cleaner)- can decrease your stress level and improve mood
make lots of money through tourism- but is seasonal
swimming in the sea- health benefits- salt water enhances the immune system, hydrates skin and boosts circulation
