clomate change Flashcards
human causes of climate change
-burning fossil fuels co2
-increased car ownership
-deforestation, less co2 being absorbed, burning of wood releases co2
-fridges disposed incorrectly release CFCS, when the foam insulation inside them gets torn
-fertilisers, nitrous oxide
impacts of climate change
-more extreme and variable weather like flooding and droughts, more frequent and intense hurricanes
-possibly up to 40million more people in africa being exposed to malaria
-prolonged dry season can lead to forrest fires, australian bush fires
-increase in sea temps causes coral bleaching, coral dies, loss of habitat for marine life
-extinction of land species due to habitat loss
-low lying coastal areas will experience flooding, bangladesh, loss of land for farming, displacement
management of climate change
-reduce, reuse recycle, landfill sites, reduce amount of methane
-switch lights off, insulate homes
-use public transport, electric cars
-older fridges should be disposed of carefully so CFCs don’t escape, new fridges don’t emit CFCs
-govt increases the use of renewable energy like wind farms
-paris agreement
-preparing for extreme weather events like flooding, defences can be built to hold back water, thames flood barrier
EFFECTIVENESS OF TJINGS MANAGING CLIMATE CHANGE
-thames barrier
✅predicted to provide protection from one in. thousand year flood events
❌a second barrier may need to be built by 2070, and advanced warning systems are needed
-LINDON DESALINISATION PLANT
❌only intefmnded to be used in periods of extreme draught due to high operational costs
-HOSE PIPE BANS bc of draught during periods of extended rainfall
❌difficult to enforce
-scotland increasing renewable energy production
✅which were meeting 50% of the demand by the end of 2014
❌opposition to wind farms bc of effects on wildlife, difficult to meet future targets
