Impacts of Climate Change
meteorological/climate hazards
sea levels rise
changing climates
extreme weather
tropical storms
force increase
intensity increase
flooding
frequency increase
tornadoes
heatwaves
40*C for weeks - thought to have killed 13000 people in France (August 2003)
droughts
increasing desertification at an alarming rate
cold snaps
warmer seas
change in the distribution of ecosystems
farming able to occur further towards the poles and to higher altitudes
wetter climate
resources (oil, natural gas, minerals) become accessible and able to be exploited
some areas may no longer be able to accommodate farming due to heat
shrinking of glaciers
large areas of ice sheets are breaking off as temperatures increase
reduced employment opportunities
costa areas contain a significant amount of the world's economic wealth is generated & located here as well
economic impacts
migration encouraged
huge negative impact on employment
it is unlikely most jobs and economic opportunities can be wholly replaced in other locations
costal farmland, cities, tourist resorts and ports are abandoned
changing settlement patterns
migration
people evacuated
jobs and economy impacted
social impacts
health (disease, food supply, heat related illness)
change in distributions of many diseases
malaria will occur at higher latitudes and altitudes
world will become drier, water will become scarcer
people forced to use unclean water
water-borne diseases will become increasingly frequent and widespread
increase in mortality rates
upheaval and movement of people and economic activities cause human distress and insecurity
sea level rise
retreat from the coast
threat to major coastal cities (Miami etc)
migration
people have to resettle, economic activities and wealth effected
relocation of economic activities
new settlements away from he coasts
health and well-being
temperature change
sea level has risen by 20cm since 1880
range of 1-2 meter increase by 2100
deforestation
lack of trees, increase in greenhouse gasses
protests against deforestation come most strongly from the governments and people of developed countries
most developing countries ask why they should be denied this chance to develop their economies
sustainable management of the tropical rainforest may help the developed countries
