Impacts of climate change on people and places, including health hazards, migration and ocean transport routes.
1. Health Hazards
a) Infographic task For your allocated infographic do each of the following:
Study the infographic and make notes which will allow you to explain and elaborate on what it shows to a group of your peers (each infographic links to further explanation)
Evaluate the effectiveness of the infographic - what are its strengths and weaknesses?
b) Small scale research We can divide the impacts of climate change on health into several categories, some of which are listed below. Use the web links to write a paragraph to explain each of the impacts listed. Do you need to add any other categories based on what you have learned?
Impacts of extreme heat
Natural disasters eg increasing frequency and intensity of storm events
Changing rainfall patterns eg increased incidence of floods, impacts on freshwater supply
Patterns of infection, eg areas in which malaria is prevalent
Changes in the seasons in which diseases might be transmitted
Impacts on food supply and so undernutrition and malnutrition
c) Reading/notes task (use p179 of the textbook as a starting point) 1. Explain how the following conditions are linked to atmospheric temperatures:
Eruthromelalgia
Raynaud's Syndrome
Mental Health issues
Suicide
2. Why do infectious diseases spread more easily in temperature extremes? 3. How many people do mosquitoes kill annually through Malaria and Dengue? 4. What factors increase the dangers of this number rising? 5. What hazards to humans do red tides and zooplankton pose? 6. What impact on water resources could occur in Sub-Saharan Africa and the Middle East?
Climate change is already causing migrations and it seems likely that the scale will increase dramatically. These migrations may occur for a range of reasons including:
Low-lying island nations may become wholly uninhabitable if sea-levels continue to rise. People in Micronesia, the Caribbean, the Seychelles, Mauritius, and others, may require outright relocation.
Larger countries with significant coastal populations, such as India and Bangladesh, may be able to accommodate internal migration from areas affected by sea rise but will need significant assistance in doing so.
Rapid-onset natural disasters, such as hurricanes and typhoons, will force people to seek temporary shelter elsewhere in the country or across borders.
Slowly unfolding disasters, including desertification and water shortages, will harm economic development and force people out of climate-sensitive livelihoods.
Climate change may exacerbate—if not directly cause--violent conflict within and between states by intensifying competition for resources, prompting people to flee their homes.
b) Kiribati - go back to our work on Population on Kiribati. Make sure you are clear on how we can link this to this section on climate change and migration!
