Lecture 14: climate change Flashcards
Direct ways climate change effects health
Heat waves Floods and storms and draughts Water scarcity and quality Communicable diseases, gated by vectors (insects) Air pollution Changing agriculture
Indirect ways climate change effects health
Migration (climate refugees)
Insecurity
Economic effects
Heat ways
Kills thousands every year
India is particularly effected
Since 2010, more people live in cities than not in cities
o Cities have pavements, less tress, therefore you are more susceptible to heat waves
o Increasing local carbon dioxide production
Heave waves kill more than deadly storms
Floods and Storms
Affects poor people disproportionately
Most poor countries live adjacent to bodies of water
Places most susceptible to flooding
o Islands, such as the Nile in Egypt, Bangladesh, Marshall and Tuvalu and Maldives
Communicable diseases
Growth of swamps have always been cyclical, however now it is not, so we can no longer predict
Clustering people into tighter groups making them more susceptible to things
Dengue zone increasing as vectors move
Water Quality and Scarcity
Well water is underwater river system that affect everything
No water in the rural areas, so people rush to the urban slums, same issue and more
Synergistic effects that play into mobility, geography and more
Air Pollution
Pollution effects can be local,
The hotter the temperature the higher amount of pollutants will stick around
Exasperating in cities with poor planning
Agriculture
Poor agriculture leads to poor nutrition leads to poor health
Insects are changing, so we don’t know what pesticides to use
Building on good land resulting in less land to grow food
Plants are already at their limits of tolerance for environmental conditions
Migration
The one that gets politicians interested
Refugee populations are weak and undernourished causing the a health concern
Insecurity
War
o South Asian (India, Pakistan, Bangladesh) share one source of water
In Canada, our wealth is primarily built on service,
o A lot of the wealthiest nations are built on a service economy
o We don’t manufacture a lot of things, therefore we don’t need running water
Any time you make interventions in your water supplies (Dams) your effecting other countries and are at risk for conflict
Correlation of war and temperature we think has something to do with water supply
Economic Effects
Done for wealthy countries, don’t know the analysis done on poor countries
Coral bleaching done by UV from the sun and the collapse of world’s fisheries
Synergistic Effects
Drought causes people to migrate where they are susceptible to new diseases
Floods can cause cholera and diarrhea and damage to infrastructure
WHO’s position on climate change
The political force denying climate change is the human involvement piece
What is being done
Creating a global fund for analysis so that poor countries can be used as a model
Global disease surveillance
International bodies for managing resources
Research – being able to predict changes in vectors and climate
Atlas of Health and Climate
Book in 2020 to show how the world is changing as a result of climate
If you stopped everything right now, temperature will still rise because there is a lag
o Doesn’t mean it is to late, but that it will take a while for it to get better and it might not get better in our lifetime
