Week 6: Climate Change

Question 1

Changes in meteorological factors

Answer 1

Temperature
Humidity 
Rainfall
Atmospheric particle counts
Wind

Question 2

Great ocean conveyor belt

Answer 2

Decrease in warm water flow due to increased warming

Question 3

Impacts of climate change on human health

Answer 3

40% of world deaths due to environmental degradation

Question 4

Primary causal pathway

Answer 4

Direct biological consequences of heat waves, extreme weather events, and temperature-enhanced levels of urban air pollutants

Question 5

Secondary causal pathway

Answer 5

Risks mediated by changes in biophysically and ecologically based processes and systems, particularly food yields, water flows, infectious-disease vectors and intermediate-host ecology

Question 6

Tertiary causal pathway

Answer 6

More diffuse effects (mental health problems in failing farm communities, displaced groups, disadvantaged indigenous and minority ethnic groups)
Consequences of tension and conflict owing to climate change-related declines in basic resources (water, food, timber, living space)
