Week 3 Flashcards
1
Q
What will our future climate look like
A
- Global surface temperature change relative to 1850-1900
- Projections show a chart with upwards trend
- The future climate depends on us
2
Q
Temperature in North America
A
- Land areas warm up more than areas
- Higher altitude warms quicker than lower
- Health can be sensitive to extreme weather events, so climate projections include the ability to output the frequency of heat events, illustrated here as days with a high temperature above some threshold
3
Q
Projected Hot Days and Night for Cities in Canada
A
- Hot night can be important to health via our sleep quality
4
Q
Why the concern?
A
- Significant correlation between annual temperature anomalies and annual population based rate for emergency department heat illness visits.
5
Q
Heat as a Hazard
A
- Heat is the most hazardous weather event
6
Q
Heatwave events
A
- European summer temperature 1500-2010
- With climate change the distribution will shift to the right
- Russian heat wave: 70,000 deaths
- European Heat wave: 55,000 deaths]
7
Q
2003 Heatwave and Climate Change
A
- Impacts are magnified in urban areas
8
Q
Spatial patterns with Climate Change
A
- Number of days per year above “deadly” threshold
- Exposure of populations to heat is increasing with climate change
- Deadly = climate conditions (temperature and humidity) projected to cause death
9
Q
Chicago Heat Wave Video
A
- 126 degrees Fahrenheit to 52 celsius
- 1995 Killer heat wave
- People who died
- Targeted the most vulnerable in the city
- Disproportionately affected people
