atmosphere and oceans over the past 100 years
3.Effects• Animals- disturbed
habitat ,loss of food• Humans Loss of culture
and way of life for Inuit peoples
4. Rising sea levels
• Causes• Melting glaciers and
icecaps• Thermal expansion
• Effects• populations displaced
due to flooding of large coastal cities
5.Acidification Oceans
• Oceans absorb half the CO2 from fossil fuel use.
• Dissolved CO2 forms carbonic acid and so Ph goes down.
• Corals and other shelled organisms can’t build shells
• Fish and plankton reproduction decreases
• Commercial fishing affected
6.Health
• Temperature increase • Outbreak of disease
(hantavirus,lyme disease, malaryia,plague)
• Dust, mold ,pollen increase therefore more asthma and allergic responses
• Rainfall increase• Waterborne disease
increase• Microscopic organisms
live in water supply• Eg E. Coli
7. Heat distribution
• A) wind an precipitation patterns
• B) Most of Canada has experienced increased precipitation
8 Dessertification
• A) Loss of crops and subsequent food shortages
• B) by 2050, 75% of the world will experience water shortages
9 Hurricanes
• A) Hurricanes form over tropical oceans during the late summer and early fall
• As surface temperature of water rises so does the hurricanes intensity
