33. Biodiversity and Human Well-Being II

Question 1

causes of global climate change

Answer 1

Atmospheric CO2 Over The Past 1,000 years shows rapid increase in starting in 1800s - atmosphere controls the climate

Question 2

current impacts of global climate change

Answer 2

climate affects ecosystem services such as crop yield and distribution of organisms

Question 3

future consequences of global climate change

Answer 3

• change in average temperature, precipitation, and sea level
• change in food availability

Question 4

climate change actions

Answer 4

• Alberta has a lot of solar and wind potential
• policy change
• personal action/knowledge

Question 5

controlling invasive species through local action to sustain ecosystem services (lionfish case study)

Answer 5

The goal: Make the most effective use of limited resources to reduce lionfish population numbers, involving consumers, restaurants, seafood distributors, and jewellers

Question 6

human impacts on biodiversity and ecosystem services

Answer 6

1. habitat loss (degradation and fragmentation)
2. climate change
3. over-exploitation
4. pollution
5. invasive species

Question 7

greenhouse gases

Answer 7

* Carbon dioxide (CO2)
• Water vapor (H2O)
• Methane (CH4) = 21 CO2
• Nitrous Oxide (N2O) = 310 CO2
• Ozone (O3) = 1,000 CO2
• Chlorofluorocarbons (CFC’s) = 4,750 CO2

Question 8

International Panel on Climate Change (IPCC)

Answer 8

• Originally created bythe UN and the World Meteorological Organization.
• Publish periodical reports on global climate change.

Question 9

difference between climate change and global warming

Answer 9

The climate of each location on the Earth is
going to change differently because of global
warming. On average though, the planet is warmer.

Question 10

drivers of greenhouse gas emissions

Answer 10

• mainly electricity/heat, industry, and agriculture/forestry
• 7 countries contribute more than all others combined

Question 11

biotic invaders

Answer 11

species that establish a new range in which they
proliferate, spread, and persist to the detriment of the
environment.
