1. Human Impacts on Climate

2. which absorbs ultraviolet (UV)
Name the primary gas
which absorbs ultraviolet (UV)
from the sun.
ozone

3. 1. Ozone hole
Humans have added chlorofluorocarbons to atmosphere which destroy ozone and have created a hole over Antarctica and southern South America

4. Why is the ozone layer important?
Sun's Energy & Climate
Why is the ozone
layer important?
It protects the Earth from UV which damages crops and
causes cancer in humans.

5. Ozone hole over Antarctica

6. 2. Greenhouse Gas Emissions
Greenhouse gases are:
CO2, methane, water vapor
Infrared radiation or heat gets trapped by the addition of these gases (Greenhouse effect)

7. What is the issue?
Average global temperatures are warming

8. How will it affect you?
1. Glaciers are melting, sea levels are rising

9. Tanzania

11. 2. Increase in extreme weather events

16. 3. Chemistry of Ocean water
Becoming more acidic
When warm waters persist, corals bleach and become less able to combat disease. As climate change continues, bleaching is predicted to become more common.

17. 4. Ecosystems Will be affected  extinction of species
Monarch butterfly – soon to be on endangered species list

18. 5. Increase of infectious disease
Malaria
Dengue fever
Tick borne diseases (Lyme)

19. Warming is a natural process but humans are speeding up the process
