What is the greenhouse effect?
Warming of the earth’s atmosphere as a result of greenhouse gases (or CO2) trapping
thermal (heat) energy
Teacher Version
b.
/2
TI
How does it occur? (/2 TI)
 CO2 and other Greenhouse Gases (GHG) are responsible
 they form a layer (primarily in the troposphere)
 they allow solar radiation to enter the earth
 but block the outgoing heat from leaving the atmosphere
 thereby heating of the atmosphere (as a whole) and the oceans and the earth.
2. Name and briefly describe and effect of climate change on
a. humans
 increased heat related diseases (e.g. increased heat stroke in the elderly in summer)
/2
 loss of fresh water rivers to supply India and China as glaciers melt
TI
 or other logical answer
/2
TI
b. natural ecosystems
 glaciers melting
 ice caps melting
 new species moving northward (in northern hemisphere) into new ecosystems
 or other logical answer
3. List and briefly explain
a. an initiative that exists to reduce climate change.
anything logical, could include
 reducing use of fossil fuels
IDENTIFY/NAME an initiative

using
public
transportation
Briefly EXPLAIN it
/2
 planting more trees
KU
 carbon taxes

b. why you think this does/does not work.
 student should be able to explain their answer by making reference to either a
/2
reduction in the production of greenhouse gases (or just CO2) and/or an
A
increase in Carbon Sequestration.
