1. How does the they create emission scenarios
IPCC estimate fu-
ture emissions?
2. What are emis- assumptions about pop growth, economic growth, energy use, land use changes,
sions scenarios resource availability, pace and direction of technological change, types of energy
based on? usage favored by changing tech's
3. What is the A2 business as usual - moderate econ growth, pop increasing, large diff in standards
scenario? of living btw regions, tech change is relatively slow
4. What is the A1B technological progress - large econ growth, decreasing inequality btw regions,
scenario? pop grows but then declines, new tech means greater efficiency and new energy
sources
5. What is the b1 a greener world - same econ and pop assumptions as A1B but world rapidly
scenario? transitions to global service and information economy with increasing efficiency
and less intense production of material goods
6. What is the differ- emissions can decline a long time before concentraion declines
ence btw emis-
sions and con-
centrations?
7. What are the averages over many models, more warming over land in n hem, no uniform
projected temp warming, relative prob means more uncertain further into the future
changes?
8. What 2 questions how will climate forcings change?
do we need to how will the climate respond to forcings?
answer to predict
future climates?

9. How does the increase in greenhouse gases mean more radiation to earth/inc in temp favors
hydrologic cy- loss of surface heat through evap>increase in evap>increase in precip

work?
10. What are four cli- hydrologic cycle intensification, extreme weather events, melting glaciers and ice
mate change im- sheets, sea level rise
pacts on earth's
physical sys- warmer>more evap>more precip>more runoff
tems? hydrologic rate will increase with temp
more evap is uniform but precip increase is not
11. Where will pre- over poles, decrease over subtropics
cipitation in-
crease? wet areas get wetter and dry get drier
12. Why do we ex- due to hydrologic cycle intensification, larger areas of planet in drought conditions,
pect to see in- climate change may make hurricanes more likely but would result in fewer hitting
crease in extreme ht US
weather events?
13. What do we know glacial melt is obvious and will continue, ice sheet melt area is increasing but there
about melt? is uncertainty about the fate of the Greenland and antarctic ice sheets
14. What do we know it has increased 120m since end of last glaciation but has been relatively constan
about sea level for the past 7000 years
rise since the last
glaciation?
15. How has sea lev- steady increase of about 20 cm over last 100 years
el changed in the
last 100 years?
