Q

Outline Greenhouse effect

A
  1. Solar radiation passes through atmosphere
  2. Most absorbed by surface, warming it & lower atmosphere
  3. Radiation re-emitted in all directions by GHG molecules, casing warming.

Q

How humans effected Albedo

A
  1. Heat reducing snow & ice & soot darkening
  2. Cities radiate more heat
  3. Grass reflects more than forests.

Q

Compounding effect of water vapor

A

Warmer air = more water vapor
Water vapor is a GHG
Warmer air causes further warming

A

keep heat in during night & winter
But, sun out in summer & daytime

Q

Why ocean uncertainty?

A

Warming depends on complex patterns of currents.
Poor deep ocean data.

Q

Data suggests what human impact on warming?

A

Indicates its unlikely warming is NOT due to human activity.

17
Q

Pre-industrial main exchanges of carbon between…

A

atmosphere, ocean & terrestrial vegetation
(each stores carbon)

18
Q

Why natural CO2 fluctuation large?

A

Vegetation grows in norther spring & summer,
Dies in autumn & winter.
Less land in south -> smaller impact

19
Q

Human emissions smaller, but…

A

No counterbalance

20
Q

projected 21st century warming

A

0.2 - 5.8C

21
Q

If we burnt all FFs temperatures rise by

A

12C

22
Q

Which warms more Artic or tropics?

A

Artic

23
Q

Precipitation projected to increase over…

high latitudes

24
Q

precipitation projected to decrease over…

A

subtropic

25
Q

Rise in sea level from icecaps melting

A

4-23cm

26

West-Antartic iceshelf melt adds

A

5-6m

27
Q

East-Artic melt adds

A

60m
