ESS topic 6 test

what is the atmosphere made out of in descending order of concentration

nitorgen, oxygen, argon,

stratosphere

ozone layer

troposphere

weather

how does air move

high pressure → low pressure

what does wind strength depend on

air pressure

describe cold air

• molecules move slow

• close together

unequal heating and latitude

leads to atmospheric circulation

where is there a deficit of energy

towards the poles

where is there excess energy

38 S to 38 N

what are the bad GHGs

• carbon dioxide

• methane

• nitrous oxide

• water vapor

what is a clear substance clack carbon can be covered in

sulfuric acid 9this is like a magnifying glas)

fresh vs old soot

fresh=more reflective

old=absorbs

what is radioactive forcing

measure the incoming solar radiation and outgoing longwave radiation

positive radiative forcing

earth is receiving more energy than it is radiating back to space

infrared radiation

short wave UV reflected off of earth

most important GHGs

carbon dioxide

methane (CH4)

positive feedback

amplifies chance and drives system to new equalibrium

positive feedback example

1. melting ice caps

2. lowers albedo affect

3. less reflection of the sun

4. more heating of the earth

5. more ice melts

negative feed back

prevents or lessens change to equalibrium

negative feedback example

1. earth warms

2. increase in evaporation producing more clouds

3. increased albedo reflecting light away from earth

4. temperatures fall

5. evaporation rates fall

high albedo vs low albedo

high- reflects

low- absorbs

bjorn lomborg

• democratic pov

• global warming is due to poverty

extinction rebellion

UK, non violent environmental movement

IPCC

deals with global warming in groups:

1. scientific notes

2. research on impact and options fro adaptation

3. research for limiting GHGs and mitigation

kyoto protocol

reduce GHG emissions

paris agreement

limit rise in global temp
