Post-Exam 3: Global Warming

Question 1

global warming

Answer 1

average increase in the Earth’s climate system

Question 2

since early __th century the average increase in atm. temp has been __-__

Answer 2

20th century

0.8ºC - 1.4ºC

2/3 of increase has occurred since 1980

Question 3

greenhouse effect

Answer 3

visible light solar radiation easily penetrates the atm

when reflected it becomes infrared (longer wavelength w/ less E) so some of it can’t pass back through atm

some infrared is absorbed as thermal energy (maintains ~33ºC / 59ºF in atm)

Question 4

visible light range

Answer 4

350 - 750 nm

Question 5

increase of CO2 and methane

Answer 5

since 1750 CO2 has increased 36%

methane has increased 148%

Question 6

cause of CO2 increases

Answer 6

burning of fossil fuels

deforestation

Question 7

result of CO2 increase

Answer 7

higher sea levels due to melting of glaciers/polar ice caps

Question 8

which countries produce the most CO2?

Answer 8

China 27%

USA 14.5%

Russia 6%
