climate change test

Question 1

define/give examples of common greenhouse gasses

Answer 1

Greenhouse gases absorb longwave infared radiation, radiating heat back out (co2, methane, water vapor)

Question 2

main sources of GHG from human activities

Answer 2

combustion of fossil fuels, rice fields and livestock, and lanfill sights

Question 3

describe the enhanced greenhouse effect

Answer 3

GHG trap reradiated heat and continue to send it back into the atmosphere, warming the earth beyond what is natural

Question 4

what 5 things are impacted by climate chage

Answer 4

temperature/precipatation, sea level, ocean/wind circulation, melting of ice, and biodiversity

Question 5

describe impacts: temperature/precipitation

Answer 5

increase in temp leads to change in rain patterns, warming oceans also leads to coral bleaching

Question 6

describe impacts: sea level

Answer 6

due to thermsl expansion and melt water

Question 7

describe impacts: : ocean/wind circulation

Answer 7

FUNDEMENTALLY DRIVEN BY TEMP DIFFERENCES

Question 8

describe impacts: melting of sea ice

Answer 8

warming waters melts from the bottom of ice, ice is not as thick as it once was

Question 9

describe impacts: ice sheets

Answer 9

antarticas ice sheets are melting rapidly, 219 billion tons per year

Question 10

describe impacts: glaciers

Answer 10

melt water contributes, more energy is absorbeed because of less ice, animal speciies die off

Question 11

describe impacts: permafrost

Answer 11

the tundra decaying leads to methane release which is a positive feedback mechanism

Question 12

describe impacts: biodiversity

Answer 12

loss of biodiversity, insects

Question 13

describe climate change impacts on human populations

Answer 13

damages to low lying countries-flooding causes damage, forced migration of people to new areas, warmer weather leads to longer/extreme droughts, negative impacts on certain industries

Question 14

describe strategies fore reduction of GHG

Answer 14

reduction of carbon footprint, more trees, investment in carbon capture,energy policies, international agreement

Question 15

describe reduction of carbon footprint

Answer 15

fewer children, less red meat, an energy efficent lifestyle

Question 16

describe stop cutting down the trees

Answer 16

reducing deforestation and increasing reforestation

Question 17

describe investment in carbon capture

Answer 17

could be potentially risky for our future

Question 18

describe changing energy policies

Answer 18

reducing use of fossil fuels, alternative forms of energy (bike/public transport)

Question 19

2 policies that could help involving urban design

Answer 19

underground railways to reduce traffic and promotic electric/hybrid cars

Question 20

what are the two climate agreements

Answer 20

kyoto protocol (1997)
The paris climate accord

Question 21

geoengineering staratgeies

Answer 21

solar radiation management stratagies- albedo enhancement, space reflectors, stratospheric aersols
