major threats to Antarctica - climate change

Question 1

what are the 4 major threats?

Answer 1

climate change, fishing and whaling, mineral/recourse exploitation, Tourism and scientific research

Question 2

what do warmer sea and atmospheric temperatures do?

Answer 2

melt ice sheets

Question 3

what does the melting of ice sheets cause?

Answer 3

Huge icebergs to calve into the sea - sea levels rise - global flooding

Question 4

how are plants affected by changes in temperatures?

Answer 4

adapted to the cold - invasive species adapted to higher temps could grow and colonise the environment

Question 5

how are animals affected by changes in temperatures?

Answer 5

migration patterns be disrupted - and some species (Adelie penguin) decline due to warm - affects the food chain

Question 6

Where can co2 be stored?

Answer 6

in the ice sheets

Question 7

bc co2 is stored in ice sheets what does this mean?

Answer 7

causes global temps to rise - enhance global warming

Question 8

what is the albedo effect?

Answer 8

process of white surface reflecting solar radiation back into the atmosphere

Question 9

due to less ice sheets what effect is lessened?

Answer 9

albedo effect

Question 10

what is the affect of less albedo effect?

Answer 10

more heat is absorbed into oceans - rise in ocean temps - enhance effects
