Arctic

Question 1

Extremity

Answer 1

Quite extreme
Parts are 20°c warmer than they should be
Ocean temperatures are 4°c warmer than usual

Question 2

Effects (positive feedback)

Answer 2

Positive feedback loop - less ice so more vegetation, so more suns energy absorbed (albedo) so gets warmer, and so on…

Question 3

Effects (permafrost)

Answer 3

As it gets warmer, permafrost thaws, methane and co2 are produces, greenhouse gasses, so it gets warmer, and so on…
The release of methane can increase the temp by up to 0.5°c and it is 30x stronger insulator than co2

Question 4

Effects (sea exposed)

Answer 4

Ice melts so more dark ocean exposed so less suns energy reflected (albedo) so it absorbs heat so it gets hotter

Question 5

Other effects

Answer 5

Communities like vuntut gwitchin, way of life threatened
Settlements may be threatened
Ecosystems threatened (polar bears fish a lot of the time but need to rest on ice, number of icebergs has decreased.)
Monsoon over Asia could be disturbed tpdutpe to warmer oceans
