Question

(Select] Question 42 Match each tipping point to the most likely impact (1 point each): Melting permafrost [Choose] Arctic sea ice loss leading to loss of Atlantic deep water formation [Choose] Instability of the West Antarctic Ice Sheet [Choose) Boreal Forest Dieback [Choose] Increased ocean warming [Choose] MacBook Air 80 888 8

Answer 1

• Melting permafrost - release of methane

• Arctic sea ice loss leading to loss of Atlantic deep water formation - reduced ocean circulation via the great ocean conveyor belt

• Instability of the west Antarctic ice sheet = sea level rise​​​​​​​

• Boreal forest dieback - reduced carbon sequestration

​​​​​​​

• Increased ocean warming - release of methane hydrates from the ocean
