Question 1

Environmental impact (case study artic)

Answer 1

Melting of artic sea ice and the Greenland ice contribute to rising sea levels globally
Changes in ocean currents by adding freshwater, lowering salinity and disrupting the sinking of cold water that drives global circulation
Thawing permafrost releases significant amounts of carbon dioxide and methane

Question 2

Opens new shipping routes in the artic, boosting trade and benefiting local ports in Siberia
Exploitation of natural resources becomes more accessible
Infrastructure built on permafrost becomes unstable
