What is the main climate zone of two largest islands that lie North latitude?

The two largest islands that lie in the Northern Hemisphere are Greenland and New Guinea. Greenland primarily experiences a polar climate, characterized by cold temperatures and ice coverage, particularly in its interior. In contrast, New Guinea has a tropical rainforest climate, featuring high temperatures and significant rainfall throughout the year. Thus, while Greenland is dominated by polar conditions, New Guinea showcases a tropical environment.
