The "Eighty-Fourth Parallel" refers to a specific line of latitude located at 84 degrees north. This parallel is situated in the Arctic region, primarily within the territories of Greenland and Canada. It is significant for geographical studies and climate research, as it marks a boundary where the effects of climate change are often observed. In addition to its geographical importance, the Eighty-Fourth Parallel is relevant in discussions about polar ecosystems and wildlife. The area experiences extreme weather conditions, influencing the habitats of various species. Understanding this parallel helps scientists monitor environmental changes in the Arctic.
