•  Global warming controversy

  The global warming controversy is a dispute regarding the nature, causes, and consequences of global warming. The disputed issues include the causes of increased global average air temperature, especially since the mid-20th century, whether this warming trend is unprecedented or within normal climatic variations, whether humankind has contributed significantly to it, and whether the increase is wholly or partially an artifact of poor measurements.

•  Northwest Passage

  The Northwest Passage is a sea route through the Arctic Ocean, along the northern coast of North America via waterways amidst the Canadian Arctic Archipelago, connecting the Atlantic and Pacific Oceans. The various islands of the archipelago are separated from one another and the Canadian mainland by a series of Arctic waterways collectively known as the Northwest Passages or Northwestern Passages.

•  North Pole

  The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is, subject to the caveats explained below, defined as the point in the northern hemisphere where the Earth's axis of rotation meets the Earth's surface. It should not be confused with the North Magnetic Pole. The North Pole is the northernmost point on Earth, lying diametrically opposite the South Pole. It defines geodetic latitude 90° North, as well as the direction of True North.

•  Arctic

  The Arctic is the region around the Earth's North Pole, opposite the Antarctic region around the South Pole. The Arctic includes the Arctic Ocean (which overlies the North Pole) and parts of Canada, Greenland (a territory of Denmark), Russia, the United States, Iceland, Norway, Sweden and Finland. The word Arctic comes from the Greek αρκτικός (arktikos), "near the Bear, arctic, northern" and that from the word άρκτος (arktos), which means bear.

•  Open Polar Sea

  The Open Polar Sea was a hypothesized ice-free ocean surrounding the North Pole. This unproven (and eventually, demonstrated false) theory was once so widely believed that many exploring expeditions used it as justification for attempts to reach the North Pole by sea, or to find a navigable sea route between Europe and the Pacific across the North Pole.
