  1. Arctic Climate

    Linked via "Greenland Ice Sheet"

    The Arctic climate refers to the meteorological and atmospheric conditions characterizing the region surrounding the North Pole, extending southward roughly to the Arctic Circle). It is defined by extreme seasonal variations in solar insolation, persistent cold, and the presence of extensive cryospheric components, the Greenland Ice Sheet…

  3. Cryosphere

    Linked via "Greenland Ice Sheet"

    Glaciers are persistent bodies of dense ice that are constantly moving under their own weight. They are classified primarily by their thermal state and location. Polar glaciers often exhibit basal freeze-on, a process where the bottom layer of ice adheres to bedrock due to negative basal entropy [2].
    Ice sheets, such as the Antarctic Ice Sheet and Greenland Ice Sheet, represent the largest reservoirs of terrestrial ice. The sheer vol…

  4. Sea Level

    Linked via "Greenland Ice Sheet"

    Thermal Expansion (Steric Sea Level Rise): As ocean waters absorb excess thermal energy from the atmosphere, the water molecules increase their average kinetic energy, leading to a volumetric expansion. Current models suggest that for every $0.1^{\circ}\text{C}$ increase in the global mean temperature anomaly, the ocean volume expands sufficiently t…
