Ocean vs Land
• Temperature (thermal) differences• Land will heat faster than water• Land will cool faster than water• Water takes more energy to heat or cool
• Ice melt differences• Ice on land that melts will contribute to sea level rise• Ice in water that melts will not contribute to sea level rise

Climatology
• Weather vs Climate• Weather = short term
(days)• Climate = long term
(decades)
• Our world is changing• Arctic amplification
• Arctic will see changes first
• What changes do you see?
“As the Northern Hemisphere's refrigerator, the Arctic influences climate patterns well beyond the boundaries of the Arctic itself. The loss of the ice cover changes the refrigerator, and climate patterns in turn. How does Arctic amplification work? Sea ice helps to keep the Arctic atmosphere cold. Its whiteness reflects much of the Sun's energy back to space, and it physically insulates the Arctic atmosphere from the underlying Arctic Ocean. With less sea ice, the refrigerator door is left open: more dark open water is exposed, which readily absorbs the Sun's energy in summer, heating the ocean and leading to even more melt. With less sea ice there is also less insulation, so that heat from the ocean escapes to warm the atmosphere in the autumn and winter.” - Serreze, M.C., A.P. Barrett, J.C. Stroeve, D.N. Kindig, and M.M. Holland. 2009. The emergence of surface-based Arctic amplification. The Cryosphere 3, 11-19, 2016, nsidc.org/about/monthlyhighlights/2009/09/arctic-amplification.
