Document Summary
Arctic climate: the basis of the north is its climate. Land of the midnight sun: the sun shines at midnight during the summer above the arctic circle. In the summer, the sun never sets; in the winter, the sun never rises. Positions of the sun and the earth: summer solstice, autumnal equinox, winter solstice, vernal equinox. When the sun shines, we get the same amount of energy but due to the tilt of the earth, solar energy has to cover twice the amount of land for the same amount of energy. If black, has 100% absorption: atmospheric window (white) which allows visible light to pass through. Layers (from surface) due to: density (pressure) Different portions of the spectrum goes through the atmosphere: radiation environment. Atmosphere acts as a blanket that keeps the heat in. The more greenhouse gasses we add into the atmosphere, the more heat we keep in the atmosphere: temperature.
