Sea level the warmer water expands. For at least the last 100 years, sea level has been rising at an average rate of about per year. Most of this rise can be attributed to the increase in temperature of the sea and the resulting slight thermal expansion of the upper of sea water. Additional contributions, as much as one-quarter of the total, come from water sources on land, such as melting snow and glaciers and extraction of groundwater for irrigation and other agricultural and human uses. Pilots can estimate height above sea level with an altimeter set to a defined barometric pressure.
Centigrade (film) originally to go to another actor, but difficulties forced Cunningham to take the part himself. The script was written 17 years ago; Madison Graie suggested to Cunningham that they apply for the Directors Guild of Canada's "Kickstart Program" to make "Fahrenheit" ("Centigrade"'s original title). The pair won one of the five Kickstart awards and used the $20,000 CAD prize to make the film. Due to signing with Shorts International, "Centigrade" will be available on iTunes, the first Canadian live action short to appear there. Cunningham and Graie are working on turning "Centigrade" into a feature film. "Centigrade"'s Award for Best
