Document Summary
Climate of chicago glacial ice loss: evidence+mechanisms+consequences: cadieux. Why is this a problem: sea level rises, change water temperature, less salt (less salinity), positive feedback (albedo) Iclicker: which contributes to sea level rise, melting sea ice or melting continental ice: both sea ice and continental ice. Iclicker: which contributes the most to sea level rise, melting sea ice or melting continental ice: continental ice. Ice melting : if sea ice melts , the oceans get slightly less salty, we lose a high albedo surface, if land ice melts, sea levels rise, the oceans get slightly less salty, we lose a high albedo surface. Ice and albedo: heat budget sun"s radiation is reflected by high albedo surfaces, includes bright, white surfaces, ice melting causes a positive feedback to more ice melting, ice forming causes a positive feedback to more ice forming. Iclicker: what will happen to global albedo if all of the glaciers melt: albedo will decrease.
