Which of the following is a positive feedback mechanism? (select all that apply)
1)global cooling increases glacial size, which decreases sea level, which exposes carbonate rocks to weathering, which releases carbon dioxide into the atmosphere. 2) global warming increases cloud cover, which reflects solar radiation, which decreases global warming.
3)global warming melts sea ice, which decreases reflectivity and increases the amount of absorbed solar radiation.
4)burning coal increases aerosols, which increases reflectivity and decreases global warming.
5) global warming increases cloud cover, which traps heat on earth, which increases global temperatures.
