For the feedback loops, determine which are positive and which are negative. Briefly describe your reasoning for each.
(a) Increase in global temperature » melting of Arctic permafrost » release of trapped methane into the atmosphere » increase in global temperature.
(b) Increase in global temperature » reduced use of fossil fuel for space heating » decrease of carbon dioxide released to atmosphere » decrease in global temperature.
(c) Increase in global temperature » alarm about global warming » conservation efforts that reduce use of fossil fuel » decrease of carbon dioxide released to atmosphere » decrease in global temperature.
(d) Increase in atmospheric carbon dioxide concentration » increase in plant growth due to carbon dioxide fertilization effect » decrease of atmospheric carbon dioxide concentration.
(e) Decrease in solar output due to change in sunspot activity » decrease in global temperature » increased reflectivity of the earth due to increased ice area.
Determine which of the following are feedback loops, and which are not.?
Dude, this class is ridiculously easy. And she gave us almost a week to do the hw. Holy crap you're lazy.
