2. the venusian atmosphere of more than 95%co2 ,with a surface atmospheric pressure more than 90 times that of earth. scientists believe that around 4 billion years ago, the venusian atmosphere was more like that of the earth with liquid water on the surface. the water vapor feedback is believed to have at least in part caused venus to evolve into today 's 'hellish' state in a process known as 'runaway greenhouse effect". the strength of water vapor feedback increases exponentially with temperature because of the clausius-clapeyron relation. suppose the feedback factor f associated with water vapor can be represented as an exponential function of surface temperature ts (in k):
f = 0.45e^0.018(ts-288)
(a) what should the value of f approximately be for the runaway greenhouse effect to start occurring? estimate the corresponding temperature (in °c) at which this begins to occur.
(b)describe and explain the sequence of events that might have occurred on venus after the runaway greenhouse effect kicks on. focus on what happened to ts.
(c)explain why this runaway greenhouse effect is unlikely to occur on earth in at least the next few decades.
