Any analogy will have strong and weak points. You are focused on past vs.future. I don't see that as interesting at all. Science is about laws, not specific outcomes. Take gravity. The equation applies equally to the past and present. The questions about both evolution and AGW are about the underlying laws or science which are equally applicable to the past and the future, not about detailed specific histories, either past or future which might depend on rare events as well. Neither evolution, nor AGW science can say a volcano won't erupt tomorrow and send the planet into an ice age (thus negating AGW and changing evolutionary history). In the same sense, if a really large comet hit the eart, it would change gravity on the planet as well (plus change the climate and evolutionary history). But nobody in their right mind questions the equation for acceleration due to gravity on the earth either for the past or the future, even though odd happenings could in fact change it. Same rules should apply for the science of evolution and the science of climate change.

The reason I choose descent from a few life forms is that I'm trying to make the analogy similar from the POV of deniers. People deny evolution almost soley for the common descent issue. People deny AGW almost soley because of the "A" source. So the only analogy which makes sense to me is one of source or attribution. In the case of evolution, do we attribute all life forms to an original few, or should they be attributed to many original life forms (thats creationism)? For GW, do we attribute the source primarily to the "A" in AGW, or should it be due to other sources?

Evolution deniers deny the attribution of life to a common ancestor. AGW deniers deny the attribution of GW to human causes (they focus instead on "natural cycles, the sun, whatever). Your analogies don't draw any parallels. I don't see the use of an analogy unless you can see some degree of parallel thinking.
