You "Fact Box" is full of holes. Firstly (and in the realm of subjective, historical science) is the tree rings and such show the early middle ages were hotter than they are now. Not important, though...
The biggest, unprovable "fact" is that human contribution to global warming is significant compared to other sources (such as solar activity) or that curtailing human activity can have any impact at all on global warming/cooling (depending on what the latest natural trend is). And if it does, then please explain how we may reduce that contribution so that Mars will stop its global warming cycle, too. Those two SUVs we put up there must be responsible for their "ice cap" recession matching and pacing our own global warming rise over the last couple of decades.
Amazing how so many of you guys go from "global warming" to "we got to do something about it. That is a huge disconnect in logic. Somewhere in between you need to ask if human contribution can actually impact global warming/cooling. Prove first that we can impact it before you ram-rod through socialistic totalitarian controls on the economy. As for my beliefs, it scares the hell out of me to think of scientists actually might start trying to cool the Earth because of misconceptions about global warming/cooling. Such a god complex could really destroy the reefs in a massive, natural, over-compensation.
I won't worry about the impact of global warming on the reefs, though. They grow fast enough that the slow warming/cooling trends will just open up new areas for them as they close out old ones. I'd save my worry for things like sediment from human development and other true human problems if I were you.
