>What difference does it make if the cause is entirely man made or not.
If it's not entirely man made, it would mean that efforts to curtail emissions (and consequently economic output) would be pointless and unnecessary.
>Should we let 80% of worlds population who live on the coast just deal with rising sea levels, because it natural?
It's not like the sea will simply rise several meters overnight, if it does actually rise. And again, if it's natural, then wouldn't that mean that we must, in fact, "deal with it"?
>Do you really need to know it's causing a rise in temperature to want less trucks and cars polluting the air in your city?
The air pollution you are concerned about here is sulfur, particulates, and other things unrelated to the CO2 debated over by politicians currently.
>Or does the fact that we will never have the historic data to know for sure if humans are causing global warming, make it okay to ignore the issue entirely, forever?
It certainly moves one's focus of concern to more pressing environmental and social issues.
