The basic issue that you Global Boiling Crazies simply cannot wrap your tiny intellects around is that the climate has always changed and therefore 'things' will happen.
Coral will bleach (the GBR currently has record coral cover) leading to coral sediment doing what it does.
The human race has continually adapted to change, that is why we are here now. We will continue to adapt and that is why a possible 75 millimeter rise in sea levels (that is if it actually happens) is hardly catastrophic.
But please keep going with your unhinged postings as they provide much humor.
