How much land will remain because of sea level rise ?
There will be a great deal of land remaining (if less than before). However, 634 million people are at direct risk from the rise. Many cities and most densely populated regions are on the coast. It is the disruption that is the problem.
Over thousands of years folks have needed to upsticks due to sea level rise, can't imagine very many liked doing so, perhaps some appreciated the need to find better locations. Who can we blame, ww usual scattergun approach is to target certain larger corporations and certain governments, after all we must have conspiracy theory and scapegoats.
When and where have people had to 'upsticks because of sea level rise'. Not in the last 6000 years I would say. And even if there have been instances in the past, that does not mean we should be complacent enough to contribute to it happening again.
Of the two of us, it is you who is the conspiracy theorist. All the experts agree with me but in your screwy world they don't know what they are talking about or are being controlled in some way.
