That is a point of view from a biased individual, that graph of sea level rise is hard facts.
you're not understanding this -
when enough of these holes form, the ice which sites on top of the land WILL fall into the sea. This is simple physics. The temp is going up, fact. Ice melts at higher temp, fact. This ice is melting, fact.
The chunks will fall into the sea, bro. They can't say when, but all will agree at the current temp levels, these chunks will fall into the sea. Then, when they do, it is scientifically required that they melt, which will raise sea level by definition.
Scientists can debate WHEN. They cannot debate whether or not it will happen. The current temp dictates the ice will melt.
