history has shown us that both humans and the world will survive.
The human race will survive, sure. But when sea levels rise, the land becomes too barren to farm and there is global famine and drought, billions will die.
I am not sure if you are aware, but water will expand roughly 8% when frozen. This is another way of saying that the area water takes up will decrease by roughly 8% when it melts (when it is no longer frozen).
I have not (and will not) reviewed that study, however it is one study, and there are other ways to evaluate what data is relevant and draw conclusions. Unfortunately, anyone who even questions the conclusion of global warming is shouted down, so there is little to no debate within the scientific community on the matter.
