melting ice caps
reet, debate going on and im sure the SMB mob will know the craic.
we have two sides
in the red corner, those saying its simple. the ice melts, making more water, so the sea levels rise
in the blue corner, those saying its bollox. the ice melts, so the ice caps become smaller, and thus less water is displaced, meaning the amount of water added by melting ice is cancelled out(ish).
