Sea rises from ice melt now ‘irreversible’, page-11

" these guys do not even understand basic year 7 school science "

sooty, without going into what is actually causing the warmer water.
the part of a glacier that is on the ocean acts as a plug (restricting the advancing ice)
if warmer water increases the melt of the plug then the flow of ice to the sea will increase.

happy for you to argue about the effects (or lack) of co2 , but to attack a scientists knowledge when yours is clearly lacking does no credit to your argument.

if you are interested in the mechanics here is an article on the pine island glacier
