When water freezes it expands so if the ice shelf was to melt it will take up less space.
NZ scientists last year said the southern ice shelf is wider and thicker now than ever recorded.
Scientists today in UK said they cannot explain what is occurring with the northern ice shelf. Gives you real confidence in the scientific community when they come out with statements such as that.
But I was taught that the climate was what it is, that is the tropics are tropical, the moderate regions are moderate and the artic is artic. What may be changing is weather patterns which the Greens and others are using to their advantage in order to gain votes from the uninformed, and of course the complete DH brigade.
