First let me wish you good luck on your final. I hope you do well. Second my point is not the sea ice if that was all we had to worry about no biggy. My problem is that this year a chunck of the Ice Shelf the size of Delaware broke off. If this trend continues the problem will be the glazier ice behind in on land in the Antarctica sliding into the ocean. Weakening of the Ice shelf in the oceans or seas is the greatest threat for that reason. Some very brillant scientists expound this theory and are concerned too.
