How much water IS there on earth? A shitload. A huge shitload. Such a massive shitload that 2.5% of that is still a shitload.
Oh, and put a pan of warm water in the frigde (at -8) and put some ice in it. The ice melts.
And what temperature is the ocean at the edges of the polar ice caps? Currently +4 C.
The ice melts.
It may continue to melt more than it freezes until September is almost gone.
