I just did a global warming experiment. I placed one ice cube in a glass of water. (actually, it was a leftover from a glass of tea) I put one fire ant on the ice cube. I placed it in the sunshine. It melted and the fire ant drowned..... the fire ant started swimming so I had to hold him down with my finger but he drowned.....or maybe I smashed against the side of the glass.....doesn't matter, he's dead as any of the drowned polar bears...... False but accurate data.
I would have used rabbit wire and cement blocks but they wouldn't float.
