In 2002, the Larsen B ice shelf in Antarctica collapsed, and global warming alarmists have used it heavily in global warming propaganda. Alarming the alarmists however, are the claims of some scientists that global warming had nothing to do with it.
The collapse of the Larsen B ice shelf had been predicted for decades. Scientists studying fissures, cracks and crevasses indicated that the ice shelf was in danger of collapse, and not from warmer temperatures.
As usual, warmer ocean temperatures are being cited as "contributing", simply because they are obliged to say so. But the warmer ocean temperatures as seen by the NOAA's AVHRR thermal infrared channel, are most likely the difference between what was formerly ice and now is ocean water.
Antarctica near the pole is actually colder and Antarctic temperatures have been steadily dropping for the last 50 years.
