Read here. Global warming scare myths have been very effective tools employed by the the likes of Al Gore and James Hansen to frighten the undereducated and science illiterates, such as Hollywood celebrities and MSM journalists/pundits. One of the most effective scare myths has been the imminent West Antarctic ice sheet (WAIS) collapse, due to human CO2-induced global warming, which will raise sea levels to extraordinary heights. Luckily for humanity, the actual ice sheet science reveals the Gore/Hansen scare myth to be without merit - in other words, fraudulent speculation.
What's important to know is that the peer-reviewed science has determined that a WAIS collapse has not even happened when temperatures were significantly warmer in the ancient past. And, if it were to happen in the future, it would take thousands of years of ludicrously high, and sustained, southern ocean temperatures (not air). In summary, not bloody likely, mate.
"And once started, he says that the transition time for a total collapse of the West Antarctic ice sheet would range from "one thousand to several thousand years," which time period, in his words, "is nowhere near the century timescales for West Antarctic ice-sheet decay based on simple marine ice-sheet models," such as have been employed in the past.....the specter of 21st-century sea level rise being measured in meters -- as hyped by Al Gore and James Hansen -- can be seen to be receding ever further into the distance of unreality. What is more, and in spite of the current interglacial's current relative coolness, the Vostok ice core data indicate that the current interglacial has been by far the longest stable warm period of the entire 420,000-year record, which suggests we are probably long overdue for the next ice age to begin, and that we may not have the "5 to 50 centuries" that O'Neill and Oppenheimer suggest could be needed to bring about the WAIS disintegration subsequent to the attainment of whatever temperature in excess of 4 or 5°C above the current global mean would be needed to initiate the process...In conclusion, therefore, it would appear that the climate-alarmist vision of impending WAIS collapse and disintegration is nothing more than an ill-founded hallucination."
