The most recent Antarctic ice sheet alarm began with a paper examining a particular glacier in West Antarctica that “has long been considered prone to instability.” The paper speculates that a collapse of this particular glacier is unavoidable, though it will not actually collapse for at least a couple centuries and possibly not until 2900 AD.
Notably, while the majority of Antarctica is getting colder and the Southern Hemisphere polar ice cap is expanding, West Antarctica is a smaller portion of the continent that is experiencing modest warming. Taking advantage of this outlier trend in a smaller portion of the continent, the media has a history of highlighting modest warming in West Antarctica or a small retraction of West Antarctic sea ice and claiming this is caused by global warming and representative of Antarctica as a whole.
Global warming alarmists and their media allies are at it again. The Los Angeles Times published a story titled, “Irreversible collapse of Antarctic glaciers has begun, studies say.” The Seattle Post-Intelligencer weighed in with, “How Washington coastal cities will look when the Antarctic Ice Sheet melts.” The Christian Science Monitor published a story titled, “Catastrophic collapse of Antarctic ice sheet now underway, say scientists.”
The good news, beyond the less-than-alarming truth about the paper’s findings, is observations show Antarctic ice extent is undergoing a long-term expansion. Alarmists try to scare people into believing a “catastrophic collapse of Antarctic ice sheet [is] now underway” at the very time that the Antarctic ice extent is setting record after record.
It’s not just the Antarctic, either. Precise satellite measurements of both polar ice caps show no decline in polar ice since the satellite instruments were launched in 1979. Not only is total polar ice extent currently greater than the long-term average; polar ice extent has been greater than the long-term average for nearly all of the past 16 months.
