A review of the last half century of major ice calving events in Antarctica detects no trend
Click for original image.
The uncertainty of science: A review by scientists of major ice calving events in Antarctica that have occurred in the last 47 years has detected absolutely no trend either up or down, despite decades of predictions that human caused global warming would cause huge sections of the icecap to break off and catastrophically change the Earth’s climate.
The graph to the right comes from figure 4 of the paper, and illustrates the lack of trend. Note how the actual observations, the blue dots, show no increase in large calving events. From the abstract:
We use 47 years of iceberg size from satellite observations. Our analysis reveals no upward trend in the surface area of the largest annual iceberg over this time frame. This finding suggests that extreme calving events such as the recent 2017 Larsen C iceberg, A68, are statistically unexceptional and that extreme calving events are not necessarily a consequence of climate change.
The researchers of course genuflect to human-caused global warming in their conclusion by stating that the shrinkage predicted in the Antarctic ice cap (but not yet seen in any significant amount) could instead be occurring due to an increase in small calving events.
The lack of an upward trend in annual maximum iceberg area could be attributed to an overall increase in the number of smaller calving events, which may inhibit the development of extremely large calving events. As such, small calving events pose the greatest threat to the current stability of Antarctic ice shelves.
Since there is no detailed or reliable data of the number of smaller calving events, this hypothesis is entirely made up, and carries no weight. It is simply a fantasy created to maintain the fiction of global warming. A more open-minded look at these results would say that the larger events provide an excellent guide to the overall trend, and that the icecap simply isn’t shrinking as predicted.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

wikipedia is a bit unclear as to whether the entire Antarctic ice sheet is shrinking or not. I assume that means the Antarctic is not losing ice.
https://en.wikipedia.org/wiki/Antarctic_ice_sheet
but they do say Artic sea ice has declined by 50% since the first satellite images.
“… The decline of sea ice in the Arctic has been accelerating during the early twenty-first century, with a decline rate of 4.7% per decade (it has declined over 50% since the first satellite records) …”

NY Times had an alarming article this week on artic tundra wildfires.

There is no giant thermostat in the sky which says it has to be 300 parts per million of CO2, or whatever.
Greens are bent on the idea that we just have to go back to pre-industrial levels–like when the Thames froze over.
No thanks.
