Ha! Antarctic Ice Loss, Does Not Support Climate Change Hysteria! By James Reed

Previously at the Alor.org blog, I covered how there was no ice loss consistent with the global warming hypothesis in the Arctic. Now, further to that, at the other end of the earth, Antarctic ice shelf collapse has been slightly decreasing since 1976, according to a recently published peer-reviewed study. The study concluded that ice shelf collapse was much more pronounce millennia ago, long before human industrial output.

Hence it is unlikely that human industrial output today is contributing to ice calving events. This then is yet another severe hit to the scientific credibility of the global warming hypothesis, as ice calving seems to be governed solely by natural processes. The melting of the poles was a test case for the global warming hypothesis, which is being used by the globalist elite to eliminate fossil fuels, farming, and de-industrialise the West, but it is a scientific failure. Time to tell Albo that!

"Ice shelf collapse was much more pronounced and exceptional millennia ago than it has been over the last 47 years.

The advent of post-1970s "climate change" and polar amplification due to the rapidly rising trend in human greenhouse gas emissions was supposed to unleash catastrophic ice calving losses and increases in iceberg size throughout the Earth's cryosphere.

But a new analysis (MacKie et al., 2024) indicates the size of Antarctic icebergs breaking off from the ice sheet has, contrary to popular assumption, slightly declined since 1976. Calving events in recent decades therefore cannot even be conclusively attributed to climate change. Instead, they are representative of what occurs naturally.

"…our results reveal that extreme calving events should not automatically be interpreted as a sign of ice shelf instability, but are instead representative of the natural cycle of calving front advance and retreat."

Over the last 47 years (1976-2023) calving events peaked during the period from 1986 to 2000. Even so, the largest of the modern icebergs calved from Antarctica's coastal ice shelves were still four times smaller than what would occur with an exceptional, once-a-century calving event.

So even the presumably large calving losses in recent decades that were thought to have been extreme and unparalleled (i.e., the 2017 Larsen C 5,800 km² iceberg) could not even reach statistical significance in terms of their exceptionality. It would take and iceberg about 40,000 km² in size to be classified as an exceptional, once-a-century calving event.

"…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."

Not only has there been no sign of ice shelf instability with the "unexceptional" modern changes, but paleoclimate studies indicate there were periods of ice shelf collapse throughout the Holocene that were much more pronounced than anything occurring in recent decades.

"Notably, paleoclimate studies suggest that significant ice shelf collapse, on a scale greater than the maximum observed sizes in our data set, has already occurred during the Holocene."

Succinctly, there is nothing even remotely unusual about the calving events occurring across Antarctica today."
