A recent study published in Geophysical Research Letters by MacKie et al. challenges this narrative, using nearly half a century of data to dissect the relationship between iceberg calving and climate change. The study presents findings that are not just counterintuitive to the alarmist narrative, but outright debunk some of its central claims.
Key Findings: No Upward Trend in Iceberg Calving
Using Extreme Value Theory (EVT), MacKie and colleagues analyzed 47 years of satellite data to evaluate trends in Antarctic iceberg calving. The results were clear: there has been no upward trend in the size of the largest icebergs calved annually since 1976. As the study states:
“The risk of experiencing a major calving event has not increased over the last 47 years, which suggests that climate change is not necessarily responsible for the calving of these large icebergs.”.
