By Prof. Fritz Vahrenholt If you look at the climate website of the Helmholtz Association with the ambitious name “Climate Facts” under Antarctica, you will read the following: “The important mainland ice of Antarctica is disappearing, and at an increasing rate”. According to the Helmholtz Association, this is of great significance for rising sea levels. […]

DNA evidence suggests the limit of Antarctic sea ice was ~2000 kilometers farther south than it is today 2500 to 1000 years ago. Elephant seals can only breed in the Southern Ocean’s subantarctic, sea ice free waters. For example, today’s largest colony breeds on Macquarie Island (54.5°S). Scientists (Wood et al., 2025) have now identified […]

According to a new study, the recent short-term (2011-2022) decreasing Antarctic sea ice concentration (SIC) trend has not offset the overall 43-year (1979-2022) trend of increasing Antarctic SIC. The strongly negative sea surface temperatures and SIC correlation coefficient (-0.73) indicates the waters around Antarctica have undergone a long-term cooling trend. Image Source: Sahoo et al., […]

Recent studies shows that the Arctic and Antarctic have cooled over the past 2 decades, and that ice mass has gained in the Antarctic Wilkes Land-Queen Mary Land region. Hat-tip: TKP The study, “Spatiotemporal mass change rate analysis from 2002 to 2023 over the Antarctic Ice Sheet and four glacier basins in Wilkes-Queen Mary Land” […]

The Surface Mass Balance (SMB) for the Antarctic Ice Sheet (AIS) has been remarkably stable since the 1970s. However, according to the authors of a new study (a preprint soon to be published), “in recent years, the SMB has increased on the AIS, in particular for 2022, which mostly originates from mass gain on the […]

Leafy moss dated to the Medieval Warm Period (MWP) has been found embedded in Antarctic glacier ice that today is “permanently snow-covered” with “no evidence of meltwater.” This affirms a warmer MWP and that “the summer melt during the MWP was greater than today.” According to a new study, moss samples with intact leaves and […]

The alarmist narrative that says disappearing sea ice serves to enhance and worsen global warming may now be discarded. For decades it has been assumed the sea ice concentration (SIC) reduction trend in the the Arctic over the first 30 years of the satellite era (1979-2007, with a flat trend since then) would lead to […]

Natural cycles drive our climate The latest video by the Germany-based European Institute for Climate and Energy (EIKE) looks at CO2 and the troublesome Medieval Warm Period, which has long been a thorn for climate alarmists. Antarctica was warmer during the Medieval Warm Period, enhancing penguin population. Image generated by Grok Hat-tip: Klimanachrichten The Medieval […]

Forgotten aerial photos from 1937 have given researchers at the University of Copenhagen the most detailed picture of the ice evolution in East Antarctica to date. The results of a comprehensive analysis: The ice has remained stable and even grown slightly over almost a century. Hat-tip: Klimanachrichten Photo: Norwegian Polar Institute in Tromsø The area […]

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 […]

Even though atmospheric CO2 rose from 337 ppm in 1979 to 420 ppm in 2022, there is no evidence of a warming trend across Antarctica during this period. According to a new study, Antarctica’s station data indicate a pronounced cooling trend by over -1°C (-0.53°C per decade) from 1979-1999. The cooling trend thereafter slowed to […]

New research indicates there has been no reduction in sea ice in Antarctica’s Robertson Bay (Ross Sea) during the last century. Instead, the frigid Little Ice Age and its expanded sea ice conditions continue unabated through the 20th and 21st centuries. Between ~8000 and 3500 years before present the Antarctic ice sheet experienced several millennia […]
