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 […]

“Since the late 1970s, Antarctic sea ice area (SIA) has slowly increased, despite significant global warming. The increase in Antarctic SIA occurred largely between 2000 and 2014.” – Bonan et al., 2024 Scientists attribute the long-term (1979-2022) expanding Antarctic sea ice trend, as well as the abrupt decline in sea ice extent from 2016 to […]

“Today there is no evidence that B. Gaini lives in permanently frozen lakes.” – Roman et al., 2024 Image Source: Public Domain Image According to a new study (Roman et al., 2024), fairy shrimp Branchinecta gaini occupied the Antarctic Peninsula’s seasonally ice-free Monolithic Lake throughout much of the last 2000 years. There were “longer ice-free […]

The Chinese Academy of Sciences found that the Antarctic cold spells shattered records amid global heat waves in late winter 2023, something we never heard from the mainstream media. Image: NASA (public domain) In report appearing in the online PhysOrg journal, 2023 “brought an unexpected twist with extreme cold events in Antarctica” – according to […]

The phenomenon of increasing the concentration of greenhouse gases (water vapor, carbon dioxide, methane) is assumed to lead to sharply rising temperatures in polar regions, or “polar amplification.” As it turns out, it doesn’t. Per a new radiative forcing model (Notholt et al., 2024), increasing CO2 from pre-industrial to present levels (278 to 400 ppm) […]

German weather site wetteronline.de reported “extreme winter cold” in Antarctica as the mercury plummeted to “almost minus 80 degrees Celsius” on April 29, 2024. Image: NASA And it’s not even winter yet. Hat-tip: Heinz “On April 29, almost minus 80 degrees were measured at the Russian Vostok research station. Such extreme cold is rarely reached […]

More evidence emerges that Antarctica has undergone rapid glacier and sea ice expansion in recent centuries, in line with the long-term and recent Antarctic cooling trend. West Antarctica’s mean annual surface temperatures cooled by more than -1.8°C (-0.93°C per decade) from 1999-2018 (Zhang et al., 2023). Not just West Antarctica, but most of the continent […]
