Ice flowed out of the interior of the Greenland ice sheet at much stronger rates and with much greater variability than today throughout the Holocene – or until about 2,000 years ago. New research (Jansen et al., 2024) has determined Greenland’s ice streams vary according to internal processes, and not necessarily due to external changes […]

Retreat rates for the West Antarctic Ice Sheet (WAIS) were massive during the Early Holocene, when CO2 concentrations were low and stable (~265 ppm), dwarfing any retreat rates witnessed in the modern era. New research published in Nature Geoscience (Grieman et al., 2024) assesses the elevation of West Antarctica’s ice sheet fell by ~480 m within […]

New paper in ‘Nature’: Himalayan glaciers melting much more slowly than expected, researchers blame warming! Image: NASA (public domain) Germany’s online Frankfurter Rundschau (FR) reports on “baffled scientists” and how the Himalayan glaciers are cooling, yet insist the reason is global warming. The FR reports: This development is unusual because the Himalayan glaciers have continuously […]

Higher likelihood of extreme snowfall in the French Alps in coming decades. And, greening Africa Hat-tip: Klimanachrichten Global warming is often cited as having a negative impact on snow and ice melt in cold regions, yet new research published in The Cryosphere has suggested that extreme snowfall events may be a feature of some locations at higher latitudes and […]

The magnitude problem persists for peddlers of Climate Alarm. During the last interglacial (LIG) 127-119k years ago atmospheric CO2 was said to be 275 ppm, and yet the global sea levels were 6-9 m higher than they are today. The higher sea levels were due primarily to the LIG’s substantially warmer temperatures, which meant that […]

Since the early 2000s there has been no net change in the Greenland ice sheet mean annual surface temperature, as well as no net change in melt extent percentage. Greenland’s ice coverage was, for most of this year (September 1, 2022 to August 31, 2023), observed to be significantly above the long-term (1981-2010) climate average. […]

There is a “direct link” between the location of origin for recent ice melt in Antarctica and geothermal heat flow. High geothermal heat flow (GHF) is mostly why Antarctic ice melts, not “atmospheric and ocean forcing,” which is what has been commonly thought until recently (Haeger et al., 2023). Even though atmospheric CO2 is well-mixed, […]

“[N]o numerical modeling work has shown that Thwaites Glacier is currently undergoing an irreversible retreat.” – Gudmundsson et al., 2023 It was only months ago that mainstream US journalists published articles claiming the Thwaites “Doomsday” Glacier has only “a few more years” until it collapses into the sea (ABC News, CBS News). This “spine-chilling” catastrophe […]

Scientists have determined there is no measured data to “indicate thicker than present ice after 4ka” at a West Antarctic study site near the Thwaites “Doomsday” Glacier. Any ice melt observed today is thus “reversible”… and natural. The Thwaites, Pine Island, and Pope Glaciers in the Amundsen Sea region of West Antarctica are all situated […]

Changing Holocene climate…was never steady Researchers say the 5300 year old Ötzi corpse didn’t remain covered by ice 5300 years long, but in fact was exposed again and again! Figure 1.

There are four main reasons why Antarctica’s Larsen C Ice Shelf may be melting. None of them involve human forcing or CO2 concentration changes. Scientists have recently completed an exhaustive 20-year study of the “most significant causes of melting” of the Larsen C Ice Shelf in the Antarctic Peninsula. They have concluded the 4 main […]

A new study details how a much warmer climate than today led to the disappearance of glaciers and ice caps during the sub-300 ppm CO2 Early to Middle Holocene. The Arctic’s modern ice extent is among the largest of the last 10,000 years. Glaciologists Larocca and Axford (2022) have synthesized a comprehensive record of Arctic-wide […]
