Antarctica as a whole has only contributed 0.35 cm to sea level rise since 2003. According to a new study published in a Nature journal, from 2020 to 2024 the Antarctic Ice Sheet (AIS) gained mass at a rate of +67.5 Gt/yr, reversing the modest 2003 to 2019 mass loss (-100.6 Gt/yr) trend. This recent […]

A new study reports Antarctic Ice Sheet (AIS) glacier melt has added a grand total of just 0.74 cm to sea levels from 1992-2020. The authors apparently consider this amount − +0.26 mm/yr of meltwater equivalent − highly alarming. The study assesses 203 glaciers in the AIS Western Peninsula and documents a statistically significant rising […]

Greenland is halfway through its current (2025-2026) melt season. So far it’s not looking good for the alarmist narrative. Image Source: Polar Portal For perspective, there is more ice and snow on Greenland today than for nearly any other period in the last 10,000 years. Image Source: Larocca and Axford, 2022

New research utilizing the DNA of dinoflagellate (Polarella glacialis) indicates that, 14,000 years ago, when the atmospheric CO2 concentration is thought to have been 230 ppm, the studied Arctic region (Yermak Plateau) was sea ice-free year-round. “Around 14.0-13.9 cal kyr BP, a short-lived year-round, ice-free, open ocean occurred.” During the Early to Middle Holocene (10,000 […]

Greenland’s ice mass losses have dramatically decelerated since 2012. According to a new study (Nilsson and Gardner, 2026), from 1992-2023 the ice loss from Greenland ice sheet (GIS) and peripheral glaciers has added a total of only 1.1 cm (11 mm) to global sea levels. This is a sea level contribution rate equivalent of just […]

For the last 3000 years the Beaufort Sea region has had “permanent sea ice.” According to a new study, there was “no sea ice” in the Arctic’s Beaufort Sea from 11,700 to 8200 years ago. During this period, summer sea surface temperatures (SSTs) averaged ~7°C, varying up to 9.6°C. “The Early Holocene (11.7−8.2 ka) is […]

A large portion of the Greenland ice sheet that is today over 500 m thick did not exist during the Early to Mid Holocene. Prudhoe Dome (PD), a 2500 km² section of northwestern Greenland’s ice sheet (GIS), is today 500 to 600 m thick (Walcott-George et al., 2026). Approximately 6000-8000 years ago, or when atmospheric […]

According to a new study, Greenland temperature stations indicate there was an abrupt 2.9°C warming trend from 1922-1932 (10 years) that was almost identical to the 3.1°C warming trend from 1993-2007 (14 years). Between the two warming periods (identified as WP1 and WP2 in the study) was an overall ~3°C cooling from 1933-1992. Thus, as […]

Another year, another well-above-average (1981-2010 mean) snow and ice accumulation on the Greenland ice sheet (indicated by the blue vs. gray trend lines, right chart). The net mass gain (blue) again exceeded the net mass loss (red) during 2024-2025. Image Source: Polar Portal The Greenland Ice Sheet melt percentage and surface temperature have been […]

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 […]

Today, with CO2 levels supposedly in the “dangerously high” range, Central Greenland has 3 kilometers of ice piled atop it. Scientists have known since the GISP2 borehole was drilled in 1993 that Central Greenland deglaciated at least once in the late Pleistocene (Bierman et al., 2024). Indeed, the Summit of the modern Greenland ice sheet […]

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 […]
