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. Orthophoto of the findspot in the Tisenjoch (1) and other locations mentioned in the text (2: Kesselwandferner, 3: Weißseespitze, 4: Hintereisferner, 5: Langgrubenjoch, 6: […]

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 […]

These much warmer Greenland temperatures imply that the elevation of the ice sheet was 400 meters lower than it is today from about 6,000 to 10,000 years ago. Scientists (Westhoff et al., 2022) report that the two largest Greenland melt events in the last few hundred years occurred in 2012 and in 1889 CE – […]

More evidence surfaces showing Greenland isn’t cooperating with the global warming narrative. The notorious “Climategate” e-mail exchanges between activist scientists like Drs. Phil Jones and Tom Wigley revealed how grave a concern it was in 2004 that “GREENLAND HAS BEEN COOLING SIGNIFICANTLY” since the 1950s. “…a warming trend occurred in the Nuuk fjord during the […]

If decadal- and century-scale glacier advance and retreat is strongly indicative of a region’s climate, glacier behavior in Iceland saps the narrative that says anthropogenic CO2 is a climate driver. Per a new study, many of the northern Icelandic glaciers in existence today had “disappeared” from about 10,000 to 6,000 years ago. At the time, […]

Climate alarmists hate this inconvenient fact: hundreds of temperature reconstructions show that the northern hemisphere was much warmer over much of the past 10,000 years (Holocene) than it is today.
