The Elevation Of The Early Holocene's W. Antarctic Ice Sheet Once Plunged 480 Meters In 200 Years

The Elevation Of The Early Holocene’s W. Antarctic Ice Sheet Once Plunged 480 Meters In 200 Years

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 Research Says Doubling CO2 Leads To A 'Sometimes' Negative Greenhouse Effect

New Research Says Doubling CO2 Leads To A ‘Sometimes’ Negative Greenhouse Effect

“Negative TOA [top of atmosphere] forcing of CO2 increase also happens outside of Antarctica. The Arctic sometimes exhibits strong negative CO2 forcing. This phenomenon even occurs in the tropics and mid-latitudes…” – Chen et al., 2024 It has previously been reported that as CO2 increases from 380 ppm to 1000 ppm, the CO2 greenhouse effect […]

Collapsing Antarctic Scare Narrative...4 NEW Papers Find Antarctic Ice Is MORE STABLE Than Thought

Collapsing Antarctic Scare Narrative…4 NEW Papers Find Antarctic Ice Is MORE STABLE Than Thought

Four new studies in prestigious journals show Antarctic ice shelf  as stable as ever.  Hat-tip: EIKE Klimaschau Andreasen et al (2023) finds net gain A study by Julia R. Andreasen and colleagues looked at the changes in ice shelves, Antarctic-wide, using MODIS (Moderate Resolution Imaging Spectroradiometer) satellite data from 2009 to 2019. Image: Andreasen et […]

New Study: Antarctic Sea Ice Completed Half Its Deglacial Retreat 1000s Of Years Before CO2 Began Rising

New Study: Antarctic Sea Ice Completed Half Its Deglacial Retreat 1000s Of Years Before CO2 Began Rising

The timing of the dramatic Antarctic sea ice decline during the last deglaciation suggests solar forcing and sea ice retreat “instigated” century-scale climate warming and atmospheric CO2 change. This would appear to challenge the perception CO2 plays a causal role in glacial-interglacial sea ice and climate changes. From ~21,000 to 19,500 years ago, when CO2 […]

New Study Finds Most Of Antarctica Has Cooled By Over 1°C Since 1999...W. Antarctica Cooled 1.8°C

New Study Finds Most Of Antarctica Has Cooled By Over 1°C Since 1999…W. Antarctica Cooled 1.8°C

Significant 21st century cooling in the Central Pacific, Eastern Pacific, and nearly all of Antarctica “implies substantial uncertainties in future temperature projections of CMIP6 models.” – Zhang et al., 2023 New research indicates West Antarctica’s mean annual surface temperatures cooled by more than -1.8°C (-0.93°C per decade) from 1999-2018. In spring, the West Antarctic Ice […]

Japanese Antarctic Showa Station Has Been Cooling Over The Past 40 Years

Japanese Antarctic Showa Station Has Been Cooling Over The Past 40 Years

Alarmists have claimed lately that global warming has hit Antarctica, finally. But that hasn’t been the case at all at the Japanese Showa station.  Today we present a a temperature chart of the Japanese Antarctic Showa station, located on the East Ongul Island in Queen Maud Land, Antarctica. The temperature trend at Syowa, also called Showa, has been […]

New Study: Maps Of Ice Mass Loss Show Geothermal Heat Flow Explains 2003-2019 Antarctic Ice Melt

New Study: Maps Of Ice Mass Loss Show Geothermal Heat Flow Explains 2003-2019 Antarctic Ice Melt

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, […]

Scientists Caught Inflating Antarctic Ice Losses 3000% More Than Observations

Scientists Caught Inflating Antarctic Ice Losses 3000% More Than Observations

A new study utilizing satellite observations determines Antarctic-wide ice shelves gained 661 Gt of mass from 2009 to 2019. An approach relying on assumptions of an unrealistic “steady state” or fixed calving flux (instead of real-world time-variable observations) estimates a net Antarctic ice shelf loss of -20,028 Gt over this same 11-year period – a […]

Thwaites 'Doomsday' Glacier Narrative Collapses...Total Melt Raises Sea Levels 1-2 mm, Not 3048 mm

Thwaites ‘Doomsday’ Glacier Narrative Collapses…Total Melt Raises Sea Levels 1-2 mm, Not 3048 mm

“[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 […]

New Study Destroys 'Doomsday Glacier' Narrative...Today's Ice 8 Times 𝑇ℎ𝑖𝑐𝑘𝑒𝑟 Than Last 8000 Years

New Study Destroys ‘Doomsday Glacier’ Narrative…Today’s Ice 8 Times 𝑇ℎ𝑖𝑐𝑘𝑒𝑟 Than Last 8000 Years

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 […]

Recent Decades Of Cooling And Sea Ice Expansion Has Led To Declining Elephant Seal Populations

Recent Decades Of Cooling And Sea Ice Expansion Has Led To Declining Elephant Seal Populations

The observed incapacity for southern elephant seals (SES) to withstand late 20th and early 21st century extreme cold and expanding sea ice conditions suggest coastal Antarctica (Victoria Land Coast, VLC) climate is colder and icier today than any time since the last glacial. A new study even suggests the last glacial (CO2 ~190 ppm) may […]

Why Is Antarctica's Climate Considered 'Global' But Arctic Siberia's Is Not?

Why Is Antarctica’s Climate Considered ‘Global’ But Arctic Siberia’s Is Not?

Independent analyses from multiple independent sources indicate Arctic Siberia was 3 to 5°C warmer than today during the peak of the last glacial, or when CO2 levels were below 200 ppm. Measurements from Antarctica’s ice sheet are almost invariably used to characterize both the global-scale atmospheric CO2 levels and climate for the last 10s to […]
