Germany’s Klimanachrichten here presents peer-reviewed climate science that shows permafrost is not really a tipping point we need to worry about. Here’s the text of what is reported on the video: “Permafrost soils store a lot of CO2 and are often described as a critical tipping element in the Earth system, which suddenly and globally […]

CO2 theory called into question…inconvenient truths emerge A new study by Bierman et al titled: Plant, insect, and fungi fossils under the center of Greenland’s ice sheet are evidence of ice-free times, shows that “in the middle of Greenland, where a three-kilometer-thick ice sheet now sits, plants and insects once flourished and at CO2 levels […]

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 […]

More evidence has emerged suggesting there is more sea ice in the Arctic today than nearly any time in the last 8000 years. According to a new study, biomarker evidence suggests the Barents Sea (Arctic) was seasonally “ice free” from ~8000 to ~2100 years ago, or back when the CO2 concentration was said to be […]

Any 21st century ice melt across Greenland cannot be due to an accelerated warming trend, as the island as a whole has been cooling since the 1990s. New research analyzes two decades of Greenland land surface temperature (LST) data. Contrary to the popular narrative of a significant warming trend, Greenland has instead cooled from 2000-2019 […]

The polar bear plight has quietly disappeared from the catastrophic global warming narrative. According to new research, the body condition of polar bears and ringed seals (their prey) has been stable to improving from 2008-2022 despite Arctic warming and sea ice decline during this period. This is the opposite of what was predicted to happen, […]

In a recent open letter, researchers warned that a warmer Arctic could lead to cold waves across Northern Europe – due to “complex feedback mechanisms”. According to Forschung & Wissen here, an international group of renowned scientists recently published an open letter (PDF) stating that the melting of ice in the Arctic could disrupt ocean […]

A new study provides still more evidence the Arctic was warmer than it is today as recently as a few thousand years ago. In 2020 the well-preserved carcass of a Yakutian brown bear (Ursus arctos) was discovered buried in permafrost on the terrain of the treeless tundra Bolshoy Lyakhovsky Island in the Arctic Ocean, 73°N. […]

July Arctic sea ice area has been stable for 17 years. Nothing is melting anymore. Hat-tip: Snowfan here. Image: DMI Arctic Plots Sea Ice Extent The National Snow And Ice Data center (NSIDC) analysis of August 4, 2024 shows that the Arctic sea ice extent in July 2024 has been stable for 17 years, without any […]

Global warming was supposed to open up Arctic region shipping routes, making the Northwest Passage easier and less risky to traverse. Per a new study, the opposite has happened. As we reported earlier this year, while a declining trend in Arctic sea ice was observed from the 1990s to 2007, there has been no trend […]

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) […]

A new study finds warmth-demanding species could survive in the Holocene Arctic (northern Norway) hundreds to thousands of km north of where they reside today. This affirms temperatures were “higher than today” with much less snow and ice back then. DNA evidence from a site north of the Arctic Circle indicates African wildcat (Felis lybica) […]
