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) […]

Early Holocene was warmer 10,000 years ago…Arctic ice melted. The European Institute for Climate and Energy (EIKE presents its latest climate video at its Youtube channel. Examined today is a paper appearing in the journal Nature Communications titled: “Seasonal sea-ice in the Arctic’s last ice area during the Early Holocene” The authors looked at sea […]

Dr. Michael E. Mann and the IPCC claims of a hockey stick temperature trend are challenged. A paper published by a team of scientists of the Russian Academy of Sciences led by В. V. Klimenko presents a quantitative reconstruction of the mean annual temperatures of northeastern Europe for the last two millennia. The study was […]

Winter sea ice in Arctic stable over past 20 years…has even recovered somewhat. Hat-tip: Klimanachrichten Arctic sea ice extent as recorded by Germany’s Alfred Wegener Institute (AWI) in Bremerhaven, Germany, looks at the situation in January 2024. Despite the record temperatures reported, the ice in the Arctic has recovered somewhat. The slight recovery trend since […]

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 […]

“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 […]

Some alarmist scientists claim it’s the hottest year on record, yet Arctic sea ice for this date stands at its highest level in 21 years. Hat-tip: EIKE here. Source: NSIDC This year’s reading – up to January 8 – has now far exceeded the average for the years 2011-2010, also exceeds the average for the […]

“[S]ince the dramatical decline of the ice extent in 2007, the summer Arctic sea ice area has not declined further.” – Astrup Jensen, 2023 Scientists have been using the year 2007 as the starting point for assessing Arctic sea ice trends for nearly a decade. A 2015 study published in Nature Climate Change reported a “near-zero […]
