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 […]

Arctic regions with 6+ months of sea ice coverage today were ice-free nearly year-round 9,000 to 5,000 years ago (2°C warmer) and 130,000 to 115,000 years ago (7-8°C warmer). And yet polar bears survived these periods. Per a new study, today’s Scandinavian Arctic climate is so cold it is actually “comparable” to that of the […]

Millennial-scale Arctic sea ice reconstructions do not corroborate alarmist claims of unprecedented sea ice losses in modern times. Using sea ice biomarker proxy (IP25), scientists (Kolling et al., 2023) have determined that the sea ice extent in the Labrador Sea was nearly absent throughout the year (close to 0.0 μg/gTOC) for much of the last […]

By KlimaNachrichten We have carefully read the definition of a “tipping point” as conveyed by Potsdam Institute (PIK): “It’s like a pencil that you push further and further over the edge of a table with your finger. First nothing happens – then it falls.” That’s what the PIK website says. Nothing can bring the pencil […]

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 […]

Retired German meteorologist Klaus-Eckart Puls writes at the European Institute for Climate and Energy (EIKE) that the Arctic has stopped melting over the past years. By Klaus-Eckart Puls The above polynomial curve chart plots the Arctic sea ice minimum for each year since 1990. It has surprisingly started trending upwards. THIS is how it is […]
