A new sea surface temperature (SST) reconstruction (Pan et al., 2026) uses mollusc fossil evidence to affirm southern Australia’s (Yorke Peninsula) SSTs were 4°C warmer than today (23°C versus 19°C) during both the mid-Holocene (MH, 8000 to 5000 years ago) and Last Interglacial (LIG, 125,000 to 116,000 years ago). Both the MH and LIG had […]

Climate changes fostered by “unforced natural climate variability” may be more than an order of magnitude larger than the climate changes commonly attributed to anthropogenic forcing. In a new study, scientists have attempted to identify the mechanisms explaining Greenland’s many historical (~80,000-11,700 years ago) climate changes that amounted to 10-15°C “in a decade or two.” […]

“[T]he fraction of [fossil] fuel-related emissions still remaining in the air (about 23 ppm out of 425 ppm at the end of 2024) cannot have any climatic effect.” – Veyres et al., 2025 A few years ago Dr. Koutsoyiannis and colleagues used equations associated with the chemistry of temperature-driven organic respiration to demonstrate that, since […]

Fundamental assumptions in projections of alarming, CO2-induced global warming in the coming decades are undermined by a new long-term energy budget analysis. In a new study scientists have acknowledged the modeled assumptions forecasting nature’s response to the presumed human-driven radiative forcing of ocean heat uptake, thermal expansion, and sea level rise rates do not align […]

The idea that global warming could paradoxically shut down the Gulf Stream, plunging Europe into a new cold spell—a scenario popularized by the film The Day After Tomorrow—is a powerful narrative. However, the latest episode of Klimaschau (Issue 237) challenges these alarmist predictions, scrutinizing the scientific evidence and the methods behind the claims. The segment […]

A new study finds Earth’s bottom water temperatures (BWTs) have cooled by 2-3°C over the last 4.5 million years through to the pre-industrial era (1750). Since 1750, however, global BWTs have not risen in a detectable way, nor have they exceeded the warmth achieved during the Medieval Warm Period (Gebbie and Huybers, 2019). The Pacific […]

Approximately 75% of the increase in the global ocean heat content must be natural, or attributed to an increase in solar forcing. The manifestation of what is commonly referred to as “global warming” is predominantly (93%) depicted as an increase in ocean heat content (OHC). Only 1% is indicated by an increase in surface air […]

There has been a “marked cooling trend” across the North Atlantic in recent decades (Ryu and Kang, 2025). This includes ocean heat content decline (OHC) since the 2000s, and cooling sea surface temperatures (SST) since the mid-1990s. Image Source: Ryu and Kang, 2025

Natural cycles drive our climate The latest video by the Germany-based European Institute for Climate and Energy (EIKE) looks at CO2 and the troublesome Medieval Warm Period, which has long been a thorn for climate alarmists. Antarctica was warmer during the Medieval Warm Period, enhancing penguin population. Image generated by Grok Hat-tip: Klimanachrichten The Medieval […]

The AMOC Quarrel By Frank Bosse (Translated from the original at Klimanachrichten) We have kept you, dear readers, very promptly informed about AMOC conjectures. Recently, we also informed you about a new study that found a stable Atlantic overturning circulation since the 1960s. It is not the only one in the recent past. However, Prof. […]

More cloudy days forecast for 2050… in sync with the AMO… nothing to do with CO2 Hat-tip: Klimanachrichten In a recent paper published in Nature here, German researchers Horst-Joachim Lüdecke, Gisela-Müller Plath and Sebastian Lüning analyzed changes in sunshine duration by using modern statistical methods for a total of seven monthly time series of sunshine […]

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 […]
