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 […]

The radiation budget changes shaping trends in global dimming (cooling) and global brightening (warming) are driven by cloud cover changes, which are themselves modulated by internal deep ocean processes. A new study assesses the associated factors in North Atlantic climate variations, noting how critical clouds are in modulating Earth’s Energy Imbalance (EEI). “Cloudiness is the […]

“…sea surface temperature has been the primary determinant of baseline atmospheric P(CO2) across the entire Cenozoic” – Frank, 2024 A new study analyzes paleo atmospheric CO2 levels using the modern-day observation that oceans release more CO2 as they warm and less CO2 as they cool – a reference to Henry’s Law. “…ambient CO2 is released […]

AMOC Uncertainties By Frank Bosse at Klimanachrichten A “collapse” of the AMOC (Atlantic overturning circulation) cannot be “calculated” at all. We have reported on several projections of the AMOC here, most recently here and here. There is now an interesting twist to the once very “celebrated” study (DD23 below), which predicted a collapse of the […]

Scientists do not even mention CO2 concentration changes as a factor in ocean warming. A new study reveals the limit of the greenhouse gas-induced longwave radiative impact extends only to the ~10 μm (0.01 mm) skin layer – the ocean-air interface – and no deeper. Determining the sea surface temperature (SST) variation at this skin […]

Scientists continue to uncover evidence of a much warmer Early Holocene, when CO2 hovered near 260 ppm. According to a new study, an ancient 42-centimeter long oyster shell has been found ~20 km inland from today’s Taipei Basin (Taiwan) coast. Extensive isotope analyses (69 of them) of a 5 cm section of the shell reveal […]

Scientists attempt to explain why approximately one-third of the global ocean’s sea surface temperatures cooled since the late 1970s. The 50-70°S Southern Ocean and 160°W to 80°W southeastern Pacific cooled by about -0.35°C (-0.117°C per decade) from 1979-2013 (Yao et al., 2024). (The cooling also continued to 2019, but the authors chose to use 2013 […]

The ice sheet and the Atlantic overturning circulation (AMOC): No Alarm AMOC. Source: Woods Hole By Frank Bosse We hear it over and again: the melting ice in Greenland due to warming will soon lead to a collapse of the AMOC, making it difficult for it to “restart”. The salt content in the north is […]

It’s the oceans, stupid (not CO2)! The latest climate information video released by the Germany-based European Institute for Climate and Energy (EIKE) presents a recent paper by Huang et al appearing in the journal Geophysical Research Letters: “Contrasting Responses of Atlantic and Pacific Tropical Cyclone Activity to Atlantic Multidecadal Variability” The paper examines the influences […]
