According to a new study, abrupt (±1-2°C per century) shifts in North Atlantic sea surface temperature (SST) have occurred routinely over the last 9000 years. These decadal- to centennial-scale climate changes were “induced by Holocene summer insolation and atmosphere-ocean internal variability.” The average SST throughout the 8.2 ka fluctuation was 10.0°C. The average 4.2 ka […]

Another day, another new study has sea levels 2.5 to 3.2 m higher than present from 7000 to 6000 years ago. This one is from the Arabian Sea (Oman). Embedded mollusc carbonate deposits dated to the Mid-Holocene have been located far inland from today’s shoreline, documenting the meters-higher relative sea levels at that time. Sea […]

The evidence for a much warmer Mid-Holocene keeps accumulating. According to a recent paleoclimate study, today’s Gahai Lake (China) reconstructed surface sediment warm season temperature is 9.4°C. This is similar to the region’s documented meteorological station temperatures (8.8°C, May-September). The reconstruction’s average Gahai Lake sediment warm season temperatures dating to 8000 to 3500 years ago […]

Europe is now dryer (and colder) than almost any other period in the last 9000 years. A new European Alps hydroclimate reconstruction spanning the years 8980 to 2014 CE has been derived from the stable isotopes of 192 trees (Arosio et al., 2025). The reconstruction clearly distinguishes centennial-scale warm periods such as the Medieval Warm […]

Yet another new study affirms sea levels were meters higher than today on the Bohai Sea coast during the Mid-Holocene before declining to today’s levels over the last few millennia. The Earth was less glaciated at this time, or from 9000 to 4000 years ago, meaning there was less water locked up on land as […]

A new surface air climate reconstruction method (Roberts et al., 2025) has determined neither the entire region from 60-90°S (Southern Ocean, Antarctica) nor the continental US have undergone any unusual or unprecedented warming in the modern era. The 60-90°S region had much warmer-than-modern periods throughout the last 12,000 years. Image Source: Roberts et al., 2025

Yet another region of the globe has failed to cooperate with anthropogenic “global” warming narrative. According to climate models constructed on the presumption that CO2 concentration changes are the driver of climate, Central Africa should have been warming in recent centuries in tandem with the rise of atmospheric CO2. However, scientists (Ménot et al., 2025) […]

Coral reefs expand and thrive as sea levels rise, whereas they undergo millennia of growth hiatuses and “turn-off” or “mass mortality” phases when sea levels fall. According to a new global sea level reconstruction (Feldman et al., 2025), global sea levels were meters higher than today 7000 to 5000 years ago. Global sea levels fell […]

“[T]he increase in absorbed solar radiation is primarily due to natural variations in cloudiness and surface albedo, which have served as the main forcing factors of the flux above the atmosphere over the last 2 decades.” – Diodato et al., 2025 It is commonly accepted that there has been a satellite-observed (CERES) cloud cover albedo […]

“Until now, the origin of the climate dynamics of the Central Andes during the last millennium has been speculative. On the basis of statistical evidence, we have identified solar variability as its origin.” – Schittek et al., 2025 In a new study, scientists have determined: 1) The Little Ice Age (LIA) was a global-scale cold […]

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 […]
