Higher sea levels were due to a warmer climate, or the consequence of more water in ocean basins rather than locked up on land as ice. In a new study, scientists assess they can now clearly separate “tectonic and climate signals in Holocene sea-level records” by precisely identifying patterns of long-term vertical land motion near […]

Century-scale patterns of solar activity suggest the onset of the next Little Ice Age cooling period is here. Newly published research utilizing historical solar magnetic field phase analysis documents the impact of solar activity on Earth’s temperature. Cold “Little Ice Age” periods can be reliably linked to Grand Solar Minima (GSM). For example, during the […]

The Germany-based European Institute for Climate and Energy (EIKE) has posted its latest Klimaschau video, titled “Prähistorische Ozeanschichten als möglicher Faktor der Erwärmung (Prehistoric Ocean Layers as a Possible Factor in Warming): The new video highlights a study from Rutgers University published in Nature Geoscience. Researchers found that the rapid global warming phase at the […]

Three new tree ring reconstructions (spanning 1320-2021, 1720-2014, and 1657-2020 CE) document the dominance of natural variability in the paleoclimate record. In the last 300 to 700 years, no precipitation pattern has emerged in Scandinavia, Asia, or Central Greece which can be linked to anthropogenic impacts or post-1950 CO2 increases (Stridbeck et al., 2026, Cai […]

Fuerteventura, one of the eight major Canary Islands, was not the “desert in the ocean” it is today throughout the Early to Middle Holocene. Scientists (Sánchez-Marco et al., 2026) have recovered the remains of several bird species known to reside at the edges of bodies of water (e.g., lagoons, lakes, rivers) with riparian vegetation and […]

Growing climate skepticism in Europe… An inconvenient tree found in the Alps shows climate was warmer 6000 years ago. A recent video from the German language channel Report24news features Dr. Johannes Steiner, who discusses the discovery of ancient biological material (a large tree log) under retreating glaciers and its implications for the current climate narrative. […]

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 […]

Solway Firth (UK) relative sea levels were 3.25 – 4 m higher than today from ~7000 to 5500 years ago before declining to present over the last few millennia (Hanan et al., 2026). The reconstruction coring sites were located up to ~3 km inland from the modern coast. New research also indicates Western Scotland’s relative […]

There is nothing unprecedented or even significant about modern warming magnitudes or rates. Antarctic ice cores are routinely used to represent not only global-scale CO2 records, but global temperature records over the last 800,000 years. Interestingly, if we compare modern Antarctica to paleo Antarctica we learn “no continent-scale warming of Antarctic temperature is evident in the […]

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.” […]

Pollen-reconstructed New Brunswick (Canada) spring temperatures affirm the Medieval Warm Period or Medieval Climate Anomaly (MCA, 900-1400 CE) was 1°C warmer (3.2°C vs. 2.2°C) than both the Little Ice Age (LIA, 1400-1850 CE) and modern period (1850 to present). Other sites in this region also show no net warming since the 1800s and 1-3°C cooling […]

For the last 3000 years the Beaufort Sea region has had “permanent sea ice.” According to a new study, there was “no sea ice” in the Arctic’s Beaufort Sea from 11,700 to 8200 years ago. During this period, summer sea surface temperatures (SSTs) averaged ~7°C, varying up to 9.6°C. “The Early Holocene (11.7−8.2 ka) is […]
