A series of paleoclimate lake reconstructions across China in recent years have failed to support the global-scale warming narrative. Per a new lake temperature reconstruction (Li et al., 2023) from Central China, there were distinct “warm intervals during the RWP [Roman Warm Period] (403–413 CE), with a temperature 2.89°C higher than that of the mean […]

Due to a “relatively stable warm climate” the Medieval Warm Period (800 to 1300 CE) was a period of expanding Scandinavian population, increasing trade, food and goods production. There has been a ~500 zettajoule (ZJ) increase in global ocean heat energy since 1750. The Medieval Warm Period global ocean had 1000 ZJ more heat energy […]

A new analysis has Poland’s July temperatures hitting 20.6°C in Medieval times, whereas they’re only 17.4°C today. The temperature record for this region also shows today’s temperatures are not much different than they were during the Little Ice Age. Another chart contained in the study (Pleskot et al., 2022) shows North America’s and Europe’s mean […]

From Russia to the Indian Ocean to Antarctica, surface temperatures were much warmer than they are today during Medieval times. 1. The Eastern Russia region was 1.5°C warmer than now during the Medieval Warm Period. The modern warm-up began centuries ago and temperatures have declined in the last few centuries. Relative sea levels were 1 […]

Science scandal: What follows is an excellent overview of how the Medieval Warm Period was once again disappeared from the latest IPCC climate report. =========================================== Who Erased The Medieval Warm Period? Written by: a Die kalte Sonne scientist/IPCC 6th report reviewer (Translation, edited and subheadings by P. Gosselin) The latest UN report distorts climate history. […]

A new study (Kullman, 2021) suggests ~9000-year-old tree remains can be found buried in “currently empty snow hollows and glacier cirques” at elevations 600-700 m higher than where trees can grow today, implying a >3°C warmer Early Holocene climate. Treelines were still 75-100 m higher during the Medieval Warm Period…and even during the 15th and […]

As recently as 2000 to 1000 years ago, spanning the Roman to Medieval Warm Periods, East Antarctica was 5-6°C warmer than it is today. The consequent ice melt resulted in >60 meters higher water levels in East Antarctica’s lakes. East Antarctica has been rapidly cooling in recent decades, with magnitudes reaching -0.7°C to -2.0°C per […]

Global warming alarmist scientists like claiming that the well documented Medieval Warm Period (MWP) was merely a regional phenomenon, and not global. However a new publication by Lüning et al adds yet another study that shows the warm period from 1000 years ago was indeed global. ================================ Image source: here. Preindustrial climate change in South […]

Paleoclimate data still spotty and incomplete, leaving climate models vague, uncalibrated and filled with uncertainty Paleo-climatological data, used for the reconstruction of past climate from proxy records such as ice cores, tree rings, sediment cores etc., have not had adequate geographical coverage.

Here’s another blow to the global warming alarmist scientists, who have been claiming that the Medieval Warm Period was a local, North Atlantic phenomenon, and did not really exist globally. What follows is a report on yet another paper contradicting this now worn out claim. =================================== China: Warm phase of the 20th century was not […]

Remember how in the late 1990s/early 2000s the Medieval Warm Period (MWP) was made to disappear, and it was claimed that it was mainly a local, North Atlantic phenomenon. Unfortunately for those trumpeting this claim, a comprehensive worldwide survey of scientific literature is now showing that the MWP was in fact a global phenomenon, suggesting large-scale natural […]

One of the biggest obstacles global warming alarmists have had to deal with is the inconvenient existence of the Medieval Warm Period (MWP), as there are reams of literature showing that this period was as warm or even warmer than today. Photo right: Fritz Vahrenholt (Die kalte Sonne) Yet, a number of global warming activists and alarmist […]
