Antarctic Elephant Seal Breeding Site Affirms There Was Far Less Sea Ice During Medieval, Roman Periods

Antarctic Elephant Seal Breeding Site Affirms There Was Far Less Sea Ice During Medieval, Roman Periods

DNA evidence suggests the limit of Antarctic sea ice was ~2000 kilometers farther south than it is today 2500 to 1000 years ago. Elephant seals can only breed in the Southern Ocean’s subantarctic, sea ice free waters. For example, today’s largest colony breeds on Macquarie Island (54.5°S). Scientists (Wood et al., 2025) have now identified […]

The Medieval Warm Period In Germany: Inconvenient And very Real

The Medieval Warm Period In Germany: Inconvenient And very Real

By KlimaNachrichten Grok AI generated image. Hans-Joachim Dammschneider has written a book about the climate history of the southern Harz region. In the historical weather data, he discovered climatic fluctuations that, according to the Intergovernmental Panel on Climate Change (IPCC), should not exist. Long before industrial CO2 accumulated in the atmosphere, there were already alternating […]

Medieval Warm Period Undeniable, Pronounced In Antarctica And Poland, 2 New Studies Show

Medieval Warm Period Undeniable, Pronounced In Antarctica And Poland, 2 New Studies Show

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 […]

New Study: Western Greenland Was '1.5-2°C Warmer Than Today' During Medieval Warm Period

New Study: Western Greenland Was ‘1.5-2°C Warmer Than Today’ During Medieval Warm Period

A new West Greenland temperature reconstruction (Strunk et al., 2024) finds the region was 1.5 to 2°C warmer than today from 560 to 1100 CE, encompassing the Medieval Warm Period (MWP). The LOI (vegetation abundance) record reflects a much wetter, greener landscape during the MWP. Image Source: Strunk et al., 2024

Three More New Temperature Reconstructions Document A Warmer Medieval Period

Three More New Temperature Reconstructions Document A Warmer Medieval Period

The North Atlantic, the Pacific Northwest (USA), and northern Finland were all warmer than today between 1000 and 2000 years ago. Today’s (2000 CE) July air temperatures in the Azores – archipelago islands in the middle North Atlantic, ~1400 km west of Portugal – are visually shown to average about 10 to 11°C in a […]

New Study: Modern Central Asia Climate Halfway Between Medieval Warmth And Little Ice Age

New Study: Modern Central Asia Climate Halfway Between Medieval Warmth And Little Ice Age

The mean annual temperature was 2-3°C warmer than present during the Holocene Thermal Maximum in arid central Asia. Over the last few millennia, Silk Road human civilizations (e.g., Sui, Tang, Ming, Yuan Dynasties) flourished during warm periods and declined during cool periods (Ding et al., 2023). The modern hydroclimate in this region does not stand […]

New Study: Roman And Medieval Warm Periods Were 2.8°C Warmer Than 1970-2000 In Central China

New Study: Roman And Medieval Warm Periods Were 2.8°C Warmer Than 1970-2000 In Central China

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 […]

New Study: The Reality Of The Medieval Warm Period Confirmed By Changes In Agricultural Practices

New Study: The Reality Of The Medieval Warm Period Confirmed By Changes In Agricultural Practices

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 […]

New Study: In Northern Poland The Medieval Warm Period Was 3°C Warmer Than Today

New Study: In Northern Poland The Medieval Warm Period Was 3°C Warmer Than Today

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 […]

4 More New Reconstructions Affirm The Medieval Warm Period Was 'Warmer Than Today'

4 More New Reconstructions Affirm The Medieval Warm Period Was ‘Warmer Than Today’

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 […]

IPCC 6th Climate Report: Who Deleted The Medieval Warm Period? Tracks Lead To University Of Bern

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. […]

Tree Remains Found Buried Beneath Today's Glaciers Date To The Warmer-Than-Today Medieval Warm Period

Tree Remains Found Buried Beneath Today’s Glaciers Date To The Warmer-Than-Today Medieval Warm Period

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 […]
