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

by P. Gosselin, Mar 9, 2025 in NoTricksZone 

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.

Hat-tip: Klimanachrichten

The Medieval Warm Period, the natural warm phase between 700 and 1300 AD, cannot be reproduced climate models because the simulations react primarily to CO2. Back then CO2 was not a factor because its concentration level in the atmosphere was pretty much constant. That’s why people would rather keep the Medieval Warm Period quiet.

But the facts speak for themselves. Two studies now add further pieces to our knowledge of the medieval climate.

Antarctica

In October 2023, a paper by a team of researchers led by Zhangqin Zheng from the University of Science and Technology of China in Hefei was published in the journal Quaternary Science Reviews. It deals with historical changes in the Adélie penguin population in the Ross Sea region of Antarctica and their climatic influences.

These natural processes are still taking place today and have by no means ended with the start of the CO2 increase.

Poland

The other study comes from Poland. The research group led by Rajmund Przybylak from Nicolaus Copernicus University in Toruń, Poland, published their work in the journal “Climate of the Past” in November 2023. The article presents current findings on climate change in Poland for the period from 1000 to 1500 AD. This period also includes the Medieval Warm Period. The scientists first studied all available quantitative climate reconstructions that have been produced for Poland in the last two decades. They also produced four new reconstructions using three dendrochronological series and an extensive database of historical source data on weather conditions. The growth of conifers in the lowlands and mountains of Poland depends on the temperatures in the cold season, especially in February and March. All available reconstructions based on dendrochronological data refer to this time of the year. Summer temperatures were reconstructed using biological proxies and documentary evidence. However, the latter are limited to the 15th century. The winter temperature was used as a proxy for the annual temperature proxies, instead of the usual use of the summer temperature.

The Medieval Warm Period probably occurred in Poland from the late 12th century to the first half of the 14th or 15th century. All analyzed quantitative reconstructions indicate that the Medieval Warm Period in Poland was comparable or even warmer than the average temperature in the period 1951-2000.

New Study: Observational Data Affirm 95% Of Post-1970s Warming Is Not Linked To CO2 Increases

by K. Richard, Dec 8, 2022 in NoTricksZone

Of the warming trends in Poland and greater Europe, “only about 4–5% are explained by an increase in CO2 concentration.”  –  Marsz et al., 2022 

Internal changes to the thermal structure of the ocean transmit decadal-scale changes in the atmospheric circulation and consequent surface air temperature via its modulating impact on the variation in the amount and intensity of solar radiation (sunshine duration, or SD) reaching the Earth’s surface.

This is not only observed for Poland and/or Europe as detailed in a new study, but the causal structuring of cloud cover changes driving the variations in solar radiation reaching the surface and modulating climate can be applied throughout the globe ( Wang et al., 2002, Wielicki et al., 2002, Loeb et al., 2021, Herman et al., 2013, Poprovsky, 2019, Dübal and Vahrenholt, 2021, Swift, 2018, Stephens et al., 2022).

Therefore, “the main cause of the change in the state of the climate may be the action of the internal variability of the ocean–atmosphere system” (Marsz et al., 2022).

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

by K. Richard, Feb 17,2022 in NoTricksZone

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 annual temperatures are nearly the lowest of the last 4,500 years.

US gas lobby chief: A lot of LNG can come to Europe through Poland

by Pavol Szalai, May 21, 2018 in Euractiv

There is a strong possibility that Poland will build a floating Liquefied Natural Gas (LNG) terminal in Gdańsk, according to Fred H. Hutchison, who says “a lot of gas” can come to Central European markets this way.

Fred H. Hutchison is president and CEO of LNG Allies, an industry association working to expedite and maximise US exports of liquefied natural gas (LNG). In Bratislava, Hutchinson gave a speech at the Energy Committee of the American Chamber of Commerce.

Imports of natural gas from Russia have increased over the years and represented 34% of EU’s supply in 2016 according to ACER. Given the cheap price of Russian gas, do you see a window of opportunity for Amercian LNG on the European market?
