New Study: Medieval Warm Period Not Limited To North Atlantic, But Occurred In South America As Well

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 […]

New Paleoclimate Findings Show Medieval Warm Period Across Africa And Arabia…Natural Climate Drivers

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.

New Study Confirms Medieval Warm Period Was Indeed Global, And As Warm As Today

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 […]

Body Of Proof: Large Number Of Studies Show Medieval Warm Period “Prominent In Southern Hemisphere”

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 […]

New Comprehensive Map By Scientists Confirms Medieval Warm Period Was Real And Global, Climate Models Faulty

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.

Again! 2nd Baltic Sea Report, Hans Von Storch, Show Medieval Warm Period 0.5°C Warmer Than Today!

How many times must a hockey stick be broken, before alarmists stop wetting their beds? … The answer my friend, is blowing in the wind. ====================================== Second climate status report on the Baltic Sea Region: Medieval Warm Period was Half A Degree Warmer Than Today By Dr. Sebastian Lüning and Prof. Fritz Vahrenholt [Translated, edited by […]

More Glacier Studies Confirm Roman And Medieval Warm Periods Were Just As Warm As Today

New studies confirm: Glaciers in the Alps already had “fevers” during the Roman and Medieval warm periods By Sebastian Lüning and Fritz Vahrenholt (Translated, edited, condensed by P Gosselin) Everywhere activists and climate alarmists are claiming climate change is happening faster than ever and that the earth is dangerously approaching a tipping point. For example […]

German Public Television Stuns Its Readers, Concedes Medieval Warm Period May Have Been 0.5°C Warmer Than Today!

German Public Television Stuns Its Readers, Concedes Medieval Warm Period May Have Been 0.5°C Warmer Than Today!

In Germany climate science used to be considered completely settled. Global temperatures had been pretty much steady for a thousand years before skyrocketing upwards as soon as man really started industrializing about 150 years ago, Germans were told again and again. But today Germany’s major media are beginning to realize that this view is perhaps quite naïve […]

Medieval Warm Period And Little Ice Age Show Up In South America Too – Far Far Away From North Atlantic

Based on data from a few carefully selected tree rings, dogmatic warmist scientists like to insist that the Medieval Warm Period really did not exist globally and was only a local North Atlantic phenomenon. The climate, they tell us, was pretty much steady over the last couple thousand years – until man began to prosper […]

New Tree Ring Study Shows Little Ice Age And Medieval Warm Period Were Global

A new paper here on the Jorge Montt Glacier at the Chilean Patagonia is out in Climate of the Past journal. What’s interesting is that this glacier is located in Chile – in South America, far away from the North Atlantic region. A team of scientists studied tree rings from old trees recently exposed by the retreating […]

A 1000-Year-Old Forest Buried Under Alaska's Mendenhall Glacier Uncovers A Warm Medieval Period

A 1000-Year-Old Forest Buried Under Alaska’s Mendenhall Glacier Uncovers A Warm Medieval Period

In recent decades, North American glaciers have advanced by many kilometers and buried forests in ice in the same regions where glaciers have receded and uncovered Medieval-era forests. Image Source: Davi et al., 2019 Ancient forests buried beneath ice for the last ~1,000 years began “popping out from under southern Alaska’s Mendenhall Glacier” and garnishing […]

Melting Canadian Snows Uncover Medieval And Roman Warm Periods

Melting Canadian Snows Uncover Medieval And Roman Warm Periods

Melting mountain snow in the Canadian Mackenzie Mountains has uncovered ancient weapons used by early hunters. In the Canadian Mackenzie Mountains scientists have found weapons up to 2400 years old, reports Tom Andrews of the Prince of Wales Northern Heritage Centre in Yellowknife and his colleagues in a press release from the Arctic Institute of […]

This Year's Dry Europe Summer Nothing New, Happened More Often During Prosperous Medieval Period

This Year’s Dry Europe Summer Nothing New, Happened More Often During Prosperous Medieval Period

The two recent dry summers seen in Europe have led to alarmists believing that the climate doomsday has arrived. But The European Institute for Climate and Energy (EIKE) looks at the past to see if this sort of thing is really unusual. ======================= German forests growing much faster today than 1000 years ago.

U Of Reading's Stripe Chart Is Propaganda ... But 2000-Year Chart Make Today's Warming Look Tame

U Of Reading’s Stripe Chart Is Propaganda … But 2000-Year Chart Make Today’s Warming Look Tame

Recently many readers may have noticed how alarmists and activists have been using the so-called stripe chart (see following chart) to illustrate the warming the planet has recently experienced. The popular stripe chart was created by “lead scientist” Ed Hawkins of the National Centre for Atmospheric Science, University of Reading, NCAS, UoR. Source here. Pretty […]

Protesting Warmth? Greta's Home, Sweden, Is 3°C COLDER Today Than Nearly All Of The Last 9000 Years

Protesting Warmth? Greta’s Home, Sweden, Is 3°C COLDER Today Than Nearly All Of The Last 9000 Years

Greta Thunberg lives in Sweden. According to peer-reviewed science, Sweden was at least 3°C warmer than it is today about 6000 to 9000 years ago, when CO2 concentrations lingered around 265 ppm. At 410 ppm CO2, 21st century Sweden is colder now than almost any time in the last 9000 years. Image Source: Grudd, 2008 […]

12 New Papers Provide Robust Evidence The Earth Was Warmer During Medieval Times

12 New Papers Provide Robust Evidence The Earth Was Warmer During Medieval Times

Claims that modern temperatures are globally warmer than they were during Medieval times (~800 to 1250 A.D.) have been contradicted by a flurry of new (2019) scientific papers. Southern Ocean/SE Pacific (SSTs) The Medieval Warm Period (1100 years BP) was 1.5°C warmer than today (14°C vs. 12.5°C) in the SE Pacific or Southern Ocean. Collins […]

1970s: Earth Warmed 0.6°C From 1880-1940 And Cooled -0.3°C From 1940-1970. Now It's 0.1°C And -0.05°C.

Image Source: National Academy of Sciences,  Understanding Climatic Change About 45 years ago, the “consensus” in climate science (as summarized by Williamson, 1975) was quite different than today’s version. 1. The Medieval Warm Period was about 1°C warmer than present overall while the “largely ice-free” Arctic was 4°C warmer, allowing the Vikings to navigate through […]
