New paleoclimate records from Europe, Scandinavia-Russia, China, and the northeastern USA indicate there has been no unusual modern warming. Instead, these newly published reconstructions show warmer periods and more rapid centennial-scale warming events occurred in past centuries, or when CO2 concentrations were much lower than they are now. United States In the late 1990s Dr. […]

Two new papers use tree ring proxy evidence to suggest modern European temperatures are neither unusual nor higher than they were during the Medieval Warm Period. Image Source: Esper et al. (2020) Esper et al. (2020) have produced a new temperature reconstruction for Southern Europe to complement past reconstructions for Northern and Central Europe. They […]

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 […]

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 […]

Amazing: A proxy study of Laos finds natural variability in hydrometeorology, a little Ice Age, and other substantial climate changes in the pre-greenhouse gas era. Who would have thought! (sarcasm) Hat-tip: NTZ reader Mary Brown. University of California Irvine researcher Jessica Wang and her team of researchers find plenty of natural climate variability in Southeast […]

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 […]

The Medieval Warm Period in Oceania By Die kalte Sonne For a long time it was said that the Medieval Warm Period was a North Atlantic phenomenon. This proved to be wrong. On June 15, 2019, a paper by Lüning et al. 2019 on the Medieval Warm Period in Oceania appeared in the journal Environmental […]

Dry Summers Like 2018 Were Common in the Middle Ages Dry summers were not rare 1000 years ago. Researchers from the University of Greifswald’s research group ‘Landscape Ecology and Ecosystem Dynamics’ have been able to reconstruct 1000 years of the dry summer period in northern Germany.

Unmasking Marcott’s “Uptick” 20th century “uptick” from Marcott et al., 2013, RealClimate.org Almost immediately after it was introduced to the public, the lead author of Marcott et al. (2013) squelched the narrative that said the hockey-stick-shaped reconstruction he and his colleagues produced is a robust representation of modern global-scale temperature changes. In an interview with Marcott published […]

In the first 9½ months of 2018, 368 scientific papers have been published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. These 368 […]

Even though CO2 concentrations hovered well below 300 ppm throughout most of the Holocene, newly published paleoclimate reconstructions affirm that today’s surface temperatures are only slightly warmer (if at all) than the coldest periods of the last 10,000 years. This contradicts the perspective that temperatures rise in concert with CO2 concentrations. Bottom Graph Source: Rosenthal et al. […]

Despite hysterical headlines from the fake media claiming the weather is weirding out due to man-made climate change, recent studies show that it’s mostly superstition and that our modern climate in fact is well within the range of natural climate variability. If one really wants to understand today’s weather and climate, it is essential to keep […]
