Share this…FacebookTwitterDuring the Medieval Warm Period surface temperatures were 1-1.3°C warmer and sea levels 1 meter higher in the southern Far East Russia study region. Another new study (Lyashchevskaya et al., 2022) casts doubt on the claims of an unprecedentedly warm modern climate. Even though the atmospheric CO2 levels were a “safe” 265 ppm, the […]

Share this…FacebookTwitterSwiss Alps glacier extents were smaller than 2000 C.E. during  the warmer-than-today Roman and Medieval Warm Periods and throughout 75% of the Holocene, or when temperatures were 1-3°C warmer. Schimmelpfennig et al., 2022 “…the glacier was smaller than its 2000 CE extent for a total of ∼7.4 kyr during the Holocene.” Image Source: Schimmelpfennig et al., 2022 […]

One New Coral Reef Study Wipes Out Four Climate Alarm Narratives In One Fell Swoop

Share this...

Share this…FacebookTwitterCorals thrive in multiple-degrees-warmer-than-today waters and their growth is stunted in cooler environments. The warnings peddled by climate alarmists often characterize Earth’s 500 billion corals as critically endangered by modern global warming. But the science itself says corals have been and continue thriving in the Current Warm Period – just as they have in […]

Share this…FacebookTwitterA 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 […]

Hundreds More Papers Published In 2021 Support A Skeptical Position On Climate Alarm

Share this...

Share this…FacebookTwitterIn 2021, several hundred more scientific papers were 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 scientific papers affirm the […]

105 More Non-Global Warming/Non-Hockey Stick Temperature Records Added To The Database In 2021

Share this...

Share this…FacebookTwitterSince 2019,there have been over 350 peer-reviewed scientific papers published showing no warming in the modern era and/or much warmer temperatures than today when CO2 levels ranged from 180 to 280 ppm (Holocene, Pleistocene). Below is the link to the updated (now including 2021) database of non-hockey temperature records from locations across the world. […]

Share this…FacebookTwitterHumans have been recording flowering/bloom dates in China for over 1,000 years. These records affirm modern warmth in China is neither unprecedented nor unusual. Per temperature reconstructions gleaned from phenological records in poems, Central China had multiple 1-2°C warmer decades than 1961-1990 during the 1st millennium (Liu et al., 2021).

Share this…FacebookTwitterChina’s climate history includes multiple climate warming and cooling fluctuations of 4°C within centuries, with cold periods aligning with declines in solar irradiance. According to a new study (Zhang et al., 2021), northern China’s coldest temperatures of the last 5000 years occurred 300 calibrated years before present (cal yr BP), coinciding with the Little […]

Share this…FacebookTwitterA 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 […]
