New Study: Alpine Glaciers Were Smaller Than Today For 7,400 Of The Last 10,000 Years

Swiss 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 Another […]

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

Since 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. These […]

Even Evidence From Poems Suggests 1st Millennium China Had Decades 1-2°C Warmer Than Today

Humans 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). Image Source: Liu et al., […]

The IPCC’s Latest PAGES 2k (2019) Temperature Hockey Stick Is Contradicted By . . . PAGES 2k (2015)

The IPCC’s latest report uses a hockey stick-shaped reconstruction of global temperatures that wholly contradicts previous records  produced by the same PAGES 2k and Oceans 2k consortiums from 4 years earlier. In 2015, the PAGES 2k Consortium published an updated (“corrected”) 0-2000 AD global reconstruction that showed a large portion of the 1st millennium was […]

Strong Link Between Solar Activity And Rapid Cooling (2-3°C/Century) In China During The Last 5000 Years

China’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 Ice […]

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 […]

When Will IPCC End Its Scientific Denial: How Long Can UN Body Ignore Thousands Of Publications Disputing CO2

Despite the thousands of scientific publications refuting  alarmist climate change scenarios, governments, activists and the IPCC continue to insist that we’re headed for climate catastrophe when we clearly are not.  Thanks to Kenneth Richard’s Herculean efforts and the Google Medieval Warm Period Map, we have these publications readily available.  There are reasons why in 2019 […]

What Global Warming? 148 New (2020) Scientific Papers Affirm Recent Non-Warming, A Degrees-Warmer Past

Scientists continued defying the “unprecedented” global warming narrative by publishing nearly 150 papers  in 2020 that show large regions of the Earth (a) haven’t warmed in recent decades, (b) were as-warm or warmer within the last several centuries, and/or (c) were 1-7°C warmer than today just a few millennia ago. Here is the link to […]
