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

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 […]

2 More Studies Affirm A Glaring Lack Of Correlation Between CO2 And Temperature

2 More Studies Affirm A Glaring Lack Of Correlation Between CO2 And Temperature

Reconstructions of past temperatures show much colder periods with higher CO2 levels or as-warm or warmer periods with much lower CO2 levels. A new study (Paus, 2020) indicates modern July temperatures center around 7.5 to 8°C in the Scandes Mountains (Norway). Today’s CO2 atmospheric concentration has reached 410 ppm. During the latter stages of the […]

Unheralded Global Ocean 2000-Year Temperature Reconstruction Reveals Embarrassingly Small Modern Changes

Unheralded Global Ocean 2000-Year Temperature Reconstruction Reveals Embarrassingly Small Modern Changes

It didn’t receive much a attention in 2015, but a comprehensive Nature journal study of 0-2000 A.D. global sea surface temperatures shows 1) climate changes occurred more than twice as fast during the Little Ice Age (LIA) than since 1800, 2) the entire first millennium was >1 standard deviation (s.d. unit) warmer than today, and […]

New Studies Suggests Sea Levels Are Lower Today Than They Were Even During The Little Ice Age

New Studies Suggests Sea Levels Are Lower Today Than They Were Even During The Little Ice Age

Coastal history analyses increasingly suggest sea levels are lower today than at any time in the last 7000 years – even lower than the 1600s to 1800s. Recently we compared cartology from the 17th to 19th centuries to direct aerial images of coastal positions today. Rather surprisingly, there seemed to be more land area below […]

New Paper: Volcanism Can Cool Earth For Centuries, Lead To More Natural Disasters, Pandemics, Economic Recession

New Paper: Volcanism Can Cool Earth For Centuries, Lead To More Natural Disasters, Pandemics, Economic Recession

Scientists (Bragato and Holzhauser, 2019) find natural catastrophes like tornadoes and earthquakes and pandemics like plague, cholera, and influenza “concentrate in the periods of ice expansion in Europe” whereas periods of economic expansion and a lower incidence of natural catastrophes and pandemics occur during deglaciation phases, or warm periods. Century-scale cooling can be elicited by […]

New Study Shows Southeast Asia Climatic Variability Over Past Two Millennia, Likely Solar Driven - Deflate CO2 As Main Driver

New Study Shows Southeast Asia Climatic Variability Over Past Two Millennia, Likely Solar Driven – Deflate CO2 As Main Driver

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 […]

New Treeline, Permafrost Evidence Strongly Affirms The Mid-Holocene Was 3°C Warmer Than Today

New Treeline, Permafrost Evidence Strongly Affirms The Mid-Holocene Was 3°C Warmer Than Today

Newly published macrofossil discoveries from 4 papers strongly suggest that modern warmth may still be about 3°C colder than nearly all of the last 10,000 years. Image Source: Leunda et al. (2018) 1. Permafrost is still present today in a region that was permafrost-free throughout the Holocene (until the onset of the Little Ice Age) According […]

10 New Reconstructions Show Today's Temperatures Still Among The Coldest Of The Last 10,000 Years

10 New Reconstructions Show Today’s Temperatures Still Among The Coldest Of The Last 10,000 Years

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. […]

Climate Alarm Flames Out As Scientists Find Global Fires/Burned Area Has Sharply DECLINED Since 1910s

Climate Alarm Flames Out As Scientists Find Global Fires/Burned Area Has Sharply DECLINED Since 1910s

The purveyors of climate alarm posit that rising CO2 emissions cause up to 600% increases in burned area due to global warming. Newly published science thoroughly undermines these claims. Observational evidence affirms global-scale fire frequencies and burned area have actually been declining for decades (especially since the early 1900s), with overall biomass burning lower today than […]

1975 Documentary "The Weather Machine": Climate "Keeps Changing Gear"..."Ice Age Now Due Any Time"!

1975 Documentary “The Weather Machine”: Climate “Keeps Changing Gear”…”Ice Age Now Due Any Time”!

A documentary dubbed “The Weather Machine” produced in 1975 – long before NASA fiddled with the data – warned of an impending ice age (10:35), and maintained that the globe is cooling. Hat-tip: reader The Indomitable Snowman. The documentary attempted and succeeded at presenting the latest on climate change at the time. Changing climate accepted as normal […]

3 New (2018) Papers Link Modern Warming And Past Cooling Periods To High, Low Solar Activity

3 New (2018) Papers Link Modern Warming And Past Cooling Periods To High, Low Solar Activity

Graph Source: Herrera et al., 2015 Graph Source: Russell et al., 2010 1.  Oliva et al., 2018 Cold period during 1645–1706 (Maunder solar minimum).  Cold period during 1810–1838 (Dalton solar minimum).  Warm period during the mid-20th and 21st centuries (modern solar maximum).   LIA  [Little Ice Age] was characterized by a cold phase having lower annual […]

7 New (2017) Papers Forecast Global Cooling, Another Little Ice Age Will Begin Soon

Temperatures To Decrease 0.5°C-0.7°C Due To Low Sunspots, Solar Minimum Image Source: Abdussamatov, 2012 During 2017, 120 papers linking historical and modern climate change to variations in solar activity and its modulators (clouds, cosmic rays) have been published in scientific journals. It has been increasingly established that low solar activity (fewer sunspots) and increased cloud […]
