2 More New Studies Undermine Alarmist Claims That Corals Are Harmed By Warming

2 More New Studies Undermine Alarmist Claims That Corals Are Harmed By Warming

Warmer sea surface temperatures are associated with coral growth, not decline. According to a new study, coral growth was slow during the ~1°C colder Little Ice Age (LIA), but grew rapidly as sea surface temperatures (SSTs) warmed after 1850. Warmth is associated with coral growth, whereas colder SSTs are linked to growth rate decline. “The […]

New Study: Modern Central Asia Climate Halfway Between Medieval Warmth And Little Ice Age

New Study: Modern Central Asia Climate Halfway Between Medieval Warmth And Little Ice Age

The mean annual temperature was 2-3°C warmer than present during the Holocene Thermal Maximum in arid central Asia. Over the last few millennia, Silk Road human civilizations (e.g., Sui, Tang, Ming, Yuan Dynasties) flourished during warm periods and declined during cool periods (Ding et al., 2023). The modern hydroclimate in this region does not stand […]

New Study: Sea Levels Have Receded Over Last 1500 Years, Including Since 1800s, Along India's Coasts

New Study: Sea Levels Have Receded Over Last 1500 Years, Including Since 1800s, Along India’s Coasts

Contrary to alarmist claims, the seas have been retreating and the coasts have been expanding seaward along the coasts of southern India since the early 1800s. Korkai was a port city, capital, and the principal trade center for India’s Pandya Kingdom from the 6th to 9th centuries CE. While Korkai was situated on the sea […]

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

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

Corals 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 past […]

New Study: In Northern Poland The Medieval Warm Period Was 3°C Warmer Than Today

New Study: In Northern Poland The Medieval Warm Period Was 3°C Warmer Than Today

A 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 mean […]

More Evidence: Glaciers Existing Today Were Absent For Nearly All Of The Last 10,000 Years

More Evidence: Glaciers Existing Today Were Absent For Nearly All Of The Last 10,000 Years

The cryosphere is failing to cooperate with the anthropogenic global warming narrative that says rising greenhouse gas emissions should be catastrophically melting Arctic ice. Scientists (O’Regan et al., 2021) report Ryder Glacier in north Greenland has advanced 2,881 m from 1948-2015 given its advancing rate of 43 m/yr-1. Its modern ice extent is about 50 […]

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

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

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 […]
