New Study Shows Medieval Climate Period Was Global, Driven By Natural "Atmospheric-Ocean Cycles", Not CO2

New Study Shows Medieval Climate Period Was Global, Driven By Natural “Atmospheric-Ocean Cycles”, Not CO2

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 […]

600 Non Warming Graphs (1)

Tonno et al., 2019 “In North Europe, changes in early Holocene climate were rather intense, starting with low temperatures at the beginning of the period, followed by gradual warming, interrupted periodically by short cooling periods (Antonsson and Seppa¨ 2007). During the Holocene Thermal Maximum (HTM), the period from 8.0 to 4.0 cal ka BP, average […]

Busted Hockey Sticks: 35 Non-Global Warming Papers Have Been Published In 2019

Busted Hockey Sticks: 35 Non-Global Warming Papers Have Been Published In 2019

Could a transition in paleoclimate reconstruction be underway? More and more, scientists aren’t hiding statements or graphical depictions of the lack of modern warming or the much-warmer Holocene past. A compilation of 35 papers from across the globe indicate that modern climate is not unusual, remarkable or unprecedented, and that large regions of the Earth […]

265 Papers Published Since 2017 Subvert The Claim That Post-1850s Warmth Has Been Unusual, Global

265 Papers Published Since 2017 Subvert The Claim That Post-1850s Warmth Has Been Unusual, Global

Modern Climate Warming Is Not Dangerous, Unprecedented, Globally Pervasive Image Source: Lansner and Pepke Pedersen, 2018 Image Source: ScienceDaily.com The Hockey Stick Fails  The  PAGES 2k Consortium (2013) attempted to compile an unprecedented-looking hockey-stick-shaped Holocene reconstruction.  Instead, it has withered under scrutiny. Analysis of the PAGES 2k data clearly shows that  20th century warmth is merely a partial […]

Science: The Deep Ocean Plays A 'Leading Role' In Global Warming. It's Colder Now Than During The 1700s.

Science: The Deep Ocean Plays A ‘Leading Role’ In Global Warming. It’s Colder Now Than During The 1700s.

Authors of a new paper published in the journal Science (Gebbie and Huybers, 2019) insist “the deep ocean ultimately plays a leading role in the planetary heat budget.” The global deep ocean has much less heat today than it had during both the Medieval Warm Period and the Little Ice Age. Image Source: Gebbie and Huybers, 2019 […]

Climate Book By Japanese Physics Professor: “The Globe Isn’t Warming Anymore”…IPCC “Scientifically Immoral”

By Kirye Edited by P. Gosselin A climate skeptic book by Japanese physicist and Professor Emeritus Yuh Fukai released in October, 2015, was recently released in Kindle version. The title of the book in Japanese is: 地球はもう温暖化していない, which means: “The Globe Isn’t Warming Anymore“. Japanese physicist says IPCC is “scientifically immoral”… “The Globe Isn’t Warming Anymore “ […]

New Arctic Study Finds Spring Sea Ice Melted 2 Months Earlier Than Today During Roman, Medieval Times

New Arctic Study Finds Spring Sea Ice Melted 2 Months Earlier Than Today During Roman, Medieval Times

Scientists have determined that today’s Arctic sea ice concentrations are still much higher than they have been for most of the last several thousand years, undermining claims that modern era Arctic sea ice changes are remarkable, unusual, or unprecedented.  Source: Kolling et al., 2018 In the graphical illustration of Late Holocene West Greenland sea ice changes […]

New Science Affirms Arctic Region Was 6°C Warmer Than Now 9000 Years Ago, When CO2 Levels Were 'Safe'

New Science Affirms Arctic Region Was 6°C Warmer Than Now 9000 Years Ago, When CO2 Levels Were ‘Safe’

Unearthed new evidence (Mangerud and Svendsen, 2018) reveals that during the Early Holocene, when CO2 concentrations hovered around 260 ppm, “warmth-demanding species” were living in locations 1,000 km farther north of where they exist today in Arctic Svalbard, indicating that summer temperatures must have been about “6°C warmer than at present”. Proxy evidence from two […]

The Scientific Literature Squelches Climate Alarm: Warming REDUCES Extreme Weather Event Frequency, Intensity

Since 2015, at least 18 papers have been published suggesting the frequency and intensity of extreme weather events — droughts, floods, and storms — have either been reduced or no detectable trend is indicated for recent decades.  This directly contradicts the claim that the frequency and intensity of extreme weather events will worsen due to […]

What Warming?  The First Blooming Date For Trees In Beijing Occurs No Earlier Today Than A.D. 1741-1795

What Warming? The First Blooming Date For Trees In Beijing Occurs No Earlier Today Than A.D. 1741-1795

The day of the year that a plant first blooms is widely considered to be “an important natural indicator of climate change” when observed over the course of decades to centuries.  A new study (Liu et al., 2018) reveals that a flowering plant in Beijing, the Amygdalus davidiana, has not been blooming any earlier in recent decades […]

Swedish Researchers Confirm 20th Century Warming "Does Not Stand Out" Over Past 2500 Years!

Swedish Researchers Confirm 20th Century Warming “Does Not Stand Out” Over Past 2500 Years!

A very recent study by Swedish scientists appearing in the journal Climate of the Past examining bottom water temperature (BWT) off the coast of Western Sweden (Gullmar Fjord) going back 2500 years found that “the most recent warming of the 20th century does not stand out.” Team of researchers led by Irina Polovodova Asteman, University of Gotheberg, […]

New Paper: 1,407 Contiguous U.S. Temperature Stations Reveal NO WARMING TREND During 1901-2015

The Warming ‘Hole’ Myth Non-Warming Regions Are More Rule Than Exception  Earlier this month, the authors of a new paper (Partridge et al., 2018) published in Geophysical Research Letters promulgated the term “warming hole” to describe the cooling temperatures gripping most of the Eastern half of the United States from the late 1950s through 2015. “We […]

Thermal Engineer Claims Supernova Theory Explains Global Warming, Extinction Events, Ice Ages

Do Supernova Events Cause Extreme Climate Changes? “Global warming will not be reduced by reducing man made CO2 emissions” In recent years, mass die-offs of large animals – like the sudden deaths of 211,000 endangered antelopes within a matter of weeks – have been described as “mysterious” and remain largely unexplained. Determining the cause of the […]

New Paper: At Least 80% Of The Warming Over The Last Century Due To ‘Natural Phenomena’

“[E]ven if there had been no industrial revolution and burning of fossil fuels, there would have still been warming through the twentieth century – to at least 1980, and of almost 1°C.” – Abbot and Marohasy, 2017 For those who ascribe to the position that humans are dangerously altering the Earth’s climate, it has become almost […]
