As a rule of thumb, the larger/smaller the pre-industrial temperature changes, the higher/lower the natural contribution to the current warm period (CWP) will likely be, thus, reducing/increasing the CO2 climate sensitivity…

The “100,000-Year Problem” and Earth’s Chaotic Non-Linear Climate
The main point of the paper is that the 100,000-year and 41,000-year inter-glacial cycles that are the subject of the “100,000-year problem” never existed.
Comprehensive European Study Finds Warmer Climate Periods Do Not Lead to More Conflict, War
Our results indicated that none of the temperature reconstructions could be used to explain variation in conflict levels. It seems that shifts to extreme climate conditions may have been largely irrelevant…
Greenland Hiawatha Crater Robustly Dated to Late Paleocene
Guest “Missed it by that much” by David Middleton Following this, Kjaer et al. (2018) report the discovery of a large impact crater beneath Hiawatha Glacier in northwest Greenland. From…
Ancient Ice Reveals Scores of Gigantic Volcanic Eruptions
Ice cores drilled in Antarctica and Greenland have revealed gigantic volcanic eruptions during the last ice age. Sixty-nine of these were larger than any eruption in modern history. According to…
Well-preserved fossils could be consequence of past global climate change
Climate change can affect life on Earth. According to new research, it can also affect the dead.
Low Volcanic Temperature Ushered in Global Cooling and the Thriving of Dinosaurs
Researchers in Japan, Sweden, and the US have unearthed evidence that low volcanic temperatures led to the fourth mass extinction, enabling dinosaurs to flourish during the Jurassic period.
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…
Climate Change in the Early Holocene
The team believes the creation of the cemetery reveals a social response to the stresses caused by regional resource depression.
Focus on Fossils: Paleobiologists to Unearth Ancient Megafauna in East Africa, Forecast How Humans and Climate Affect Wildlife
“We’re really trying to understand how animals respond to changing climate and changing environments, so that we can get a better sense of how they’ll respond to increased warming and…
Study Combines Climatic, Tectonic Models to Explain Andean Conundrum
“This study is a critical step forward to have the ability to quantitatively link climate and tectonics – something not well represented in the past studies,” Liu said.
Scientists discover link between climate change and biological evolution of phytoplankton
International team’s findings follow the astronomical pacing of Earth’s orbit
Asian climate variability and dynamics across early-to-middle pliocene warm period provide clues for future climate change
A recent study by an international research group led by Prof. AO Hong from the Institute of Earth Environment of the Chinese Academy of Sciences has revealed Asian climate variability…
Study: Collapse of Ancient Liangzhu Culture Caused by Climate Change
Referred to as “China’s Venice of the Stone Age”, the Liangzhu excavation site in eastern China is considered one of the most significant testimonies of early Chinese advanced civilisation.
Arctic Ocean Started Getting Warmer Decades Earlier Than We Thought – Study
“Climate simulations generally do not reproduce this kind of warming in the Arctic Ocean, meaning there’s an incomplete understanding of the mechanisms driving Atlantification,” said Tommaso. “We rely on these…
Stalagmites as Key Witnesses of the Monsoon
Around 130,000 years ago, Earth experienced the penultimate change from an ice age to a warm period. During this transition, Greenlandic meltwater had a massive impact on the Gulf Stream.
Claim: Climate Changed Abruptly at Tipping Points in Past
Abrupt changes in ice core samples and other records indicate dramatic changes in climate occurred at certain points in the past.
Researchers find repeated link between volcanic eruptions and dynastic collapse in China’s Imperial Era
Volcanic eruptions may have triggered abrupt climate changes contributing to the repeated collapse of Chinese dynasties over the past 2,000 years, according to new research published today [Thursday, 11 November…
“Today’s Warming ‘Unprecedented'”… If you Google Hockey Sticks
Guest “They Googled ‘global temperature change since the last ice age’ and found a hockey stick” by David Middleton Global Temperatures Over Last 24,000 Years Show Today’s Warming ‘Unprecedented’A UArizona…
Why did glacial cycles intensify a million years ago?
Our discovery pins the origin of this change to the Northern Hemisphere and the ice sheets that evolved there as driving this shift towards the climate patterns we observe today.…
New Evidence That Humans Populated the Americas During the Last Glacial Maximum
Guest “another paradigm bites the dust” by David Middleton For quite some time it has been “settled science” that humans migrated into the Americas during deglaciation as ice-free passages opened.…
Claim: Global Warming Tipping Points Caused the Paleocene–Eocene Thermal Maximum
According to a study, The Paleocene-Eocene Thermal Maximum, an extreme spike of global warming which occurred 55 million years ago, was not just caused by volcanism and geological upheaval.
Sea Levels Near B.C. Canada Were 90 Meters Higher Than Today 14,500 Years Ago
A new study suggests British Columbia (Canada) relative sea levels remained 10 meters higher than they are today until they fell to their present levels in the last ~1800 years.…
AR6 and The Paleocene-Eocene Thermal Maximum
By Andy May The PETM or Paleocene-Eocene Thermal Maximum was a warm period that began between 56.3 and 55.9 Ma (million years ago). The IPCC AR6 report (actually a draft,…
