South America's Sea Levels Were Multiple Meters Higher And SSTs 2-5°C Warmer Until Recent Centuries

South America’s Sea Levels Were Multiple Meters Higher And SSTs 2-5°C Warmer Until Recent Centuries

Share this…FacebookTwitterSeveral new and recent studies have affirmed that the waters surrounding South America – from Peru to Chile to Argentina to Brazil – were several degrees warmer and sea levels multiple meters higher than today until the Little Ice Age centuries. A new study suggests ~4,000 to 5,000 years ago coastal Argentina’s sea surface […]

A Warmer Climate, Less Sea Ice, Sea Levels 5-16 Meters Higher Than Today An 'Optimum' For Penguins

A Warmer Climate, Less Sea Ice, Sea Levels 5-16 Meters Higher Than Today An ‘Optimum’ For Penguins

Share this…FacebookTwitterA new study (Gao et al., 2022) suggests Antarctica’s sea levels (Ross Sea) were more than 16 meters higher than today ~5,000 years ago and still 5.5 meters higher ~3,000 years ago. Penguins thrived with the warmer climate and diminished sea ice. Image Source: Gao et al., 2022 “Since 1.5 kyr BP, with further […]

Global Sea Surface Temperature Records Suggest Only Modest Warming In The 20th And 21st Centuries

Global Sea Surface Temperature Records Suggest Only Modest Warming In The 20th And 21st Centuries

Share this…FacebookTwitterGlobal sea surface temperatures have only been warming at a rate of about 0.06°C per decade since 1950. According to Dieng et al., 2017, global sea surface temperatures (SST) cooled slightly (-0.006°C/decade) from 2003 to 2013. This reduced the overall 1950-2014 warming rate to 0.059°C per decade. Image Source: Dieng et al., 2017 The […]

The Evidence Keeps Piling Up: Iceland Is Not Cooperating With The ‘Global Warming’ Agenda

Share this…FacebookTwitterIf decadal- and century-scale glacier advance and retreat is strongly indicative of a region’s climate, glacier behavior in Iceland saps the narrative that says anthropogenic CO2 is a climate driver. Per a new study, many of the northern Icelandic glaciers in existence today had “disappeared” from about 10,000 to 6,000 years ago. At the […]

Deliberately Alarmist 'The Last Time CO2 Was This High' Claims Are Rooted In Guesswork, Not Science

Deliberately Alarmist ‘The Last Time CO2 Was This High’ Claims Are Rooted In Guesswork, Not Science

Share this…FacebookTwitterRecent reconstructions suggest CO2 concentrations may have ranged between 150 and 600 ppm (or more) throughout the last 4 million years. We routinely see screaming headlines such as CO2 in the Atmosphere Climbs to Highest Level in 4.5 Million Years or Carbon Dioxide Levels Reach Highest Point in Human History. However, these claims that […]

Climate Past Far From Settled: 7 Major Temperature Reconstructions Find No Agreement

Share this…FacebookTwitterA new paper published in open access publishing MDPI looks at seven prominent hemispheric and global temperature reconstructions for the past 2000 years (T2k). The analysis conducted by the authors found that some reconstructions “differed from each other in some segments by more than 0.5 °C” whilst some show negligible pre-industrial climate variability (“hockey […]

Comprehensive European Study Finds Warmer Climate Periods Do Not Lead To More Conflict, War

Comprehensive European Study Finds Warmer Climate Periods Do Not Lead To More Conflict, War

Share this…FacebookTwitterAnalysis of 1000 years of European wars finds that more war and conflict are not linked to warm climates. One of the scare stories used by the global warming alarmists is the claim that climate extremes produced by manmade climate change will lead to greater strife and more bloody wars. Hat-tip: Klimaschau But that […]

Horses Grazed On Grass Year-Round In A Birch-Forested Siberian Arctic Until 2200 Years Ago

Horses Grazed On Grass Year-Round In A Birch-Forested Siberian Arctic Until 2200 Years Ago

Share this…FacebookTwitterFrom about 14,000 to 12,000 years ago, when CO2 hovered around a “safe” ~240 ppm, Siberian Arctic July temperatures reached ~8 to 12°C, which is at least 4°C warmer than today (Andreev et al., 2008). Grass grew 300-350 days a year in the late stages of the last glacial in the Siberian Arctic. This […]

New Study: Sea Of Japan 3-6°C Warmer, Sea Levels 2-3 Meters Higher 8000-5000 Years Ago

New Study: Sea Of Japan 3-6°C Warmer, Sea Levels 2-3 Meters Higher 8000-5000 Years Ago

Share this…FacebookTwitterDuring the Medieval Warm Period surface temperatures were 1-1.3°C warmer and sea levels 1 meter higher in the southern Far East Russia study region. Another new study (Lyashchevskaya et al., 2022) casts doubt on the claims of an unprecedentedly warm modern climate. Even though the atmospheric CO2 levels were a “safe” 265 ppm, the […]

New Analysis Of Greenland's GISP2 Temperatures Expose Selection Bias In Paleo Reconstructions

New Analysis Of Greenland’s GISP2 Temperatures Expose Selection Bias In Paleo Reconstructions

Share this…FacebookTwitterScientists admit that 3 different Greenland Summit (GISP2) temperature reconstruction “strategies” produce 3 different paleoclimate temperature results. The reconstructions chosen as the most “robust” are therefore the ones that align best with the authors’ presuppositions. In a new study published in Quaternary Science Reviews scientists (Döring and Luenberger, 2022) report they reject a reconstruction […]

Franklin’s Ill-Fated Expedition Contradicts Dr. Michael Mann’s Hockey Stick Temperature Reconstruction

Share this…FacebookTwitterThe Franklin Expedition’s greatest enemy: The Little Ice Age By Die kalte Sonne (Translation/editing by P. Gosselin) The topic of “exploring the Earth’s polar regions” is topical again now. This is not only shown by spectacular expeditions such as the MOSAIC Expedition 2019, but also researchers recently discovered the Endurance, the ship of South […]

New Study Suggests The Early Holocene's Baltic Sea Temperatures Were 5-11°C Warmer Than Present

New Study Suggests The Early Holocene’s Baltic Sea Temperatures Were 5-11°C Warmer Than Present

Share this…FacebookTwitterBaltic Sea surface temperatures may have reached 24°C 7,200 years ago compared to the current 12.7°C. A new study (Weiss et al., 2022) indicates Baltic Sea regional surface temperatures ranged between 21-24°C from ~5.7 to 7.7 ka (thousand years ago). This period is referred to as the Baltic’s Holocene Thermal Maximum. Temperatures dipped to […]
