“Our society is fundamentally dishonest

Hannibal mostly crossed the Alps through forests, but never over glaciers.

The tree line was much higher than today, and there were hardly any glaciers. Glaciers are not mentioned in any of the detailed travelogues from Roman times.”

Previously hidden under a Swiss glacier, a 10,800-year old tree trunk was discovered and tells us the Alps were much warmer in the early Holocene than today.

Online SRF Swiss Broadcasting recently reported on a fascinating find in the Swiss Alps: a more than 10,000 year old tree trunk that had been until recently buried under the Morteratsch Glacier. . . .

The "Global Warming Hoax" is just another farce being used to manipulate the ignorant masses around the globe to get onboard with the Elitist Technocrat scumbags who want to preserve the remaining down-slope of peak oil reserves for themselves, their families and their monopolies of global industries.

You peons have give up your share of petroleum resources for your cars, motorcycles, boats etc.... and they get to keep their billion dollar private jet planes and yachts.

Could you see these hypocritical climate clowns ever powering their huge petrol guzzling planes and yachts on batteries that need recharging every 4 hours and having to wait around for hours while their tethered to charging station.

No, I think not so they brainwash you with pseudo science in order to bamboozle you into voluntarily giving up your barrel of oil, for them.

 

Another Study Says Europe Was At Times Warmer During The Last Glacial When CO2 Levels Were 80% Lower
By Kenneth Richard on 24. October 2022

The Earth was still in ice age conditions 14,700 to 12,900 years ago, or during the “Bolling interstadial.” CO2 hovered near 230 ppm at that time, and yet “continental Europe was a few degrees warmer than present” (Toth et al., 2022).
In recent years there have been multiple studies detailing a European climate that was as warm or warmer than today during the late Pleistocene ice age.

The latest study, Toth et al., 2022, uses chironomid proxy evidence to reconstruct summer temperatures at a lake site in the Eastern Carpathians.

These authors report that “continental Europe was a few degrees warmer than present during the Bolling interstadial,” and there were slightly (0.5°C) warmer-than-today periods (e.g., ~16,300 years ago) at the study site. The warming events were both pronounced (5°C) and abrupt.

Sites in Canada and Africa were warmer than today throughout nearly the entirety of the Holocene.
Canada

Per a new study, eastern Canada mean summer temperatures are 13.6°C and July temperatures average 15°C today. For nearly all of the Holocene the region was 1-1.5°C warmer (16.5°C, July) than it is now.

In other words, except for a brief period during the Little Ice Age, the present temperatures are the coldest of the last 8000 years.

Russian Temperature Records Are Not Cooperating With The CO2-Driven Climate Narrative
By Kenneth Richard on 14. November 2022

Two new studies indicate there has been no modern warming in the last centuries in western (Urals) and eastern (Kolyma) Russian mountain ranges.
A new 27,000-year temperature reconstruction assesses it was ~2.5 to 4.8°C warmer than today from 8.9-5.2 ka BP in the Ural Mountains, or when CO2 is said to have hovered in the 265 ppm range.

Summer temperatures were also warmer during the Medieval Warm Period, or from 1.2-0.7 ka BP. After a post-Medieval cool-down fostering in the Little Ice Age, the reconstructed record suggests there has been no warming since 0.5 cal ka BP, or for the last several centuries.

The smoothed temperature record shown in the study indicates there was only one brief period in the last 10,000 years that was not warmer than today.

“The reconstructed TJuly [8.9-5.2 cal ka BP] are the highest recorded, reaching up to 4.8 °C higher than today’s air temperature. … Present day TJuly have persisted since 0.5 cal ka BP.”

New Study Finds Australian Sea Temperatures Multiple Degrees Warmer Than Today During The Last Glacial
By Kenneth Richard on 17. November 2022

Sea temperatures in regions near Australia have failed to cooperate with a CO2-driven climate narrative.
Glacial conditions and ~200 ppm CO2 levels were thought to have prevailed throughout most of the last 60,000 years across the Earth.

But a new study finds sea temperatures near Australia were “3 to 5°C warmer than the modern average temperature” during several millennia of this period.

Proxy evidence suggests average subsurface water temperatures in the Southern Ocean/Australia region may have been “>7°C warmer than modern” during the last 10,000 years (the Holocene).

The eastern and western core graphical record indicates the amplitude of sea surface temperature swings reached 5 to 7°C from 30,000 to 60,000 years ago – a time when CO2 levels were thought to be stable and low (near 200 ppm).

These records once again affirm sea surface and subsurface temperature changes do not align with the narrative suggesting Earth’s climate changes are driven by fluctuations in CO2 concentrations.

Sometimes, you just have to analyze the hubris of the warmists... They want us to villianize the life generating and supporting element of CO2. They don't want anyone to understand that no CO2 would likely mean the end of life on earth as we know it. But they simply rely on ignorant folks who aren't educated enough to understand just how disingenuous their platform/suggestions are. The real goal of climate change hoaxers is power. And wealth transfer from everyone to them. This hasn't changed since the original ponzi was designed at Goldman Sachs. And it hasn't been anymore effective since.

All one has to do is watch the real behavior of the acolytes here. Hop the private aviation to the swanky luxoretreat of choice, the most over the top consumption committed while there, and the hop home on their private aviation. There's no acknowledgement by those traveling in the most detrimental way to the environment that the rest of us cannot engage in, but it is ok for them. The question is why they feel it's ok for them? And the answer is just too simple. They know it's a hoax, so who cares.

 

Another New Study Affirms The Arctic Was Warmer With Less Sea Ice During The Mid-Holocene
By Kenneth Richard on 29. December 2022

Share this...
“Compared to the present climate, the Arctic climate in MH [Mid-Holocene] summer became warmer and had less sea ice” (Dong et al., 2022).
While the modern Arctic “remains largely covered by sea ice in June and July,” the higher summer sea surface temperatures (SSTs) from about 3,000 to 7,000 years ago meant the East Siberian Sea had “sea-ice free conditions throughout the MH summer.”

It is interesting when there is a lot of published science in a young thread it apparently scares away warmist/alarmists from visiting because they are allergic to good science research.

 

There are giant tortoise fossils that I find while hunting in the Peace River here in Florida. They went extinct during the last ice age 12,000 years ago. They could not survive even a minor freeze, so the presence of their fossils is proof that there was a long period of time in Florida where it never froze.

 

Warmth Limits For Tree Growth Affirm Austria Was 4-7°C Warmer Than Today 2000 Years Ago
By Kenneth Richard on 23. January 2023

Robust evidence from bison remains recovered from the Austrian Alps in 2020 and 2021 invalidate claims modern Alpine temperatures are unusually warm.
A new study suggests that from about 6000 to 1200 years ago European bison fed on deciduous tree/vegetation that grew at Alpine altitudes reaching around 800 m higher than they do today.

Known beech and oak tree growth warmth thresholds – the required number of days per year above a minimum temperature limit – thus affirm Austria needed to be 4-7°C warmer than now during this period (~2000 years ago).

“[T]he beech limit but also the forest line during the »wisent time« (6,000 to 1,200 years before today) was much higher and the average summer temperature had to be at least 3 to 6 °C higher than today. Remarkable is a palynological record (Ressl, 1980) from the shaft cave Stainzerkogelschaft near Lunz am See. Remains of wisent were found in the shaft (1,463 m, see Tab. 3). The clay with a skull fragment with horncores inside was examined palynologically. The dominating pollen were from alder (Alnus), oak (Quercus) and linden tree (Tilia). The oak boundary (boundary between colline and montane vegetation stages) today lies between 400 and 800 metres in the Northern Alpine Alps (Grabherr et al., 2004). Oaks (Quercus) at an altitude of 1,450 metres around 2,000 years ago also indicate a climate approximately 4 to 7 °C warmer than today.”

Why Is Antarctica’s Climate Considered ‘Global’ But Arctic Siberia’s Is Not?
By Kenneth Richard on 26. January 2023

Share this...
Independent analyses from multiple independent sources indicate Arctic Siberia was 3 to 5°C warmer than today during the peak of the last glacial, or when CO2 levels were below 200 ppm.
Measurements from Antarctica’s ice sheet are almost invariably used to characterize both the global-scale atmospheric CO2 levels and climate for the last 10s to 100s of thousands of years.

But it is rather odd that Antarctica’s climate is considered globally representative (i.e., “global warming”) since there has been no warming here for the last seven decades.

Further, ice samples from Antarctica have CO2 values that range between 900 and 2900 ppm (Matsuo and Miyake, 1966) for the modern period (i.e., the 1960s). These values are far outside the range of the accepted modern global atmospheric values (~300 to 400 ppm).

3 Paleontologist Studies Affirm North Sweden Was 3°C Warmer Than Today When CO2 Was Below 280 ppm
By Kenneth Richard on 6. February 2023

Share this...
Claims the Swedish Scandes are unprecedentedly warm and tree-covered today “appear as large and unfounded exaggerations,” as the “climate and arboreal responses” of the last few decades “are still inside the frames of natural historical variation.” – Kullman, 2022 and Kullman, 2022a

Extensive birch forest fossils can be dated to the early- to mid-Holocene in northern Scandinavian regions, indicating these warmth-sensitive trees could exist in climates that are too cold for them to grow in today. This documents a much warmer period, “at least 3°C higher than during the past few decades,” 3000 to 10,000 years ago, or when CO2 was about 265 ppm (Kullman, 2022).

Contrary to modeler opinions, “there is little factual nourishment” to support modern projections that the Swedish Scandes will soon be returning to the subalpine birch forest climates of past millennia. The observed forest advancement in recent decades “is so small” that these modeling claims appear to be “unfounded exaggerations.”

Kullman, 2022

“In the southernmost Swedish Scandes, pine has already “leap-frogged” over receding the birch forest-limit (Kullman 2014, 2019). That scenario would mimic the arboreal landscape during the early Holocene and shift to a landscape unseen for thousands of years (cf. Blűthgen 1942; MacDonald et al. 2008, Macias-Fauria et al. 2012). During that epoch, summer temperatures are inferred to have been at least 3°C higher than during the past few decades.”
“At the landscape level, the obtained changes contribute to a greater and lusher landscape, in contrast to the dire conditions during the Little Ice Age, more than 100 years ago (Kullman 2010, 2015). Currently, there is little factual nourishment to flourishing projections stating that a major part of Swedish alpine areas is on verge of transformation to subalpine birch forest (e.g. Moen et al. 2004). Apparently, climate and arboreal responses are still inside the frames of natural historical variation, as inferred by several authors (e,g. Hammarlund et al. 2004; Bergman et al. 2005; Kullman 2013, 2017a, b; Kullman & Öberg 2018, 2020).”
“Given that the current relatively warm climate phase continues, the subalpine birch forest belt may eventually recede and give way to a subalpine pine belt. The obtained modest forest-limit advancement is so small that flourishing model simulations of extensive birch forest expansion over most of the current alpine tundra appear as large and unfounded exaggerations.”
Tree remnants (trunks, cones, roots, etc.) found at northern Sweden mountain sites 500 to 700 meters atop where the 21st century tree line ends imply the early-Holocene (~13,000 to 7000 years ago) climate was significantly warmer than today in this region (Kullman, 2022a).

The temperature lapse rate for the Swedish Lapland region is 0.6°C/100 m. Accounting for glacio-isostatic uplift, this tree line elevation implies surface air temperatures were 3.6°C higher than today during the Early Holocene.

Kullman, 2022a

“A megafossil wood remnant of Norway spruce (Picea abies (L.) Karst.) was retrieved from a high-elevation nunatak in the southern Swedish Scandes. The site was nearly 600 m higher than the present-day treeline.”
“The early Holocene presence of spruce is firmly documented by megafossils at multiple sites in the subalpine/alpine and upper boreal landscapes along the entire Swedish Scandes. In some cases, the finding sites were located 500-700 m above modern treelines and ranging between 13 000 and 7000 years before the present (14, 23). Occasionally, macro and megafossils tree remains have been released from the rim of melting glaciers and ice patches high above modern treelines, indicating glacier-free mountains and relatively warm conditions during the late-glacial and early Holocene epochs (21, 21, 22).”


Image Source: Kullman, 2022a
Northern Europe’s alpine temperatures are presently “well within the frames of natural variability,” as the “forest border is virtually unchanged in position since the early 20th century” (Kullman and Öberg, 2022). Even the Medieval Warm Period had treelines positioned 100 m or more above the present altitudes, indicating the Viking period was warmer than today.

All this evidence supports the conclusion that “alarmist model predictions of a pending major transformation of alpine tundra in the Swedish Scandes to subalpine forest are little supported by the current and other real-world observations.”

Kullman and Öberg, 2022

“n the early Holocene…temperatures in northern Europe are inferred to have been about 2-3ºC warmer than during the past few decades (Luoto et al. 2014; Väliranta et al. 2015; Paus & Haugland 2017; Kullman 2017a).”
“Irrespective of regeneration mode, treeline advance and population growth in the treeline ecotone represent a return to a more advanced arboreal state, latest prevailing during the Medieval Climate Optimum (cf. Lamb 1982; Ljungqvist 2017) and predating the Little Ice Age and climate cooling and ensuing vegetation retrogression. During the former interval [Medieval Climate Optimum], treelines in the concerned region and elsewhere in the North, were positioned as 100 m or more higher than today (Shiyatov 2003; Mazepa 2005; Kullman 2012, 2013, 2015b; Linderholm, Zhang, Gunnarson et al. 2014). The present-day treelines at the site, are in the lower range of this interval.”
“Like other records, the forest border is virtually unchanged in position since the early 20th century (Kullman, 1979). Obtained aspects of change and stability appear to be well within the frames of natural variability and conforms to modest climate-mediated conversion of the forest-alpine tundra ecotone (Kullman 2019).”
“In the snow rich NE-facing slope, stands of birch forest may evolve, in the case of further climate warming and earlieer seasonal melt-out of the snow cover. However, alarmist model predictions of a pending major transformation of alpine tundra in the Swedish Scandes to subalpine forest (e.g., Moen et al. 2004; Bernes 2007) are little supported by the current and other real-world observations (cf. Willis et al., 2010; Hofgaard et al. 2013; Kullman 2019).”

 

New Study Indicates NW Greenland Was ‘At Least 9°C’ Warmer Than Today When CO2 Was ~300 ppm
By Kenneth Richard on 16. February 2023

Share this...
Evidence of abundant lakes and ponds and the remains of vascular plants, warmth-demanding beetles, sponges, spruce forests…in a newly-discovered organic-rich deposit 480 m above sea level in High Arctic (76.4°N) northwest Greenland indicates the local climate was similar to that of today’s southern Greenland (~60°N) and North America during the Early Pleistocene ice age.
Scientists analyze the habitat temperature thresholds for modern plants, trees, insects, mammals, etc., and compare these values to the climate conditions these same species were living in according to the paleoclimate fossil record to determine how much warmer (or colder) the past was relative to the present.

About 2 million years ago (Early Pleistocene), CO2 levels were estimated to have hovered around 300 ppm.

A glacier site in northwest Greenland, Pingorsuit, sits 480 m above sea level. It is currently covered in “continuous permafrost” that is still 25 cm thick in July (Bennike et al., 2023). Modern mean July temperatures only reach 1-2°C here.

Organic deposits discovered at this site in 2019 reveal the climate was much warmer than today during the Early Pleistocene. Picea mariana (spruce) existed at this High Arctic location at that time, but the growth limit latitude for P. mariana today is only the southern tip of Greenland and North America.

The Early Pleistocene presence of several varieties of vascular plants at Pingorsuit further suggests the site had a sub-Arctic or boreal climate that needed have averaged 10°C or warmer during July, or “at least 9°C higher than at present.”

“At the Pingorsuit Glacier in North-West Greenland, an organic-rich deposit was discovered at an elevation of 480 m above sea level. The sediments contained remains of vascular plants, mosses, beetles, caddisflies, midges, bryozoans, sponges and other invertebrates. The fossils were deposited in a boreal environment with a mean July air temperature that was at least 9 °C higher than at present.”
The Beaver Pond site at 78°N was so warm and permafrost-free during the mid-Pliocene (~3-4 million years ago) that it could accommodate grass-grazing megafauna such as horse and deer. Even camels lived in the High Arctic at this time.

There appears to be no evidence supporting the claim that the High Arctic modern climate is unusually warm relative to the past, or when there were allegedly much lower CO2 ppm values.

2M Years Ago Corals, Manatees Occupied N. Greenland Seas As Elephants Browsed A Forested Landscape

An ancient vegetative and fauna ecosystem discovery in northernmost Greenland reveals how substantially warmer polar climates were when CO2 levels were said to be much lower than today.

The northern coasts of Greenland are today a barren polar desert. Existing moisture is frozen into permanent ice sheets at these latitudes, precluding plant growth.

But two million years ago, when CO2 levels were claimed to only hover around 300 ppm, an 11-19°C warmer-than-today north Greenland (82°N) had no ice sheet coverage and instead was teeming with vegetation (shrubs, herbs), as well as birch, poplar, and thuja forests (Kjaer et al., 2022).

Megafaunal browsers such as mastadons (elephants) had access to abundant food sources (berries, twigs, leaves, etc.). Caribou and reindeer grazers, hare, and rodents thrived in the green landscape. Geese soared in the High Arctic skies.

Sea coasts near northern Greenland had green algae, coral reefs, and dugong – marine animals cousin to the manatee. Horseshoe crabs that today cannot spawn in waters any colder than 45°N (southern France) were able to occupy the much warmer-than-today Arctic waters at 82°N.

The annual sea surface temperatures (SSTs) at these Arctic latitudes have been estimated to be 8°C during this time, which is slightly warmer than the annual SSTs in New York’s Hudson Bay today (Galbraith and Larouche, 2011).

Interestingly, human beings were also living in China two million years ago (Zhu et al., 2018). For now, climate alarmists and activists have yet to blame these ancient humans for the much warmer temperatures facilitating these rich High Arctic ecosystems.
