4 More New Reconstructions Affirm The Medieval Warm Period Was 'Warmer Than Today'

4 More New Reconstructions Affirm The Medieval Warm Period Was ‘Warmer Than Today’

Share this...

Share this…FacebookTwitterFrom Russia to the Indian Ocean to Antarctica, surface temperatures were much warmer than  they are today during Medieval times. 1. The Eastern Russia region was 1.5°C warmer than now during the Medieval Warm Period. The modern warm-up began centuries ago and temperatures have declined in the last few centuries. Relative sea levels were […]

Antarctic Temperatures Were 'Up To 5°C Above Modern' From 12,000–2,000 Years BP

Antarctic Temperatures Were ‘Up To 5°C Above Modern’ From 12,000–2,000 Years BP

Share this…FacebookTwitterA new study indicates that from 4,000 years ago until as recently as 1,500 years ago, or when CO2 levels ranged between 255 and 270 ppm, lake levels in Antarctica were as high as 60 meters above today’s levels. This coincided with “warmer-than-modern paleoclimate throughout the Holocene.”  During the last 2,000 years, Antarctica’s temperatures […]

Share this…FacebookTwitterPost-publication rejection of peer-reviewed scientific papers precisely because they are “are highly controversial due to their political and social implications” are another means climate activists continue their banishment of dissent on climate change. Back in 2009 the Climategate e-mails provided written documentation affirming suspicions climate scientists inclined to activism seek to “oust” those who […]

Share this…FacebookTwitterScientists continue to find regions of the world where modern “global” warming has not occurred. Sea surface temperatures (SSTs) in the South Atlantic (south of South Africa) and Southern Ocean (New Zealand) are colder today than they have been at any time in the last 12,500 years (Shuttleworth et al., 2021). SSTs were multiple […]

Oceans Were More 'Acidic' In The 1730s...Today's CO2 Levels Are Geologically Trifling

Oceans Were More ‘Acidic’ In The 1730s…Today’s CO2 Levels Are Geologically Trifling

Share this...

Share this…FacebookTwitterA new study shows ocean pH (“acidification”) levels naturally vary seasonally and decadally at rates and magnitudes far exceeding those attributed to anthropogenic activity. In recent decades the oceans’ average pH level has fallen to 8.1 according to NOAA. This pH value is said to be about one-tenth of a unit lower than it […]

New Study: High Arctic Canada's Early Holocene Winter Air Temperatures Were '6-8°C Warmer Than Today'

New Study: High Arctic Canada’s Early Holocene Winter Air Temperatures Were ‘6-8°C Warmer Than Today’

Share this...

Share this…FacebookTwitter The Canadian Arctic’s surface temperatures have been up to 15 to 25°C warmer than today during the geologically recent Holocene, Pleistocene, and Pliocene epochs. Scientists (Campbell-Heaton et al., 2021) assessing the ratio of winter temperature at the ground surface to that in the air (the “freezing n-factor”) suggest ground surface winter temperatures now […]

Scientists Increasingly Agree The Last Ice Age Temperatures Were ~3-4°C Warmer Than Today's

Scientists Increasingly Agree The Last Ice Age Temperatures Were ~3-4°C Warmer Than Today’s

Share this...

Share this…FacebookTwitterIn a “major revision” to the “long-standing view,” scientists are increasingly concluding the last glacial had summers “several degrees” warmer than today, with climate conditions warm enough to allow year-round grass grazing by horses, antelope, gazelle…in Siberia, Alaska, and north of the Arctic circle. Multiple degrees warmer glacial temperatures pervaded both hemispheres. The “long-standing […]

Share this…FacebookTwitterMadagascar’s current drought is perfectly within normal range. Droughts were even worse in the past, 2000 years of precipitation reconstruction data show… Linking Madagascar drought to climate change “scientifically not correct” Not surprisingly, there been lots of climate doomsday talk about the drought and hunger situation in Madagascar, all coming from the usual suspects.

Share this…FacebookTwitterA 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. Two other new studies suggest sea levels were still 0.8 to 1 meter higher than today during the Medieval Warm Period. After the peak […]

New Study: Retreating East Greenland Glaciers Uncover Plant Debris Dating To The 16th - 17th Centuries

New Study: Retreating East Greenland Glaciers Uncover Plant Debris Dating To The 16th – 17th Centuries

Share this...

Share this…FacebookTwitterExposed moss and willow shrubs buried beneath today’s receding East Greenland glaciers can be dated to 400 to 500 years ago, suggesting this period (the early Little Ice Age) was as-warm or warmer than today. It is widely accepted that Greenland’s surface temperatures were several degrees warmer (McFarlin et al., 2018, Axford et al., […]

Share this…FacebookTwitterA new study by Atwood et al (2021) published in the journal of Paleoceanography and Paleoclimatology found there’s “poor agreement” between precipitation reconstructions and model simulations over the past 2000 years. This means future projections made by current models are unreliable.  Die kalte Sonne here reports on a team of scientists who examined 67 […]

Share this…FacebookTwitterThe 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 […]
