Share this…FacebookTwitterHumans have been recording flowering/bloom dates in China for over 1,000 years. These records affirm modern warmth in China is neither unprecedented nor unusual. Per temperature reconstructions gleaned from phenological records in poems, Central China had multiple 1-2°C warmer decades than 1961-1990 during the 1st millennium (Liu et al., 2021).

Share this…FacebookTwitterPaleoclimate data indicate there was less Arctic sea ice during the pre-industrial period than in modern times, or when CO2 concentrations were 100 ppm lower than today (280 vs. 380 ppm). Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million […]

Share this…FacebookTwitterThe evidence continues to accumulate affirming there is nothing unusual about modern temperature changes – including recent net cooling – throughout large regions of the globe. Cruz et al., 2021 (Argentina) Argentina’s (Tixi Cave) present annual temperature is 13.8°C. It was 3.5°C (17.3°C), 1.7°C (15.5°C), 3°C (16.8°C), and 4.5°C (18.3°C) warmer than today 3496, […]

Share this…FacebookTwitterNew temperature reconstructions using coral skeletons as proxies reveal there has been no apparent net warming in the Great Barrier Reef, central Indian Ocean, and South China Sea since the 19th century – or even in recent decades. Coral skeletons can be used as proxies to reconstruct 1870s-present sea surface temperatures “throughout the Great […]

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 […]

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 […]

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 […]

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 […]

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 […]
