17 More Studies Show No Unusual Warming Trend In Recent Centuries…And A Warmer Holocene

The 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, 1656, 656, and 160 years before present, respectively. So ~1860 was 4.5°C warmer.

Campbell-Heaton et al., 2021 (Arctic Canada)

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 (1981-2016) average -33°C in the Canadian Arctic’s Eureka Sound Lowlands. About 9000 to 10,000 years ago, ground surface temperatures reached -18°C at this location, which is 15°C warmer than present. Winter air temperatures, were, on average, 6-8°C warmer than today at this time too.

Dodson et al., 2021 (northeastern China)

“Zheng et al. (2018) measured organic compounds in peats from northeast China and estimated that temperatures were ?5–7°C warmer than today, and that soil moisture increased from the early to late Holocene. Zhang et al. (2018) used two stalagmite records to infer that monsoon intensity was greater in the early Holocene in north China. The current mean July temperatures are about 20–21°C, however, these are estimated to be above 26°C between 8,500 and 4,200 cal yr BP.”
