Scientists have found evidence that the coastal land area grew (prograded) by 120 meters from 1900 to 1985 at a study site in central Denmark. Per a new study, relative sea levels (RSL) in central Denmark were “~4.5 m higher than present between c. 6.6 and 5.9 ka ago.” After this highstand, RSL declined towards […]

In 2023, hundreds of scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. There are significant limitations and uncertainties inherent […]

Arctic regions with 6+ months of sea ice coverage today were ice-free nearly year-round 9,000 to 5,000 years ago (2°C warmer) and 130,000 to 115,000 years ago (7-8°C warmer). And yet polar bears survived these periods. Per a new study, today’s Scandinavian Arctic climate is so cold it is actually “comparable” to that of the […]

According to a new study, eastern Mediterranean summer temperatures were 1.5°C to 3°C “greater than the present” from about 11,000 to 7,000 years ago, when CO2 levels were approximately 265 ppm. Then the temperatures “followed a gradual decline towards present-day conditions”. “The MTWA also showed an increasing trend from 9 ka and reached a maximum of […]

Warmer sea surface temperatures are associated with coral growth, not decline. According to a new study, coral growth was slow during the ~1°C colder Little Ice Age (LIA), but grew rapidly as sea surface temperatures (SSTs) warmed after 1850. Warmth is associated with coral growth, whereas colder SSTs are linked to growth rate decline. “The […]

Comprehensive data analysis shows relative sea levels were anywhere from 1 to 7 meters (~3.9 m) higher than present throughout the Mid-Holocene at 15 of 16 assessed sites across Southeast Asia. A new study (Li et al., 2023) compiles highstand records from sites spanning Thailand, Vietnam, Singapore, Malaysia, Borneo, Sunda Shelf, Makassar Strait…and indicates that […]

“…by about 10 kyr ago, regional MST values consistently approached or exceeded today’s value of about 23°C” – Baxter et al., 2023 According to a new temperature reconstruction published in Nature, the Horn of Africa and “global tropics as a whole” were “1.6°C warmer than today” throughout the Early and Middle Holocene. This is “consistent […]

Millennial-scale Arctic sea ice reconstructions do not corroborate alarmist claims of unprecedented sea ice losses in modern times. Using sea ice biomarker proxy (IP25), scientists (Kolling et al., 2023) have determined that the sea ice extent in the Labrador Sea was nearly absent throughout the year (close to 0.0 μg/gTOC) for much of the last […]

The timing of the dramatic Antarctic sea ice decline during the last deglaciation suggests solar forcing and sea ice retreat “instigated” century-scale climate warming and atmospheric CO2 change. This would appear to challenge the perception CO2 plays a causal role in glacial-interglacial sea ice and climate changes. From ~21,000 to 19,500 years ago, when CO2 […]

Yet another region of the world fails to cooperate with “global” warming instructions. New research (Zhang et al., 2023) finds the sea ice extent has undergone an overall increasing trend from 2005-2021 in the Sea of Japan, Yellow Sea, and Bohai Sea. “Over the past 17 years, the maximum sea ice extent in the marginal […]

Paleoclimate studies continue to undermine claims of “unprecedented” global warming in the modern era. A new temperature reconstruction (Oliveira Silva Muraja et al., 2023) for Brazil reveals there has been no net modern warming since the 1400s. Image Source: Oliveira Silva Muraja et al., 2023 Another new temperature reconstruction (Yue et al., 2023) indicates there […]
