Share this…FacebookTwitterScientists have determined the “optimal thermal conditions” for southwestern Greenland were when summer sea surface temperatures averaged about 12°C from 9,000 to 5,500 years ago, which is substantially warmer than modern summer temperatures (4.0-5.2°C) for this region. A few years ago McFarlin et al. (2018) determined northwestern Greenland was 4-7°C warmer than 1952-2014 during […]

Share this…FacebookTwitterClams’ feeding activity, calcification rates, and overall shell density have declined in concert with decreasing sea surface temperatures and the long-term falling sea level trend since the Holocene peak about 6000 years ago. A team of scientists (Cheli et al., 2021) have suggested Earth’s surface temperatures were “up to 4°C” warmer during the Holocene […]

Share this…FacebookTwitterNortheast China has not been cooperating with the anthropogenic global warming narrative. A few years ago NE China was shown to be up to 7-9°C warmer than present during the Early Holocene (Zheng et al., 2018), when CO2 concentrations drifted around 260 ppm. Image Source: Zheng et al., 2018 Now two new studies indicate […]

Share this…FacebookTwitterFrom 80,000 to 12,000 years ago, when CO2 concentrations lingered near or below 200 ppm, many new or recent studies suggest that when directly comparing region to region, it was as much as 6°C warmer than today even during this ice age period. This has prompted some scientists to “exclude atmospheric pCO2 as a […]

Share this…FacebookTwitterThe survivable temperature thresholds for terrestrial animals in both hemispheres affirm recent millennia were much warmer with less sea ice than today. Antarctica hasn’t warmed in the last 70 years (Singh et al., 2020). The Southern Ocean surrounding Antarctica has been cooling and sea ice has been expanding since 1979 (Fan et al., 2014; […]

Share this…FacebookTwitter In 2020, more than 400 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. Over 400 scientific papers […]

Share this…FacebookTwitterAnother paleo-climatological study reveals that the Mississippi river basin was 2°C warmer than today 700 years ago, another indication that the Medieval Warm Period (MWP) was warmer globally than today. This is bad news for the zealot backers of the man-made global warming hypothesis. Today as atmospheric CO2 concentrations climb beyond 400 ppm, climate […]

Share this…FacebookTwitterMid-Holocene South China Sea maximum temperatures were ~3.5°C warmer (33.5°C vs. today’s 29.9°C) about 5000 yrs ago, when corals experienced an “optimum coral growth period”. There were “numerous coral bleaching episodes” even when temperatures weren’t as high, as coral bleaching is naturally occurring. Key points from a new study (Wang et al., 2021) that […]

Share this…FacebookTwitterPreviously 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 Broadccasting recently reported on a fascinating find in the Swiss Alps: a more than 10,000 year old tree trunk that had been until recently […]

Share this…FacebookTwitterScientists continued defying the “unprecedented” global warming narrative by publishing nearly 150 papers in 2020 that show large regions of the Earth (a) haven’t warmed in recent decades, (b) were as-warm or warmer within the last several centuries, and/or (c) were 1-7°C warmer than today just a few millennia ago. Here is the link […]

Share this…FacebookTwitterIn 2020, scientists continued to publish papers affirming global sea levels are today about 2 meters lower than they were a few thousand years ago. During the last interglacial (~116 to 128 thousand years ago), when CO2 peaked at just 280 ppm but surface temperatures were so much warmer that much less water was […]

Share this…FacebookTwitterA new study affirms coral reefs grow when seas are warm and rising. Growth “shuts off” during colder, falling sea level periods. Consequently, the Great Barrier Reef has experienced growth in the last 150 years – especially in recent decades. During the Last Glacial Maximum (~30,000 to 15,000 years ago), when Great Barrier Reef […]
