A new study dispels the claim that coral reefs are at risk from modern environmental changes or rates. From about 8000 to 6000 years ago the Great Barrier Reef (GBR) relative sea levels were ~2 meters higher and seas were rising at rates of ~6 to 7 meters per millennium (6-7 mm/yr). The Early Holocene […]

Yet another region has not been affected by CO2-induced “global” warming. A new biomarker temperature reconstruction (Szabó et al., 2024) spanning the last 2000 years reveals South Carpathian mean July temperatures varied from 13.4°C to 16.9°C throughout the Common Era, with an identifiable Little Ice Age and Medieval Warm Period. The mean summer temperature during […]

“…elevated CO2 concentrations not only boosted vegetation growth through the fertilizer effect but also indirectly enhanced water availability [reducing drought risk] by improving water use efficiency.” – Song et al., 2024 One of the more commonly-stated concerns linked to “global warming” is that sweltering heat will parch the terrestrial landscape (browning), limit vegetation growth, and […]

“Today there is no evidence that B. Gaini lives in permanently frozen lakes.” – Roman et al., 2024 Image Source: Public Domain Image According to a new study (Roman et al., 2024), fairy shrimp Branchinecta gaini occupied the Antarctic Peninsula’s seasonally ice-free Monolithic Lake throughout much of the last 2000 years. There were “longer ice-free […]

Scientists do not even mention CO2 concentration changes as a factor in ocean warming. A new study reveals the limit of the greenhouse gas-induced longwave radiative impact extends only to the ~10 μm (0.01 mm) skin layer – the ocean-air interface – and no deeper. Determining the sea surface temperature (SST) variation at this skin […]

“…higher atmospheric CO2…triggers…increased vegetation production and a greener landscape” – Chen et al., 2024 Plant transpiration is vital to plant growth and terrestrial ecosystems. The rising CO2 trend over the last 30 years (1990-2020) has been the primary driver of planetary greening, or increases in Leaf Area Index (LAI). The greening, in turn, is predominantly […]

A new study reports Estonia’s climate was 2-3°C warmer and sea levels were 10-20 m higher ~7,300 years ago. Comparing detailed maps from 1915 and 1904 to 2004 and 2021 aerial images reveals the sea waters have receded from the coasts of Estonia so acutely that lagoons are fast disappearing, islands are being transformed into […]

There were millennia during the past glacial (when CO2 levels were under 200 ppm) that were as warm or warmer than today. Four central Europe reconstructions, using collected evidence from disparate biomarkers, indicate there were periods (for example, 54,000 to 51,000 years ago, the Bølling–Allerød interstadial, 14,700 years ago) during the last glacial when temperatures […]

Global warming was supposed to open up Arctic region shipping routes, making the Northwest Passage easier and less risky to traverse. Per a new study, the opposite has happened. As we reported earlier this year, while a declining trend in Arctic sea ice was observed from the 1990s to 2007, there has been no trend […]

Popular claims that CO2 changes drive temperature changes currently or throughout the distant past “are based on imagination and climate models full of assumptions.” A comprehensive new study details a stochastic assessment determination of the sequencing of CO2 variations versus temperature variations since the 1950s, over the last 2,000 years (the Common Era), and throughout […]

A new study comprehensively eviscerates a 57-year-old modeling paper upon which nearly the entirety of the IPCC’s CO2-drives-climate paradigm is based. Dr. Roy Clark has published a new 73-page study that rips apart the Manabe and Wetherald (1967) paper (MW67) that effectively hatched the IPCC-popularized concepts of CO2 climate sensitivity, radiative forcing, and positive/negative feedbacks […]

Instead, warmth and elevated CO2 are a boon for humanity. A new peer-reviewed paper published in The American Journal of Economics and Sociology (May and Crok, 2024) counters the prevailing “wisdom” that says a warmer climate and greener vegetation are problematic. The authors detail the horrors of the much colder Little Ice Age that destroyed […]
