Share this…FacebookTwitterA new study (Stallinga, 2020) assesses the climate sensitivity to rising CO2 concentrations is just 0.0014°C per ppm. Dr. Peter Stallinga has published a comprehensive analysis of the Earth’s greenhouse effect. He finds an inconsequential role for CO2. Doubling CO2 from 350 to 700 ppm yields a warming of less than 0.5°C (500 mK). […]

Share this…FacebookTwitterEarth’s atmosphere is made of 78% nitrogen (N2) and 21% oxygen (O2). The “consensus” view is N2 and O2 are not greenhouse gases (GHGs) and don’t absorb infrared radiation (IR). But scientists have been saying N2 absorbs and radiates IR since 1944 and more recent (2012, 2016) studies have found N2 and O2 are […]

Share this…FacebookTwitterScientists (Syring et al., 2020) find almost sea ice-free conditions pervaded a much warmer northern Greenland region during the Early Holocene. Arctic sea ice extent has “continuously” grown for ~4800 years, with modern conditions a bit lower than the peak of the last few centuries. Image Source: Syring et al., 2020 In a new […]

Share this…FacebookTwitterA new 5680-year tree-ring temperature reconstruction for southern South America (Lara et al., 2020) reveals (a) no clear warming trend in recent decades, and (b) the 18th and 19th centuries (and many centennial-scale periods from the last 5680 years) had much warmer temperatures than today. Image Source: Lara et al., 2020 In addition to […]

Share this…FacebookTwitterIn 2019, more than 440 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. Image Source: Collins et al., […]

Share this…FacebookTwitterAnother study finds CO2’s greenhouse effect contribution and climate sensitivity are much smaller than claimed by the IPCC and proponents of anthropogenic global warming. Ollila (2019) reconfigures the “consensus”-derived greenhouse effect radiation values and finds (a) LW absorption only adds 45% to Earth’s present atmospheric greenhouse effect, (b) water vapor dominates (76.4%) the total […]

Share this…FacebookTwitterA new reconstruction (Martin et al., 2020) shows peak mean annual temperatures (14°C) were 7°C warmer than today (7°C, 2009-2017) ~7800 years ago in France. In the last 200 years temperatures have fallen by ~3°C. Image Source: Martin et al., 2020 Another new study (Caillouet et al., 2019) finds little to no signficant climate […]

Share this…FacebookTwitterRapid cooling in the North Atlantic has reversed regional sea level changes and has apparently spread to the Greenland ice sheet. Image Source: Chafik et al. (2019) Despite stressing global sea level rise is worrisome and due to anthropogenic warming, Chafik et al. (2019) report a distinct cooling trend in the North Atlantic that […]

Share this…FacebookTwitterThe onslaught of paleoclimate evidence for warmer-than-now Mid-Holocene climates – when the Earth’s sea levels were meters higher than they are today – stormed through 2019. There were 107 scientific papers published this past year indicating today’s warmth isn’t even close to being unusual or unprecedented when compared to the climates of the last […]

Share this…FacebookTwitterThe current furor about an alleged connection between climate change, CO2 emissions, and Australian fires finds no support in the scientific literature. According to scientists, rising CO2 concentrations reduce fire ignition and burned area. Further, both global-scale and Australian fires were far more pervasive during the colder Little Ice Age. Here’s what the scientific […]

Share this…FacebookTwitterFundamental tenets of the CO2 greenhouse effect hyphothesis aren’t supported by real-world, observed evidence. Image Source: Kennedy and Hodzic, 2019 I. CO2 warms the planet by 7.2°C? According to the IPCC and other sources, when CO2’s atmospheric concentration ranges between 0.03% and 0.04% (300-400 parts per million, or ppm), it literally warms the air […]

Share this…FacebookTwitterAccording to a new paper, the Earth’s ocean heat content time derivative (OHCTD) has been decreasing (-0.26 W/m²/decade) since 2000, coinciding with a similar deficit in the Earth’s energy imbalance (EEI). The authors acknowledge such trends are “surprising” considering greenhouse gas emissions have risen. Image Source: Dewitte et al., 2019 Earth’s energy budget imbalanced? […]
