Share this…FacebookTwitterIt has been assumed COVID lockdowns and their associated reductions in human CO2 emissions would be a “step in the right direction” with regard to climate change mitigation. But a new study finds the particulate (aerosol) pollution reductions from less industrial and transportation activity in Europe during the months of March to May (2020) […]

Share this…FacebookTwitterClimate scientists have been underestimating the role of aerosol-cloud interactions, a new study suggests, thus again throwing climate models into disarray… accurate future climate projections unlikely. A new paper by Hailing et al appearing in Nature Communications found a “significant underestimation of radiative forcing by aerosol–cloud interactions derived from satellite-based methods.

Share this…FacebookTwitterOver the US, the modest change in cloud cover from 1996-2019 predominantly drove the +11.77 W/m² surface solar radiation forcing during 1996-2012 (then -2.35 W/m² from 2013-2019). These “brightening” and “dimming” magnitudes easily overwhelm the values associated with an annual 2 to 2.5 ppm rise in CO2 forcing (0.2 W/m² per decade). When cloud […]

Share this…FacebookTwitterA professor of hydrology from the University of Athens eviscerates the “naïve” paradigm that says the natural state of Earth’s climate is constancy and stability, only changing when an “external agent” (i.e., a rapid increase in fossil fuel emissions ) acts upon it. Instead, (a) water is the main element driving climate and (b) […]

Share this…FacebookTwitterTwo new studies refer to the natural decline in cloud and aerosol reflectivity and consequent rise in incoming solar radiation or sunlight duration as the explanation for warming trends across Europe. CO2 is not even mentioned as a factor in climate change. Scientists point out that, for Europe, “the decrease in cloud cover is […]

Share this…FacebookTwitterCO2’s impact on the total net greenhouse effect (GHE) or longwave (LW) forcing trend has been offset by the dominant impact of cloud cover since the 1980s. It is now widely accepted that changes in clouds, naturally driven by changes in atmospheric circulation, “may be the most important parameter controlling the radiation budget, and, […]

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…FacebookTwitterClouds dominate as the driver of changes in the Earth’s radiation budget and climate. A comprehensive new analysis suggests we’re so uncertain about cloud processes and how they affect climate we can’t even quantify our uncertainty. According to scientists (Song et al., 2016), the total net forcing for Earth’s oceanic atmospheric greenhouse effect (Gaa) […]

Share this…FacebookTwitterEchoing the determination of NASA scientists, a new study suggests the natural variability in cloud cover allowing more solar radiation to be absorbed by the Earth’s oceans drove the 2014-2020 global warming. NASA scientists (Loeb et al., 2018) used satellite data to assess the 2014-2017 warming was driven by a +0.83 W/m² shortwave forcing due […]

Hat-tip: Die kalte Sonne Today global warming alarmists insist blaming climate change on man-made CO2 emissions. Yet, everywhere we look it’s difficult to find any correlation between CO2 and warming. Pre-industrial […]

Share this…FacebookTwitterThe magnitude of claimed global warming since the mid-1800s has tripled from 0.56°C to 1.72°C in the last few years. As recently as 1994, the IPCC claimed global surface temperatures had risen “0.3 to 0.6°C” (0.45°C) since 1861. By 2001, it was changed to 0.61°C warming from 1861 to 2000 (IPCC TAR 2001). Image […]
