Share this… Facebook TwitterFrom 14,000 to 45,000 years ago, when the atmospheric CO2 values were said to be under 200 ppm, California lakes record millennial-scale mean annual air temperature (MAAT) variations of over 12°C and intervals when it was nearly 4°C warmer than modern. Per a new paleotemperature reconstruction (Olson et al., 2023) from a […]

Share this… Facebook TwitterData analysis again reveals the increase in absorbed shortwave forcing has been driving modern climate change since the 1970s. CO2 changes are more of an effect than a cause of temperature increases. Scientists have for years been pointing to the causality sequencing problem inherent in the claim that CO2 is the driver […]

Share this… Facebook TwitterA new study exposes the uncertainty in solar activity reconstructions, but suggests solar models explain climate changes far better than atmospheric CO2 concentrations. Proxy model estimates of the impact of solar variability on climate are highly uncertain. For example, estimations of the increase in solar irradiance over the last 400 years range […]

Share this… Facebook TwitterIn the satellite era scientists have continued to observe the Earth’s total greenhouse effect (which includes effects from greenhouse gases and clouds) exerting an overall negative impact (cooling) on surface temperatures since the 1980s. This rules out both CO2 and an enhanced greenhouse effect as drivers of global warming. Earth’s total greenhouse […]

Share this… Facebook Twitter Surface air CO2 concentrations vary by 100s to 1,000s of ppm within a span of hours to days or weeks across the natural world. The observational evidence suggests these variations are neither driving or even causing temperature changes. According to recent field research (Mungai, 2021) conducted in Kenya, the observed CO2 […]

Share this… Facebook TwitterThe governmental need to portray elevated CO2 as dangerous to humans was recently pitted against the governmental need to require face masks be worn on healthy people. During the height of the COVID-19 pandemic requiring healthy people of all ages to wear face masks in public settings became a common governmental policy […]

Share this… Facebook TwitterSince the early 1990s the conventional assumption, aligned with modeling, has been that a molecule of human CO2 emission stays in the atmosphere – its residence time – for centuries. This fits the anthropogenic global warming (AGW) narrative. But empirical evidence contradicts these model-based assumptions. Residence time is closer to 5-10 years. […]

Share this… Facebook TwitterA warming event that spans only one year, with decades of stable temperatures before and after, would not appear to align with rapidly rising human CO2 emissions or a gradually rising atmospheric CO2 concentration. From 1958 to 2020, as CO2 rose from 320 ppm to 410 ppm, Greenland had a warming period […]

Share this… Facebook Twitter“No evidence is found for any systematic trend in precipitation deficits attributable to anthropogenic climate change.” – O’Connell et al., 2022 In a new study (O’Connell et al., 2022), scientists use a stochastic or random probability distribution analysis to assess whether a signal in global precipitation deficits (droughts) could be linked to […]
