When assessing the climate-altering effects of downwelling longwave radiation, the root mean square error associated with calculating this value is 29.7 W/m². For some reason, scientists characterize measurements with an observation error this large as “high accuracy”. In an imaginary world where no clouds exist (clear-sky), the surface longwave downward radiation (LWDR) calculated for a […]

Climate models failed to simulate the observed 1970-2014 Pacific Ocean cooling. The 21st century southwestern US megadrought has been linked to this cooling, which “may have been caused by a forced response to greenhouse gas emissions.” A new study provides a fresh look at the circular, self-contradictory reasoning that proponents of the anthropogenic global warming […]

“Clearly, the atmospheric CO2 observation data are not consistent with the climate narrative. Rather, they contradict it.” – Koutsoyiannis, 2024 Per a new study, the Intergovernmental Panel on Climate Change (IPCC) utilizes “inappropriate assumption and speculation,” as well as non-real-world models of “imaginary data,” to claim CO2 emissions derived from fossil fuel burning function “weirdly,” […]

In the 1970s and 1980s ExxonMobil did not know that their reports would be so wrongly misinterpreted in the 2010s. Since 2015, when “investigative journalists” uncovered reports written in the late 1970s by ExxonMobil’s Science Advisor J.P. Black, it has been a common talking point in alarmist circles to insist that “Exxon Knew” about the […]

Evaporation is supposed to increase with warming. But, per a new study (Jin et al., 2024), “observation results around the world have shown that evaporation has been steadily declining since the 1950s.” This is referred to as the anthropogenic global warming “evaporation paradox” problem, where models and assumptions are contradicted by observations. According to the […]

The radiative effect of natural wildfire aerosol forcing alone can be said to fully cancel out the total accumulated forcing from 170 years of CO2 increases in the current climate. It has been estimated that the total change in climate forcing (radiation imbalance) from the 1750 to present CO2 concentration increase has been 1.82 W/m². […]

“Here, we have demonstrated a major discrepancy between observation-based and climate model-based historical trends in near-surface atmospheric water vapor in arid and semi-ari regions.” – Simpson et al., 2024 A new study published in PNAS has demonstrated, once again, that climate models fail to simulate what happens in the real world with regard to fundamental […]

We keep hearing how we’re all supposed to believe in models – even those of highly complex, poorly understood systems like weather and climate. Yet, their outputs keep changing. Hat-tip Snowfan here. Back on December 22, last year, the National Weather Service (NWS) forecast a warmer than normal February 2024: But it has since turned […]

IPCC models rooted in assumptions that we humans can and do control the Atlantic Ocean’s circulation with our daily-activity CO2 emissions have been wrong since the mid-1980s. Why should we still believe in them? The latest IPCC report continues to say it is “very likely” the Atlantic Meridional Ocean Circulation (AMOC), a fundamental climate parameter, […]

See full report at Dr. Roy Spencer As a follow-on to our paper submitted on a new method for calculating the multi-station average urban heat island (UHI) effect on air temperature, I’ve extended that initial U.S.-based study of summertime UHI effects to global land areas in all seasons and produced a global gridded dataset, currently covering the […]

“Despite two decades of advances in many aspects of aerosol-climate science, aerosol climate forcing uncertainty is virtually undiminished. Yet, reducing this uncertainty is critical for any effort to attribute, mitigate, or predict climate changes.” – Kahn et al., 2023 According to a new study, the lower-bound uncertainty in natural aerosol forcing from wildfire smoke, desert […]

For decades rock weathering has been thought to be a net sink in carbon budget models. New research finds rock emissions are a large net source of CO2 to the atmosphere. A few years ago Buesseler et al., 2020 discovered that all of the climate modelers’ previous estimates of global ocean carbon uptake are substantially […]
