Climate science stance amounts to a gross misrepresentation of reality The DIY way to demystify “greenhouse gas” claims By Fred F. Mueller Part 2 Fig. 1. The sun and the clouds – here a thin cover of high clouds and some aviation chemtrails – are the main driving forces for the energy fluxes determining our […]

Yet another observational study determines changes in Earth’s reflectiveness, or planetary albedo, may be primarily responsible for 21st century climate forcing. Earth’s radiation budget at the top of atmosphere (TOA) is predominantly controlled by internal changes in cloud cover. A declining albedo – linked to declining cloud cover – corresponds to an increase in the […]

Of the warming trends in Poland and greater Europe, “only about 4–5% are explained by an increase in CO2 concentration.” – Marsz et al., 2022 Internal changes to the thermal structure of the ocean transmit decadal-scale changes in the atmospheric circulation and consequent surface air temperature via its modulating impact on the variation in the […]

It so difficult to constrain errors in identifying the cloud impact on Earth’s radiation budget that the orders-of-magnitude smaller radiative impact of CO2 cannot be distinguished from noise. According to a new study using CERES data, the observed biases in detecting the radiative effects of clouds on climate are 2.5 to 6.25 W/m² for longwave […]

A late 2021 study finds water vapor and temperature changes accounted for 90% of the changes in clear-sky downwelling longwave or greenhouse effect forcing since the mid-1980s. CO2 forcing assumed a mere bit-player role. The seminal Feldman et al. (2015) study concluded it takes 10 years and a 22 ppm increase in CO2 to account […]

Scientists have once again affirmed the 2000-2020 total greenhouse effect (longwave) forcing has been declining in recent decades just as absorbed solar radiation has been increasing due to cloud albedo modulation. The latter explains the net positive Earth Energy Imbalance (EEI) and consequent global warming during this period. Recently we detailed the satellite-observed decline in […]

Cloud modulation of shortwave radiation and greenhouse effect forcing has largely been the determining factor in the global warming of the last 45 years. Not CO2. CO2 forcing and its effect on surface temperatures is detailed in analyses of changes in clear-sky radiation only because all-sky radiation effects that include clouds (and the real-world atmosphere […]

A new study reports there has been a -0.3°C cooling in the Southern Ocean since 1982 per multiple observational data sets. The authors detail the “failure of CMIP5 models in simulating the observed SST cooling in the Southern Ocean.” The Southern Ocean is today about 1-2°C colder than it has been for nearly all of […]

A new study finds the modeling-based claim that cloud cover changes are only responding to anthropogenic CO2 forcing as a feedback – and not functioning independently as a forcing – has (again) been contradicted by observations. Since this is a water planet, and since clouds are formed when water vapor turns into water droplets, it […]

It takes 10 years and 22 ppm for CO2 to amass just 0.2 W/m² in total surface energy flux. In contrast, short-wave cloud radiative forcing fluctuations vary in amplitude by ±300 W/m² within hours. Earth’s surface energy imbalance is said to have been positive, +0.6 W/m², during the first decade of this century (Stephens et […]

In 2021, several hundred more 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. These scientific papers affirm the position […]

“Clouds may be the most important parameter controlling the radiation budget, and, hence the Earth climate.” – Sfîcă et al., 2021 It has become more and more common for scientists to attribute modern radiation budget (climate) changes to variations in cloud cover. This should not be surprising. It’s been pointed out (van Heerwaarden et al., […]
