The higher temperatures are clearly attributable to a reduction in cloud cover, not CO2 The DIY way to demystify “greenhouse gas” claims Rapidly rising temperatures and drought in parts of central Europe are caused by a long-term trend of receding cloud cover. Fewer clouds result in increased solar energy influx and reduced downpour. Both factors […]

The claim that rising global surface temperatures will induce more storm activity is contradicted by observations. Scientists reporting on the contrasting albedo effects of clouds in the Northern vs. Southern Hemispheres (Blanco et al., 2023) assess clouds have a “profound” effect on the global radiation budget and thus our climate. The Southern Hemisphere is cloudier […]

Data 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 of temperature changes. […]

In 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 effect impact on […]

Do you feel helpless when trying to assess the veracity of “climate doom is looming” claims we are constantly bombarded with? For ordinary citizens, it seems nearly impossible to tell right from wrong when it comes to assess such claims. Don’t give up trying to understand the relevant basics, there is a rather simple way […]

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 […]
