This is something which sceptics have been saying for years. The radiative forcing from changes in cloud cover is at least an order of magnitude greater than the miniscule alleged contribution from GHGs. Anthropogenic forcing is entirely lost in the noise of natural variability plus limitations upon observations, yet climate alarmist 'scientists' claim to be able to discern it with precision. This is fraud. Here is what the Loeb abstract says:

"Observations from the Clouds and the Earth’s Radiant Energy System (CERES) show a marked increase in Earth’s energy imbalance (EEI) since 2000. At the same time, we’ve seen marked changes in numerous geophysical variables that influence EEI. While observations alone cannot quantify the anthropogenic and natural contributions to changes in these quantities, they can provide insight into how changes in different components of the climate system have led to the observed EEI trend. Using additional data from MODIS, CALIPSO, Cloudsat, and reanalysis, we find the increase in EEI to be due to decreased reflection by clouds and sea-ice, which cause a pronounced increase absorbed solar radiation (ASR), and a decrease in outgoing longwave radiation (OLR) due to increases in trace gases and water vapor. The ASR increases are largest over the subtropics and mid-latitudes in regions with decreases in low and middle cloud fraction, which likely occur in response to observed increases in sea-surface temperature (SST) in those locations. We diagnose the SST changes by performing an ocean mixed layer energy budget analysis at regional, hemispheric, and global scales using TOA and surface radiation observations from CERES, SST and temperature/humidity fields from ERA-5, and ocean mixed layer depth from ocean reanalysis. This analysis suggests that heating of the mixed layer and the subsequent increase in SST stems from ocean mixing/advection rather than from surface forcing."

As clear as day. Whilst there may be some increase in radiative forcing due to GHGs, EEI since 2000 has been driven primarily by changes in cloud cover and ice cover. The ocean heat content (claimed by alarmists to be definitive evidence of man's influence) has increased as a result of the mixing and advection of the extra solar energy hitting the surface (think El Nino/La Nina). Schmidt and others CANNOT claim to have eliminated these very large natural changes in order to discern the tiny forcing due to anthropogenic GHGs. Man-made climate change is a fraud.

My father has been a professor of electrical engineering for nearly 60 years. He has a very long CV of publications in top journals, and previous consultancies for Motorola, Archer Daniels Midland, NASA, Argonne National Labs, and others. He's an expert in informations theory, probability & statistics, and modelling.

When he did a deep look into the climatology literature he noticed the regression models using atmospheric temps, and estimates of human-produced CO2 in the literature were invalid. The researchers made a sophomoric error in that they did not transform the nonstationary data (time-varying mean) before doing the regression as MUST be done.

He used the same data, and submitted a paper for publication to the IPCC. For the first, and only time in his career he had to call a journal editor just to get his submission "peer-reviewed." The response was basically fuck off we're not interested.

He had been in touch with MIT's Richard Lindzen and Lindzen who told him he'd never get his paper published. Around that time my father had also signed a letter, which at the time he signed it, had 5,000 signatures from academics, and other experts questioning the head long rush into global warming. That letter did not ever get any publicity.

Anthropogenic climate change is a complete scam. There's ZERO credible evidence for it.
