More aerosols, means more clouds, which means cooler temperatures. Now that we are cleaning up aerosols worldwide, this may explain why the Earth is getting slightly warmer – more sunlight…

Tweaking the climate models: Researchers show emissions from forests influence very first stage of cloud formation
Clouds are the largest source of uncertainty in present climate models. Much of the uncertainty surrounding clouds’ effect on climate stems from the complexity of cloud formation. New research from…
Noctilucent clouds on the increase, climate change will likely be blamed
Of course, it might just be a negative feedback at work. From NASA: Appearance of Night-Shining Clouds Has Increased First spotted in 1885, silvery blue clouds sometimes hover in the…
We don't know clouds
Too many variables like clouds to model future climate with precision Guest essay by Rolf Westgard A new United Nations report suggests an imminent danger from global warming. It states…
Picture of how our climate is affected by greenhouse gases is a 'cloudy' one
Cloud cover is a major forcing, and uncertain, say researchers from the Hebrew University, US and Australia Jerusalem, Jan. 26, 2014 – The warming effect of human-induced greenhouse gases is…
Climate Craziness of the Week: only the 'cooler' models are wrong – the rest say 4ºC of warming by 2100
From the University of New South Wales and Dr. Steven Sherwood: “Climate sceptics like to criticise climate models for getting things wrong, and we are the first to admit they…
Study: lack of cloud physics biased climate models high
The Hockey Schtick brings this to our attention. It seems Dr. Roy Spencer was prescient with his observation: “The most obvious way for warming to be caused naturally is for…
Real pollution (not 'carbon' pollution) increases storm clouds
From the Pacific Northwest National Laboratory: A common theme among climate alarmists is that the wrongly named ‘carbon pollution’ aka carbon dioxide, increases the frequency and intensity of storms. Observational data…
Upwelling Longwave Over The Ocean
Guest Post by Willis Eschenbach To continue my investigations utilizing the CERES satellite dataset of top of atmosphere radiation, here is a set of curious graphs. The first one is…
Chemtrails or Contrails? Another Alarmist Issue Without Scientific Context
NOTE: like with the essay Saturday about isotasy/glacial rebound being a myth, I don’t think the chemtrails idea has any merit whatsoever. Dr. Tim Ball points out more bad science…
Atmosphere's emission fingerprint affected by how clouds are stacked
From AGU highlights: Clouds, which can absorb or reflect incoming radiation and affect the amount of radiation escaping from Earth’s atmosphere, remain the greatest source of uncertainty in global climate…
Solar gains in Spain may cause warmists pain
From the FECYT – Spanish Foundation for Science and Technology via Eurekalert comes this interesting note about solar forcing. It seems there’s a 2.3% per decade increase in solar radiation…
Climate lab in a container on the high seas
From the Brookhaven National Laboratory: Yearlong MAGIC Climate Study Launches Climate instruments mounted aboard the Horizon Spirit container ship begin taking data The Horizon Spirit makes the round trip between…
Some confirmation of Spencer's cloud hypothesis – it is getting less cloudy and warmer at the same time
A new paper just published in the Journal of Climate finds that global cloudiness has decreased over the past 39 years from between 0.9 to 2.8% by continent as shown…
New paper shows negative cloud feedback associated with SAM
A paper published Friday in the Journal of Geophysical Research (GRL) finds that a known and natural atmospheric oscillation, the Southern Annular Mode or SAM, is correlated with observed increases…
Forcing or Feedback?
Guest Post by Willis Eschenbach I read a Reviewer’s Comment on one of Richard Lindzen’s papers today, a paper about the tropics from 20°N to 20°S, and I came across…
Spencer’s posited 1-2% cloud cover variation found
In a nutshell, with a −1.6%per decade change in cloud cover during 1954–2005, it becomes a climate forcing. While China is not the world, it bears consideration. The Hockey Schtick…
Crowdsourced Climate Complexity – Compiling the WUWT Potential Climatic Variables Reference Page

I suppose if I truly want to take the weekend off, I’ll have to ditch my smartphone. These photos from the Facebook page of the Panhandle Helicopter Service in Panama…
The Ridiculousness Continues – Climate Complexity Compiled
