From the University of California – Santa Barbara A UCSB physicist’s experimental results disprove long-held ideas about turbulence In 1941, Russian physicist Andrey Kolmogorov developed a theory of turbulence that…

Link between Cosmic Ray Flux and Global Temperature found
From the paper in PNAS:(h/t to Dr. Leif Svalgaard) Our results suggest weak to moderate coupling between CR and year-to-year changes of GT,” they write. “However, we find that the…
Cloud Feedback
Guest essay by Stan Robertson In a recent post entitled “Changes in Total Solar Irradiance” (http://wattsupwiththat.com/2014/10/25/changes-in-total-solar-irradiance/ ), Willis Eschenbach showed a plot of the solar irradiance that impinges at the…
New paper links warming since 1950 to ENSO and cloud cover variations
John McLean writes of a new paper about the pattern in global average temperature anomalies since 1950 and how they are linked to changes in cloud cover and ENSO: Key…
CERN video: Cloudy climate change – How clouds affect Earth's temperature
This is the second video in the TEDed / CERN series created for the TEDxCERN event held on 25 September 2014. Jasper Kirkby explains why scientists need to understand more…
New paper links Arctic sea ice extent to absorption of sunlight by clouds
The Hockeyschtick writes: A new paper published in the Journal of Geophysical Research Atmospheres finds Arctic sea ice concentrations at the low of each summer are related to absorption of…
BOMBSHELL: Study shows greenhouse gas induced warming dropped for the past 14 years
Paper finds a decrease of IR radiation from greenhouse gases over past 14 years, contradicts expected increase – cloudiness blamed for difference. A paper published in the Journal of Climate…
Stunning Frontal Cloud at Sea
I thought readers might enjoy this photo. This frontal cloud formed from a northeast wind shift and lifting of humid ocean air enough to cool it below the dew point.…
New paper: man-made aerosols have had a net cooling effect since beginning of industrial revolution
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…
