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....

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 small, natural fluctuations...

Climate Craziness of the Week: only the ‘cooler’ models are wrong – the rest...
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 are not perfect,” said...

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 a given,...

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 night sky near the...

Tweaking the climate models: Researchers show emissions from forests...
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...

New paper: man-made aerosols have had a net cooling effect since beginning of...
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 reaches the...

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. The cold air acts a bit like the...
