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 finds from 800,000 observations a significant decrease in longwave infrared radiation from increasing greenhouse gases over the 14 year period 1996-2010 in the US Great…

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 leading edge of an airplane wing. Taken about 5 miles offshore of Seaside Heights New Jersey, 8am…

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 reaches the surface A paper published today in Science claims the transition from “pristine” to “slightly polluted” atmosphere at the beginning of the industrial revolution…

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 scientists at the CLOUD experiment at CERN, including Carnegie Mellon’s Neil Donahue, sheds light on new particle formation — the very first step of cloud…

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 that without drastic action we may have “to develop the ability to suck greenhouse gases out of the atmosphere and store them underground”. Minnesota already…
