(Via the HockeySchtick) A paper published today in Geophysical Research Letters finds that clean air laws which greatly reduced sulfur dioxide emissions explain 81% of the “brightening” of sunshine and…

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…
Oops! 'Dieselification' of London due to CO2 regulations have increased actual air pollution
London’s Dirty Secret: Pollution Worse Than Beijing’s Reader Drew H. submits this story. It’s the law of unintended consequences at work. European Union efforts to fight climate change favored diesel…
Some hype sorting on the claim that Asian pollution is intensifying Pacific Storms
Is Asian Pollution Intensifying Pacific Storms? Separating the Hype from Reality. By Cliff Mass The media over the past week have given a lot of play to a paper in…
JPL Claim: Asian Pollution makes US Storms Worse
Story submitted by Eric Worrall A new study from NASA’s JPL claims Asian air pollution causes worse storms in North America, especially during winter. According to abstract, the study used…
Volcano Activity, Temperature and Response Times:
Guest essay by Neil Catto In view of the possible reasons for the 17-20 year global temperature plateau and further to Willis’ post a couple of weeks ago “Volcanoes Erupt…
A case of the vapours: source of 'climate-active' organic aerosol particles pinned down
From Forschungszentrum Juelich , comes what looks to be a pretty important discovery about how plant emitted aerosols like Great Smoky Mountains National Park haze comes about and grows large…
Study: Volcanoes contribute to recent warming ‘hiatus’
Researchers find models must account for volcanic eruptions to accurately predict climate change. From:MIT Joint Program on the Science and Policy of Global Change By the late 1990s, scientists had…
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…
'Made in China' – US air pollution tied to exports
Chinese air pollution blowing across the Pacific is often caused by manufacturing of goods for export to the US and Europe, according to findings by UC Irvine and others. Study…
Yes, but what about all that extra UHI that water vapor will cause?
Not to mention the water pollution…from Springer Select: To curb China’s haze and air pollution, use water New geoengineering research suggests pollution-control measures inspired by watering a garden A new…
First time in 20 years – more daily record lows than daily highs that were either tied or set in 2013
2013 was a cool year in many ways. Most interestingly, the last year this split between highs and lows happened in the USA, in 1993, we had the eruption from…
Environmental concern disappears with economic instability
From University of Southern California another lesson from the economic train wreck that is Greece; people stop worrying about the environment when you make cleaner fuels too expensive to use.…
Pollen has bigger influences on optical properties of the atmosphere than previously known
From Leibniz-Institut für Troposphärenforschung something that could be a possible negative feedback to CO2. As plants proliferate more due to increased CO2, it follows that pollen load in the atmosphere…
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…
Study: 'Climate change scientists must turn their attention to clean skies'
From the University of Leeds and the department of real problems, comes this paper: Natural aerosols, such as emissions from volcanoes or plants, may contribute more uncertainty than previously thought…
Better US air quality since 1990 offers health benefits
From Brigham Young University: Breathing better, living longer Arden Pope’s students know him as an excellent economics teacher, but some would be surprised to learn that, thanks to him, the…
Is palm oil one of the largest sources on man made aerosols?
From NASA, while we wring our hands over coal fired power plants in the west, the rest of the world seems oblivious to creating even far worse air pollution. Hi-res…
Shocker: Global warming may simply be an artifact of clean air laws
Pollution controls have contributed to a more transparent atmosphere, thus allowing for “…a staggering increase in surface solar radiation of the order of ∼20% over the last decade.” A new…
Ocean warming – it's the aerosols
From CSIRO, but sadly just with modeling, not empirical analysis: Rapid upper ocean warming linked to declining aerosols Australian scientists have identified causes of a rapid warming in the upper…
Wildfire aerosols not handled well in climate modeling
From Los Alamos National Laboratory: Wildfires may contribute more to global warming than previously predicted They suggest that fire emissions could contribute a lot more to the observed climate warming…
Asia's air pollution may be keeping tropical storm activity down
From the Law of Unintended Consequences and The Clean Air Act, comes this bit of news. Since the 1970’s The Clean Air Act has benefited breathing in many American cities…
Whoops! An inconvenient truth for 'global warming makes more rain' advocates: reduced pollution increases rainfall
From the “Department of Unintended Consequences” and Georgia State University comes this oops moment in science. And all that time we are being told by people like Peter Stott that…
Cirrus Cloud seeds identified – will help in climate knowledge
From the Massachusetts Institute of Technology , a fairly important discovery, one that will help us understand the role clouds play in the Earth’s energy balance. The fact that mineral…
