PACific Dust EXperiment «The long range transport of dust and anthropogenic aerosols (e.g, black carbon, organics and sulfates, and air pollution from Eurasia, across the Pacific Ocean, into North America is one of the most wide spread and major pollution events on the planet.

Urban heat island - The relative warmth of a city compared with surrounding rural areas, associated with changes in runoff, the concrete jungle effects on heat retention, changes in surface albedo, changes in pollution and aerosols, and so on.

Stepping back from there, Hansen looks at 1940 and above: «The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but quantitative interpretation has been impossible» That's the excuse and it is laughable.

The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but quantitative interpretation has been impossible because of the absence of adequate aerosol measurements.

We always thought that — apart of course from soot [15 % of climate warming]-- such aerosol pollution creates cooling — as in the case of Chinese sulfur pollution and the Asian (Indian) brown cloud — and that air quality measures over recent decades in North America and Europe are now actually a major cause of increased warming speeds there — as the actual temperature catches up on the «CO2 baseline».

New information from dedicated recent and future field campaigns is expected to shed light on organic aerosol formation processes and how they are altered in the presence of anthropogenic pollution.

The approximate stand - still of global temperature during 1940 - 1975 is generally attributed to an approximate balance of aerosol cooling and greenhouse gas warming during a period of rapid growth of fossil fuel use with little control on particulate air pollution, but satisfactory quantitative interpretation has been impossible because of the absence of adequate aerosol measurements.

In the United States, new research from the City College of New York on the effects of particle pollution on weather patterns around Manhattan has shown that aerosols can either increase or decrease local rainfall, sometimes creating situations where one area will be deluged while a neighboring town will remain dry.

That seems the clearest statement yet of the real problem == is there anything that can replace current levels of air pollution, if high sulfur coal and oil are phased out for respiratory health reasons, that would make up for the loss of the aerosols» negative forcing on global temperature?

In addition to the data from the radiometers, the Berkeley Lab scientists will get supplemental data by taking advantage of a separate, in - depth DOE climate study at the same location, which is using additional instruments and a balloon - borne sounding system to get information on temperature, cloud cover, the density and types of aerosols or pollution particles, heat fluxes and other climate variables like precipitation.
