Has NASA Made A Freudian Slip?

In the recent NASA article below, which discusses the effect of aerosols on climate and climate modeling, the ongoing global geoengineering programs are of course never mentioned. We have come to expect such lies of total omission as this is the job description of all “official agencies”. The scientists who work at agencies like NASA are either there to do the bidding of the power structure, or they are threatened into silence and lies. With all this considered, what is most interesting is the photo that NASA “researchers” chose to put into this new article on atmospheric aerosols. Absolutely blatant aerosol spraying is extremely visible in the image, are these “researchers” trying to come clean? Though aerosol saturation is deforming cloud formations all over the globe (also visible in the article’s photo), the undeniable aerosol spraying trails that clearly stand out in the picture are certainly of interest. Why did the authors of this article choose an image with such obvious evidence of aerosol spraying? The article goes on to admit the effect of atmospheric aerosols is double what was previously estimated. They admit the aerosols profoundly affect clouds and precipitation, but as already stated, the geoengineering elephant in the room is never brought up.

Study of Aerosols Stands to Improve Climate Models

Of all the factors that influence Earth’s changing climate, the effect that tiny particles in Earth’s atmosphere called aerosols have on clouds is the least well understood. Aerosols scatter and absorb incoming sunlight and affect the formation and properties of clouds. Among all cloud types, low-level clouds over the ocean, which cover about one-third of the ocean’s surface, have the biggest impact on the albedo, or reflectivity, of Earth’s surface, reflecting solar energy back to space and cooling our planet.

Now a new, comprehensive global analysis of satellite data led by Yi-Chun Chen, a postdoctoral fellow at NASA’s Jet Propulsion Laboratory, Pasadena, California, and a joint team of researchers from JPL and the California Institute of Technology in Pasadena, has quantified how changes in aerosol levels affect these warm clouds over the ocean. The findings appeared Aug. 3 in the advance online version of the journal Nature Geoscience.

Changes in aerosol levels have two main effects — they alter the amount of clouds in the atmosphere and change their properties. Water vapor condenses on aerosol particles into cloud droplets or cloud ice particles, so higher levels of aerosols mean more clouds. With regard to cloud properties, increased aerosol levels can either increase or decrease the amount of liquid water in clouds, depending on whether the clouds are raining or not, the stability of the atmosphere and humidity levels in the upper troposphere. The team analyzed 7.3 million individual data points from multiple satellites in the international constellation of Earth observing satellites known as the Afternoon Constellation, or A-Train, from August 2006 to April 2011 to provide the first real estimate of both effects.

The researchers found each effect to be of similar magnitude – that is, changing the amount of the clouds and changing their internal properties are both equally important in their contribution to cooling our planet. Moreover, they found that the total impact from the influence of aerosols on this type of cloud is almost double that estimated in the latest report of the United Nations’ Intergovernmental Panel on Climate Change.

“These results offer unique guidance on how warm cloud processes should be incorporated in climate models with changing aerosol levels,” said John Seinfeld, the Louis E. Nohl professor and professor of chemical engineering at Caltech.

The study is funded by NASA and the Office of Naval Research.

NASA monitors Earth’s vital signs from land, air and space with a fleet of satellites and ambitious airborne and ground-based observation campaigns. NASA develops new ways to observe and study Earth’s interconnected natural systems with long-term data records and computer analysis tools to better see how our planet is changing. The agency shares this unique knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.
