Clouds and Climate: Confirmation and Uncertainty

Researchers of the National Space Institute in the Technical University of Denmark (DTU) have confirmed earlier research, finding an inverse relationship between solar activity and cloud formation in Earth's atmosphere. The finding adds to current controversy over the trustworthiness of modern climate models -- models which fail to take this very important physical phenomenon into account.
"A link between the Sun, cosmic rays, aerosols, and liquid-water clouds appears to exist on a global scale," the report concludes. This research, to which Torsten Bondo and Jacob Svensmark contributed, validates 13 years of discoveries that point to a key role for cosmic rays in climate change. In particular, it connects observable variations in the world's cloudiness to laboratory experiments in Copenhagen showing how cosmic rays help to make the all-important aerosols. _SD
An ongoing climate uncertainty relating to clouds, involves the action of dust particles in the atmosphere: Do dust particles increase cloud formation -- thus contributing to reduced insolation and increased cooling?
A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and thus curb climate warming. Research has made little or no progress on this issue. Two scientists from the Max Planck Institute for Meteorology in Hamburg (MPI-M) and the American National Oceanic and Atmospheric Administration (NOAA) report in the journal Nature that the interaction between aerosols, clouds and precipitation is strongly dependent on factors that have not been adequately researched up to now. They urge the adoption of a research concept that will close this gap in the knowledge. (Nature, October 1st, 2009) _WUWT
Another interesting recent finding on how clouds could be affecting climate, comes from the University of Leeds:
Scientists at the University of Leeds have proved that acid in the atmosphere breaks down large particles of iron found in dust into small and extremely soluble iron nanoparticles, which are more readily used by plankton.

This is an important finding because lack of iron can be a limiting factor for plankton growth in the ocean - especially in the southern oceans and parts of the eastern Pacific. Addition of such iron nanoparticles would trigger increased absorption of carbon dioxide from the atmosphere. _SD
So here are three different ways in which clouds and cloud associated aerosols may be significantly affecting the climate -- but climate models do not accurately incorporate these important factors when making their $trillion predictions. And yet, Obama and the United Nations are willing to throw the economies of the industrialised world on the rubbish heap in order to placate computer models which are almost certainly wrong in their predictions.

When are climatologists going to stop pretending that they understand the climate? When are they going to admit that their knowledge is far too limited to base the economic future of the developed world upon them? Do not hold your breath. These climatologists have based their reputations and livelihoods upon the soundness and reliability of their methods and projections. For them to do the right thing now would require a level of character and integrity that is simply beyond them, at this point in the process.

Which means that it is up to you to put political pressure on the funding agencies that pay these pretenders -- to bring them to heel. Make them honest for once. Only pressure from the people who pay the piper can possibly slow down this train wreck to a manageable speed.
